How to use in a fragment?

rootView = inflater.inflate(R.layout.game_grid, container, false);//fragment layout
box = new DynamicBox(getActivity(), rootView);
box.showLoadingLayout();
the above is how I use in fragment.But it have some mistake:
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

hi @medyo
It also don't work. I think getView() is null.
Logcat show:
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Class java.lang.Object.getClass()' on a null object reference
at com.example.demo.view.DynamicBox.(DynamicBox.java:53)()
In DynamicBox.java:53 :Class viewClass = mTargetView.getClass(); mTargetView is getView().
Don't touch fragment view initialisation on onCreateView
Move your DynamicBox to onActivityCreated
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
DynamicBox mBox = new DynamicBox(getActivity(), MyView);
}
If issue still persists, try to wrap your fragment view using a LinearLayout or RelativeLayout
