Android GLSurfaceView with drawable background

问题

I have a GLSurfaceView with a drawable as background, however only the background is visible when rendered without surfaceView.setZOrderOnTop(true)

I need to avoid using setZOrderOnTop(true) because there are static TextView's being used on top of the GLSurfaceView.

Any suggestions for getting this to work?

回答1:

GLSurfaceView cannot really have a background. The way a surface view works is by cutting a hole through your Activity's window and showing another surface behind. Setting setZOrderOnTop(true) moves the surface above the Activity's window.

回答2:

false! You can do it. Just an example to show how it works.

glRenderer  = new OpenGLRenderer(context);
view = new GLSurfaceView(context);
view.setEGLConfigChooser(8, 8, 8, 8, 16, 0);
view.setRenderer(glRenderer);
view.getHolder().setFormat(PixelFormat.RGBA_8888);
view.getHolder().setFormat(PixelFormat.TRANSLUCENT);
view.setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);

Then use framelayout to put a view under glsurfaceview!

回答3:

Try setZOrderMediaOverlay(true); which should put the gl layer above the background but below the window.

回答4:

Well, since GLSurfaceView is just another view, why not use a FrameLayout to place the GLSurfaceView on top of the ImageView (or whatever you're using to display the drawable.)
