訊息推送接收到後，顯示通知欄

    public static void showNotifictionIcon(Context context) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        Intent intent = new Intent(context, XXXActivity.class);//將要跳轉的介面
        //Intent intent = new Intent();//只顯示通知，無頁面跳轉
        builder.setAutoCancel(true
 
);//點選後消失
        builder.setSmallIcon(R.drawable.app_icon);//設定通知欄訊息標題的頭像
        builder.setDefaults(NotificationCompat.DEFAULT_SOUND);//設定通知鈴聲
        builder.setTicker("狀態列顯示的文字");
        builder.setContentTitle("標題");
        builder.setContentText("通知內容");
        //利用PendingIntent來包裝我們的intent物件,使其延遲跳轉
 

        PendingIntent intentPend = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
        builder.setContentIntent(intentPend);
