Show AlertDialog with ImageView without any padding

Question

EDIT - SOLUTION:

I ended up figuring out a way to solve this issue. Because manually changing the height of the ImageView removes the extra padding,

Answer 1

Im not quite sure, but I think its the type of dialog you are showing that adds the padding. This type of dialog does not hide the entire activity. What I use to hide the entire activity is:

/**
 * Show the overlay using the WindowManager class.
 * @param overlay The overlay that needs to be shown.
 */
public void showOverlay(View overlay) {
    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
                    WindowManager.LayoutParams.FLAG_FULLSCREEN,
            PixelFormat.TRANSLUCENT);

    getWindowManager().addView(overlay, params);
}

You could probably find an option that does what you need. However you will need to create a layout containing the buttons and image should you want to use the above method.
