Question

I’m currently developing a game, which only uses 2D graphics.

In the game i extensively use android’s SurfaceView to display my graphics.
I’ve heard that GLSurfaceView uses Hardware-accelerated graphics, and i can increase performance of my app using that instead of the current SurfaceView.

Currently, i have a class extending SurfaceView, which updates and renders the game state, when methods update() and render() are called by my own thread class extending Thread. The Thread basically helps me maintain a nearly constant FPS.

NOW THE PROBLEM:
How do i change from SurfaceView to GLSurfaceView, and call methods to update and render game state from the Thread, to still have control over the FPS. I read the android documentation on OpenGL ES, and i can’t quite understand how to use the GLSurfaceView.Renderer.

If someone can explain how can i easily switch from SurfaceView to GLSurfaceView, It’d be of great help! Thanks!

Answer 1

The Class that displays your game will extend GLSurfaceView. Your rendering class will implement Renderer. In your Renderer class you will need to add these unimplemented methods: onDrawFrame(), onSurfaceChanged(), and onSurfaceCreated().

Hope this helps.
