I've been fighting with styling on ExpandableListView as well (an area that could use some improvement in a future release).
The problem with the current implementation is in the selector element for the group expander. It can be found in expander_group.xml and looks like this: <selector xmlns:android="http://schemas.android.com/apk/res/android";> <item android:state_expanded="true" android:drawable="@drawable/expander_ic_maximized" /> <item android:drawable="@drawable/expander_ic_minimized" /> </selector> The problem is that it lacks a state for empty. The code and attributes support it (state_empty) but it isn't defined in here. Here are the hypothetical (completely untested) steps you could use to achieve this: - Grab the existing expander_group.xml and put it into your drawable directory. - Modify it to include a section for the empty state with no image. Something like this: <item android:state_empty="true" android:drawable="@drawable/ empty"/> - Modify your ExpandableListView element and set the group indicator to be your private expander_group.xml Let us know how it works out. For myself, I need even more control so I'm about to move to the "roll my own" stage. On Feb 22, 8:35 pm, ls02 <[email protected]> wrote: > setGroupIndicator will set ALL groups indicator.
