android Opengl中使得一个view在另一个view上面显示

 public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        LoadImage.load(getResources());        myRenderer = new MyRenderer(true);        glSurfaceView = new GLSurfaceView(this);        glSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 0);        glSurfaceView.setRenderer(myRenderer);        glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);        glSurfaceView.setZOrderOnTop(true);        setContentView(glSurfaceView);    }
