Why Listview Cannot Be Used In A Scrollview?

I found many tutorials and examples butWhy ListView cannot be used in a ScrollView? Only answers is Using a ListView to make it not scroll is extremely expensive and goes against

Solution 1:

The problem is not the ListView but the ScrollView

Those two views need to takes controll of vertical scrolling, if you have a scrollview and a listview in the same layout and the user scroll down, which one have to take the focus and so the scroll?

This is a common problem that has a common and easy solution (this solution comes from Romain Guy from Google Android team!): don't use a listview in a scrollview!

If you want an interesting video/talk you can watch it from Google I/O talks: The world of ListView I really suggest you to take a look :)

Solution 2:

It's because both views are scrollable. Have you already tried to search/google for it? There are thousand matches..

Solution 3:

The ListView has built in capabilities to scroll. You don't need to define it again within a ScrollView

Solution 4:

ListViews are not supposed to get in ScrollView. Even if you hack, and i mean big hack, both views by extending them and got them to scroll , also be itemclickable etc etc , something will break eventually. Also do not add a ListView to a Scroll View.

Solution 5:

I have tested with below xml and it works. But still trying to handle the onTouchEvent function between the ScrollView and ListView. You can Click here to see the original solution.
