运行效果

使用步骤

1. 在Module的build.gradle添加依赖

compile 'com.squareup:otto:1.3.8'

2. 创建Bus的单例模式

public class MyBus extends Bus{

    private static MyBus sMyBus;

    public static MyBus getInstance() {
        if (sMyBus == null) {
            synchronized (MyBus.class) {
                if (sMyBus == null) {
                    sMyBus = new MyBus();
                }
            }
        }
        return sMyBus;
    }
}

3. 注册和反注册Bus

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //注册到Bus
    MyBus.getInstance().register(this);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    //反注册Bus
    MyBus.getInstance().unregister(this);
}

4. 创建事件

public class MyEvent {
    private String msg;

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

    public String getMsg() {
        return msg;
    }

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

5. 监听事件

/**
 * 默认强制接收事件的方法在主线程执行
 */
@Subscribe
public void onEvent(MyEvent event) {
    Toast.makeText(this, event.getMsg(), Toast.LENGTH_SHORT).show();
}

6. 发布事件

public void onPublishEvent(View view) {
    MyBus.getInstance().post(new MyEvent("Hello Bus"));
}
