Usage

Create a row of your RecyclerView:

<com.hendraanggrian.recyclerview.widget.ExpandableItem
    android:id="@+id/row"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:duration="500"
    app:layoutHeader="@layout/view_content"
    app:layoutContent="@layout/view_header"/>

Create your adapter, which must extend ExpandableRecyclerView.Adapter:

public class MyAdapter extends ExpandableRecyclerView.Adapter<MyAdapter.ViewHolder> {

    public MyAdapter(LinearLayoutManager layout) {
        super(layout);
        ...
    }

    @Override
    public void onBindViewHolder(MyAdapter.ViewHolder holder, final int position) {
        super.onBindViewHolder(holder, position);
        ...
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        ...
    }
}

Have an ExpandableRecyclerView somewhere in your app, regular RecyclerView works too.

<com.hendraanggrian.recyclerview.widget.ExpandableRecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Then pass LinearLayoutManager to the adapter:

LinearLayoutManager layout = new LinearLayoutManager(this);
RecyclerView.Adapter adapter = new MyAdapter(layout);

recyclerView.setLayoutManager(layout);
recyclerView.setAdapter(adapter);
