Prevent BottomSheetDialogFragment covering navigation bar

Question

I\'m using really naive code to show a bottom sheet dialog fragment:

class LogoutBottomSheetFragment : BottomSheetDialogFragment() {

    override fun onCrea         


        

Answer 1

I had the same problem. After looking into sources I found a workaround (a little bit hacky, but I found no alternatives).

public class YourDialog extends BottomSheetDialogFragment {

    //your code

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new FitSystemWindowsBottomSheetDialog(getContext());
    }
}

public class FitSystemWindowsBottomSheetDialog extends BottomSheetDialog {

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

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getWindow() != null && Build.VERSION.SDK_INT >= 21) {
            findViewById(android.support.design.R.id.coordinator).setFitsSystemWindows(false);
            findViewById(android.support.design.R.id.container).setFitsSystemWindows(false);
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS |
                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        }
    }
}

And, finally, don't forget to add android:fitsSystemWindows="true" at the root of your dialog layout.

Hope it helps.
