我可以找到一种方法从我的通知中向我的活动发送参数.

我有一个创建通知的服务.当用户点击通知时,我想用一些特殊参数打开我的主要活动.例如项目ID,因此我的活动可以加载并呈现特殊项目详细信息视图.更具体地说,我正在下载一个文件,当下载文件时,我希望通知有一个意图,当点击它时,它会以特殊模式打开我的活动.我试图使用putExtra我的意图,但似乎无法提取它,所以我认为我做错了.

我的服务中创建通知的代码:

        // construct the Notification object.
     final Notification notif = new Notification(R.drawable.icon, tickerText, System.currentTimeMillis());


    final RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
    contentView.setImageViewResource(R.id.image, R.drawable.icon);
    contentView.setTextViewText(R.id.text, tickerText);
    contentView.setProgressBar(R.id.progress,100,0, false);
    notif.contentView = contentView;        

    Intent notificationIntent = new Intent(context, Main.class);
    notificationIntent.putExtra("item_id", "1001"); // <-- HERE I PUT THE EXTRA VALUE
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notif.contentIntent = contentIntent;

    nm.notify(id, notif);

我的Activity中的代码尝试从通知中获取额外参数:

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);


    Bundle extras = getIntent().getExtras();
    if(extras != null){
        Log.i( "dd","Extra:" + …

嗨我想在一个视图中显示所有通知..并想要更新状态栏中的通知数...它更新所有信息但显示数字始终为1 ..请告诉我如何解决它...

@Override
public void onReceive(Context context, Intent intent)
{
    //Random randGen = new Random();
    //int notify_id = randGen.nextInt();
    NotificationManager notificationManager = (NotificationManager)
        context.getSystemService(Activity.NOTIFICATION_SERVICE);
    String title = intent.getStringExtra(TableUtils.KEY_TITLE);
    String occasion = intent.getStringExtra(TableUtils.KEY_OCCASION);
    Notification notification = 
        new Notification(R.drawable.icon, "Love Cardz" , 
                         System.currentTimeMillis());
    // notification.vibrate = new long[]{100,250,300,330,390,420,500};
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.number+=1;
    Intent intent1 = new Intent(context, ThemesBrowserActivity.class);
    PendingIntent activity = 
        PendingIntent.getActivity(context, 1 , intent1, 
                                  PendingIntent.FLAG_UPDATE_CURRENT);
    notification.setLatestEventInfo(context, occasion, title, activity);
    notificationManager.notify(1, notification);
}
