android - SherlockFragmentList 未定义方法 getLong(int)

Question

我想在操作栏的选项卡上的 SherlockFragmentList 上显示联系人列表。我关注android develop tutorial但是当我尝试在 onItemClick 方法中获取 id 值时出现以下错误:(方法 getLong(int) 未为类型 ContactListFragment 定义)

 public class ContactListFragment extends SherlockListFragment implements LoaderCallbacks<Cursor>,
        AdapterView.OnItemClickListener { 
    @Override
    public void onItemClick(AdapterView<?> parent, View item, int position, long rowID) {
    //Get The Cursor
    Cursor cursor = ((SimpleCursorAdapter) parent.getAdapter()).getCursor();
    //move to the selected contact
    cursor.moveToPosition(position);
    //get the id value
    mContactId = getLong(CONTACT_ID_INDEX);
    mContactKey = getString(LOOKUP_KEY_INDEX);
    mContactUri = Contacts.getLookupUri(mContactId, mcontactKey);

}

这里有什么帮助吗？谢谢

我认为缺少一个光标，另见reference :

Cursor cursor = ((SimpleCursorAdapter) parent.getAdapter()).getCursor();
//move to the selected contact
cursor.moveToPosition(position);
//get the id value
mContactId = cursor.getLong(CONTACT_ID_INDEX);
mContactKey = cursor.getString(LOOKUP_KEY_INDEX);
