如何从接口中的方法返回类型对象的Observable [英] How to return Observable of type object from a method in the interface

问题描述

我正在学习科特林.如下代码所示，我创建了一个对象模型和一个接口.接口中的方法应返回

I am learning kotlin. as shown in the code below, i created a object Model and an interface. the method in the interface should return

Model.Result

但是当我将上述数据类型包装到Observable中时，出现以下错误

but when I wrap the aforementioned data type in Observable I receive the following error

No type argument expected for class observable

请让我知道如何解决此问题...当我尝试在google中找到一些解决方案但不起作用

please let me know how fix this issue...as i tried to find some solution in google but it does not work

对象:

public object Model {
data class Result(val query: Query)
data class Query(val searchinfo: SearchInfo)
data class SearchInfo(val totalhits: Int)
}

界面:

interface WikiService {
fun method1(): Observable<Model.Result>//No type argument expected for class observable

推荐答案

您正在使用的java.util.Observable不接受任何参数.

You are using java.util.Observable that doesn't accept any paramter.

您应该导入已参数化的io.reactivex.Observable.

You should import io.reactivex.Observable that is parametrized.
