Rxjava处理线程切换问题

Rxjava处理线程切换问题

1.新建一个Lifecycle类继承ObservableTransformer

/**
 * 线程切换
 * @param <T>
 */
public class SchedulerTransformer<T> implements ObservableTransformer<T,T> {
    @NotNull
    @Override
    public ObservableSource<T> apply(@NotNull Observable<T> upstream) {
        return upstream.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread());
    }
}

2.配合compose()

Observable.create(...)
    .compose(new SchedulerTransformer<>())...
