推荐答案

我已经解决了这个问题我自己，在机器人的底部借鉴导航栏上面，我必须给一个在Y位置偏移而确定在windowManager.Layout PARAMS如下图所示。

I have solved the issue myself , to draw on top of navigation bar at the bottom of the android , I have to give an offset in the Y position while defining the windowManager.Layout params as below.

w = new android.view.WindowManager.LayoutParams(-1, -1,0,-navigationBarHeight(),    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
    WindowManager.LayoutParams.FLAG_FULLSCREEN
    |WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
    |WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
    |WindowManager.LayoutParams.FLAG_LAYOUT_INSET_DECOR 
    |WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, Pixel.Translucent);
    f.addView(v, w);

请注意：这只有在导航栏是半透明

note: This only works when the navigation bar is translucent
