EventBus下载地址：https://github.com/greenrobot/EventBus

MyEvent:

package com.zzw.testeventbus;public class MyEvent {    public int id;    public String content;        public MyEvent() {        super();            }    @Override    public String toString() {        return "MyEvent [id=" + id + ", content=" + content + "]";    }    }MyEvent

MainActivity：

package com.zzw.testeventbus;import android.app.Activity;import android.content.Intent;import android.graphics.Color;import android.os.Bundle;import android.util.Log;import android.view.View;import android.view.View.OnClickListener;import android.widget.TextView;import de.greenrobot.event.EventBus;public class MainActivity extends Activity {    TextView tv;    public static final String TAG = "MainActivity";    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        tv = (TextView) findViewById(R.id.tv);        EventBus.getDefault().register(this);        findViewById(R.id.bt).setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                Intent intent = new Intent(MainActivity.this, EventService.class);                startService(intent);            }        });    }    // Main线程，这个与Android UI线程密切相关，可以在里面设置UI值，不要阻塞它！    public void onEventMainThread(MyEvent event) {        Log.d(TAG + "--" + "onEventMainThread", event.toString());        tv.setText(event.content);        int id = event.id % 3;        if (id == 0) {            tv.setTextColor(Color.RED);        } else if (id == 1) {            tv.setTextColor(Color.GREEN);        } else if (id == 2) {            tv.setTextColor(Color.BLUE);        }    }    // 后台线程中接收处理    public void onEventBackgroundThread(MyEvent event) {        Log.e(TAG + "--" + "onEventBackgroundThread", event.toString());    }    // 异步线程中接收处理    public void onEventAsync(MyEvent event) {        Log.i(TAG + "--" + "onEventAsync", event.toString());    }    @Override    protected void onDestroy() {        EventBus.getDefault().unregister(this);    }}

EventService:

package com.zzw.testeventbus;import android.app.Service;import android.content.Intent;import android.os.IBinder;import android.os.SystemClock;import de.greenrobot.event.EventBus;public class EventService extends Service {    @Override    public void onCreate() {        super.onCreate();    }    private void task() {        new Thread(new Runnable() {            @Override            public void run() {                for (int i = 1; i <= 100; i++) {                    MyEvent event = new MyEvent();                    event.id = i;                    event.content = "傻逼" + i;                    EventBus.getDefault().post(event);                    SystemClock.sleep(1000);                }            }        }).start();    }    @Override    public int onStartCommand(Intent intent, int flags, int startId) {        task();        return super.onStartCommand(intent, flags, startId);    }    @Override    public void onDestroy() {        super.onDestroy();    }    @Override    public IBinder onBind(Intent intent) {        return null;    }}
