Question

为什么Intent来自通知无效？

Intent resultIntent = new Intent(context, myclass.class);
        resultIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        Bundle extras=new Bundle();
        extras.putString("key","value");
        PendingIntent resultPendingIntent =
                PendingIntent.getActivity(
                        context,
                        0,
                        resultIntent,
                        PendingIntent.FLAG_UPDATE_CURRENT
                );
            NotificationCompat.Builder n = new NotificationCompat.Builder(context)
                    .setContentTitle("test")
                    .setContentText(text)
                    .setSound(sound)
                    .setContentIntent(resultPendingIntent)
                    .setAutoCancel(true)
                    .setExtras(extras)
                    .setSmallIcon(android.R.drawable.ic_media_play);
            NotificationManager notificationManager = (NotificationManager) context.getSystemService((context.getApplicationContext().NOTIFICATION_SERVICE));
            notificationManager.notify(0, n.build());
    }

但是在myclass的onStart()中，当我调用getintent().getExtras()时，结果是 null ，为什么？我怎样才能getExtras()通知Intent？

Answer 1

我想你忘记打电话了。

resultIntent.putExtras(extras);

在打电话之前。

Answer 2

这对我有用，你可以从中得到想法：

 Intent notificationClickIntent = new Intent(context, NotificationAppListing.class);
            notificationClickIntent.putExtra("notificationType", notificationTypeOne);
            notificationClickIntent.putExtra("notificationUrl", notificationUrl);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(Search.class);
        stackBuilder.addNextIntent(notificationClickIntent);
        PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
        notificationBuilder.setContentIntent(pendingIntent);
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(mId, notificationBuilder.build());

Answer 3

你应该将你的额外内容添加到resultIntent，而不是NotificationCompat.Builder（而不是resultPendingIntent）

Bundle extras=new Bundle();
extras.putString("key","value");
resultIntent.putExtras(bundle);

或简单地说：

resultIntent.putExtra("key","value");

Answer 4

你需要放置

resultIntent.putExtras(bundle)

在捆绑后分配键值对
那么你可以得到值

Bundle extras = getIntent().getExtras();
if (extras != null) {
String yourValue = extras.getString("key");    
}

我如何通知通知？
