将Rajawali表面视图布局参数设置为等于JavaCameraView

Question

我正在尝试使用Rajawali库在我的JavaCameraView上放置一个3d对象。我已经为JavaCameraView设置了最大帧大小，如下所示：

javaCameraView.setMaxFrameSize（640,480）;

我希望我的表面布局参数与javacameraview（宽度和高度）的布局参数匹配，但不知怎的，我无法实现。我该怎么做？

     @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    javaCameraView = (JavaCameraView) findViewById(R.id.java_camera_view);
    javaCameraView.setVisibility(View.VISIBLE);
    javaCameraView.setCvCameraViewListener(this);
    javaCameraView.setMaxFrameSize(640,480);


    final RajawaliSurfaceView surface = new RajawaliSurfaceView(this);
    surface.setFrameRate(60.0);
    surface.setRenderMode(IRajawaliSurface.RENDERMODE_WHEN_DIRTY);
    surface.setTransparent(true);
    surface.setBackgroundColor(Color.MAGENTA);

    javaCameraView.setLayoutParams(new RelativeLayout.LayoutParams(640, 480));
    // Add mSurface to your root view
    addContentView(surface, new RelativeLayout.LayoutParams(320, 240));


    renderer = new Renderer(this);
    surface.setSurfaceRenderer(renderer);

    Log.d("NATIVE LOG", "Initialisation complete");
}
