After adding the videoView is covered, not cover added videoView first

CodePudding user response:

My experiment, to successively adding two ImageView is normal
With mixed with the ImageView VideoView add, whichever first add is normal
Anyway, mix to add, change index is normal, why can't the rest of 2 VideoView, into two SurfaceView is also not line
