GL线程

 1 public class MiniLauncher extends AndroidApplication implements MenuActionListener {

    public View glView =null;
    public DesktopListener mListener;
    @Override
    public void onCreate(Bundle savedInstanceState) {
    
       //得到的是一个surfaceView
        glView = initializeDesktop(mListener, true);
        setContentView(glView);
    
    }
    
    public View initializeDesktop(DesktopListener listener,
            boolean useGL2IfAvailable) {
    
        return initializeForView(listener, config);
    
    
    
     }
}

   以下是gdx自己创建新线程的流程：

AndroidApplication:

protected AndroidGraphics graphics;
protected ApplicationListener listener;
public View initializeForView (ApplicationListener listener, AndroidApplicationConfiguration config) {
    //graphics will create another thread for ui drawing
    graphics = new AndroidGraphics(this, config, config.resolutionStrategy == null ? new FillResolutionStrategy()
            : config.resolutionStrategy);
    this.listener = listener;
}

AndroidGraphics:
final View view;
    public AndroidGraphics (AndroidApplication activity, AndroidApplicationConfiguration config,
        ResolutionStrategy resolutionStrategy) {
        //thread created here
        view = createGLSurfaceView(activity, config.useGL20, resolutionStrategy);    
        this.app = activity;
    }
    
    private View createGLSurfaceView (Activity activity, boolean useGL2, final ResolutionStrategy resolutionStrategy) {
        GLSurfaceView20 view = new GLSurfaceView20(activity, true,16,0,resolutionStrategy);
        view.setRenderer(this);
        return view;
    }
    
    @Override
    public void onDrawFrame (javax.microedition.khronos.opengles.GL10 gl) {
    
        //这里的 listener 就是 d3dListener
       if (lresume) {
           app.listener.resume();
       }
       if (lrunning) {
              app.listener.render();
       }
       if (lpause) {
            app.listener.pause();
        }
        if (ldestroy) {
            app.listener.dispose();
        }
    
    }
GLSurfaceView:

 public void setRenderer(Renderer renderer) {
      mGLThread = new GLThread(renderer);
      mGLThread.start();
 }
 
  class GLThread extends Thread {
    mRenderer = renderer;
      public void run() {
       guardedRun();
    }
      
    private void guardedRun() throws InterruptedException {
         while (true) {
         
            //mRenderer 就是 graphics
            mRenderer.onDrawFrame(gl);
         
         }
       
       }
  }
