Tutorial: Adición de un inicio de sesión a una aplicación android mediante la plataforma de identidad de Microsoft

Se aplica a:Círculo verde con un símbolo de marca de verificación blanca. inquilinos de personal Círculo verde con un símbolo de marca de verificación blanca. inquilinos externos (más información)

En este tutorial, agregará lógica de inicio de sesión y cierre de sesión a la aplicación Android. Este código permite a los usuarios iniciar sesión en la aplicación orientada al cliente mediante un inquilino externo o empleador en un inquilino de recursos.

Este tutorial es la parte 2 de la serie de tutoriales de tres partes.

En este tutorial, harás lo siguiente:

  • Adición de lógica de inicio de sesión y cierre de sesión

Prerrequisitos

Inicio de sesión y cierre de sesión de usuarios

Crear y actualizar el fragmento necesario

  1. En app>src>main>java>com.example(nombre de su aplicación). Crea los siguientes fragmentos de Android:

    • OnFragmentInteractionListener
    • SingleAccountModeFragment
  2. Abre OnFragmentInteractionListener.java y reemplaza el código por el siguiente fragmento de código para permitir la comunicación entre distintos fragmentos:

     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 {
     }
    
  3. Abre SingleAccountModeFragment.java y reemplaza el código por el siguiente fragmento de código para inicializar una aplicación de una sola cuenta, carga una cuenta de usuario y obtiene un token para llamar al Graph API de Microsoft:

  4. Para administrar la interfaz de usuario (agregar componentes de interfaz de usuario), abra MainActivity.java y reemplace el código por el siguiente fragmento de código:

Diseño

Un diseño es un archivo que define la estructura visual y la apariencia de una interfaz de usuario, especificando la disposición de los componentes de la interfaz de usuario. Está escrito en XML. Si quiere modelar la interfaz de usuario de este tutorial, se proporcionan los siguientes ejemplos XML:

  1. En app>src>main>res>layout>activity_main.xml. Reemplaza el contenido de activity_main.xml por el siguiente fragmento de código para mostrar botones y cuadros de texto:

     <?xml version="1.0" encoding="utf-8"?>
     <androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:app="http://schemas.android.com/apk/res-auto"
         xmlns:tools="http://schemas.android.com/tools"
         android:id="@+id/drawer_layout"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:fitsSystemWindows="true"
         tools:openDrawer="start">
    
         <include
             layout="@layout/app_bar_main"
             android:layout_width="match_parent"
             android:layout_height="match_parent" />
    
         <com.google.android.material.navigation.NavigationView
             android:id="@+id/nav_view"
             android:layout_width="wrap_content"
             android:layout_height="match_parent"
             android:layout_gravity="start"
             android:fitsSystemWindows="true"
             app:headerLayout="@layout/nav_header_main"
             app:menu="@menu/activity_main_drawer" />
    
     </androidx.drawerlayout.widget.DrawerLayout>
    
  2. En app>src>main>res>layout>app_bar_main.xml. Si no tiene app_bar_main.xml en la carpeta, cree y agregue el siguiente fragmento de código:

    <?xml version="1.0" encoding="utf-8"?>
    <androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity">
    
        <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/AppTheme.AppBarOverlay">
    
            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                app:popupTheme="@style/AppTheme.PopupOverlay" />
    
        </com.google.android.material.appbar.AppBarLayout>
    
        <include layout="@layout/content_main" />
    
    </androidx.coordinatorlayout.widget.CoordinatorLayout>
    
  3. En app>src>main>res>layout>content_main.xml. Si no tiene content_main.xml en la carpeta, cree y agregue el siguiente fragmento de código:

    <?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/content_main"

        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:context=".MainActivity"
        tools:showIn="@layout/app_bar_main">
    
    </androidx.constraintlayout.widget.ConstraintLayout>
    
  4. En app>src>main>res>layout>fragment_m_s_graph_request_wrapper.xml. Si no tiene fragment_m_s_graph_request_wrapper.xml en la carpeta, cree y agregue el siguiente fragmento de código:

    <?xml version="1.0" encoding="utf-8"?>
    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MSGraphRequestWrapper">
    
        <!-- TODO: Update blank fragment layout -->
        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="@string/hello_blank_fragment" />
    
    </FrameLayout>
    
  5. En app>src>main>res>layout>fragment_on_interaction_listener.xml. Si no tiene fragment_on_interaction_listener.xml en la carpeta, cree y agregue el siguiente fragmento de código:

    <?xml version="1.0" encoding="utf-8"?>
    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".OnFragmentInteractionListener">
    
        <!-- TODO: Update blank fragment layout -->
        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="@string/hello_blank_fragment" />
    
    </FrameLayout>
    
  6. En app>src>main>res>layout>fragment_single_account_mode.xml. Si no tiene fragment_single_account_mode.xml en la carpeta, cree y agregue el siguiente fragmento de código:

    <?xml version="1.0" encoding="utf-8"?>
    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
