Demos

Getting started

Define RecyclerTabLayout in xml layout with custom attributes.

<com.nshmura.recyclertablayout.RecyclerTabLayout
        android:id="@+id/recycler_tab_layout"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        rtl_tabIndicatorColor="?attr/colorAccent"
        rtl_tabIndicatorHeight="2dp"
        rtl_tabBackground="?attr/selectableItemBackground"
        rtl_tabTextAppearance="@android:style/TextAppearance.Small"
        rtl_tabSelectedTextColor="?android:textColorPrimary"
        rtl_tabMinWidth="72dp"
        rtl_tabMaxWidth="264dp"
        rtl_tabPaddingStart="12dp"
        rtl_tabPaddingTop="0dp"
        rtl_tabPaddingEnd="12dp"
        rtl_tabPaddingBottom="0dp"
        rtl_tabPadding="0dp"/>

Set up with the ViewPager.

ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
viewPager.setAdapter(adapter);

RecyclerTabLayout recyclerTabLayout = (RecyclerTabLayout) findViewById(R.id.recycler_tab_layout);
recyclerTabLayout.setUpWithViewPager(viewPager);

Or set up with ViewPager and Custom RecyclerView.Adapter that's extends RecyclerTabLayout.Adapter.

ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
viewPager.setAdapter(adapter);

RecyclerTabLayout recyclerTabLayout = (RecyclerTabLayout) findViewById(R.id.recycler_tab_layout);
recyclerTabLayout.setUpWithAdapter(new CustomRecyclerViewAdapter(viewPager));

Here's sample of custom RecyclerView adapter.

public class CustomRecyclerViewAdapter extends RecyclerTabLayout.Adapter<CustomRecyclerViewAdapter.ViewHolder> {

    public DemoCustomView01Adapter(ViewPager viewPager) {
        super(viewPager);
        ...
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        // Inflate your view.
        View view = ...;
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        // Bind data
        ...
        
        if (position == getCurrentIndicatorPosition()) {
            //Highlight view
        }
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        ...
        
        public ViewHolder(View itemView) {
            super(itemView);
        ...
        }
    }
}
