如何在android studio应用程序中显示谷歌帐户信息

如何解决如何在android studio应用程序中显示谷歌帐户信息

我正在用 java 在 android studio 中开发一个应用程序。目前我的应用程序有 3 个重要文件： 1.loggin.class：它是一个主登录窗口，用户可以通过谷歌注册到应用程序 2.main.class：包含一个导航抽屉，还允许您通过选择抽屉中的任何选项来更改片段。 3.perfil_user.class：这是一个包含用户配置文件视图的片段，应用程序在注册或点击谷歌按钮后将您重定向到该视图。 除了一个小细节，一切都完美无缺，当我按下谷歌按钮时，我希望捕获邮件、个人资料图片和用户名值，以便它们显示在用户个人资料视图中，不幸的是这不会发生，我会因为我是 android studio 的新手，所以希望看到你们中的一个可以帮助我的选项，我在下面留下我的预览：

main.class

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
    DrawerLayout drawerLayout;
    ActionBarDrawerToggle actionBarDrawerToggle;
    Toolbar toolbar;
    NavigationView navigationView;
    //variables para cargar el fragment
    FragmentManager fragmentManager;
    FragmentTransaction fragmentTransaction;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar=findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);//se pasa el toolbar
        drawerLayout=findViewById(R.id.drawer);
        navigationView=findViewById(R.id.navigationView);
        navigationView.setNavigationItemSelectedListener(this);
        actionBarDrawerToggle=new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.open,R.string.close);
        drawerLayout.addDrawerListener(actionBarDrawerToggle);
        actionBarDrawerToggle.setDrawerIndicatorEnabled(true);
        actionBarDrawerToggle.syncState();
        //cargar fragment principal
        FragmentManager fragmentManager;
        FragmentTransaction fragmentTransaction;
        fragmentManager=getSupportFragmentManager();
        fragmentTransaction=fragmentManager.beginTransaction();
        fragmentTransaction.add(R.id.container,new perfil_user());
        fragmentTransaction.commit();


    }


    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        if (item.getItemId() == R.id.user){
            FragmentManager fragmentManager;
            FragmentTransaction fragmentTransaction;
            fragmentManager=getSupportFragmentManager();
            fragmentTransaction=fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.container,new perfil_user());
            fragmentTransaction.commit();

        }
        else if (item.getItemId() == R.id.exit){
            finish();
        }
        //aquí van las otros fragment
        drawerLayout.closeDrawer(GravityCompat.START);
        return false;
    }
}

登录.class

public class loggin extends AppCompatActivity {
    //variables google
    Button register;
    SignInButton signInButton;
    TextView recoveruser,recoverpassword;
    GoogleSignInClient mGoogleSignInClient;
    int RC_SIGN_IN=0;
    //variables fb
    CallbackManager callbackManager;
    LoginButton loginButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_loggin);
        register=findViewById(R.id.buttonregister);
        recoveruser=findViewById(R.id.recoveruser);
        recoverpassword=findViewById(R.id.recoverpassword);
        signInButton = findViewById(R.id.sign_in_button);
        callbackManager= CallbackManager.Factory.create();
        loginButton =  findViewById(R.id.login_button);
         signInButton.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 switch (v.getId()) {
                     case R.id.sign_in_button:
                         signIn();
                         break;
                     // ...
                 }
             }
         });
        //configuración para google:
        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
        mGoogleSignInClient = GoogleSignIn.getClient(this,gso);


    }

    private void signIn() {
        Intent signInIntent = mGoogleSignInClient.getSignInIntent();
        startActivityForResult(signInIntent,RC_SIGN_IN);
    }
    @Override
    public void onActivityResult(int requestCode,int resultCode,Intent data) {
        super.onActivityResult(requestCode,resultCode,data);

        if (requestCode == RC_SIGN_IN) {

            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
            handleSignInResult(task);
        }
    }
    private void handleSignInResult(Task<GoogleSignInAccount> completedTask) {
        try {
            GoogleSignInAccount account = completedTask.getResult(ApiException.class);

             Intent intent=new Intent(loggin.this,MainActivity.class);
             startActivity(intent);
            // Signed in successfully,show authenticated UI.

        } catch (ApiException e) {

            Log.w("error","signInResult:failed code=" + e.getStatusCode());

        }
    }
 }
    

片段：

public class perfil_user extends Fragment {
        public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
            View view=inflater.inflate(R.layout.perfil_user,container,false);
            GoogleSignInClient mGoogleSignInClient;
            GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
            mGoogleSignInClient = GoogleSignIn.getClient(getContext(),gso);
            ImageView imageView=view.findViewById(R.id.image_user);
            TextView nameuser=view.findViewById(R.id.NameUser);
            TextView email=view.findViewById(R.id.setmail);
            GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getContext());
            if (acct != null) {
                String personName = acct.getDisplayName();
                String personEmail = acct.getEmail();
                Uri personPhoto = acct.getPhotoUrl();
                nameuser.setText(personName);
                email.setText(personEmail);


            }

            return  view;

        }

    }
