通过通知的Android意图不保留额外数据

Question

我正在尝试通过存储在通知中的意图传递字符串。 但是当我从新片段中的意图中获取字符串时，它是一个空值，它给了我一个 NullPointerException。

创建通知的代码（在活动A中片段A的方法A中）

Notification.Builder mBuilder = new Notification.Builder(getActivity().getBaseContext());
        mBuilder.setContentTitle("My first notification");
        mBuilder.setContentText("Click to see the details...");
        mBuilder.setSmallIcon(R.drawable.ic_launcher);

        //Intent maken voor notification
        Intent intentVoorNotificatie = new Intent(getActivity(), activity_detail_notification.class);
        EditText edTekst = (EditText) getActivity().findViewById(R.id.etTekst);


        String strTekstNotificatie = edTekst.getText().toString();
        intentVoorNotificatie.putExtra("detailNotificatie", strTekstNotificatie);


        //Intent naar PendingIntent converteren
        PendingIntent pIntentVootNotificatie = PendingIntent.getActivity(getActivity().getBaseContext(),
                                                0, intentVoorNotificatie, PendingIntent.FLAG_ONE_SHOT);
        mBuilder.setContentIntent(pIntentVootNotificatie);

        //Notificatie tonen
        NotificationManager mNotificationManager = (NotificationManager) getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1,mBuilder.build());

活动B中片段B的方法A

//Haal doorgegeven tekst uit intent
    Intent intent = getActivity().getIntent();
    String strTekst = intent.getStringExtra("detailNotificatie");

    TextView tvTekst = (TextView) getActivity().findViewById(R.id.tvDetailVanNotificatie);
    tvTekst.setText(strTekst);

我在 setText() 方法上得到了 nullPointer，因为从意图中提取它时字符串为空。

我是否做错了什么导致数据丢失或消失？

尝试更改此代码`

 PendingIntent pIntentVootNotificatie = PendingIntent.getActivity(getActivity().getBaseContext(),
                                                0, intentVoorNotificatie, PendingIntent.FLAG_ONE_SHOT);

到这个`

PendingIntent pIntentVootNotificatie = PendingIntent.getActivity(getActivity().getBaseContext(),
                                                0, intentVoorNotificatie, PendingIntent.FLAG_UPDATE_CURRENT);
