public class MyService extends Service {

public static final String TAG = "MyService";

private MyBinder mBinder = new MyBinder();

@Override
    public void onCreate() {
        super.onCreate();
        Notification notification = new Notification(R.drawable.ic_launcher,
                "有通知到来", System.currentTimeMillis());
        Intent notificationIntent = new Intent(this, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);
        notification.setLatestEventInfo(this, "这是通知的标题", "这是通知的内容",
                pendingIntent);
        startForeground(1, notification);
        Log.d(TAG, "onCreate() executed");
    }

.........

}

我们首先创建了一个Notification对象,然后调用了它的setLatestEventInfo()方法来为通知初始化布局和数据,并在这里设置 了点击通知后就打开MainActivity。然后调用startForeground()方法就可以让MyService变成一个前台Service, 并会将通知的图片显示出来。
