'ScrollView and Wrap_Content not work
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
Solution 1:[1]
Is the listviewinside the scrollview working??
I think the real problem is this.
A listview inside a Scrollview is not a good practice.
Listview will try to implement its own scrolling. But the parent Scrollview will take up all the gestures. So Listview cannot be a child of a Scrollview.
if you still want it to be done that way.
Try this.
ListView lv = (ListView)findViewById(R.id.myListView); // your listview inside scrollview
lv.setOnTouchListener(new ListView.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
// Handle ListView touch events.
v.onTouchEvent(event);
return true;
}
});

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>
