新增依賴:

implementation 'io.reactivex.rxjava2:rxandroid:2.0.2'
implementation 'io.reactivex.rxjava2:rxjava:2.x.y'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'//轉換器，請求結果轉換成Model
implementation 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'//配合Rxjava 使用

介面:

public interface JavaBeanService {
    
    @GET("dish_list.php?stage_id=1&limit=20&page=1")
    Observable<JavaBean> getResult();
}

                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
