RxBus的工具类

• 直接上代码 ，三个类

import rx.Observable;
import rx.functions.Func1;
import rx.subjects.PublishSubject;
import rx.subjects.SerializedSubject;
import rx.subjects.Subject;

/**
 * @author xzj
 * @date 2016/8/24 14:00.
 */
public class RxBus {
    private static RxBus mRxBus = null;
    /**
     * PublishSubject只会把在订阅发生的时间点之后来自原始Observable的数据发射给观察者
     */

    private Subject mRxBusObserverable = new SerializedSubject<>(PublishSubject.create());

    public static synchronized RxBus getInstance() {
        if (mRxBus == null) {
            mRxBus = new RxBus();
        }
        return mRxBus;
    }

    public void send(Object o, String tag) {
        mRxBusObserverable.onNext(new RxBusObject(tag, o));
    }

//    public Observable
