I use a XWalkView to load webpage and a IjkVideoView to play live video in my app. I want the IjkVideoView playing the video in front the XwalkView, so I put these two view in a relativelayout and IijVideoView behind the XWalkView.
In the android studio's Component Tree of Design window the layout seems ok as below image,
While when I run the app in my device, the layout is in mess as below image. You can see the background of IjkVieoView is in front of XWalkView, but the video playing in the IjkVideoView is behind the XWalkView, as the upper part of the video has been covered by the XWalkView.
