//query for the people in your address book 
     cursor = getContentResolver().query(Uri.parse(""+ ContactsContract.CommonDataKinds.Phone.CONTENT_URI), null, null, null,null); 
     startManagingCursor(cursor); 

     //bind the name and the number fields 
     String[] columns = new String[] { ContactsContract.Data.DISPLAY_NAME,ContactsContract.CommonDataKinds.Photo._ID}; 
     int[] to = new int[] { R.id.name_entry, R.id.profile_pic }; 
     mAdapter = new SimpleContactAdapter(this, R.layout.list_entry, cursor, columns, to,mProfileImgIv,mThumbnail); 


mProfileNameAuto.setAdapter(mAdapter);
