android – windowSoftInputMode="adjustResize" not working with translucent action/navbar

Posted by: admin March 11, 2020 Leave a comment

Questions:

I have problems with the translucent actionbar/navbar in the new Android KitKat (4.4) and the windowSoftInputMode="adjustResize".

Normaly changing the InputMode to adjustResize, the app should resize itself when keyboard is shown… but here it won’t! If I delete the lines for the transparent effect, the resize is working.

So if the keyboard is visible, my ListView is under it and I can’t access the last few items. (Only by hiding the keyboard manually)

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="XYZ"
android:versionCode="23"
android:versionName="0.1" >

Anyone ideas for fixing this?

How to&Answers:

You are missing the following property:

android:fitsSystemWindows="true"

in the root RelativeLayout of the fragment .xml layout.

Update:

Last year there was an interesting talk by Chris Bane that explains in good detail how this works:

Answer:

There’s a related bug report here. I’ve found a workaround that, from limited testing, seems to do the trick with no repercussions. Add a custom implementation of your root ViewGroup (I almost always am using FrameLayout, so this is what I’ve tested with) with the logic below. Then, use this custom layout in place of your root layout, and ensure you set android:fitsSystemWindows="true". You can then just call getInsets() any time after layout (e.g. add an OnPreDrawListener) to adjust the rest of your layout to account for the system insets, if desired.

import android.graphics.Rect;
import android.os.Build;
import android.util.AttributeSet;
import android.widget.FrameLayout;

public final class CustomInsetsFrameLayout extends FrameLayout {
    private int[] mInsets = new int[4];

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

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

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

    public final int[] getInsets() {
        return mInsets;
    }

    @Override
    protected final boolean fitSystemWindows(@NotNull Rect insets) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            // Intentionally do not modify the bottom inset. For some reason, 
            // if the bottom inset is modified, window resizing stops working.
            // TODO: Figure out why.

            mInsets[0] = insets.left;
            mInsets[1] = insets.top;
            mInsets[2] = insets.right;

            insets.left = 0;
            insets.top = 0;
            insets.right = 0;
        }

        return super.fitSystemWindows(insets);
    }
}

Since fitSystemWindows was deprecated, please refer to the answer below to complete the workaround.

Answer:

@kcoppock answer is really helpful, but fitSystemWindows was deprecated in API level 20

So since API 20 (KITKAT_WATCH) you should override onApplyWindowInsets

@Override
public final WindowInsets onApplyWindowInsets(WindowInsets insets) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
        return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,
                insets.getSystemWindowInsetBottom()));
    } else {
        return insets;
    }
}

Answer:

This worked for me to have translucent status bar and adjustResize in fragment:

  1. Make a custom RelativeLayout as @Victor91 and @kcoppock said.

  2. Use CustomRelativeLayout as parent layout for your fragment.

  3. Declare theme with android:windowTranslucentStatus = true

  4. The container Activity must be declared in Manifest with
    android:windowSoftInputMode=”adjustResize” and use the declared
    theme

  5. Please Use fitsSystemWindows on fragment root layout!

    public class CustomRelativeLayout extends RelativeLayout {
    
        private int[] mInsets = new int[4];
    
        public CustomRelativeLayout(Context context) {
            super(context);
        }
    
        public CustomRelativeLayout(Context context, AttributeSet attrs) {
            super(context, attrs);
        }
    
        public CustomRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr) {
            super(context, attrs, defStyleAttr);
        }
    
        public CustomRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
            super(context, attrs, defStyleAttr, defStyleRes);
        }
    
        @Override
        public final WindowInsets onApplyWindowInsets(WindowInsets insets) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
                mInsets[0] = insets.getSystemWindowInsetLeft();
                mInsets[1] = insets.getSystemWindowInsetTop();
                mInsets[2] = insets.getSystemWindowInsetRight();
                return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,
                        insets.getSystemWindowInsetBottom()));
            } else {
                return insets;
            }
        }
    }
    

Then in xml,

<com.blah.blah.CustomRelativeLayout 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:fitsSystemWindows="true">
</com.blah.blah.CustomRelativeLayout>

Answer:

If you want to customize the insets and you are targeting API level >=21 you can accomplish this without having to create a custom view group. By just setting fitsSystemWindows padding will be applied to your container view by default, which you may not want.

The version checks are built into this method and only devices >= 21 will execute the code inside the lambda. Kotlin example:

ViewCompat.setOnApplyWindowInsetsListener(container) { view, insets ->
  insets.replaceSystemWindowInsets(0, 0, 0, insets.systemWindowInsetBottom).apply {
    ViewCompat.onApplyWindowInsets(view, this)
  }
}

Make sure your layout still sets the fitsSystemWindows flag otherwise the window insets listener will not be called.

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    />

Answer:

I had the same problem,
My Activity had a ScrollView as root view and with translucent statusbar activated it didn’t resize correctly when keyboard showed… and conseguently the screen didn’t scrolled hiding the input views.

Solution:
Moved everything (layout and activity logic) inside a new Fragment.
Then changed the Activity to only include this Fragment. Now everything works as expected!

This is the layout of the activity:

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

    android:id="@+id/contentView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true" />

Answer:

Based on Joseph Johnson’s workaround in Android How to adjust layout in Full Screen Mode when softkeyboard is visible

call this in onCreate() after setContentView() in your activity.

AndroidBug5497Workaround.assistActivity(this);

a litte different from original replace return (r.bottom - r.top); with return r.bottom; in computeUsableHeight()

for some reason, i must set my activity fitsSystemWindows attribute to false.

this workaround saved me. it’s works well for me. hope can help you.

the implementation class is:

public class AndroidBug5497Workaround {

// For more information, see https://code.google.com/p/android/issues/detail?id=5497
// 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;
}

}

Answer:

It shouldn’t work with the translucent status bar; that setting forces the window into fullscreen mode which does not work with adjustResize.

You can either use adjustPan or use the fitsSystemWindows properties. I would suggest reading about the feature though, it has significant side effects:

Answer:

AndroidBug5497Workaround.java take care memory leak. need below code

getViewTreeObserver().removeOnGlobalLayoutListener(listener);

My sample using RxJava that automatically call removeOnGlobalLayoutListener() when onPause() in Activity’s lifecycle

public class MyActivity extends RxAppCompatActivity {
    // ...

protected void onStart(){
    super.onStart();

        TRSoftKeyboardVisibility
            .changes(this) // activity
            .compose(this.<TRSoftKeyboardVisibility.ChangeEvent>bindUntilEvent(ActivityEvent.PAUSE))
            .subscribe(keyboardEvent -> {
                FrameLayout content = (FrameLayout) findViewById(android.R.id.content);
                View firstChildView = content.getChildAt(0);
                firstChildView.getLayoutParams().height = keyboardEvent.viewHeight();
                firstChildView.requestLayout();

                // keyboardEvent.isVisible      = keyboard visible or not
                // keyboardEvent.keyboardHeight = keyboard height
                // keyboardEvent.viewHeight     = fullWindowHeight - keyboardHeight
            });
   //...

Answer:

I had like a problem.

I set windowDrawsSystemBarBackgrounds to ‘true’ and my app should show under status bar.

It’s my activity theme.

<item name="android:windowTranslucentStatus" tools:targetApi="KITKAT">false</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>

and I got help from jianshu’s blog.
you can read code but text like me.
I add few code more.

public final class ZeroInsetsFrameLayout extends FrameLayout {
    private int[] mInsets = new int[4];

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

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

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

    public final int[] getInsets() {
        return mInsets;
    }

    @Override
    public WindowInsets computeSystemWindowInsets(WindowInsets in, Rect outLocalInsets) {
        outLocalInsets.left = 0;
        outLocalInsets.top = 0;
        outLocalInsets.right = 0;

        return super.computeSystemWindowInsets(in, outLocalInsets);
    }

    @Override
    protected final boolean fitSystemWindows(@NonNull Rect insets) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            // Intentionally do not modify the bottom inset. For some reason,
            // if the bottom inset is modified, window resizing stops working.
            // TODO: Figure out why.

            mInsets[0] = insets.left;
            mInsets[1] = insets.top;
            mInsets[2] = insets.right;

            insets.left = 0;
            insets.top = 0;
            insets.right = 0;
        }

        return super.fitSystemWindows(insets);
    }
}

This is my fragment layout.

<com.dhna.widget.ZeroInsetsFrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:background="@color/white">

    <!-- your xml code -->

</ZeroInsetsFrameLayout>

I want it to be helpful to you.
good luck!

Answer:

  • After I had researched on all forum. thoese ways can not help find point out. Lucky when i tried doing this way. It helps me resolved problem

XML

<RelativeLayout 
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:fitsSystemWindows="true">
       <!-- Your xml -->
    </RelativeLayout>

Activity

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView("Your Activity");
   setAdjustScreen();

}

Created Func

protected void setAdjustScreen(){
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
        /*android:windowSoftInputMode="adjustPan|adjustResize"*/
}

Finally adding some lines to your mainifest

 <activity
     android:name="Your Activity"
     android:windowSoftInputMode="adjustPan|adjustResize"
     android:screenOrientation="portrait"></activity>

Answer:

I had the same problem. I have solved using coordinatorlayout

activity.main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    android:layout_height="match_parent" android:layout_width="match_parent"

Answer:

Add this first at your root layout.

android:fitsSystemWindows="true"

When you use this approach, it becomes your responsibility to ensure that critical parts of your app’s UI (for example, the built-in controls in a Maps application) don’t end up getting covered by system bars. This could make your app unusable. In most cases you can handle this by adding the android:fitsSystemWindows attribute to your XML layout file, set to true. This adjusts the padding of the parent ViewGroup to leave space for the system windows. This is sufficient for most applications.

In some cases, however, you may need to modify the default padding to get the desired layout for your app. To directly manipulate how your content lays out relative to the system bars (which occupy a space known as the window’s “content insets”), override fitSystemWindows(Rect insets). The fitSystemWindows() method is called by the view hierarchy when the content insets for a window have changed, to allow the window to adjust its content accordingly. By overriding this method you can handle the insets (and hence your app’s layout) however you want.

Answer:

The best practice allows user scroll content when the keyboard is shown.
So to add this functionality you need put your root layout inside the ScrollView and use windowSoftInputMode="adjustResize" activity method.

But if you want to use this functionality with <item name="android:windowTranslucentStatus">true</item>
flag on Android 5 content won’t be scrollable and will overlaps with keyboard.
