Make overlay receive motionevents from under autohidden (translucent) navigation bar?
I have a small overlay on the bottom of the screen, which works as intended. However, when an autohidden navigation bar is temporarily exposed (aka it's translucent), the overlay no longer receives motionevents. I can see it there, properly placed at the bottom, but the navigation bar takes all the events. I have noticed some apps that boast "navigation gestures" are somehow able to get motionevents, meaning a user can swipe up even when the navigation bar is exposed, and that app will still get the events. How is this possible? I have tried every combination of flags I can think of, but nothing works.
Point screen_size = new Point();
WindowManager.LayoutParams mParams;
WindowManager mWindowManager = getSystemService(WINDOW_SERVICE);
mWindowManager.getDefaultDisplay().getRealSize(screen_size);
layout = new LinearLayout(getApplicationContext());
layout.setOnTouchListener(this);
// color for debug.
layout.setBackgroundColor(0x55ff0000);
mParams = new WindowManager.LayoutParams(
screen_size.x,
40,
0,
0,
WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
Wi ndowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
mParams.gravity = Gravity.BOTTOM;
mWindowManager.addView(layout, mParams);
