检测手机是否支持OpenGL 基本都支持
/*检测是否支持OpenGLEs2.0*/
private void checkSupported() {
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
ConfigurationInfo configurationInfo = activityManager.getDeviceConfigurationInfo();
supportsEs2 = configurationInfo.reqGlEsVersion >= 0x2000;
boolean isEmulator = Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1
&& (Build.FINGERPRINT.startsWith("generic")
|| Build.FINGERPRINT.startsWith("unknown")
|| Build.MODEL.contains("google_sdk")
|| Build.MODEL.contains("Emulator")
|| Build.MODEL.contains("Android SDK built for x86"));
supportsEs2 = supportsEs2 || isEmulator;
}
Activity的生命周期
/*生命周期*/
@Override
protected void onPause() {
super.onPause();
glSurfaceView.onPause();
}
@Override
protected void onResume() {
super.onResume();
glSurfaceView.onResume();
}
全部Activity代码
public class MainActivity extends AppCompatActivity {
private boolean supportsEs2;
private GLSurfaceView glSurfaceView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
checkSupported();
if (supportsEs2){
glSurfaceView = new GLSurfaceView(this);
glSurfaceView.setEGLConfigChooser(8,8,8,8,16,0);
glSurfaceView.setRenderer(new GLRenderer());
setContentView(glSurfaceView);
}else{
// setContentView(R.layout.activity_main);
Toast.makeText(MainActivity.this,"暂不支持OpenGL",Toast.LENGTH_SHORT).show();
}
}

1Render 中代码
public class GLRenderer implements GLSurfaceView.Renderer {
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
}
@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
}
@Override
public void onDrawFrame(GL10 gl) {
}
}
2 Renderer显示背景颜色
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
gl.glClearColor(1f, 0f, 0f, 0f);
}
@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
gl.glViewport(0, 0, width, height);
}
@Override
public void onDrawFrame(GL10 gl) {
gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
}
