如何停止 Open GL 渲染器

发布于 2025-01-01 17:18:19 字数 617 浏览 3 评论 0原文

由于某种原因，我需要重新启动 GLSurfaceView.Renderer，因此我需要在应用程序中花一些时间再次调用 setRenderer(newRenderer)，Android 不喜欢这种做法，并会抛出 IllegalStateException 说“setRenderer 已被调用”。现在，

我知道这是因为渲染器附加到 GLSurfaceView，我需要将此渲染器与表面视图解除绑定，以便我可以再次调用 setRenderer。

有人有解决方案吗？

附：代码如下所示：

render = new Renderer(this);

setContentView(R.layout.main);
graphicView = (GLSurfaceView) this.findViewById(R.id.graphicView);

//DO STUFF

graphicView.setRenderer(render);

//DO STUFF

Renderer newRender = new Renderer();
graphicView.setRenderer(newRender); <= ...and Android hates this line sooo much

谢谢！

For some reason, I need to restart a GLSurfaceView.Renderer so I want some time in my app to call setRenderer(newRenderer) a second time, which Android doesn't like and throws a IllegalStateException saying "setRenderer has already been called"...

Now, I know this is because the renderer is attached to the GLSurfaceView and I need to unbind this renderer to the surface view, so I can call again setRenderer.

Anyone has a solution for this ?

P.S.:
Code looks like this :

render = new Renderer(this);

setContentView(R.layout.main);
graphicView = (GLSurfaceView) this.findViewById(R.id.graphicView);

//DO STUFF

graphicView.setRenderer(render);

//DO STUFF

Renderer newRender = new Renderer();
graphicView.setRenderer(newRender); <= ...and Android hates this line sooo much

Thanks !

在这里找到了答案，这个“LemonDev”确实救了我life ：

可以停止/销毁 OpenGL 表面视图，并通过调用 OnPause() 和 postDelayed 销毁来将新的 GLSurfaceView 设置为新的渲染器处理程序和一个 Runnable，如下所示：

final Renderer newRender = new GRenderer(this);
final LinearLayout ll = (LinearLayout) this.findViewById(R.id.main);
graphicView.onPause();

Handler handler = new Handler();
class RefreshRunnable implements Runnable{

    public RefreshRunnable(){

    }

    public void run(){
        ll.removeView(findViewById(R.id.graphicView));

        GLSurfaceView surfaceview = new GLSurfaceView(getApplication());
        surfaceview.setId(R.id.graphicView);
        surfaceview.setRenderer(newRender);

        ll.addView(surfaceview);

        graphicView = (GLSurfaceView) findViewById(R.id.graphicView);
    }
};

RefreshRunnable r = new RefreshRunnable(this);
handler.postDelayed(r, 500);

这将创建一个新的渲染器并暂停 GLSurfaceView。然后，应用程序将“销毁”一些您无法使用 SDK 触及的内部内容...之后，您可以销毁 GLSurfaceView，创建另一个并为其设置新的渲染器。

我现在的问题是纹理尚未刷新，但是，这仍然很棒！

Found the answer here, this "LemonDev" do saved my life :

One can stop/destroy an OpenGL surface view and set the new GLSurfaceView a new renderer by calling the OnPause() and postDelayed the destruction with a Handler and a Runnable, like this :

final Renderer newRender = new GRenderer(this);
final LinearLayout ll = (LinearLayout) this.findViewById(R.id.main);
graphicView.onPause();

Handler handler = new Handler();
class RefreshRunnable implements Runnable{

    public RefreshRunnable(){

    }

    public void run(){
        ll.removeView(findViewById(R.id.graphicView));

        GLSurfaceView surfaceview = new GLSurfaceView(getApplication());
        surfaceview.setId(R.id.graphicView);
        surfaceview.setRenderer(newRender);

        ll.addView(surfaceview);

        graphicView = (GLSurfaceView) findViewById(R.id.graphicView);
    }
};

RefreshRunnable r = new RefreshRunnable(this);
handler.postDelayed(r, 500);

This will create a new renderer and pause the GLSurfaceView. The application then will "destroy" some internal stuffs that you can't touch with the SDK... After this, you can destroy the GLSurfaceView, create another one and set the new renderer to it.

My problem now is that the textures are not refreshed yet but, still, this is great !
