注册事件

if (isEventBus) {
            if (!EventBus.getDefault().isRegistered(this)) {
                EventBus.getDefault().register(this);
            }
        }

注销事件

if (isEventBus) {
            if (EventBus.getDefault().isRegistered(this)) {
                EventBus.getDefault().unregister(this);
            }

发送事件（此处是在设置界面关闭时（onDestroy中）发送事件）

protected void onDestroy() {
        super.onDestroy();
        EventBus.getDefault().post(new TimeEventBean("1"));
    }

定义类TimeEventBean：

public class TimeEventBean {
    private String msg;

    public TimeEventBean() {
    }

    public TimeEventBean(String msg) {
        this.msg = msg;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }
}

接收消息并对其进行处理

@Subscribe(threadMode = ThreadMode.MAIN)
    public void onTimeEvent(TimeEventBean event) {
        //处理主页的event事件
        KLog.d(event.getMsg());
        if (event.getMsg().equals("1")){
            KLog.d("事件1，调用isParentSettingTrue()");
            isParentSettingTrue();
        }
    }
