Question

我一直在关注Android的Open GL上的this系列，但每当我运行第一个程序时它就会在启动时崩溃。我可能在他们的代码中遗漏了一些东西，但我检查了三次。它与活动xml文件有关吗？

这是完整的日志信息

尽管文档未指定为强制性文档，但有时您似乎必须在GLSurfaceView.setRenderer之前调用GLSurfaceView.setEGLConfigChooser

试试这个初始化代码：

public class MyGLActivity extends Activity {
    //...    
    private GLSurfaceView glView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        glView = new GLSurfaceView(this);
        glView.setEGLConfigChooser(8 , 8, 8, 8, 16, 0);
        glView.setRenderer(new MyGlRenderer(this));
        this.setContentView(glView);
    }
    //...
}
