RxJava回调线程切换

最近又在做环信,他的异步回调在子线程中,用起来不是很好用,恰好项目中用了RxJava就用RxJava来做一下线程切换吧.

public class MyEmProxy<T> implements EMValueCallBack<T> {
    private Action1<T> action1;
    private Action1<Throwable> action2;


    public MyEmProxy(Action1<T> action1) {
        this.action1 = action1;
    }


    public MyEmProxy(Action1<T> action1, Action1<Throwable> action2) {
        this.action1 = action1;
        this.action2 = action2;
    }


    @Override
    public void onSuccess(final T t) {
        Observable.create(new Observable.OnSubscribe<T>() {
            @Override
            public void call(Subscriber<? super T> subscriber) {
                subscriber.onNext(t);
                subscriber.onCompleted();
            }
        }).subscribeOn(Schedulers.trampoline()).unsubscribeOn(Schedulers.trampoline())
                  .observeOn(AndroidSchedulers.mainThread()).subscribe(action1);
    }


    @Override
    public void onError(final int i, final String s) {
        if (action1 != null && action2 != null) {
            Observable.create(new Observable.OnSubscribe<T>() {
                @Override
                public void call(Subscriber<? super T> subscriber) {
                    subscriber.onError(new MyEMException(s, i));
                }
            }).subscribeOn(Schedulers.trampoline()).unsubscribeOn(Schedulers.trampoline())
                      .observeOn(AndroidSchedulers.mainThread()).subscribe(action1, action2);
        }
    }
}

使用:

 

EMClient.getInstance().groupManager().asyncGetJoinedGroupsFromServer(new MyEmProxy<>(new Action1<List<EMGroup>>() {
            @Override
            public void call(List<EMGroup> emGroups) {
                Log.i(TAG, "onSuccess: " + Thread.currentThread().getName());
                initRv();
                emptyLayout.showSuccess();
            }
        }, new Action1<Throwable>() {
            @Override
            public void call(Throwable throwable) {
                emptyLayout.showError();
            }
        }));

其他的子线程回调应该也可以这样来做的.
