设置了notitification的图标（可以用于测试Android Studio中默认的图标），并确保您的按钮的onClick方法名称即test1的（）是相同名称的设定在按钮的属性属性中。

NotificationCompat.Builder mBuilder = 
     new NotificationCompat.Builder(this) 
       .setContentTitle("My notification") 
       .setContentText("Hello World!"); 
       .setSmallIcon(R.drawable.cast_ic_notification_0)
