ExpandableListView is showing indicator for groups with no child

Question

I'm creating an `ExpandableListView` with data from a database. For that, I'm using a `CursorTreeAdapter` and I populate it with a `Cursor` object which contains the data I retrieve from database. I thought that, by default Android would consider the groups with no child "not expandable". However it still shows the expand icon on the row, and when I click it, it does nothing. I don't want it to show this icon. I want only the groups that has childs to show the expand icon, which is not happening. It shows the expand icon for all rows (those with child and with no child). UPDATE I've studied my code and I've seen that the problem is basically in setting the `groupIndicator` for the groups. However I've tried a lot of approaches like creating a selector and setting it's drawable based on state and expandable, like this: ```

Accepted Answer

In your xml add the folowing to ExpandableListView:

```
    android:groupIndicator="@android:color/transparent"
```

Than each Group Item View in your Adapter needs its internal indicator. You can for example add a ImageView on the right side in your .xml.

Then in the Adapter you do the following:

```
@Override
protected void bindGroupView(View view, Context paramContext, Cursor cursor, boolean paramBoolean) 
    ...

if (getChildrenCount(groupPosition) > 0) {
        viewHolder.indicator.setVisibility(View.VISIBLE);
        viewHolder.indicator.setImageResource(
                isExpanded ? R.drawable.indicator_expanded : R.drawable.indicator);
    } else {
        viewHolder.indicator.setVisibility(View.GONE);
    }
}
```
