Android ExpandableListView not expanding in Linearlayout

Question

I'm working on a layout but i have problems with two ExpandableListView . I've developed my layout using a lot of LinearLayout, it works but the lists doesn't expand because they doesn't heve the space.Now the lists height is to "fill parent" but if i change it to a number like "200dp" they have the space to expand:

How can I fix this? I don't want to keep a number because when the list is closed remains a white space...That's my xml code:

    <?xml version="1.0" encoding="utf-8"?>

Unfortunately I can't completely answer your question. There's a lot going on there and hard to figure out what is what. Also I'm not entirely sure what you are asking.

However I will point out that you should not embed the ExpandableListViews within the ScrollView . Having a scrollable widget instead another (and having both scroll the same direction) is a big no no and won't work right. You'll see all sorts of problems.

Additionally, your massive LinearLayout solution looks far more complicated then what it needs to be. I'd suggest starting a new question that asks the best way to render this UI. Have it show basically the rectangular boxes of where things should be placed and what part needs to be scrolled. It's critical you layout everything the proper way to avoid these such issues.
