Recycler view adapter that adds expandable / collapsible items

Expandable Recycler View

Setup

Add this to your root build.gradle for all your projects

allprojects {
  repositories {
        ...
        maven { url "https://jitpack.io" }
  }
}

Then add this to your build.gradle dependencies for the project where you want to use it

dependencies {
  ...
  compile 'com.github.grennis:ExpandableRecyclerView:0.9.3'
}

Usage

Define a recycler view adapter that derives from ExpandableRecyclerAdapter:

public class PeopleAdapter extends ExpandableRecyclerAdapter<PeopleAdapter.PeopleListItem> {
  ...
}

Define your items that derive from ExpandableRecyclerAdapter.ListItem

public static class PeopleListItem extends ExpandableRecyclerAdapter.ListItem {
  public PeopleListItem(String group) {
    super(TYPE_HEADER);
    ...
  }
}

Use the TYPE_HEADER for the expandable header items. Define other types as needed for your application.

You can set a mode to collapse other items when an item is opened:

adapter.setMode(ExpandableRecyclerAdapter.MODE_ACCORDION);
