try this code. this stores all the contacts in the ArrayList

ArrayList> contactData=new ArrayList>();
ContentResolver cr = getContentResolver();
 Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
 while (cursor.moveToNext()) {
     try{
     String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 
     String name=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
     String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
     if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
         Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null);
         while (phones.moveToNext()) { 
             String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER));
             HashMap map=new HashMap();
             map.put("name", name);
             map.put("number", phoneNumber);
             contactData.add(map);
         } 
         phones.close(); 
     }
 }catch(Exception e){}
 }

if you want to store the specific contact use the if condition.
