Question

Is there a way to show expandable and non expandable list in the same list view?
What I am trying to achieve is to have expandable list view but for items that don’t have sub items, and I don’t want to show the arrow expand arrow icon
How how can I do that? Please help
Thanks

EDIT: All what I want is to be able to hide indicator arrow when group is empty

1) Basically, you have to hide “expand arrow” when group has no child.
You can achieve this by setting GroupIndicator property to null.

For ex : getExpandableListView().setGroupIndicator(null);

OR

2) by checking the children count you can set the indicator like the below code,

   if ( getChildrenCount( groupPosition ) == 0 ) {
       indicator.setVisibility( View.INVISIBLE );
    } else {
       indicator.setVisibility( View.VISIBLE );
       indicator.setImageResource( isExpanded ? R.drawable.list_group_expanded : R.drawable.list_group_closed );
    }

For more information about hiding Group indicator, you can refer this link.

OR

3) Create a group_indicator.xml file in drawable folder

<item android:state_empty="true" android:drawable="@android:color/transparent"></item>
<item android:state_expanded="true" android:drawable="@drawable/arrowdown"></item>
<item android:drawable="@drawable/arrowright"></item>

Then, define expandable list view like the below code,

   <ExpandableListView
        android:id="@+id/android:list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:groupIndicator="@drawable/group_indicator"
        android:layout_weight="1" >
    </ExpandableListView>

Hope this will solve your problem.
