Hi,

I got a NullPointerException:

mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
LinearLayoutManager llm = new LinearLayoutManager(getActivity());
mRecyclerView.setLayoutManager(llm);

mMaterialScrollBar = new DragScrollBar(getActivity(), mRecyclerView, true);
mMaterialScrollBar.setHandleColourRes(R.color.main_green);

java.lang.NullPointerException: Attempt to read from field 'float android.graphics.RectF.left' on a null object reference
