我创建了3D对象,我也在显示相机预览。 CameraPreview是
显示在XML文件中定义的SurfaceView上,3D对象显示在
上在XML文件中定义的framelayout。我想在
上显示旋转的3D对象CameraPreview,但是当我运行App时,CameraPreview正在显示少数
秒后,活动显示独立于
的3D旋转对象cameraPreview,我的意思是,旋转的3D对象不会显示在Camerapreview
上表面。有没有办法解决这个错误?
非常感谢你的帮助。
代码:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mpinfo);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER);
surfaceView = (SurfaceView)findViewById(R.id.camerapreview);
surfaceView.setZOrderOnTop(true);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.setFormat(PixelFormat.TRANSPARENT);
surfaceHolder.addCallback(this);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
// TODO Auto-generated method stub
if(previewing){
camera.stopPreview();
previewing = false;
}
if (camera != null){
try {
camera.setPreviewDisplay(surfaceHolder);
camera.startPreview();
previewing = true;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
// TODO Auto-generated method stub
camera = android.hardware.Camera.open();
//Create an Instance with this Activity
glSurface = new GLSurfaceView(this);
//Set our own Renderer
glSurface.setRenderer(new Lesson05());
//Set the GLSurface as View to this Activity
fl01 = (FrameLayout) findViewById(R.id.fl01);
//setContentView(glSurface);
//fl01.addView(cameraSurface);
fl01.addView(glSurface);
}
