        </android.support.design.widget.TabLayout>

    </android.support.design.widget.AppBarLayout>

</android.support.design.widget.CoordinatorLayout>

3、viewpager中如果多次使用

android.support.v7.widget.RecyclerView

可以在最外层使用

android.support.v4.widget.NestedScrollView

并设置

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
linearLayoutManager.setSmoothScrollbarEnabled(true);
linearLayoutManager.setAutoMeasureEnabled(true);

recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setNestedScrollingEnabled(false);
mAdapter = new MallRecommendAdapter(getActivity(), list);
recyclerView.setAdapter(mAdapter);
