java - how to display contacts in a listview in Android for Android api 11+ -

i'm sorry if looks same question million times...but google search provides no results, bunch of outdated tutorials using managedquery , other deprecated solutions...

i went through android developer training retrieving contact list, tutorial incomplete , downloading sample code doesn't because sample code more advanced contact list manipulation (search, etc.)

in case, there no reason why there should not simple solution i'm hoping can answer here because i'm sure has been done million times , i'm sure dozens of other beginning android developers appreciate this.

i have followed tutorial best of knowledge no contacts show up. think biggest thing to_ids integer array points android.r.id.text1. i'm confused how supposed somehow pull array of contact names.

also, i'm confused why textview needed when end goal display listview...in tutorial, have mcontactslist list view...but populate list view adapter pointing r.layout.contact_list_item textviews populated to_ids, array of integers.

mcontactslist = (listview) getactivity().findviewbyid(r.layout.contact_list_view); mcursoradapter = new simplecursoradapter(             getactivity(),             r.layout.contact_list_item,             null,             from_columns, to_ids,             0); mcontactlist.setadapter(mcursoradapter); 

what doing wrong , how display contact list in listview?

edit: adding in code:

in fragment class:

public class myfragment extends fragment implements     loadermanager.loadercallbacks<cursor>{  private static final string[] from_columns = {contactscontract.contacts.display_name_primary }; private static final int[] to_ids = {android.r.id.text1}; listview mcontactlist; private simplecursoradapter mcursoradapter;  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate){     return inflater.inflate(r.layout.contact_list_view,container,false); }  @override public void onactivitycreated(bundle savedinstancestate){     super.onactivitycreated(savedinstancestate);     mcontactslist = (listview) getactivity().findviewbyid(r.layout.contact_list_view);     mcursoradapter = new simplecursoradapter(             getactivity(),             r.layout.contact_list_item,             null,             from_columns, to_ids,             0);     mcontactlist.setadapter(mcursoradapter);  }  @override public loader<cursor> oncreateloader(int i, bundle bundle) {     return null; }  @override public void onloadfinished(loader<cursor> cursorloader, cursor cursor) {  }  @override public void onloaderreset(loader<cursor> cursorloader) {  } } 

in activity_main.xml:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <fragment             android:id ="@+id/contactlistfragment"             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="1"             android:name="preamble.myapp.myfragment"/> </linearlayout> 

in contact_list_view xml :

<?xml version="1.0" encoding="utf-8"?> <listview   xmlns:android="http://schemas.android.com/apk/res/android"             android:id="@android:id/list"             android:layout_height="match_parent"             android:layout_width="match_parent"/> 

in contact_list_item xml

<?xml version="1.0" encoding="utf-8"?> <textview xmlns:android="http://schemas.android.com/apk/res/android"             android:id="@android:id/text1"             android:layout_width="match_parent"             android:layout_height="wrap_content"/> 

finally contact_list_layout xml:

what put in contact_list_layout.xml? empty <linearlayout>? it's not clear in tutorial how xml handled. says xml fragment, if it's fragment, why did define listview in contact_list_view.xml?

small stripped down example displaying contacts name in listview. below fragment extends listfragment has default layout. don't need specify own. layout list items taken android's default layouts (android.r.layout.simple_list_item_1) simple single line of text per item.
