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);
