How to group RadioButton from different LinearLayouts?

I was wondering if is possible to group each single RadioButton in a unique RadioGroup maintaining the same structure. My structure look like this:

• LinearLayout_main
  • LinearLayout_1 * RadioButton1
  • LinearLayout_2 * RadioButton2
  • LinearLayout_3 * RadioButton3

As you can see, now each RadioButton is a child of different LinearLayout. I tried using the structure below, but it doesn't work:

• Radiogroup

• LinearLayout_main - LinearLayout_1 * RadioButton1 - LinearLayout_2 * RadioButton2 - LinearLayout_3 * RadioButton3

It seems that the good people at Google/Android assume that when you use RadioButtons, you don't need the flexibility that comes with every other aspect of the Android UI/layout system. To put it simply: they don't want you to nest layouts and radio buttons. Sigh.

So you gotta work around the problem. That means you must implement radio buttons on your own.

This really isn't too hard. In your onCreate(), set your RadioButtons with their own onClick() so that when they are activated, they setChecked(true) and do the opposite for the other buttons. For example:

class FooActivity {

	RadioButton m_one, m_two, m_three;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		...
		m_one = (RadioButton) findViewById(R.id.first_radio_button);
		m_two = (RadioButton) findViewById(R.id.second_radio_button);
		m_three = (RadioButton) findViewById(R.id.third_radio_button);
		
		m_one.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				m_one.setChecked(true);
				m_two.setChecked(false);
				m_three.setChecked(false);
			}
		});
		
		m_two.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				m_one.setChecked(false);
				m_two.setChecked(true);
				m_three.setChecked(false);
			}
		});

		m_three.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				m_one.setChecked(false);
				m_two.setChecked(false);
				m_three.setChecked(true);
			}
		});

		...		
	} // onCreate()	

}

Yeah, I know--way old-school. But it works. Good luck!

Use this class that I created. It will find all checkable children in your hierarchy.

import java.util.ArrayList;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Checkable;
import android.widget.LinearLayout;

public class MyRadioGroup extends LinearLayout {

private ArrayList<View> mCheckables = new ArrayList<View>();

public MyRadioGroup(Context context) {
	super(context);
}

public MyRadioGroup(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public MyRadioGroup(Context context, AttributeSet attrs, int defStyle) {
	super(context, attrs, defStyle);
}

@Override
public void addView(View child, int index,
		android.view.ViewGroup.LayoutParams params) {
	super.addView(child, index, params);
	parseChild(child);
}

public void parseChild(final View child)
{
	if(child instanceof Checkable)
	{
		mCheckables.add(child);
		child.setOnClickListener(new OnClickListener() {
			
			public void onClick(View v) {
				for(int i = 0; i < mCheckables.size();i++)
				{
					Checkable view = (Checkable) mCheckables.get(i);
					if(view == v)
					{
						((Checkable)view).setChecked(true);
					}
					else
					{
						((Checkable)view).setChecked(false);
					}
				}
			}
		});
	}
	else if(child instanceof ViewGroup)
	{
		parseChildren((ViewGroup)child);
	}
}

public void parseChildren(final ViewGroup child)
{
	for (int i = 0; i < child.getChildCount();i++)
	{
		parseChild(child.getChildAt(i));
	}
}
}

Well, I wrote this simple class.

Just use it like this:

// add any number of RadioButton resource IDs here
GRadioGroup gr = new GRadioGroup(this, 
    R.id.radioButton1, R.id.radioButton2, R.id.radioButton3);

or

GRadioGroup gr = new GRadioGroup(rb1, rb2, rb3);
// where RadioButton rb1 = (RadioButton) findViewById(R.id.radioButton1);
// etc.

You can call it in onCreate() of Activity for example. No matter which RadioButton you click, the others will become unchecked. Also, no matters, if some of RadioButtons are inside of some RadioGroup, or not.

Here's the class:

package pl.infografnet.GClasses;

import java.util.ArrayList;
import java.util.List;

import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewParent;
import android.widget.RadioButton;
import android.widget.RadioGroup;

public class GRadioGroup {

	List<RadioButton> radios = new ArrayList<RadioButton>();

	/**
	 * Constructor, which allows you to pass number of RadioButton instances,
	 * making a group.
	 * 
	 * @param radios
	 *            One RadioButton or more.
	 */
	public GRadioGroup(RadioButton... radios) {
		super();

		for (RadioButton rb : radios) {
			this.radios.add(rb);
			rb.setOnClickListener(onClick);
		}
	}

	/**
	 * Constructor, which allows you to pass number of RadioButtons 
	 * represented by resource IDs, making a group.
	 * 
	 * @param activity
	 *            Current View (or Activity) to which those RadioButtons 
	 *            belong.
	 * @param radiosIDs
	 *            One RadioButton or more.
	 */
	public GRadioGroup(View activity, int... radiosIDs) {
		super();

		for (int radioButtonID : radiosIDs) {
			RadioButton rb = (RadioButton)activity.findViewById(radioButtonID);
			if (rb != null) {
				this.radios.add(rb);
				rb.setOnClickListener(onClick);
			}
		}
	}

	/**
	 * This occurs everytime when one of RadioButtons is clicked, 
	 * and deselects all others in the group.
	 */
	OnClickListener onClick = new OnClickListener() {

		@Override
		public void onClick(View v) {

			// let's deselect all radios in group
			for (RadioButton rb : radios) {

				ViewParent p = rb.getParent();
				if (p.getClass().equals(RadioGroup.class)) {
					// if RadioButton belongs to RadioGroup, 
					// then deselect all radios in it 
					RadioGroup rg = (RadioGroup) p;
					rg.clearCheck();
				} else {
					// if RadioButton DOES NOT belong to RadioGroup, 
					// just deselect it
					rb.setChecked(false);
				}
			}

			// now let's select currently clicked RadioButton
			if (v.getClass().equals(RadioButton.class)) {
				RadioButton rb = (RadioButton) v;
				rb.setChecked(true);
			}

		}
	};

}

Here's my solution based on @lostdev solution and implementation of RadioGroup. It's a RadioGroup modified to work with RadioButtons (or other CompoundButtons) that are nested inside child layouts.

You can use it in your layout the same way as you would a regular RadioGroup with the exception that it works with nested RadioButton views as well:

<RecursiveRadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp"
    android:layout_marginBottom="16dp"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    android:orientation="horizontal">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="vertical">

        <RadioButton
            android:id="@+id/rbNotEnoughProfileInfo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Not enough profile information"/>

        <RadioButton
            android:id="@+id/rbNotAGoodFit"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Not a good fit"/>

        <RadioButton
            android:id="@+id/rbDatesNoLongerAvailable"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Dates no longer available"/>

    </LinearLayout>

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="vertical">

        <RadioButton
            android:id="@+id/rbOther"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Other"/>

        <android.support.v7.widget.AppCompatEditText
            android:id="@+id/etReason"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@+id/tvMessageError"
            android:textSize="15sp"
            android:gravity="top|left"
            android:hint="Tell us more"
            android:padding="16dp"
            android:background="@drawable/edit_text_multiline_background"/>
    </LinearLayout>

</RecursiveRadioGroup>

This solution has not been posted so posting :

Step 0: Create a CompoundButton previousCheckedCompoundButton; as global variable.

Step 1: Create OnCheckedChangedListener for radio buttons

CompoundButton.OnCheckedChangeListener onRadioButtonCheckedListener = new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (!isChecked) return;
            if (previousCheckedCompoundButton != null) {
                previousCheckedCompoundButton.setChecked(false);
                previousCheckedCompoundButton = buttonView;
            } else {
                previousCheckedCompoundButton = buttonView;
            }
        }
    };

Step 3: add listener to all radio buttons:

radioButton1.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton2.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton3.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton4.setOnCheckedChangeListener(onRadioButtonCheckedListener);

Thats it!! your'e done.

Sigh.. Really blame that Android lacks such a basic functionality.

Adapted from @ScottBiggs answer, here's the possibly shortest way to do it with Kotlin:

var currentSelected = button1
listOf<RadioButton>(
    button1, button2, button3, ...
).forEach {
    it.setOnClickListener { _ ->
        currentSelected.isChecked = false
        currentSelected = it
        currentSelected.isChecked = true
    }
}

You can use this simple RadioGroup extension code. Drop whatever layouts/views/images in it along with the RadioButtons and it will work.

It contains selection callback which returns the selected RadioButton with its index and you can set selection programatically by index or id:

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.RadioButton;
import android.widget.RadioGroup;

import java.util.ArrayList;

public class EnhancedRadioGroup extends RadioGroup implements View.OnClickListener {

    public interface OnSelectionChangedListener {
        void onSelectionChanged(RadioButton radioButton, int index);
    }

    private OnSelectionChangedListener selectionChangedListener;
    ArrayList<RadioButton> radioButtons = new ArrayList<>();

    public EnhancedRadioGroup(Context context) {
        super(context);
    }

    public EnhancedRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
        super.onLayout(changed, l, t, r, b);
        if (changed) {
            getRadioButtons();
        }
    }

    private void getRadioButtons() {
        radioButtons.clear();
        checkForRadioButtons(this);
    }

    private void checkForRadioButtons(ViewGroup viewGroup) {
        if (viewGroup == null) {
            return;
        }
        for (int i = 0; i < viewGroup.getChildCount(); i++) {
            View v = viewGroup.getChildAt(i);
            if (v instanceof RadioButton) {
                v.setOnClickListener(this);
                // store index of item
                v.setTag(radioButtons.size());
                radioButtons.add((RadioButton) v);
            }
            else if (v instanceof ViewGroup) {
                checkForRadioButtons((ViewGroup)v);
            }
        }
    }

    public RadioButton getSelectedItem() {
        if (radioButtons.isEmpty()) {
            getRadioButtons();
        }
        for (RadioButton radioButton : radioButtons) {
            if (radioButton.isChecked()) {
                return radioButton;
            }
        }
        return null;
    }

    public void setOnSelectionChanged(OnSelectionChangedListener selectionChangedListener) {
        this.selectionChangedListener = selectionChangedListener;
    }

    public void setSelectedById(int id) {
        if (radioButtons.isEmpty()) {
            getRadioButtons();
        }
        for (RadioButton radioButton : radioButtons) {
            boolean isSelectedRadioButton = radioButton.getId() == id;
            radioButton.setChecked(isSelectedRadioButton);
            if (isSelectedRadioButton && selectionChangedListener != null) {
                selectionChangedListener.onSelectionChanged(radioButton, (int)radioButton.getTag());
            }
        }
    }

    public void setSelectedByIndex(int index) {
        if (radioButtons.isEmpty()) {
            getRadioButtons();
        }
        if (radioButtons.size() > index) {
            setSelectedRadioButton(radioButtons.get(index));
        }
    }

    @Override
    public void onClick(View v) {
        setSelectedRadioButton((RadioButton) v);
    }

    private void setSelectedRadioButton(RadioButton rb) {
        if (radioButtons.isEmpty()) {
            getRadioButtons();
        }
        for (RadioButton radioButton : radioButtons) {
            radioButton.setChecked(rb == radioButton);
        }
        if (selectionChangedListener != null) {
            selectionChangedListener.onSelectionChanged(rb, (int)rb.getTag());
        }
    }
}

Use it in you layout xml:

    <path.to.your.package.EnhancedRadioGroup>
       Layouts containing RadioButtons/Images/Views and other RadioButtons
    </path.to.your.package.EnhancedRadioGroup>

To register to the callback:

        enhancedRadioGroupInstance.setOnSelectionChanged(new EnhancedRadioGroup.OnSelectionChangedListener() {
            @Override
            public void onSelectionChanged(RadioButton radioButton, int index) {
                
            }
        });

I created these two methods to solve this problem. All you have to do is pass the ViewGroup where the RadioButtons are (could be a RadioGroup, LinearLayout, RelativeLayout, etc.) and it sets the OnClick events exclusively, that is, whenever one of the RadioButtons that is a child of the ViewGroup (at any nested level) is selected, the others are unselected. It works with as many nested layouts as you would like.

public class Utils {
	public static void setRadioExclusiveClick(ViewGroup parent) {
		final List<RadioButton> radios = getRadioButtons(parent);
		
		for (RadioButton radio: radios) {
			radio.setOnClickListener(new OnClickListener() {
				
				@Override
				public void onClick(View v) {
					RadioButton r = (RadioButton) v;
					r.setChecked(true);
					for (RadioButton r2:radios) {
						if (r2.getId() != r.getId()) {
							r2.setChecked(false);
						}
					}
					
				}
			});
		}
	}
	
	private static List<RadioButton> getRadioButtons(ViewGroup parent) {
		List<RadioButton> radios = new ArrayList<RadioButton>();
		for (int i=0;i < parent.getChildCount(); i++) {
			View v = parent.getChildAt(i);
			if (v instanceof RadioButton) {
				radios.add((RadioButton) v);
			} else if (v instanceof ViewGroup) {
				List<RadioButton> nestedRadios = getRadioButtons((ViewGroup) v);
                radios.addAll(nestedRadios);
			}
		}
		return radios;
	}
}

Usage inside an activity would be like this:

ViewGroup parent = findViewById(R.id.radios_parent);
Utils.setRadioExclusiveClick(parent);

I've written my own radio group class that allows to contain nested radio buttons. Check it out. If you find bugs, please let me know.

/**
 * This class is used to create a multiple-exclusion scope for a set of compound
 * buttons. Checking one compound button that belongs to a group unchecks any
 * previously checked compound button within the same group. Intially, all of
 * the compound buttons are unchecked. While it is not possible to uncheck a
 * particular compound button, the group can be cleared to remove the checked
 * state. Basically, this class extends functionality of
 * {@link android.widget.RadioGroup} because it doesn't require that compound

 * buttons with other views. <br>
 * <br>
 * 
 * <b>IMPORTATNT! Follow these instruction when using this class:</b><br>
 * 1. Each direct child of this group must contain one compound button or be
 * compound button itself.<br>
 * 2. Do not set any "on click" or "on checked changed" listeners for the childs
 * of this group.

You need to do two things:

1. Use mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
2. Make your custom row view implement Checkable.

So I think that the better solution is to implement Checkable inside your inner LinearLayout: (thanks to daichan4649, from his link, https://gist.github.com/daichan4649/5245378, I took all the code pasted below)

CheckableLayout.java

package daichan4649.test;
 
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.Checkable;
import android.widget.LinearLayout;
 
public class CheckableLayout extends LinearLayout implements Checkable {
 
    private static final int[] CHECKED_STATE_SET = { android.R.attr.state_checked };
 
    public CheckableLayout(Context context) {
        super(context, null);
    }
 
    public CheckableLayout(Context context, AttributeSet attrs) {
        super(context, attrs, 0);
    }
 
    public CheckableLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
 
    private boolean checked;
 
    @Override
    public boolean isChecked() {
        return checked;
    }
 
    @Override
    public void setChecked(boolean checked) {
        if (this.checked != checked) {
            this.checked = checked;
            refreshDrawableState();
 
            for (int i = 0; i < getChildCount(); i++) {
                View child = getChildAt(i);
                if (child instanceof Checkable) {
                    ((Checkable) child).setChecked(checked);
                }
            }
        }
    }
 
    @Override
    public void toggle() {
        setChecked(!checked);
    }
 
    @Override
    protected int[] onCreateDrawableState(int extraSpace) {
        final int[] drawableState = super.onCreateDrawableState(extraSpace + 1);
        if (isChecked()) {
            mergeDrawableStates(drawableState, CHECKED_STATE_SET);
        }
        return drawableState;
    }
}

I've face the same problem as I want to place 4 different radio button in two different linearlayout and these layout will be the child of radio group. To achieve the desire behavior in RadioGroup I have overloaded the addView function

Here is the solution

public class AgentRadioGroup extends RadioGroup
{

    public AgentRadioGroup(Context context) {
        super(context);
    }

    public AgentRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onViewAdded(View child) {
        if( child instanceof ViewGroup)
        {
            ViewGroup viewGroup = (ViewGroup) child;
            for(int i=0; i<viewGroup.getChildCount(); i++)
            {
                View subChild = viewGroup.getChildAt(i);
                if( subChild instanceof ViewGroup )
                {
                    onViewAdded(subChild);
                }
                else
                {
                    if (subChild instanceof RadioButton) {
                        super.onViewAdded(subChild);
                    }
                }
            }
        }
        if (child instanceof RadioButton)
        {
            super.onViewAdded(child);
        }
    }
}

There is nothing stopping you from implementing that layout structure(RadioGroup is in fact a subclass of LinearLayout) but you shouldn't. First of all you create a structure 4 levels deep(using another layout structure you could optimize this) and second, if your RadioButtons are not direct children of a RadioGroup, the only one item selected in group will not work. This means that if you select a Radiobutton from that layout and then select another RadioButton you'll end up with two RadioButtons selected instead of the last selected one.

If you explain what you want to do in that layout maybe I can recommend you an alternative.

My $0.02 based on @infografnet and @lostdev (also thanks @Neromancer for the Compound Button suggestion!)

public class AdvRadioGroup {
    public interface OnButtonCheckedListener {
        void onButtonChecked(CompoundButton button);
    }

    private final List<CompoundButton> buttons;
    private final View.OnClickListener onClick = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setChecked((CompoundButton) v);
        }
    };

    private OnButtonCheckedListener listener;
    private CompoundButton lastChecked;


    public AdvRadioGroup(View view) {
        buttons = new ArrayList<>();
        parseView(view);
    }

    private void parseView(final View view) {
        if(view instanceof CompoundButton) {
            buttons.add((CompoundButton) view);
            view.setOnClickListener(onClick);
        } else if(view instanceof ViewGroup) {
            final ViewGroup group = (ViewGroup) view;
            for (int i = 0; i < group.getChildCount();i++) {
                parseView(group.getChildAt(i));
            }
        }
    }

    public List<CompoundButton> getButtons() { return buttons; }

    public CompoundButton getLastChecked() { return lastChecked; }

    public void setChecked(int index) { setChecked(buttons.get(index)); }

    public void setChecked(CompoundButton button) {
        if(button == lastChecked) return;

        for (CompoundButton btn : buttons) {
            btn.setChecked(false);
        }

        button.setChecked(true);

        lastChecked = button;

        if(listener != null) {
            listener.onButtonChecked(button);
        }
    }

    public void setOnButtonCheckedListener(OnButtonCheckedListener listener) { this.listener = listener; }
}

Usage (with included listener):

AdvRadioGroup group = new AdvRadioGroup(findViewById(R.id.YOUR_VIEW));
group.setOnButtonCheckedListener(new AdvRadioGroup.OnButtonCheckedListener() {
    @Override
    public void onButtonChecked(CompoundButton button) {
        // do fun stuff here!
    }
});

Bonus: You can get the last checked button, the list of entire buttons, and you can check any button by index with this!

As shown in answers, the solution is a simple custom hack. Here's my minimalistic version in Kotlin.

import android.widget.RadioButton

class SimpleRadioGroup(private val radioButtons: List<RadioButton>) {

    init {
        radioButtons.forEach {
            it.setOnClickListener { clickedButton ->
                radioButtons.forEach { it.isChecked = false }
                (clickedButton as RadioButton).isChecked = true
            }
        }
    }

    val checkedButton: RadioButton?
        get() = radioButtons.firstOrNull { it.isChecked }
}

then you just need to do something like that in your activity's onCreate or fragment's onViewCreated :

SimpleRadioGroup(listOf(radio_button_1, radio_button_2, radio_button_3))

    int currentCheckedRadioButton = 0;
    int[] myRadioButtons= new int[6];
    myRadioButtons[0] = R.id.first;
    myRadioButtons[1] = R.id.second;
    //..
    for (int radioButtonID : myRadioButtons) {
        findViewById(radioButtonID).setOnClickListener(
                    new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (currentCheckedRadioButton != 0)
                    ((RadioButton) findViewById(currentCheckedRadioButton)).setChecked(false);
                currentCheckedRadioButton = v.getId();

            }
        });
    }

There's already 20 answers, but dare I say I think I have the best one.

This uses view data binding, so the first thing you'll want to do is add this in your module's build.gradle.

android {
    dataBinding {
        enabled = true
    }
}

Then you can make a layout with your desired view hierarchy, for example:

fancy_radio_button.xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>
        <variable name="title" type="String"/>
        <variable name="description" type="String"/>
        <variable name="checked" type="boolean"/>
        <variable name="buttonId" type="int"/>
    </data>

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="match_parent">

        <!--  clickable=false since we implement the click listener on the whole view  -->
        <RadioButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:clickable="false"
            android:text="@{title}"
            android:checked="@{checked}"/>

        <TextView
            android:text="@{description}"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

        <View
            android:layout_width="match_parent"
            android:layout_height="24dp" />

    </LinearLayout>

</layout>

This can look however you want, just make sure to set android:clickable="false" on the RadioButton, and use the data binding variables where needed.

That layout gets handled by this class:

FancyRadioBroup.java

package com.example.app;

import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.RadioGroup;

import com.example.app.FancyRadioButtonBinding;

import java.util.ArrayList;

public class FancyRadioGroup extends RadioGroup implements View.OnClickListener {

    private final ArrayList<FancyRadioButtonBinding> radioButtons = new ArrayList<>();
    private OnSelectionChangedListener selectionChangedListener;

    public FancyRadioGroup(Context context) {
        super(context);
    }

    public FancyRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public void setOnSelectionChangedListener(OnSelectionChangedListener selectionChangedListener) {
        this.selectionChangedListener = selectionChangedListener;
    }

    public int addOption(String title, String description) {
        // inflate view and get binding
        FancyRadioButtonBinding buttonBinding = FancyRadioButtonBinding.inflate(LayoutInflater.from(getContext()), this, true);
        // set title and description
        buttonBinding.setTitle(title);
        buttonBinding.setDescription(description);
        // give the button an id (just use the index)
        buttonBinding.setButtonId(radioButtons.size());
        // set the root view's tag to the binding, so we can get the binding from the view
        View root = buttonBinding.getRoot();
        root.setTag(buttonBinding);
        // set click listener on the whole view, so we can click anywhere
        root.setOnClickListener(this);
        radioButtons.add(buttonBinding);
        // return button id to caller, so they know what was clicked
        return buttonBinding.getButtonId();
    }

    @Override
    public void onClick(View v) {
        for (FancyRadioButtonBinding binding : radioButtons) {
                binding.setChecked(v.getTag() == binding);
        }
        if (selectionChangedListener != null) {
            selectionChangedListener.onSelectionChanged(getSelected());
        }
    }

    public int getSelected() {
        for (FancyRadioButtonBinding binding : radioButtons) {
            if (binding.getChecked()) {
                return binding.getButtonId();
            }
        }
        return -1;
    }

    public interface OnSelectionChangedListener {
        void onSelectionChanged(int buttonId);
    }

}

To use, simply add the FancyRadioGroup to your view:

activity_foo.xml

<com.example.app.FancyRadioGroup android:id="@+id/radio_group"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

And then add your options:

FooActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    FancyRadioGroup radioGroup = findViewById(R.id.radio_group);
    radioGroup.addOption("The First One", "This option is recommended for users who like the number one.");
    radioGroup.addOption("The Second One", "For advanced users. Larger than one.");
    radioGroup.setOnSelectionChangedListener(this::doSomething);
}

private void doSomething(int id) {
    Toast.makeText(this, "selected: "+id, Toast.LENGTH_SHORT).show();
}

While this maybe an older topic, i would like to quickly share simple hacky code i wrote.. Its not for everyone and could do with some refinement as well..

The situation to use this code??
This code is for people who have a layout of the original question or similar, in my case it was as below. This personally was for a Dialog that i was using.

• LinLayout_Main
  • LinLayout_Row1
    • ImageView
    • RadioButton
  • LinLayout_Row2
    • ImageView
    • RadioButton
  • LinLayout_Row3
    • ImageView
    • RadioButton

What does the code do itself??
This code will enumerate ever Child of "LinLayout_Main" and for each child that is a "LinearLayout" it will then enumerate that View for any RadioButtons.

Simply it will look the parent "LinLayout_Main" and find any RadioButtons that are in any Child LinearLayouts.

MyMethod_ShowDialog
Will show a dialog with a XML layout file while also looking it to set the "setOnClickListener" for each RadioButton it finds

MyMethod_ClickRadio
Will loop each RadioButton the same way "MyMethod_ShowDialog" does but instead of setting the "setOnClickListener" it will instead "setChecked(false)" to clear each RadioButton and then as the last step will "setChecked(false)" to the RadioButton that called the click event.

public void MyMethod_ShowDialog(final double tmpLat, final double tmpLng) {
        final Dialog dialog = new Dialog(actMain);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.layout_dialogXML);

        final LinearLayout tmpLayMain = (LinearLayout)dialog.findViewById(R.id.LinLayout_Main);
        if (tmpLayMain!=null) {
            // Perform look for each child of main LinearLayout
            int iChildCount1 = tmpLayMain.getChildCount();
            for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){
                View tmpChild1 = tmpLayMain.getChildAt(iLoop1);
                if (tmpChild1 instanceof LinearLayout) {
                    // Perform look for each LinearLayout child of main LinearLayout
                    int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount();
                    for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){
                        View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2);
                        if (tmpChild2 instanceof RadioButton) {
                            ((RadioButton) tmpChild2).setOnClickListener(new RadioButton.OnClickListener() {
                                public void onClick(View v) {
                                    MyMethod_ClickRadio(v, dialog);
                                }
                            });
                        }
                    }
                }
            }

            Button dialogButton = (Button)dialog.findViewById(R.id.LinLayout_Save);
            dialogButton.setOnClickListener(new Button.OnClickListener() {
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });
        }
       dialog.show();
}


public void MyMethod_ClickRadio(View vRadio, final Dialog dDialog) {

        final LinearLayout tmpLayMain = (LinearLayout)dDialog.findViewById(R.id.LinLayout_Main);
        if (tmpLayMain!=null) {
            int iChildCount1 = tmpLayMain.getChildCount();
            for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){
                View tmpChild1 = tmpLayMain.getChildAt(iLoop1);
                if (tmpChild1 instanceof LinearLayout) {
                    int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount();
                    for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){
                        View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2);
                        if (tmpChild2 instanceof RadioButton) {
                            ((RadioButton) tmpChild2).setChecked(false);
                        }
                    }
                }
            }
        }

        ((RadioButton) vRadio).setChecked(true);
}

There maybe bugs, copied from project and renamed Voids/XML/ID

You can also run the same type of loop to find out which items are checked

This is a modified version of @Infografnet's solution. It's simple and easy to use.

RadioGroupHelper group = new RadioGroupHelper(this,R.id.radioButton1,R.id.radioButton2); group.radioButtons.get(0).performClick(); //programmatically

Just copy and paste

package com.qamar4p.farmer.ui.custom;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.view.View;
import android.widget.CompoundButton;
import android.widget.RadioButton;

public class RadioGroupHelper {

    public List<CompoundButton> radioButtons = new ArrayList<>();

    public RadioGroupHelper(RadioButton... radios) {
        super();
        for (RadioButton rb : radios) {
            add(rb);
        }
    }

    public RadioGroupHelper(Activity activity, int... radiosIDs) {
        this(activity.findViewById(android.R.id.content),radiosIDs);
    }

    public RadioGroupHelper(View rootView, int... radiosIDs) {
        super();
        for (int radioButtonID : radiosIDs) {
            add((RadioButton)rootView.findViewById(radioButtonID));
        }
    }

    private void add(CompoundButton button){
        this.radioButtons.add(button);
        button.setOnClickListener(onClickListener);
    }

    View.OnClickListener onClickListener = v -> {
        for (CompoundButton rb : radioButtons) {
            if(rb != v) rb.setChecked(false);
        }
    };
}

This is my solution on Kotlin for custom layout with RadioButton inside.

tipInfoContainerFirst.radioButton.isChecked = true

var prevSelected = tipInfoContainerFirst.radioButton
prevSelected.isSelected = true

listOf<RadioButton>(
    tipInfoContainerFirst.radioButton,
    tipInfoContainerSecond.radioButton,
    tipInfoContainerThird.radioButton,
    tipInfoContainerForth.radioButton,
    tipInfoContainerCustom.radioButton
).forEach {
    it.setOnClickListener { _it ->
	if(!it.isSelected) {
	    prevSelected.isChecked = false
	    prevSelected.isSelected = false
	    it.radioButton.isSelected = true
	    prevSelected = it.radioButton
	}
  }
}

I get into the same problem, I have to use Radio button for gender and all were with a picture and a text so I tried to resolve it using following way.

xml file:

<RadioGroup
       android:layout_marginTop="40dp"
       android:layout_marginEnd="23dp"
       android:id="@+id/rgGender"
       android:layout_width="match_parent"
       android:layout_below="@id/tvCustomer"
       android:orientation="horizontal"
       android:layout_height="wrap_content">

       <LinearLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:orientation="vertical"
           android:gravity="center_horizontal"
           android:layout_weight="1">
       <RadioButton
           android:id="@+id/rbMale"
           android:layout_width="80dp"
           android:layout_height="60dp"
           android:background="@drawable/male_radio_btn_selector"
           android:button="@null"
           style="@style/RadioButton.Roboto.20sp"/>

           <TextView
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:text="Male"
               style="@style/TextView.RobotoLight.TxtGrey.18sp"
               android:layout_margin="0dp"
               android:textSize="@dimen/txtsize_20sp"/>
       </LinearLayout>
       <LinearLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:orientation="vertical"
           android:gravity="center_horizontal"
           android:layout_weight="1">
       <RadioButton
           android:layout_weight="1"
           android:gravity="center"
           android:id="@+id/rbFemale"
           android:layout_width="80dp"
           android:layout_height="60dp"
           android:button="@null"
           android:background="@drawable/female_radio_btn_selector"
           style="@style/RadioButton.Roboto.20sp"
           android:textColor="@color/light_grey"/>
           <TextView
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:text="Female"
               android:layout_margin="0dp"
               style="@style/TextView.RobotoLight.TxtGrey.18sp"
               android:textSize="@dimen/txtsize_20sp"/>
       </LinearLayout>
       <LinearLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:orientation="vertical"
           android:gravity="center_horizontal"
           android:layout_weight="1">
       <RadioButton
           android:layout_weight="1"
           android:gravity="center"
           android:id="@+id/rbOthers"
           android:layout_width="80dp"
           android:layout_height="60dp"
           android:button="@null"
           android:background="@drawable/other_gender_radio_btn_selector"
           style="@style/RadioButton.Roboto.20sp"/>
          <TextView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="Other"
              android:layout_margin="0dp"
              style="@style/TextView.RobotoLight.TxtGrey.18sp"
              android:textSize="@dimen/txtsize_20sp"/>
      </LinearLayout>
   </RadioGroup>

In java file: I set setOnCheckedChangeListener on all 3 radio buttons and override method as mentioned below and its working fine for me.

@Override
    public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
   switch (compoundButton.getId()){
       case R.id.rbMale:
           if(rbMale.isChecked()){
               rbMale.setChecked(true);
               rbFemale.setChecked(false);
               rbOther.setChecked(false);
           }
           break;
       case R.id.rbFemale:
           if(rbFemale.isChecked()){
               rbMale.setChecked(false);
               rbFemale.setChecked(true);
               rbOther.setChecked(false);
           }
           break;
       case R.id.rbOthers:
           if(rbOther.isChecked()){
               rbMale.setChecked(false);
               rbFemale.setChecked(false);
               rbOther.setChecked(true);
           }
           break;

   }
    }

MixedCompoundButtonGroup do it for you!
