RxBus实现

1 添加Gradle:

//RxAndroidcompile 'io.reactivex.rxjava2:rxandroid:2.0.1'compile 'io.reactivex.rxjava2:rxjava:2.0.4'

2 添加RxBus类:

public class RxBus {private static volatile RxBus mInstance;private final Subject<Object> subject = PublishSubject.create().toSerialized();private Disposable dispoable;private RxBus() {}public static RxBus getInstance() {    if (mInstance == null) {        synchronized (RxBus.class) {            if (mInstance == null) {                mInstance = new RxBus();            }        }    }    return mInstance;}/** * 发送事件 * @param object */public void send(Object object) {    subject.onNext(object);}/** * @param classType * @param <T> * @return */public <T> Observable<T> toObservale(Class<T> classType) {    return subject.ofType(classType);}/** * 订阅 * @param bean * @param consumer */public void subscribe(Class bean, Consumer consumer) {    dispoable = toObservale(bean).subscribe(consumer);}/** * 取消订阅 */public void unSubcribe(){    if (dispoable != null && dispoable.isDisposed()){        dispoable.dispose();    }}}

3 添加监听

RxBus.getInstance().subscribe(String.class, new Consumer<String>() {        @Override        public void accept(String path) throws Exception {                                } });

4 发送监听事件：

RxBus.getInstance().send("发送事件");

5 在退出Activity(Fragment)时,取消监听:

RxBus.getInstance().unSubcribe();
