通知サービスを介して ServicesActivity.java から NotificationView.java にデータを渡すのが好きです。しかし、データの受け渡しは最初は正しく、別のデータを送信すると、以前のデータは更新されません。ご覧のとおり、以下の logcat 出力は、最初に 2 つのデータを通知に送信し、それを出力します。 NotificationView.java で渡されても問題ありません。その後、3 つのデータを再送信しますが、NotificationView.java での出力は 2 つのデータのままです。通知に送信したデータの数が何であれ、 NotificationView.java での出力は最初の出力に従います。logcat の出力は次のとおりです。
11-21 10:42:03.645: D/String(25694): admin,admin
11-21 10:42:33.645: D/String(25694): admin,admin,admin
11-21 10:42:06.308: D/how(25694): admin,admin
11-21 10:42:36.518: D/how(25694): admin,admin
**Log.d("String",str) は ServicesActivity.java の displayNotification() にあり、Log.d("how",i) は NotificationView.java にあります。
