本文介绍了如何在Cocos2d-x GLSurfaceView中通过自定义Cocos2dxRenderer来实现透明的OpenGL背景效果，并通过修改onSurfaceCreated方法来优化渲染性能。

I had to add some code in Cocos2dxGLSurfaceView.java

in the initView method :

mRenderer = new Cocos2dxRenderer();
      setFocusableInTouchMode(true);
      setEGLConfigChooser(8, 8, 8, 8, 16, 0);
      setRenderer(mRenderer);
      getHolder().setFormat (PixelFormat.TRANSLUCENT);

and in the Cocos2dxRenderer

modify the onSurfaceCreated(GL10 gl, EGLConfig config) method:

public void onSurfaceCreated(GL10 gl, EGLConfig config) {     
            nativeInit(Cocos2dxActivity.screenWidth, Cocos2dxActivity.screenHeight); 
            last = System.nanoTime();
            gl.glDisable(GL10.GL_DITHER);
            gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT,
                    GL10.GL_FASTEST);
             gl.glClearColor(0,0,0,0);
             gl.glEnable(GL10.GL_CULL_FACE);
             gl.glShadeModel(GL10.GL_SMOOTH);
             gl.glEnable(GL10.GL_DEPTH_TEST);
        }

With this I get a transparent openGLview background by the way I will make a post about my application done with cocos2dx for iPhone and android very soon
