How can I implement idle timeout in android?

How do we implement a 3-level expandable list view in Android and make the childs in the final view clickable?

• I get the data for theExpandable listview at the runtime (of course has the format beforehand).How can I implement this?(Any tutorial links are helpful). Example: First Level:Displays names.Click on any name expands another Expandable List view Second Level:Click on any individual item in the List gives aother ListView which is final View and the childs in this are to be clickable

• Answer:

  Note: You should not combine any scrollable widgets (like ListView inside another ListView). ExpandableListView is designed to handle two layers not more, don't try it, it will make your life hell.
