GLSurfaceView 是一个视图，继承至SurfaceView，它内嵌的surface专门负责OpenGL渲染。

在使用的时候要实现以下几步。

一、创建自定义1类继承自GLSurfaceView，并创建构造器

二、创建自定义2类实现GLSurfaceView.Renderer接口

　　重写onDrawFrame(GL10 gl)、 onSurfaceChanged(GL10 gl, int width, int height)、onSurfaceCreated(GL10 gl, EGLConfig config)方法

三、在自定义1中定义自定义类2，并在自定义类1的构造方法中调用setRenderer(renderer);方法进行渲染器设置

四、在主Ativity中创建自定义类1，并将其设置为视图，为了使GLSurfaceView能够与Activity同步，要重写Activity的onPouse和onResume方法，并分别在相应的方法中调用GLSurfaceView的onPouse和onResume方法。
