EventBus简单应用

一直都听说EventBus好用，接触下来发现真的是简单易用~

接收的activity：

public class MainActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	//注册eventbus
        EventBus.getDefault().register(this);
    }
	
    @Override
    protected void onDestroy() {
        //反注册EventBus
        EventBus.getDefault().unregister(this);
    }
	
	//传递过来的参数
    @Subscribe(threadMode = ThreadMode.MAIN)//注意，要写这个
    public void onEventMainThread(EventBean event) {//名字是自定义的，括号参数是自己写的bean类
        String msg = event.getMsg();
        Log.e("EventBus", msg);
    }

}

传递数据的activity：

public class Main2Activity extends Activity {

	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
	}
	 public void onClick(View v) {
		//Eventbus传递数据
        EventBus.getDefault().post(new EventBean("嘻嘻嘻"));
    }
    }
}

自己写的一个Bean类：

public class EventBean {

    private String mMsg;
    public EventBean(String msg) {
        mMsg = msg;
    }
    public String getMsg(){
        return mMsg;
    }

}
