android Add Badge on Expandablelistview

Question

I don't know how we can add Badge in ExpandableListView. I searched some keywords but no result talk about this. So I post picture and want to know this may occur? Thanks for supports.

Answer 1

Create two layout xml files for Group and Child views respectively - For example, group_layout.xml and child_layout.xml These layouts are inflated and used in the custom ExpandableListAdapter as shown below.

    <corners android:radius="20dp" />

    <solid android:color="#ff2233" />

</shape>
