電話連絡先から連絡先の写真を取得します。連絡先の写真をどのように進めるべきですか？

Question

私は以下のコードを使用して、連絡先の電話番号と名前にアクセスしています。私はこの機能に連絡先の写真を追加する方法を追加したいと思います。

void loadContacts() { 
    ContentResolver contentResolver=getContentResolver(); 
    Cursor cursor=contentResolver.query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null); 
    if(cursor.getCount() > 0) { 
     while (cursor.moveToNext()) {String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 
      String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
      int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))); 
      if (hasPhoneNumber > 0) { 
       Cursor cursor2 = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
         ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null); 
       while (cursor2.moveToNext()) { 
        String phoneNumber = cursor2.getString(cursor2.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
//make_contact() is a function that takes the contact details and adds them to a list 
//      make_contact(name,phoneNumber); 
       } 
       cursor2.close(); 
      } 
     } 
    } 
    cursor.close(); 
}
