Answer 3

First, why do you want to put a ListView in a ListView ? Maybe your problem can be solved by using an ExpandableListView.

A ListView is a scrollable component and it's not a good idea to nest scrollable components.

If you still want to use nested ListView, you have to know that the calculated height of a ListView is the height of his first element.

So if you want to use a ListView in a ListView, you will have to code a CustomListView and Override some methods as :

• onLayout
• onMeasure
• onDraw / dispatchDraw
