问题描述
我只是在学习Rx-java和Rxandroid2，我只是觉得在SubscribeOn和ObserveOn之间的主要区别是什么。
I am just learning Rx-java and Rxandroid2 and I am just confused what is the major difference between in SubscribeOn and ObserveOn.
推荐答案
SubscribeOn指定Observable将在其上运行的Scheduler。
ObserveOn指定观察者将观察此Observable的Scheduler。
SubscribeOn specify the Scheduler on which an Observable will operate.ObserveOn specify the Scheduler on which an observer will observe this Observable.
所以基本上SubscribeOn主要是在后台线程上订阅（执行）（你不想要在等待observable时阻止UI线程）在ObserveOn中你想在主线程上观察结果......
So basically SubscribeOn is mostly subscribed (executed) on a background thread ( you do not want to block the UI thread while waiting for the observable) and also in ObserveOn you want to observe the result on a main thread...
如果你熟悉AsyncTask那么SubscribeOn类似于doInBackground方法和ObserveOn到onPostExecute ......
If you are familiar with AsyncTask then SubscribeOn is similar to doInBackground method and ObserveOn to onPostExecute...
