A FrameLayout subclass that dispatches WindowInsets to its children instead of adjusting its padding. Useful for Fragment containers.

WindowInsetsFrameLayout.java

package com.pkmmte.widget;

import android.annotation.TargetApi;
import android.content.Context;
import android.os.Build;
import android.util.AttributeSet;
import android.view.WindowInsets;
import android.widget.FrameLayout;

public class WindowInsetsFrameLayout extends FrameLayout {
	public WindowInsetsFrameLayout(Context context) {
		super(context);
	}

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

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

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

	@TargetApi(Build.VERSION_CODES.KITKAT_WATCH)
	@Override
	public WindowInsets onApplyWindowInsets(WindowInsets insets) {
		int childCount = getChildCount();
		for (int index = 0; index < childCount; index++)
			getChildAt(index).dispatchApplyWindowInsets(insets);

		return insets;
	}
}

amazing, thank you!

Hi, any example how to use it? Because simply replacing my old FrameLayout with this class doesn't seem to work for me.

@sevar83 I don't really have any samples to show. As long as your parent layouts and this layout all have fitsSystemWindows="true", it should work fine.

thanks @Pkmmte works like a champ.. :)

what about preloli? ViewCompat?

Thanks for sharing! It did not fix my specific problem, but for whoever might be interested, this is the Kotlin version:

class WindowInsetsFrameLayout @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0, defStyleRes: Int = 0) : FrameLayout(context, attrs, defStyleAttr, defStyleRes) {
    @TargetApi(Build.VERSION_CODES.KITKAT_WATCH)
    override fun onApplyWindowInsets(insets: WindowInsets): WindowInsets {
        val childCount = getChildCount()
        for (index in 0 until childCount)
            getChildAt(index).dispatchApplyWindowInsets(insets)

        return insets
    }
}
