getLocationOnScreen() will get the location based on the phone screen.
getLocationInWindow() will get the location based on the activity window. 水滴屏獲取位置用這種

4.Button在約束布局中擋住其他view锡溯，是因為button自帶elevation，在Z軸上高于其他view魏割。
Button和TextView的不同
Button 有背景，點擊，按下都有相應(yīng)的效果眨八。
可點擊。
默認(rèn)有焦點左电。
樣式不同廉侧，比如顏色页响，位置等
5.removeView由于有LayoutTransition而刪除失敗
6.彈出dialog時，window不退出全屏段誊，虛擬鍵不彈出
在show 之前 闰蚕，getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
