AndroidSchedulers的mainThread()无法切换到主线程

1
Observable.create(new Observable.OnSubscribe<Integer>() {
2
                   @Override
3
                   public void call(Subscriber<? super Integer> subscriber) {
4
                        for (int i=0;i<10;i++){
5
                            subscriber.onNext(i);
6
                        }
7
                       subscriber.onCompleted();
8
                   }
9
               })
10
                       .subscribeOn(Schedulers.io())
11
                       .subscribeOn(AndroidSchedulers.mainThread())//这里原来是要切换到主线程运行的
12
                       .subscribe(new Observer<Integer>() {
13
                   @Override
14
                   public void onCompleted() {
15
                       Log.i(MainActivity.class.getSimpleName(),"onCompleted");
16
                   }
17

18
                   @Override
19
                   public void onError(Throwable e) {
20
                       Log.i(MainActivity.class.getSimpleName(),"onError");
21
                   }
22

23
                   @Override
24
                   public void onNext(Integer i) {
25
                       Log.i(MainActivity.class.getSimpleName(),i+"");
26
                   }
27
               });
28
            }
29
        });

上面这段代码一直报，只有主线程才能更新View

Only the original thread that created a view hierarchy can touch its views.

可能有人发现了错误，细节啊

1
 .subscribeOn(AndroidSchedulers.mainThread())

上面的这段代码“subscribeOn()”这个方法是设定Observable所在线程，所以，是将Observable切换到主线程了

正确的应该是调用”observeOn()“方法

1
  .observeOn(AndroidSchedulers.mainThread())
