訊息通知欄的實現

1. 我們要通過builder工廠來建立一個notification的物件
2. 我們建立一個點選了通知欄訊息要跳轉到的activityIntent intent = new Intent(context, PlayActivity.class);
3. 通過builder物件來設定notification相關的屬性值 
   4.我們要獲得notification的管理器通過context.getSystemService(context.NOTIFICATION_SERVICE);得到,由其呼叫notify進行通知

    public static void showNotifictionIcon(Context context) {
        NotificationCompat.Builder
 
 builder = new NotificationCompat.Builder(context);
        Intent intent = new Intent(context, PlayActivity.class);//將要跳轉的介面
        builder.setAutoCancel(true);//點選後消失
        builder.setSmallIcon(R.drawable.icon_music);//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
 
("你好");
        builder.setContentText("今天天氣真好");//通知內容
        builder.setContentTitle("天氣");
        //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);
        NotificationManager manager = (NotificationManager) context.getSystemService
 
(context.NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());
    }另外：

1.  privatevoid showNotification() {  
2.         // TODO Auto-generated method stub
3.         Notification.Builder builder=new Builder(this);  
4.         builder.setSmallIcon(R.drawable.ic_launcher);//設定圖示
5.         builder.setTicker("通知來啦");//手機狀態列的提示
6.         builder.setContentTitle("我是通知標題");//設定標題
7.         builder.setContentText("我是通知內容");//設定通知內容
8.         builder.setWhen(System.currentTimeMillis());//設定通知時間
9.         Intent intent=new Intent(this,MainActivity.class);  
10.         PendingIntent pendingIntent=PendingIntent.getActivity(this, 0, intent, 0);  
11.         builder.setContentIntent(pendingIntent);//點選後的意圖
12.         builder.setDefaults(Notification.DEFAULT_LIGHTS);//設定指示燈
13.         builder.setDefaults(Notification.DEFAULT_SOUND);//設定提示聲音
14.         builder.setDefaults(Notification.DEFAULT_VIBRATE);//設定震動
15.         Notification notification=builder.build();//4.1以上，以下要用getNotification()
16.         manager.notify(Notification_ID, notification);  
17.     }  

1. <uses-permissionandroid:name="android.permission.VIBRATE"/>
2. <uses-permissionandroid:name="android.permission.FLASHLIGHT"/>
