Question

考虑这个func1（）在另一个Java类中，您可以通过回调到达它。我的问题是我想等待func1结果。我该怎么办？

launch{
    func1()

    func2()
    func3()

    // I want to catch the data here, so it should wait here but because of using rxjava (another thread), I cannot control it. 
    // I know if I use new retrofit libs, I can use coroutines, but right now, I cannot change old ones. 

    //My problem is I want to wait the func1 result here. How can I do that?
}

suspend fun func2(){}
suspend fun func3(){}

//Another java class
public Single<MyData> func1(){
    apiClient.getMyData()
    .subscribe(myData -> {
        // Let's say this takes 5 seconds to get the data
    }, throwable -> {

    });
}

添加库

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-rx2:$coroutine_version"

然后拨打电话

func1().await()
