Recycler view adapter that adds expandable / collapsible items
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'
}
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);
