popuWindow 快速点击，背景透明

gistfile1.java

//背景不透明
mPopupWindow.setBackgroundDrawable(null);

final View contentView = getContentView();
//设置触摸事件 给 PopupWindow的ContentView重新设置触摸事件 解决setOutsideTouchable(true) 失效了，contentView为popuwindow的View
contentView.setOnTouchListener(new View.OnTouchListener() {
	@Override
	public boolean onTouch(View v, MotionEvent event) {
		final int x = (int) event.getX();
		final int y = (int) event.getY();
		
		if ((event.getAction() == MotionEvent.ACTION_DOWN)
				&& ((x < 0) || (x >= getWidth()) || (y < 0) || (y >= getHeight()))) {
			dismiss();
			return true;
		} else if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
			dismiss();
			return true;
		} else {
			return contentView.onTouchEvent(event);
		}
	}
});
