Setup

The Gradle dependency is available via jCenter.

Add this to your

build.gradle
file.
gradle
implementation 'com.github.zhukic:sectioned-recyclerview:1.2.3'

How it works

The main idea of the library is to determine whether to place a subheader between a pair of neighboring items. To do this, you need to implement the

onPlaceSubheaderBetweenItems
method, which returns
true
when you need to place a subheader between two neighboring items,
false
- otherwise. ```java @Override public boolean onPlaceSubheaderBetweenItems(int position) { final char movieTitleFirstCharacter = movieList.get(position).getTitle().charAt(0); final char nextMovieTitleFirstCharacter = movieList.get(position + 1).getTitle().charAt(0);
//The subheader will be placed between two neighboring items if the first characters in movie titles are different.
return movieTitleFirstCharacter != nextMovieTitleFirstCharacter;

} ```

Sample

Please try out sample app for more details. Or:

Grid

If you are using a

GridLayoutManager
set it to adapter.
java
GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), 2);
sectionedRecyclerAdapter.setGridLayoutManager(gridLayoutManager);
