How to create on click event for children in Expandable list.

Question

Hello.

I am playing around with this example. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList2.html

I cannot figure out how to attach a listener to the children elements so that I can trigger some action when the user taps on the phone number.

Any code or links would be greatly appreciated.

Answer 1

You need to subscribe to setOnChildClickListener

getExpandableListView().setOnChildClickListener(this);

and implement OnChildClickListener

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition,
        int childPosition, long id) {
    // use groupPosition and childPosition to locate the current item in the adapter
    return true;
}

Answer 2

You should override onChildClick in your ExpandableListActivity extension.
