我试过这个程序,如OpenGL ES2 for
Android所示,但它不工作!
我已经在Odroid E测试了,三星s3,三星y,三星星!
the gl version suported returns 2,but i get 11-22 15:09:45.804: E/oGl-es v(9047): 2.0:131072 11-22 15:09:45.804: E/libEGL(9047): call to OpenGL ES API with no current context (logged once per thread) 11-22 15:09:45.804: E/unable to(9047): createShader 11-22 15:09:45.804: E/libEGL(9047): call to OpenGL ES API with no current context (logged once per thread) 11-22 15:09:45.804: E/unable to(9047): createShader 11-22 15:09:45.804: E/libEGL(9047): call to OpenGL ES API with no current context (logged once per thread) 11-22 15:09:45.804: E/Error creating(9047): GL programObject 11-22 15:09:45.812: E/render(9047): set 11-22 15:09:46.062: E/Results of validating program:(9047): 0 11-22 15:09:46.062: E/Results of validating program:(9047): Log:
以下是我的代码
public class Main_OGLT1 extends Activity { MySurface mGLSurfaceView; private boolean renderSet; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mGLSurfaceView = new MySurface(this);//(this); //instantiation ActivityManager actMan = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE); ConfigurationInfo mConfigInfo = actMan.getDeviceConfigurationInfo(); boolean isES2Compat = (mConfigInfo.reqGlEsVersion >= 0x20000); Log.e("oGl-es v",mConfigInfo.getGlEsVersion()+":"+ mConfigInfo.reqGlEsVersion); if(isES2Compat){ renderSet = true; Log.e("render","set"); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main__oglt1,menu); return true; } @Override protected void onResume() { // The activity must call the GL surface view's onResume() on activity onResume(). super.onResume(); mGLSurfaceView.onResume(); } @Override protected void onPause() { // The activity must call the GL surface view's onPause() on activity onPause(). super.onPause(); mGLSurfaceView.onPause(); } }
MySurface类:
public class MySurface extends GLSurfaceView{ public MySurface(Context context) { super(context); // TODO Auto-generated constructor stub setEGLContextClientVersion(2); setRenderer(new MyTestRenderer(getContext())); } }
解决方法
问题在于glSurfaceView,因为它不会在OpenGL线程上运行. glSurfaceView应该在主要的android线程上.

希望这个帮助.
