    static final SingletonF INSTANCE = new SingletonF();
  }

  public static SingletonF getInstance() {
    return SingletonHolder.INSTANCE;
  }

  
  private SingletonF() {}

  public int getInfo_number() {
    return info_number;
  }

  public void setInfo_number(int info_number) {
    this.info_number = info_number;
  }

//  
//  private Object readResolve() {
//    return getInstance();
//  }

}

    @Override
    public void handleMessage(Message msg) {
      switch (msg.what) {
 case 0:
   singletonF = SingletonF.getInstance();
   int first = singletonF.getInfo_number();
   first++;
   Date nowTime = new Date(System.currentTimeMillis());
   SimpleDateFormat sdFormatter = new SimpleDateFormat("HH:mm");
   String retStrFormatNowDate = sdFormatter.format(nowTime);
   singletonF.setInfo_number( first);

   RemoteViews contentViews = new RemoteViews(context1.getPackageName(), R.layout.layout_item);
   // 通过控件的Id设置属性
   contentViews.setImageViewResource(R.id.imageView1, R.mipmap.ic_launcher_round);

PendingIntent.FLAG_CANCEL_CURRENT);

   NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context1)
.setSmallIcon(R.mipmap.ic_launcher_round).setTicker("new message");
   // 自动管理通知栏消息
   mBuilder.setAutoCancel(true);
   mBuilder.setContentIntent(pendingIntent);
   /// 自定义布局
   mBuilder.setContent(contentViews);
   // 使用默认提示音
   mBuilder.setDefaults(Notification.DEFAULT_ALL);
   NotificationManager mNotificationManager = (NotificationManager) context1
.getSystemService(context1.NOTIFICATION_SERVICE);
   // notify(int id, Notification notification)若id为同一个值，则通知栏只会显示一行，并不停更新此消息内容
   // 若为类似UUID.randomUUID().hashCode()这样不同的唯一标识符，则有几条消息通知栏就显示几行
   mNotificationManager.notify(1, mBuilder.build());

   break;

 showNotify();
 btn_number++;
