ListView android: I can't see my list items -

i'm trying show listview in android application. (i know i'm not extending of listactivity, can error?) code:

public class home extends activity{     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_home);          startlocation();         createmenutabs();          final string[] datos = new string[]{"lista 1","lista 2","lista 3","lista 4","lista 5"};          arrayadapter<string> adaptador = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, datos);         listview urban_lines_list = (listview)findviewbyid(r.id.urban_lines_list);         urban_lines_list.setadapter(adaptador);     } } 

the xml is:

 <linearlayout android:id="@+id/urbano"       android:orientation="vertical"       android:layout_width="match_parent"       android:layout_height="match_parent" >       <textview android:id="@+id/urban_lines"           android:layout_width="match_parent"           android:layout_height="match_parent"           android:text="@string/list_of_lines"/>       <listview android:id="@+id/urban_lines_list"           android:layout_width="match_parent"           android:layout_height="match_parent"/>  </linearlayout> 

thanks help!

your textview filling whole screen, change height wrap_content.

<textview android:id="@+id/urban_lines"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:text="@string/list_of_lines"/>
