ScrollView and Wrap_Content not work

Question

I have a problem in my xml, the ScrollView does not work when my RelativeLayout is wrap_content, but if I have a larger screen than the fixed height works correctly, but if I have a larger fixed height than screen the works correctly, but I need to be wrap_content, because I have a listview that is populated gradually as client wants, follows the xml

My listview are configured to not scroll, through code

That as the relative layout increases and passes the size of the screen the scrollview not opens scrolling. Sorry for not specifying — Gabriel Santos, Jun 06 '14 at 12:30
Have a look at this question: http://stackoverflow.com/questions/18367522/android-list-view-inside-a-scroll-view Also why did you set `android:layout_width="0dp"` and put two extra LinearLayout before and after the ScrollView? — Rafi Kamal, Jun 06 '14 at 12:37
For create a margin, i am a newbie in android, was the way I found, do you think this way? — Gabriel Santos, Jun 06 '14 at 12:58
@RafiKamal your coment was very useful, might want to put it as a response, so I choice — Gabriel Santos, Jun 06 '14 at 13:59

try do define ScrollView layout_width and layout_height as match_parent, without layout_weight

by the way, you should not mix ScrollView with ListView since both have his own scroll. I suggest to split it like:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        (...)
    </ScrollView>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <ListView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
        </ListView>

    </LinearLayout>

But i need a margin, match_parent occupy all the space in the horizontal orientation, and notwithstanding don't work – Gabriel Santos Jun 06 '14 at 12:47
in this case the listview not disappears when stay big? – Gabriel Santos Jun 06 '14 at 13:01
in this case you have 2 separated things: -all stuff inside scrollView have his own scroll (if needed), AND everthing inside listView. -ListView will disappear only if have no data inside ofcourse (wrap content) – PedroHawk Jun 06 '14 at 13:07
I do not wish it had more of a scroll, wish that functioned as a kind of gridview, a simple list, it not need a scroll it, just scroll the page. is it possible? or i try other way? – Gabriel Santos Jun 06 '14 at 13:16
Understand that ScrollView have is own scroll properties and listView others. Thats why you shouldnt mix it up. – PedroHawk Jun 06 '14 at 13:38
The porpose of listView is to load data and become scrollable on that determinated space; ScrollView its all about scrolling whats inside it (can be full page) – PedroHawk Jun 06 '14 at 13:45

ScrollView and Wrap_Content not work
