我正在查询parse.com但由于某种原因我无法获得objectId
但是我可以获得其他值。知道为什么我无法检索objectId吗?
我已尝试getObjectId()
以及get("objectId"
)无济于事。
这是一些代码
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dates_main);
ParseQuery<ParseObject> query = ParseQuery.getQuery("Schedule");
query.findInBackground(new FindCallback<ParseObject>() {
@Override
public void done(List<ParseObject> objects, ParseException e) {
if (e == null) {
for (ParseObject object : objects) {
Log.d("App", "object id: " + object.getObjectId());
Log.d("App", "object updated at: " + object.getUpdatedAt());
Log.d("App", "object created at: " + object.getCreatedAt());
}
}
}
});
}
输出:
D/App: object updated at: Sun Oct 11 22:12:38 EDT 2015
D/App: object created at: Sat Oct 10 17:02:43 EDT 2015
D/App: object id:
D/App: object updated at: Sat Dec 19 10:34:38 EST 2015
D/App: object created at: Sat Oct 10 17:11:18 EDT 2015
D/App: object id:
D/App: object updated at: Sun Dec 20 17:37:59 EST 2015
D/App: object created at: Sun Dec 20 17:33:44 EST 2015
D/App: object id:
D/App: object updated at: Thu Jan 07 19:31:05 EST 2016
D/App: object created at: Thu Jan 07 19:30:37 EST 2016
答案 0 :(得分:0)
发现问题。
我的Schedule类中有一个objectId,因为ParseObject已经有了一个objectId,所以它一直引用这个空白
@ParseClassName("Schedule")
public class Schedule extends ParseObject {
String objectId = "";
...
}
需要删除objectId!
