How to stop OpenGL ES drawing background color on Android?

Now I wan开发者_如何学运维t to insert a ImageView behind the GLSurfaceView.But the GLSurfaceView always draws background color so I can't see the ImageView.I tried glClearColor(0,0,0,0) but it doesn't work.What should I do?Please help me! Thank you very much.

If I remember correctly you should be able to adapt this

Overlapping Views in Android

to your needs

(relative layout and android:background="#0000")

since GLSurfaceView is a View it should work.

I fixed it. using

    gLSurfaceView.setEGLConfigChooser(8,8,8,8,16,0);
    gLSurfaceView.setRenderer(this);
    RelativeLayout rl = new RelativeLayout(this);
    BgLayout bgl = new BgLayout(this);
    gLSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
    gLSurfaceView.setZOrderOnTop(true);
    rl.addView(bgl);
    rl.addView(gLSurfaceView);
