        setContentView(R.layout.activity_main)


//        Retrofit builder
        val retrofitBuilder=Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create())
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create()) // it will convert the retrofit calls into data stream
            .baseUrl("http://worldtimeapi.org")
            .build()

        val timeApi=retrofitBuilder.create(TimeApi::class.java)
        progessbar.visibility=View.VISIBLE




        val time=timeApi.getTime() //this will return our method in interface

        time.subscribeOn(Schedulers.io()) // on rxkotlin thread
            .observeOn(AndroidSchedulers.mainThread())
            .repeatWhen { complete->complete.delay(2,TimeUnit.SECONDS) }   //this function will repeat call
            .subscribe(object:Observer<Time>{ //observer can give result,it can give error also so we will create interface to handle those situation
                override fun onComplete() {
                    Log.e("MainActivity","Completed")
                }

                override fun onSubscribe(d: Disposable) {
                    Log.e("MainActivity","Subscribed")
                }

                override fun onNext(t: Time) {
                    progessbar.visibility=View.INVISIBLE
                    txtTime.text=t.unixtime
                 
                }

                override fun onError(e: Throwable) {
                    Log.e("MainActivity","Error")
                }

            })  
    }
}`

我在AndroidSchedulers.mainThread（）中出错。帮助我克服如果我按alt + enter则建议我创建一个新功能
```
   //    RxKotlin    implementation "io.reactivex.rxjava3:rxkotlin:3.0.0" //    RxAndroid   
```
实现'io.reactivex.rxjava3：rxandroid：3.0.0' //改版实现“ com.squareup.retrofit2：retrofit：2.9.0”实现 “ com.squareup.retrofit2：converter-gson：2.9.0”实现 'com.squareup.retrofit2：adapter-rxjava2：2.6.2'

为什么AndroidSchedulers.mainThread（）给我错误..？
