Android How to adjust layout in Full Screen Mode when softkeyboard is visible

I have researched a lot to adjust the layout when softkeyboard is active and I have successfully implemented it but the problem comes when I use android:theme="@android:style/Theme.NoTitleBar.Fullscreen" this in my activity tag in manifest file.

For this I have used android:windowSoftInputMode="adjustPan|adjustResize|stateHidden" with different options but no luck.

After that I implemented FullScreen programmatically and tried various layout to work with FullScreen but all in vain.

I referred these links and have looked many posts here related to this issue:

http://davidwparker.com/2011/08/30/android-how-to-float-a-row-above-keyboard/

Here is xml code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/masterContainerView"
	android:layout_width="fill_parent" android:layout_height="fill_parent"
	android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"

			android:layout_toLeftOf="@+id/btn_save" android:text = "Cancel" />

	</RelativeLayout>
</RelativeLayout>

I want the bottom 2 buttons should go upward when the softkeyboard comes in picture.

Based on yghm's workaround, I coded up a convenience class that allows me to solve the problem with a one-liner (after adding the new class to my source code of course). The one-liner is:

     AndroidBug5497Workaround.assistActivity(this);

And the implementation class is:

public class AndroidBug5497Workaround {



// For more information, see https://issuetracker.google.com/issues/36911528
// To use this class, simply invoke assistActivity() on an Activity that already has its content view set.

public static void assistActivity (Activity activity) {
    new AndroidBug5497Workaround(activity);
}

private View mChildOfContent;
private int usableHeightPrevious;
private FrameLayout.LayoutParams frameLayoutParams;

private AndroidBug5497Workaround(Activity activity) {
    FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
    mChildOfContent = content.getChildAt(0);
    mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        public void onGlobalLayout() {
            possiblyResizeChildOfContent();
        }
    });
    frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
}

private void possiblyResizeChildOfContent() {
    int usableHeightNow = computeUsableHeight();
    if (usableHeightNow != usableHeightPrevious) {
        int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
        int heightDifference = usableHeightSansKeyboard - usableHeightNow;
        if (heightDifference > (usableHeightSansKeyboard/4)) {
            // keyboard probably just became visible
            frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
        } else {
            // keyboard probably just became hidden
            frameLayoutParams.height = usableHeightSansKeyboard;
        }
        mChildOfContent.requestLayout();
        usableHeightPrevious = usableHeightNow;
    }
}

private int computeUsableHeight() {
    Rect r = new Rect();
    mChildOfContent.getWindowVisibleDisplayFrame(r);
    return (r.bottom - r.top);
}




}

Hope this helps someone.

Since the answer has already been picked and problem known to be a bug, I thought I would add a "Possible Work Around".

You can toggle fullScreen mode when soft keyboard is shown. This allows the "adjustPan" to work correctly.

In other words, I still use @android:style/Theme.Black.NoTitleBar.Fullscreen as part of the application theme and stateVisible|adjustResize as part of the activity window soft input mode but to get them to work together I must toggle fullscreen mode before the keyboard comes up.

Use the following Code:

Turn Off full screen mode

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Turn On full screen mode

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

Note - inspiration came from: Hiding Title in a Fullscreen mode

I tried the solution from Joseph Johnson, but like others I ran into the gap-between-content-and-keyboard problem. The problem occurs because the soft input mode is always pan when using full-screen mode. This panning interferes with Joseph's solution when you activate an input field that would be hidden by the soft input.

When the soft input appears, the content is first panned based on its original height, and then resized by the layout requested by the Joseph's solution. The resizing and subsequent layout do not undo the panning, which results in the gap. The full order of events is:

1. Global layout listener
2. Panning
3. Layout of content (= actual resizing of content)

It is not possible to disable panning, but it is possible to force the pan offset to be 0 by changing the height of the content. This can be done in the listener, because it is run before panning takes place. Setting the content height to the available height results in a smooth user experience, i.e. no flickering.

I also made these changes. If any of these introduce issues, let me know:

• Switched determination of available height to use getWindowVisibleDisplayFrame. The Rect is cached to prevent a little bit of unneeded garbage.
• Allow the listener to be removed too. This is useful when you reuse an activity for different fragments having different full-screen requirements.
• Do not distinguish between keyboard shown or hidden, but always set the content height to the visible display frame height.

It has been tested on a Nexus 5, and emulators running API levels 16-24 with screen sizes ranging from tiny to big.

The code has been ported to Kotlin, but porting my changes back to Java is simple. Let me know if you need help:

class AndroidBug5497Workaround constructor(activity: Activity) {
    private val contentContainer = activity.findViewById(android.R.id.content) as ViewGroup
    private val rootView = contentContainer.getChildAt(0)
    private val rootViewLayout = rootView.layoutParams as FrameLayout.LayoutParams
    private val viewTreeObserver = rootView.viewTreeObserver
    private val listener = ViewTreeObserver.OnGlobalLayoutListener { possiblyResizeChildOfContent() }

    private val contentAreaOfWindowBounds = Rect()
    private var usableHeightPrevious = 0

    // I call this in "onResume()" of my fragment
    fun addListener() {
        viewTreeObserver.addOnGlobalLayoutListener(listener)
    }

    // I call this in "onPause()" of my fragment
    fun removeListener() {
        viewTreeObserver.removeOnGlobalLayoutListener(listener)
    }

    private fun possiblyResizeChildOfContent() {
        contentContainer.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds)
        val usableHeightNow = contentAreaOfWindowBounds.height()
        if (usableHeightNow != usableHeightPrevious) {
            rootViewLayout.height = usableHeightNow
            // Change the bounds of the root view to prevent gap between keyboard and content, and top of content positioned above top screen edge.
            rootView.layout(contentAreaOfWindowBounds.left, contentAreaOfWindowBounds.top, contentAreaOfWindowBounds.right, contentAreaOfWindowBounds.bottom)
            rootView.requestLayout()

            usableHeightPrevious = usableHeightNow
        }
    }
}

I just found a simple and reliable solution if you are using the system UI approach (https://developer.android.com/training/system-ui/immersive.html).

It works in the case when you are using View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN, e.g. if you are using CoordinatorLayout.

It won't work for WindowManager.LayoutParams.FLAG_FULLSCREEN (The one you can also set in theme with android:windowFullscreen), but you can achieve similar effect with SYSTEM_UI_FLAG_LAYOUT_STABLE (which "has the same visual effect" according to the docs) and this solution should work again.

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION /* If you want to hide navigation */
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE)

I've tested it on my device running Marshmallow.

The key is that soft keyboards are also one of the system windows (such as status bar and navigation bar), so the WindowInsets dispatched by system contains accurate and reliable information about it.

For the use case such as in DrawerLayout where we are trying to draw behind the status bar, We can create a layout that ignores only the top inset, and applies the bottom inset which accounts for the soft keyboard.

Here is my custom FrameLayout:

/**
 * Implements an effect similar to {@code android:fitsSystemWindows="true"} on Lollipop or higher,
 * except ignoring the top system window inset. {@code android:fitsSystemWindows="true"} does not
 * and should not be set on this layout.
 */
public class FitsSystemWindowsExceptTopFrameLayout extends FrameLayout {

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

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

    public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs,
                                                 int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
    public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs,
                                                 int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public WindowInsets onApplyWindowInsets(WindowInsets insets) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            setPadding(insets.getSystemWindowInsetLeft(), 0, insets.getSystemWindowInsetRight(),
                    insets.getSystemWindowInsetBottom());
            return insets.replaceSystemWindowInsets(0, insets.getSystemWindowInsetTop(), 0, 0);
        } else {
            return super.onApplyWindowInsets(insets);
        }
    }
}

And to use it:

<com.example.yourapplication.FitsSystemWindowsExceptTopFrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Your original layout here -->
</com.example.yourapplication.FitsSystemWindowsExceptTopFrameLayout>

This should theoretically work for any device without insane modification, much better than any hack that tries to take a random 1/3 or 1/4 of screen size as reference.

(It requires API 16+, but I'm using fullscreen only on Lollipop+ for drawing behind the status bar so it's the best solution in this case.)

Please note that android:windowSoftInputMode="adjustResize" does not work when WindowManager.LayoutParams.FLAG_FULLSCREENis set for an activity. You've got two options.

1. Either disable fullscreen mode for your activity. Activity is not re-sized in fullscreen mode. You can do this either in xml (by changing the theme of the activity) or in Java code. Add the following lines in your onCreate() method.

   getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);   
   getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);`
   

OR

2. Use an alternative way to achieve fullscreen mode. Add the following code in your onCreate() method.

   getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
   getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
   getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
   View decorView = getWindow().getDecorView();
   // Hide the status bar.
   int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
   decorView.setSystemUiVisibility(uiOptions);`
   

Please note that method-2 only works in Android 4.1 and above.

I had to face this problem too and had a work around which i checked on HTC one, galaxy s1, s2, s3, note and HTC sensation.

put a global layout listener on the root view of your layout

mRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
			public void onGlobalLayout() {
				checkHeightDifference();
			}
	});

and in there i checked the height difference and if the height difference of the screen is bigger then a third on the screen height then we can assume the keyboard is open. took it from [this answer][1].

private void checkHeightDifference(){
	// get screen frame rectangle 
	Rect r = new Rect();
	mRootView.getWindowVisibleDisplayFrame(r);
	// get screen height
	int screenHeight = mRootView.getRootView().getHeight();
	// calculate the height difference
	int heightDifference = screenHeight - (r.bottom - r.top);
	
	// if height difference is different then the last height difference and
	// is bigger then a third of the screen we can assume the keyboard is open
	if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
		// keyboard visiblevisible
		// get root view layout params
		FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
		// set the root view height to screen height minus the height difference
		lp.height = screenHeight - heightDifference;
		// call request layout so the changes will take affect
		.requestLayout();
		// save the height difference so we will run this code only when a change occurs.
		mLastHeightDifferece = heightDifference;
	} else if (heightDifference != mLastHeightDifferece) {
		// keyboard hidden
		PFLog.d("[ChatroomActivity] checkHeightDifference keyboard hidden");
		// get root view layout params and reset all the changes we have made when the keyboard opened.
		FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
		lp.height = screenHeight;
		// call request layout so the changes will take affect
		mRootView.requestLayout();
		// save the height difference so we will run this code only when a change occurs.
		mLastHeightDifferece = heightDifference;
	}
}

this is probably not bullet proof and maybe on some devices it will not work but it worked for me and hope it will help you too. [1]: https://stackoverflow.com/a/14149577/2424403

Add android:fitsSystemWindows="true" to the layout, and this layout will resize.

I implemented Joseph Johnson solution and it worked well, I noticed after using this solution sometimes the drawer on the application will not close properly. I added a functionality to remove the listener removeOnGlobalLayoutListener when the user closes the fragment where are edittexts located.

    //when the application uses full screen theme and the keyboard is shown the content not scrollable! 
//with this util it will be scrollable once again

uses the class where is my edittexts located

@Override

}

@Override
public void onStop()
{
	super.onStop();
	AndroidBug5497Workaround.getInstance(getActivity()).removeListener();
}

I'm currently using this approach and it works like a charm. The trick is we get keyboard height from different methods on 21 above and below and then use it as the bottom padding of our root view in our activity. I assumed your layout does not need a top padding (goes below status bar) but in case you do, inform me to update my answer.

MainActivity.java

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

                    v.setPadding(0, 0, 0, insets.getSystemWindowInsetBottom());
                    return insets;
                }
            });
        } else {
            View decorView = getWindow().getDecorView();
            final View contentView = mainLayout;
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    Rect r = new Rect();
                    //r will be populated with the coordinates of your view that area still visible.
                    decorView.getWindowVisibleDisplayFrame(r);

                    //get screen height and calculate the difference with the useable area from the r
                    int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
                    int diff = height - r.bottom;

                    //if it could be a keyboard add the padding to the view
                    if (diff != 0) {
                        // if the use-able screen height differs from the total screen height we assume that it shows a keyboard now
                        //check if the padding is 0 (if yes set the padding for the keyboard)
                        if (contentView.getPaddingBottom() != diff) {
                            //set the padding of the contentView for the keyboard
                            contentView.setPadding(0, 0, 0, diff);
                        }
                    } else {
                        //check if the padding is != 0 (if yes reset the padding)
                        if (contentView.getPaddingBottom() != 0) {
                            //reset the padding of the contentView
                            contentView.setPadding(0, 0, 0, 0);
                        }
                    }
                }
            });
        }
    }
...
}

Don't forget to address your root view with an id:

activity_main.xml

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

Hope it helps someone.

To get it to work with FullScreen:

Use the ionic keyboard plugin. This allows you to listen for when the keyboard appears and disappears.

OnDeviceReady add these event listeners:

// Allow Screen to Move Up when Keyboard is Present
window.addEventListener('native.keyboardshow', onKeyboardShow);
// Reset Screen after Keyboard hides
window.addEventListener('native.keyboardhide', onKeyboardHide);

The Logic:

function onKeyboardShow(e) {
    // Get Focused Element
    var thisElement = $(':focus');
    // Get input size
    var i = thisElement.height();
    // Get Window Height
    var h = $(window).height()
    // Get Keyboard Height
    var kH = e.keyboardHeight
    // Get Focused Element Top Offset
    var eH = thisElement.offset().top;
    // Top of Input should still be visible (30 = Fixed Header)
    var vS = h - kH;
    i = i > vS ? (vS - 30) : i;
    // Get Difference
    var diff = (vS - eH - i);
    if (diff < 0) {
        var parent = $('.myOuter-xs.myOuter-md');
        // Add Padding
        var marginTop = parseInt(parent.css('marginTop')) + diff - 25;
        parent.css('marginTop', marginTop + 'px');
    }
}

function onKeyboardHide(e) {
  // Remove All Style Attributes from Parent Div
  $('.myOuter-xs.myOuter-md').removeAttr('style');
}

Basically if they difference is minus then that is the amount of pixels that the keyboard is covering of your input. So if you adjust your parent div by this that should counteract it.

Adding timeouts to the logic say 300ms should also optimise performance (as this will allow keyboard time to appear.

I tried Joseph Johnson's class, and it worked, but didn't quite meet my needs. Rather than emulating android:windowSoftInputMode="adjustResize", I needed to emulate android:windowSoftInputMode="adjustPan".

I am using this for a full screen webview. To pan the content view to the correct position, I need to use a javascript interface which provides details on the position of the page element which has focus and thus is receiving the keyboard input. I have omitted those details, but provided my rewrite of Joseph Johnson's class. It will provide a very solid base for you to implement a custom pan vs. his resize.

//-------------------------------------------------------
// ActivityPanner Class
//
// Convenience class to handle Activity attributes bug.
// Use this class instead of windowSoftInputMode="adjustPan".
//
// To implement, call enable() and pass a reference
// to an Activity which already has its content view set.
// Example:
//      setContentView( R.layout.someview );
//      ActivityPanner.enable( this );
//-------------------------------------------------------
//
// Notes:
//
// The standard method for handling screen panning
// when the virtual keyboard appears is to set an activity
// attribute in the manifest.
// Example:
// <activity
//      ...
//      android:windowSoftInputMode="adjustPan"
//      ... >
// Unfortunately, this is ignored when using the fullscreen attribute:
//      android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

}

1. Create KeyboardHeightHelper:

   public class KeyboardHeightHelper {

    private final View decorView;
    private int lastKeyboardHeight = -1;
   
    public KeyboardHeightHelper(Activity activity, View activityRootView, OnKeyboardHeightChangeListener listener) {
        this.decorView = activity.getWindow().getDecorView();
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
            int keyboardHeight = getKeyboardHeight();
            if (lastKeyboardHeight != keyboardHeight) {
                lastKeyboardHeight = keyboardHeight;
                listener.onKeyboardHeightChange(keyboardHeight);
            }
        });
    }
   
    private int getKeyboardHeight() {
        Rect rect = new Rect();
        decorView.getWindowVisibleDisplayFrame(rect);
        return decorView.getHeight() - rect.bottom;
    }
   
    public interface OnKeyboardHeightChangeListener {
        void onKeyboardHeightChange(int keyboardHeight);
    }
   

   }

2. Let your activity be full screen:

activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

3. Listen for keyboard height changes and add bottom padding for your view:

   View rootView = activity.findViewById(R.id.root); // your root view or any other you want to resize KeyboardHeightHelper effectiveHeightHelper = new KeyboardHeightHelper( activity, rootView, keyboardHeight -> rootView.setPadding(0, 0, 0, keyboardHeight));

So, each time keyboard will appear on the screen - bottom padding for your view will change, and content will be rearranged.

Just keep as android:windowSoftInputMode="adjustResize". Because it is given to keep only one out of "adjustResize" and "adjustPan"(The window adjustment mode is specified with either adjustResize or adjustPan. It is highly recommended that you always specify one or the other). You can find it out here: http://developer.android.com/resources/articles/on-screen-inputs.html

It works perfectly for me.

Indeed the soft keyboard appearance doesn't seem to affect the Activity in any way no matter what windowSoftInputMode I select in the FullScreen mode.

Though I couldn't find much documentation on this property, I think that the FullScreen mode was designed for gaming application which do not require much use of the soft keyboard. If yours is an Activity which requires user interaction through soft keyboard, please reconsider using a non-FullScreen theme. You could turn off the TitleBar using a NoTitleBar theme. Why would you want to hide the notification bar?

only use android:windowSoftInputMode="adjustResize|stateHidden as you use AdjustPan then it disable the resizing property

> I used Joseph Johnson created AndroidBug5497Workaround class but getting black space between softkeyboard and the view. I referred this link Greg Ennis. After doing some changes to the above this is my final working code.

old idea

Create a static value of the containers height before opening the keyboard Set the container height based on usableHeightSansKeyboard - heightDifference when the keyboard opens and set it back to the saved value when it closes

if (heightDifference > (usableHeightSansKeyboard / 4)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
                int mStatusHeight = getStatusBarHeight();
                frameLayoutParams.topMargin = mStatusHeight;
                ((MainActivity)activity).setMyMainHeight(usableHeightSansKeyboard - heightDifference);

                if(BuildConfig.DEBUG){
                    Log.v("aBug5497", "keyboard probably just became visible");
                }
            } else {
                // keyboard probably just became hidden
                if(usableHeightPrevious != 0) {
                    frameLayoutParams.height = usableHeightSansKeyboard;
                    ((MainActivity)activity).setMyMainHeight();    
                }
                frameLayoutParams.topMargin = 0;

                if(BuildConfig.DEBUG){
                    Log.v("aBug5497", "keyboard probably just became hidden");
                }
            }

Methods in MainActivity

public void setMyMainHeight(final int myMainHeight) {

    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            ConstraintLayout.LayoutParams rLparams =  (ConstraintLayout.LayoutParams) myContainer.getLayoutParams();
            rLparams.height = myMainHeight;

            myContainer.setLayoutParams(rLparams);
        }

    });

}

int mainHeight = 0;
public void setMyMainHeight() {

    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            ConstraintLayout.LayoutParams rLparams =  (ConstraintLayout.LayoutParams) myContainer.getLayoutParams();
            rLparams.height = mainHeight;

            myContainer.setLayoutParams(rLparams);
        }

    });

}

Example Container XML

<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
        <android.support.constraint.ConstraintLayout
            android:id="@+id/my_container"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            app:layout_constraintHeight_percent=".8">

similarly margins can be added if needed...

Another consideration is use padding an example of this can be found at:

https://github.com/mikepenz/MaterialDrawer/issues/95#issuecomment-80519589

You want the bottom bar to stick to the bottom of the view, but when the keyboard is displayed, they should move up to be placed above the keyboard, right?

You can try this code snippet:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    ...>

    <RelativeLayout
	    android:id="@+id/RelativeLayoutTopBar"
    ...>
    </RelativeLayout>

    <LinearLayout
	    android:id="@+id/LinearLayoutBottomBar"
        android:layout_alignParentBottom = true
	    ...>
    </LinearLayout>

    <LinearLayout
	android:layout_width="fill_parent"
	android:layout_height="390dp"
	android:orientation="vertical" 
	android:layout_above="@+id/LinearLayoutBottomBar"
	android:layout_below="@+id/RelativeLayoutTopBar"> 
	
    <ScrollView 
      	android:layout_width="fill_parent" 
      	android:layout_height="wrap_content"
      	android:layout_marginTop="10dp"
      	android:layout_marginBottom="10dp"
      	android:id="@+id/ScrollViewBackground">

            ...

        </ScrollView>
     </LinearLayout>
  </RelativeLayout>

The BottomBar will stick to the bottom of the view and the LinearLayout containing the ScrollView will take what's left of the view after the top/bottom bar and the keyboard are displayed. Let me know if it works for you as well.

Thank you Joseph for your answer. However, in the method possiblyResizeChildOfContent(), the portion

else {
            // keyboard probably just became hidden
            frameLayoutParams.height = usableHeightSansKeyboard;
        }

was not working for me, as the lower portion of view became hidden. So I had to take a global variable restoreHeight, and in the constructor, I inserted the last line

restoreHeight = frameLayoutParams.height;

and then I replaced the former mentioned part with

else {
            // keyboard probably just became hidden
            frameLayoutParams.height = restoreHeight;
        }

But I have no idea why your code didn't work for me. It would be of great help, if someone can shed light on this.

I was only using full screen mode to hide the status bar. However, I want the app to resize when keyboard is shown. All of the other solutions (likely due to age of post) were complicated or not possible for my use (want to avoid change Java code for sack of PhoneGap Build).

Instead of using Full screen, I modified my configure for Android to be non-fullscreen:

		    <preference name="fullscreen" value="false" />

And added the cordova-plugin-statusbar, via command line:

cordova plugin add cordova-plugin-statusbar

When app has loaded, I simple call a method on the plugin to hide itself, like:

    if (window.cordova && window.cordova.platformId == 'android' && window.StatusBar)
        window.StatusBar.hide();

This works like a charm. Only real downside is that the status bar is breifly visible while the app loads. For my needs, that wasn't an issue.

I have tried out all the possible answers from stackOverflow, finally i solved after a week Long search . I have used the coordinate layout and i changed this with linearLayout and my problem is fixed. I dont know possibly the coordinate layout has bugs or anything my mistake.

I tried many solutions include Joseph Johnson's and Johan Stuyts's. But as a result I got a white space between content and keyboard on some devices (like Lenovo s820) in all cases. So I made some changes to their codes and finally got working solution.

My idea based on adding margin to top of content when keyboard is showing.

contentContainer.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds);
    int usableHeightNow = contentAreaOfWindowBounds.height();

    if (usableHeightNow != usableHeightPrevious) {

        int difference = usableHeightNow - usableHeightPrevious;

        if (difference < 0 && difference < -150) {
            keyboardShowed = true;
            rootViewLayout.topMargin -= difference + 30;
            rootViewLayout.bottomMargin += 30;
        }
        else if (difference < 0 && difference > -150){
            rootViewLayout.topMargin -= difference + 30;
        }
        else if (difference > 0 && difference > 150) {
            keyboardShowed = false;
            rootViewLayout.topMargin = 0;
            rootViewLayout.bottomMargin = 0;
        }
        
        rootView.requestLayout();

        Log.e("Bug Workaround", "Difference: " + difference);

        usableHeightPrevious = usableHeightNow;
}

As you can see, I add 30 px to difference because there is a small white space between top of the screen and content zone with margin. And I dont know whence it appears so I decided just make margins smaller and now it works exactly how I needed.

Today not working adjustResize on full screen issue is actual for android sdk.

From answers i found:
the solution - but solution has this showing on picture issue :

Than i found the solution and remove the one unnecessary action:

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

So, see my fixed solution code on Kotlin:

class AndroidBug5497Workaround constructor(val activity: Activity) {

    private val content = activity.findViewById<View>(android.R.id.content) as FrameLayout

    private val mChildOfContent = content.getChildAt(0)
    private var usableHeightPrevious: Int = 0
    private val contentContainer = activity.findViewById(android.R.id.content) as ViewGroup
    private val rootView = contentContainer.getChildAt(0)
    private val rootViewLayout = rootView.layoutParams as FrameLayout.LayoutParams

    private val listener = {
        possiblyResizeChildOfContent()
    }

    fun addListener() {
        mChildOfContent.apply {
            viewTreeObserver.addOnGlobalLayoutListener(listener)

        }
    }

    fun removeListener() {
        mChildOfContent.apply {
            viewTreeObserver.removeOnGlobalLayoutListener(listener)
        }
    }

    private fun possiblyResizeChildOfContent() {
        val contentAreaOfWindowBounds = Rect()
        mChildOfContent.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds)
        val usableHeightNow = contentAreaOfWindowBounds.height()

        if (usableHeightNow != usableHeightPrevious) {
            rootViewLayout.height = usableHeightNow
            rootView.layout(contentAreaOfWindowBounds.left,
                    contentAreaOfWindowBounds.top, contentAreaOfWindowBounds.right, contentAreaOfWindowBounds.bottom);
            mChildOfContent.requestLayout()
            usableHeightPrevious = usableHeightNow
        }
    }
}

                        layoutParams.height=height;
                        rootLayout.setLayoutParams(layoutParams);
                    }else{
                        height=ViewGroup.LayoutParams.MATCH_PARENT;
                        if( height!=layoutParams.height) {
                            layoutParams.height = height;
                            rootLayout.setLayoutParams(layoutParams);
                        }
                    }
                }
            });
        }

Using android:windowSoftInputMode="adjustResize|stateHidden might not work in all cases and also android:fitsSystemWindows="true doesn't help when you use SYSTEM_UI_FLAG_FULLSCREEN tags. To make view/window/webview adjustable when Keyboard visible do the following things.

• Use RelativeLayout as root layout.
• Declare the above method resizeWindowOnKeyboardVisible() in an activity & call it after setContentView() in onCreate() method.

It works in Android 11 (API 30) also.

There is another way, without creating own helper classes or functions that calculate the height of the screen. Instead use ViewCompat.setOnApplyWindowInsetsListener. With the listener you can check if the keyboard is open and set the bottom padding based on the keyboard height.

// the root view of your webview, e.g FrameLayout or LinearLayout
    rootView = view.findViewById(R.id.whatever);
    
    ViewCompat.setOnApplyWindowInsetsListener(rootView, (webView, insets) -> {
        
        // checks if keyboard is visible, the Type.ime() stands for Input Method
        boolean isKeyboardVisible = insets.isVisible(WindowInsetsCompat.Type.ime());
        
        // get the keyboard height and use the height as bottom padding for your view
        int bottomKeyboardPadding = insets.getInsets(WindowInsetsCompat.Type.ime()).bottom;

        
        if (isKeyboardVisible) { webView.setPadding(0, 0, 0, bottomKeyboardPadding); }
        else { webView.setPadding(0, 0, 0, 0); }

        return insets;
    });

In my case, this issue started happening once I added Crosswalk to my Cordova application. My app is not used in fullscreen and android:windowSoftInputMode="adjustPan".

I already had the ionic keyboard plugin in the application, so detecting if the keyboard was up or down was easy thanks to it:

// Listen for events to when the keyboard is opened and closed
window.addEventListener("native.keyboardshow", keyboardUp, false);
window.addEventListener('native.keyboardhide', keyboardDown, false);

function keyboardUp()
{
	$('html').addClass('keyboardUp');
}

function keyboardDown()
{
	$('html').removeClass('keyboardUp');
}

I tried all of the fixes above but the simple line that ended up doing it for me was this bit of css:

&.keyboardUp {
		overflow-y: scroll;
}

Hope this saves you the few days I spent on this. :)

Don't use:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

because works bad. Instead of that, use:

fun setFullScreen(fullScreen: Boolean) {
        val decorView = getWindow().getDecorView()
        val uiOptions : Int
        if(fullScreen){
            uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN // this hide statusBar
            toolbar.visibility = View.GONE // if you use toolbar
            tabs.visibility = View.GONE // if you use tabLayout
        } else {
            uiOptions = View.SYSTEM_UI_FLAG_VISIBLE // this show statusBar
            toolbar.visibility = View.VISIBLE
            tabs.visibility = View.VISIBLE
        }
        decorView.setSystemUiVisibility(uiOptions)
    }
