Problem inflating custom view for AlertDialog in DialogFragment

Android Android Alertdialog Android Fragments Android Inflate Layout Inflater

Android Problem Overview

I'm trying to create a DialogFragment using a custom view in an AlertDialog. This view must be inflated from xml. In my DialogFragment class I have:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new AlertDialog.Builder(getActivity())
        .setTitle("Title")
        .setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, null))
        .setPositiveButton(android.R.string.ok, this)
        .setNegativeButton(android.R.string.cancel, null)
        .create();
}

I have tried other inflation methods for .setView() such as:

.setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getView(), false))

and

.setView(getActivity().getLayoutInflater().inflate(R.layout.dialog, (ViewGroup) getTargetFragment().getView(), false))

After setting the target fragment in the fragment that is showing this dialog.

All of these attempts to inflate my custom view result in the following exception:

While if I try to use the DialogFragment's getLayoutInflator(Bundle) like this:

.setView(getLayoutInflater(savedInstanceState).inflate(R.layout.dialog, null))

I get a StackOverflowError.

Does anyone know how to inflate a custom view for an AlertDialog in a DialogFragment?

Solution 1 - Android

The first error line gives me the hint that this is related to how you are creating your dialog - not the dialog itself.

Are you creating the dialog automatically (which could mean this gets called before the views are all set up) or in response to a button click? I initially had problems with fragments due to instantiation order.

I used the same code to set the view as you have, and my result works. I cut out the other setup to make this look cleaner, but it works with or without it.

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    
    View view = getActivity().getLayoutInflater().inflate(R.layout.dialog_layout, null);
    builder.setView(view);

    return builder.create();
}

I'm surprised by these answers as none of them solve the problem.

A DialogFragment allows you to reuse the same UI for both a dialog and integrated in your app elsewhere as a fragment. Quite a useful feature. As per google's documentation, you can achieve this by overriding onCreateDialog and onCreateView. http://developer.android.com/reference/android/app/DialogFragment.html

There are three scenarios here:

Override onCreateDialog only - Works as a dialog but cannot be integrated elsewhere.
Override onCreateView only - Does not work as a dialog but can be integrated elsewhere.
Override both - Works as a dialog and can be integrated elsewhere.

Solution: The AlertDialog class is calling another class which calls requestFeature. To fix this.. Don't use the AlertDialog, instead use a plain Dialog or whatever super.onCreateDialog returns. This the solution that I have found works best.

Caveat: Other dialogs such as DatePickerDialog, ProgressDialog, TimePickerDialog all inherit from AlertDialog and will likely cause the same error.

Bottom Line: DialogFragment is good if you need to create very customized interface that needs to be used in several places. It doesn't appear to work to reuse existing android dialogs.

Avoid request feature crash and use same layout:

public class MyCombinedFragment extends DialogFragment
{
    private boolean isModal = false;

    public static MyCombinedFragment newInstance()
    {
        MyCombinedFragment frag = new MyCombinedFragment();
        frag.isModal = true; // WHEN FRAGMENT IS CALLED AS A DIALOG SET FLAG
        return frag;
    }

    public MyCombinedFragment()
    {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    {
        if(isModal) // AVOID REQUEST FEATURE CRASH
        {
        return super.onCreateView(inflater, container, savedInstanceState);
        }
        else
        {
        View view = inflater.inflate(R.layout.fragment_layout, container, false);
        setupUI(view);
        return view;
        }
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        AlertDialog.Builder alertDialogBuilder = null;
        alertDialogBuilder = new AlertDialog.Builder(getActivity());
        View view = getActivity().getLayoutInflater().inflate(R.layout.fragment_layout, null);
        alertDialogBuilder.setView(view);
        alertDialogBuilder.setTitle(“Modal Dialog“);
        alertDialogBuilder.setPositiveButton("Cancel", new DialogInterface.OnClickListener()
        {
            @Override
            public void onClick(DialogInterface dialog, int which)
            {
                dialog.dismiss();
            }
        });
        setupUI(view);
        return alertDialogBuilder.create();
    }
}

I had the same problem. In my case it was becasue Android Studio created a template onCreateView that re-inflated a new view instead of returning the view created in onCreateDialog. onCreateView is called after onCreateDialog, so the solution was to simply reurnt the fragments view.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    return this.getView();
}

Faced the same issue, and it took lot of time to get rid of the error. Finally passing resource ID to setView() method solved the problem. Add set view as below:

.setView(R.layout.dialog)

Solution 6 - Android

In your code where you call

 create().

Replace with

show().

Solution 7 - Android

I haven't inflated from XML but I have done dynamic view generation in a DialogFragment successfully:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
	m_editText = new EditText(getActivity());
	return new AlertDialog.Builder(getActivity())
			.setView(m_editText)
			.setPositiveButton(android.R.string.ok,null)
			.setNegativeButton(android.R.string.cancel, null);
			.create();
}

What you want to do instead is create your custom view in the onCreateView method like you normally would. If you want to do something like change the title of the dialog, you do that in onCreateView.

Here's an example to illustrate what I mean:

		@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
		getDialog().setTitle("hai");
		View v = inflater.inflate(R.layout.fragment_dialog, container, false);
		return v;
	}

Then you just call:

DialogFragment df = new MyDialogFragment();
df.show(..);

And voila, a dialog with your own custom view.

As i needed long time for solving the same problem (Pop up a simple Text Dialog) i decided to share my solution:

The layoutfile connectivity_dialog.xml contains a simple TextView with the message text:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:gravity="center"
              android:layout_gravity="center">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="20dp"
        android:layout_marginEnd="20dp"
        android:layout_marginTop="20dp"
        android:layout_marginBottom="20dp"
        android:text="Connectivity was lost"
        android:textSize="34sp"
        android:gravity="center"
        />
</RelativeLayout>

The Activity showing the "dialog" implements a inner class (as DialogFragment is a Fragment and not a Dialog; further info see https://stackoverflow.com/a/5607560/6355541). The Activity can activate and deactivate the DialogFragment via two functions. If you're using android.support.v4, you may want to change to getSupportFragmentManager():

public static class ConnDialogFragment extends DialogFragment {
    public static ConnDialogFragment newInstance() {
        ConnDialogFragment cdf = new ConnDialogFragment();
        cdf.setRetainInstance(true);
        cdf.setCancelable(false);
        return cdf;
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.connectivity, container, false);
    }
}

private void dismissConn() {
    DialogFragment df = (DialogFragment) getFragmentManager().findFragmentByTag("conn");
    if (df != null) df.dismiss();
}

private void showConn() {
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    Fragment prev = getFragmentManager().findFragmentByTag("conn");
    if (prev != null) ft.remove(prev);
    ft.addToBackStack(null);
    ConnDialogFragment cdf = ConnDialogFragment.newInstance();
    cdf.show(ft, "conn");
}
