Solution

  • a custom drawable is probably what you need. You cant toy with the in built indicator. have a look at this. The group_indicator.xml at the bottom of that page is an example of a custom indicator. You just add this drawable to the android:groupindicator value of you expandablelistview element. This way you can control the indicator behavious and size and with aa few tweaks also hide the indicator if there are no children in the group.

        <selector xmlns:android="http://schemas.android.com/apk/res/android">  
        <item android:state_empty="true" android:drawable="@drawable/arrowright">  
        <item android:state_expanded="true" android:drawable="@drawable/arrowdown">  
        <item android:drawable="@drawable/arrowright">  
        </item></item></item>  
    </selector>

    Hope it helps.
