si applica a: tenant della forza lavoro
tenant esterni (scopri di più)
In questa esercitazione si aggiunge la logica di accesso e disconnessione alla tua app Android. Questo codice consente agli utenti di effettuare l'accesso alla vostra app rivolta ai clienti tramite un tenant esterno oppure ai dipendenti tramite un tenant della forza lavoro.
Questa esercitazione è la parte 2 della serie di esercitazioni in 3 parti.
In questa esercitazione, farai:
- Aggiungere la logica di accesso e uscita
Prerequisiti
Effettuare l'accesso e il logout degli utenti
Creare e aggiornare il frammento necessario
Nell'app >src>main>java>com.example(nome della tua app). Creare i frammenti Android seguenti:
- OnFragmentInteractionListener
- SingleAccountModeFragment
Aprire OnFragmentInteractionListener.java e sostituire il codice con il frammento di codice seguente per consentire la comunicazione tra frammenti diversi:
package com.azuresamples.msalandroidapp; /** * This interface must be implemented by activities that contain this * fragment to allow an interaction in this fragment to be communicated * to the activity and potentially other fragments contained in that * activity. * <p> * See the Android Training lesson <a href= * "http://developer.android.com/training/basics/fragments/communicating.html" * >Communicating with Other Fragments</a> for more information. */ public interface OnFragmentInteractionListener { }
