Android 监听RecyclerView内部数据变化

RecyclerViewAdapter  mRecyclerViewAdapter = new RecyclerViewAdapter(mListingDataList);
      mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
      mRecyclerView.setAdapter(mRecyclerViewAdapter );
      mRecyclerViewAdapter .registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
            @Override
            public void onChanged() {
                super.onChanged();
                if (null != mTabLayoutOh)
                    mTabLayoutOh.setVisibility(!mListingDataList.isEmpty() ? View.VISIBLE : View.GONE);
            }
        });
           

一目了然。
