com.parse.ParseObject无法转换为 [英] com.parse.ParseObject cannot be cast to

问题描述

我正在开发具有解析平台的应用程序.要获取数据，我正在调用ParseCloud.callFunctionInBackground函数.

I am developing application which having Parse Platform. To fetch data I am calling ParseCloud.callFunctionInBackground function.

我已经将解析及其子类注册到Application类中，如下所示:

I have registered the Parse and its sub class into the Application class like below :

public class App extends Application {
    @Override
    public void onCreate(){
        super.onCreate();
        Parse.setLogLevel(Parse.LOG_LEVEL_VERBOSE);    
        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        builder.networkInterceptors().add(httpLoggingInterceptor);    
        ParseObject.registerSubclass(ParseMessage.class);
        Parse.initialize(new Parse.Configuration.Builder(this)
                        .applicationId("KEY")
                        .server("URL")
                        .build());
    }
}

我在下面的模型类中扩展了ParseObject:

I have below model class which extends ParseObject :

@ParseClassName("ParseMessage")
public class ParseMessage extends ParseObject {

    // Ensure that your subclass has a public default constructor
    public ParseMessage() {
        super();
    }

    public ParsePhoto getPhotos() {
        return (ParsePhoto) getParseObject("photos");
    }

    public void setPhotos(ParsePhoto value) {
        put("photos", value);
    }

    public String getCaption() {
        return getString("caption");
    }

    public void setCaption(String value) {
        put("caption", value);
    }

}

当我从片段中调用以下方法时:

When I calling this below method from my Fragment :

HashMap<String, Object> params = new HashMap<String, Object>();
ParseCloud.callFunctionInBackground("MY_METHOD", params, new FunctionCallback<ArrayList<ParseMessage>>() {
            public void done(ArrayList<ParseMessage> mapObject, ParseException e) {
                if (e == null) {
                    ParseMessage object = mapObject.get(i);
                    }
                } else {
                }
    }
});

但是我遇到了以下异常:

But I am getting below exception :

java.lang.ClassCastException:com.parse.ParseObject无法转换为 com.example.ParseMessage

java.lang.ClassCastException: com.parse.ParseObject cannot be cast to com.example.ParseMessage

我已经在Google和Stackoverflow上搜索了很多产品，但没有得到任何解决方案.谁能帮我解决这个问题，因为我已经花了很多时间了.下面是我从Parse得到的响应:

I already searched lots of thins from Google and Stackoverflow, but I did not get any solutions of it. Can anyone help me into this as I already spend a lot of time on this. Below response which I am getting from Parse :

推荐答案

您提供的信息不是很具体，但是从调试器屏幕上看，您似乎正在尝试将ParsePhoto转换为ParseMessage. ParsePhoto是ParseObject的子类，我相信这是造成此问题的原因.

The info you have provided is not very concrete, but from the debugger screen, it looks like you are trying to convert ParsePhoto into ParseMessage. ParsePhoto is subclass of ParseObject, and I believe this is causing the issue.
