I am currently trying to use a ListView inside of a ScrollView. I know from what I\'ve read that this is looked down upon, but I\'m trying to get the ListView to expand com

Answer 1

Attention! Correct way to calculate height is not

params.height = getCount() * (old_count > 0 ? getChildAt(0).getHeight() : 0);

We have to add height of each (minus one) divider heights.

if(oldCount > 0 && getCount() > 0)
    params.height = getCount()
                  * (getChildAt(0).getHeight() + getDividerHeight())
                  - getDividerHeight();
else
    params.height = 0;
