获取自定义布局的屏幕截图

Question

How do I take a screenshot of a custom layout from opencv? Is this code getWindow().getDecorView().getRootView() applicable with this custom view from opencv; get the bitmap out of it?

 <org.opencv.android.JavaCameraView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:visibility="gone"
    android:id="@+id/activity_java_surface_view"
    opencv:show_fps="true"
    opencv:camera_id="any" />

Does this code work?

view.setDrawingCacheEnabled(true);
Bitmap b = view.getDrawingCache();
