I tried to set it as background transparency in XML, but it didn't work. The first method is to obtainProgramAnd then draw the background before surfaceview. This method is really stupid. After reading the document today, I found thatCodeYou can set the following settings to make the background transparent. Record.

Msurfaceview. setzorderontop (true );
Msurfaceview.Getholder (). setformat (pixelformat. translucent );
