Android通知点击打开错误的片段

Question

我遇到的问题是，单击通知会使我陷入错误的片段中。

这是详细的问题- 点击通知-> intent.getStringExtra("id")被困在我的onCreate()的MainActivity中。

在这里，我说转到具有2个传呼机（子片段）的片段B，分别说C和D。

所以B处理了所需的片段D的打开，我可以看到片段D打开了1秒钟，但它跳回到了片段A，这是我的家庭片段。

这是我的MainActivity.java代码-

if (getIntent().getStringExtra("id") != null) {

    String id = getIntent().getStringExtra("id");


    if (id == null) {
        getSupportFragmentManager().beginTransaction().replace(R.id.frag, new FragA()).addToBackStack(null).commit();
    } else {
        Fragment fragment = new FragB();
        Bundle bundle = new Bundle();
        bundle.putString("id", id);
        fragment.setArguments(bundle);
        getSupportFragmentManager().beginTransaction().replace(R.id.container, fragment).addToBackStack(null).commit();
    }
}

这是我的通知代码-

Notification buildNotification(final String id) {
    Intent notificationIntent = new Intent(this.context, MainActivity.class);
    notificationIntent.putExtra("id", id);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
    stackBuilder.addParentStack(MainActivity.class);
    stackBuilder.addNextIntent(notificationIntent);

    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(100, PendingIntent.FLAG_UPDATE_CURRENT);
    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    return new NotificationCompat.Builder(this.context, "channel_id")
          .setContentTitle("Title")
          .setContentText("Message")
          .setSmallIcon(R.drawable.icon)
          .setAutoCancel(true)
          .setContentIntent(resultPendingIntent)
          .build();
 }

    private class NotificationReceiver extends BroadcastReceiver {

            @Override
            public void onReceive(Context ctx, Intent intent) {

                NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

                String id = intent.getStringExtra("id");
                if (notificationManager != null) {
                  Notification notification = buildNotification(id);
                    if (notification != null) {
                         notificationManager.notify(100, notification);
                    }

                }

            }

     }
