 private ArrayList<Map<String, String>> peopleList;
 private AutoCompleteTextView txtPhoneName;
    private SimpleAdapter mAdapter;

//in oncreate

 txtPhoneName=(AutoCompleteTextView)findViewById(R.id.autoDeni);

peopleList = new ArrayList<Map<String, String>>();
PopulatePeopleList();


mAdapter = new SimpleAdapter(this, peopleList, R.layout.row ,new String[] { "Name", "Phone"  }, new int[] { R.id.text1, R.id.text2  });

txtPhoneName.setAdapter(mAdapter);

 public void PopulatePeopleList()
  {

 peopleList.clear();

Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while (people.moveToNext())
{
String contactName = people.getString(people.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

String contactId = people.getString(people.getColumnIndex(ContactsContract.Contacts._ID));
String hasPhone = people.getString(people.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

if ((Integer.parseInt(hasPhone) > 0))
{

// You know have the number so now query it like this
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
while (phones.moveToNext()) {

//store numbers and display a dialog letting the user select which.
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

//String numberType = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));

Map<String, String> mapa = new HashMap<String, String>();

mapa.put("Name",contactName+"\n"+phoneNumber);
mapa.put("Phone", phoneNumber);

/* if(numberType.equals("0"))
mapa.put("Type", "Work");
else
if(numberType.equals("1"))
mapa.put("Type", "Home");
else if(numberType.equals("2"))
mapa.put("Type",  "Mobile");
else
mapa.put("Type", "Other");*/

//Then add this map to the list.
peopleList.add(mapa);
}
phones.close();
}
}
people.close();

startManagingCursor(people);
}

//this is what i get for getting all the contacts in the autocompletetextview here i will show u the row.xml that i am using in the simple adapter NOTE:in oncreate the current context IS NOT row.xml

row xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
 <TextView 
android:id="@+id/text1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:padding="10dip" >


</TextView>

<TextView 
android:id="@+id/text2"
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:padding="10dip" >


</TextView>
