EventBus簡單應用

一直都聽說EventBus好用，接觸下來發現真的是簡單易用~

接收的activity：

public class MainActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	//註冊eventbus
        EventBus.getDefault().register(this);
    }
	
    @Override
    protected void onDestroy() {
        //反註冊EventBus
        EventBus.getDefault().unregister(this);
    }
	
	//傳遞過來的參數
    @Subscribe(threadMode = ThreadMode.MAIN)//注意，要寫這個
    public void onEventMainThread(EventBean event) {//名字是自定義的，括號參數是自己寫的bean類
        String msg = event.getMsg();
        Log.e("EventBus", msg);
    }

}

傳遞數據的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傳遞數據
        EventBus.getDefault().post(new EventBean("嘻嘻嘻"));
    }
    }
}

自己寫的一個Bean類：

public class EventBean {

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

}
