在简单的Java程序中从JButton打开一个URL？(Opening a URL from a JButton in simple Java Program?)

 好的，我想我已经整理出来了。 设置渲染模式的地方似乎是包含您的GLSurfaceView对象的类，而不是GLSurfaceView构造函数。 另外（我认为我在GLSurfaceView的Android文档中忽略了一些 ），在设置渲染器之前，您无法设置GLSurfaceView的渲染模式。 这也许就是为什么试图在构造函数中设置渲染模式不起作用的原因。 
 
 这似乎迫使它只在我想要的时候渲染，这正是我想要的： 
 
public class Game extends Activity {
private GLSurfaceView glSurface;
private SurfaceViewClass svc;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    glSurface = (GLSurfaceView) findViewById(R.id.SurfaceView01);

    svc = new SurfaceViewClass(this);
    glSurface.setRenderer(svc);
    glSurface.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
}

public void movePlayer() {
    svc.highlightSpot(location[PLAYER], 0);
    glSurface.requestRender();
}
}

OK, I think I got this sorted out. The place to set the render mode seems to be the class that contains your GLSurfaceView object, not in the GLSurfaceView constructor. Also (something I think I overlooked in the Android documentation for GLSurfaceView) you can't set the render mode of the GLSurfaceView before you set its renderer. This is perhaps why attempting to set the render mode in the constructor does not work.
 
This seems to force it to render only when I want it to, which is exactly what I wanted:
 
public class Game extends Activity {
private GLSurfaceView glSurface;
private SurfaceViewClass svc;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    glSurface = (GLSurfaceView) findViewById(R.id.SurfaceView01);

    svc = new SurfaceViewClass(this);
    glSurface.setRenderer(svc);
    glSurface.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
}

public void movePlayer() {
    svc.highlightSpot(location[PLAYER], 0);
    glSurface.requestRender();
}
}
