Question

我在我的Android应用程序中使用SurfaceView作为我的Activity的一部分（请参阅下面的截图），因为我已经编写了以下代码 -

我的XML代码是---

    <include
        android:id="@+id/createRevProgress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        layout="@layout/progressbar_medium" />

</RelativeLayout>

我的Java代码是 -

cameraSurfaceView = (SurfaceView) findViewById(R.id.videoSurface);
        cameraView = new CameraView();

        SurfaceHolder surfaceHolder = cameraSurfaceView.getHolder();
        try 
        {
            //surfaceHolder.setFixedSize(cameraSurfaceView.getWidth(), cameraSurfaceView.getHeight());
            //surfaceHolder.setSizeFromLayout();
            surfaceHolder.addCallback(cameraView);
            surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        } 
        catch (Exception e) 
        {
            Log.d("debug", "Another exception");
            e.printStackTrace();
        }
