Add two sections in recyclerview android

If you already have a RecyclerView, an easy way to implement the sections is using Gabriele Mariotti’s SimpleSectionedRecyclerViewAdapter.

I paste you his example:

//Your RecyclerView
mRecyclerView = (RecyclerView) findViewById(R.id.list);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.addItemDecoration(new DividerItemDecoration(this,LinearLayoutManager.VERTICAL));

//Your RecyclerView.Adapter
mAdapter = new SimpleAdapter(this,sCheeseStrings);


//This is the code to provide a sectioned list
List<SimpleSectionedRecyclerViewAdapter.Section> sections =
        new ArrayList<SimpleSectionedRecyclerViewAdapter.Section>();

//Sections
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(0,"Section 1"));
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(5,"Section 2"));
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(12,"Section 3"));
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(14,"Section 4"));
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(20,"Section 5"));

//Add your adapter to the sectionAdapter
SimpleSectionedRecyclerViewAdapter.Section[] dummy = new SimpleSectionedRecyclerViewAdapter.Section[sections.size()];
SimpleSectionedRecyclerViewAdapter mSectionedAdapter = new
          SimpleSectionedRecyclerViewAdapter(this,R.layout.section,R.id.section_text,mAdapter);
mSectionedAdapter.setSections(sections.toArray(dummy));

//Apply this adapter to the RecyclerView
mRecyclerView.setAdapter(mSectionedAdapter);
