详解Android获得系统GPU参数 gl.glGetString

详解Android获得系统GPU参数 gl.glGetString

通过文档的查找，以及源码的剖析，Android的GPU信息需要通过OpenGL来获取，android framework层提供GL10来获取相应的参数，而GL10要在使用自定义的View时才可以获得，下面是获得GPU信息的例子：

1.实现Render类

class DemoRenderer implements GLSurfaceView.Renderer { 
 
  public void onSurfaceCreated(GL10 gl, EGLConfig config) 
  { 
    Log.d("SystemInfo", "GL_RENDERER = " +gl.glGetString(GL10.GL_RENDERER));  
    Log.d("SystemInfo", "GL_VENDOR = " + gl.glGetString(GL10.GL_VENDOR));  
    Log.d("SystemInfo", "GL_VERSION = " + gl.glGetString(GL10.GL_VERSION));  
    Log.i("SystemInfo", "GL_EXTENSIONS = " + gl.glGetString(GL10.GL_EXTENSIONS));  
  } 
 
 
  @Override 
  public void onDrawFrame(GL10 arg0) { 
    // TODO Auto-generated method stub 
 
  } 
 
 
  @Override 
  public void onSurfaceChanged(GL10 arg0, int arg1, int arg2) { 
    // TODO Auto-generated method stub 
 
  } 
 
} 

2.实现GLSurfaceView

class DemoGLSurfaceView extends GLSurfaceView { 
 
  DemoRenderer mRenderer; 
  public DemoGLSurfaceView(Context context) { 
    super(context); 
    setEGLConfigChooser(8, 8, 8, 8, 0, 0); 
    mRenderer = new DemoRenderer(); 
    setRenderer(mRenderer); 
  } 
} 

3.在Activity中 new 一个 DemoGLSurfaceView 对象

4.设置这个View对象

public class Demo extends Activity { 
  @Override 
  public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    GLSurfaceView glView = new DemoGLSurfaceView(this); 
    this.setContentView(glView); 
  } 
} 

以上就是Android获取GPU 参数的例子，如果大家研究Android GPU 的知识，必须研究Android GPU的源码，这里只是给个小例子，希望能帮助到大家，谢谢大家对本站的支持！
