Android Listview Hides Titlebar -

i'm trying make app - has 3 activities. first 2 listviews in linear layouts, , each of them prevents title bar showing up. title bar mean section @ top of activity displays activity's name option setting. third activity not listview, , displays title bar normally, leads me think may problem listviews.

the xml first page is:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" android:orientation="vertical" android:paddingbottom="@dimen/activity_vertical_margin" tools:context=".selectclass">  <listview     android:id="@android:id/list"     android:layout_width="match_parent"     android:layout_height="match_parent"> </listview> 

my java class doesn't display, although set array adapter , onclick listener. if necessary understand what's going on let me know , i'll post them. appreciate or clues. thank you!

edit: first page's java:

package com.example.graeme.dnd5echaracterroller;  import android.app.listactivity; import android.content.intent; import android.os.bundle; import android.view.menu; import android.view.menuitem; import android.widget.adapterview; import android.widget.arrayadapter; import android.widget.linearlayout; import android.view.view; import android.widget.textview;   public class selectclass extends listactivity {  private static string classstring;  public static void setclassstring(string classstring) {     selectclass.classstring = classstring; }  public static string getclassstring() {      return classstring; }  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_select_class);      //initialize available class choices     final string[] classes = {"barbarian","bard","cleric","druid",     "fighter","monk","paladin","ranger","rogue","sorcerer",     "warlock", "wizard"};     arrayadapter<string> classadapter = new arrayadapter<>(getlistview().getcontext(),             r.layout.classlayout, r.id.classname, classes);      getlistview().setadapter(classadapter);      //set on click listener selected class item     adapterview.onitemclicklistener itemclickedhandler = new adapterview.onitemclicklistener(){         public void onitemclick(adapterview<?> parent, view v, int position, long id){             //start new intent headed selectroll, fill class string selected             intent sendclassintent = new intent(selectclass.this, selectroll.class);              //each list item has image, , text             //first grab list item, grab text             linearlayout ll = (linearlayout)v;             textview tv = (textview)(ll).findviewbyid(r.id.classname);             setclassstring((string)(tv.gettext()));              startactivity(sendclassintent);         }     };     getlistview().setonitemclicklistener(itemclickedhandler); }  @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.menu_select_class, menu);     return true; }  @override public boolean onoptionsitemselected(menuitem item) {     // handle action bar item clicks here. action bar     // automatically handle clicks on home/up button, long     // specify parent activity in androidmanifest.xml.     int id = item.getitemid();      //noinspection simplifiableifstatement     if (id == r.id.action_settings) {         return true;     }      return super.onoptionsitemselected(item); } } 

you should modify first activity structure

public class selectclass extends appcompatactivity {     ...     private listview mlistview;     ...      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_select_class);          // initialize lisview         mlistview = (listview) findviewbyid(r.id.lisview_id); // lisview id           //initialize available class choices         final string[] classes = {"barbarian","bard","cleric","druid",         "fighter","monk","paladin","ranger","rogue","sorcerer",         "warlock", "wizard"};         arrayadapter<string> classadapter = new arrayadapter<>  (this,                 r.layout.classlayout, r.id.classname, classes); // update          mlistview.setadapter(classadapter);         ...      }       @override     public boolean oncreateoptionsmenu(menu menu) {        ....     }      @override     public boolean onoptionsitemselected(menuitem item) {         .....     }     } 

and in listview of first activity

<listview android:id="@+id/lisview_id"  // use id initialize listview android:layout_width="match_parent" android:layout_height="match_parent"> 

hope help
