Question
First the listview is GONE then it goes VISIBLE when i click a button but im having this error only in Mobile Devices with Android 3.1 the listview not showing. I try with the cachecolorhint #00000000 but its not working. Im currently developing with Xamarin.
Error Image: http://i471.photobucket.com/albums/rr77/lithium1818/Android_20140924.png
C# Code:
public void VisibilidadBloqueResultado(bool visible)
{
resultado.Visibility = visible == true ? ViewStates.Visible : ViewStates.Gone;
}
After I set the listVisible I set de Adapter
adapter = new ListVisitaEmpresasAdapter(atx1, lista);
empresas.Adapter = adapter;
empresas.ItemClick += empresas_ItemClick;

I just move the LinearLayout of the list before the ScrollView and it works perfect here is the Final XML.
XML Code:
<?xml version="1.0" encoding="utf-8"?>

p1:paddingRight="5dip"
p1:paddingBottom="5dip"
p1:paddingLeft="5dip">
