你必须在实例化它之前注册这个 ParseObject 子类 [英] You must register this ParseObject subclass before instantiating it
问题描述
我在使用 Parse
的 Android
应用程序中遇到以下错误:
I am getting the following error in my Android
application using Parse
:
你必须在实例化之前注册这个 ParseObject 子类.
在我的 Application
对象中,我在 onCreate
中执行以下操作:
In my Application
object, I am doing the following inside onCreate
:
Parse.enableLocalDatastore(this);
Parse.initialize(this, "code", "code");
那为什么我仍然收到这个错误?昨天还好好的,但是突然就不行了.
So why am I still getting this error? It was working fine yesterday but it's all of a sudden stopped working.
这是我的清单文件:
<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
....
LogCat:
java.lang.IllegalArgumentException: You must register this ParseObject subclass before instantiating it.

推荐答案
您必须致电ParseObject.registerSubclass(YourClassName.class);
打电话之前Parse.initialize()
.
You must call
ParseObject.registerSubclass(YourClassName.class);
before calling
Parse.initialize()
.
另外,你需要像这样注释你的自定义类:
In addition, you need to annotate your custom class like this:
@ParseClassName("YourClassName")
public class YourClassName extends ParseObject
{
}
最后,您的自定义类需要一个默认的无参数构造函数,以便由 ParseObject
注册.
Finally, your custom class needs a default no-args constructor in order to be registered by ParseObject
.
