EventBus简单使用

1.导入依赖

implementation 'org.greenrobot:eventbus:3.2.0'

2.创建消息体实体类

public class FirstEvent {
    private String mMsg;

    public FirstEvent(String msg) {
        // TODO Auto-generated constructor stub
        mMsg = msg;
    }
    public String getMsg(){
        return mMsg;
    }
}

3.发送操作

EventBus.getDefault().postSticky(new FirstEvent("返岗"));

4.接收操作

@Override
public void onStart() {
    super.onStart();
    EventBus.getDefault().register(this);
}

@Override
public void onStop() {
    super.onStop();
    EventBus.getDefault().unregister(this);
}

@Subscribe(threadMode = ThreadMode.MAIN, sticky = true)
public void onEventMainThread(FirstEvent event) {
    String msg = "onEventMainThread收到了消息=" + event.getMsg();
    LogImpl.getInstance().e("就收到的=", "" + msg);
    EventBus.getDefault().removeStickyEvent(event);
}
