mRecyclerViewTop = findViewById(R.id.top);   
PagingScrollHelper pagingScrollHelper1 = new PagingScrollHelper();       
pagingScrollHelper1.setUpRecycleView(mRecyclerViewTop);       
mRecyclerViewTop.setLayoutManager(new HorizontalPageFlowLayoutManager());     
mRecyclerViewTop.setAdapter(testAdapter);

mRecyclerViewMid = findViewById(R.id.mid);      
PagingScrollHelper pagingScrollHelper2 = new PagingScrollHelper();       
pagingScrollHelper2.setUpRecycleView(mRecyclerViewMid);       
mRecyclerViewMid.setLayoutManager(new HorizontalPageFlowLayoutManager(0, 3));   
mRecyclerViewMid.setAdapter(testAdapter);
 
mRecyclerViewBottom = findViewById(R.id.bottom);    
PagingScrollHelper pagingScrollHelper3 = new PagingScrollHelper();       
pagingScrollHelper3.setUpRecycleView(mRecyclerViewBottom);     
final HorizontalPageFlowLayoutManager layoutManager = new HorizontalPageFlowLayoutManager(4,4);    
mRecyclerViewBottom.setLayoutManager(layoutManager);
