Android-Mapbox方向更改丢失对MapboxMap的引用

Question

不言自明-我在viewpager片段中有一个MapboxMap，如果屏幕旋转了，我将丢失对地图的引用（即，对于任何其他方法调用，map = null）。我已经实现了所有片段状态更改到最后，包括OnDestroyView，所以不确定发生了什么。以下是我的MapFragment.java的摘录。

@Override
public void onAttach(Context context) {
    Log.i(TAG,"Attaching Map");
    super.onAttach(context);
    mContext = context;
    if (context instanceof OnFragmentInteractionListener) {
        mListener = (OnFragmentInteractionListener) context;
    } else {
        throw new RuntimeException(context.toString()
                + " must implement OnFragmentInteractionListener");
    }
}

@Override
public void onDetach() {
    Log.i(TAG,"Detaching Map");
    super.onDetach();
    mListener = null;
}

@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
    return false;
}
