android之使用RxJava实现EventBus事件总线

1.引入依赖

//rxjava
implementation 'io.reactivex.rxjava2:rxjava:2.1.7'
implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'

2.RxBus代码

/**
 * 用RxJava实现EventBus
 */
public class RxBus {
    private static RxBus instance;
    private ConcurrentHashMap> subjectMapper=new ConcurrentHashMap<>();

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

    private RxBus(){}

    /**
     * 订阅事件源
     */
    public RxBus onEvent(Observable mObservable, Consumer
