如何将Google登录信息从Firebase数据库发送到导航抽屉？

问题描述 投票：0回答：1

我有一个登录活动，在这个活动中，用户可以通过firebase登录他们的Google账户，它工作得很完美，但我遇到的问题是将这些信息发送到导航抽屉。我在StackOverflow上几乎尝试了所有关于这个问题的代码，但似乎没有任何东西能与我的代码一起工作，有人能帮助我吗，我非常感激。

这是我目前所尝试的。

MainActivity

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {

private DrawerLayout drawer;
TextView text;
ImageView image;
FirebaseAuth mAuth;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    text = findViewById(R.id.nav_text);
    image = findViewById(R.id.nav_image);

    mAuth = FirebaseAuth.getInstance();

    if (mAuth.getCurrentUser() != null) {
        FirebaseUser user = mAuth.getCurrentUser();
        updateUI(user);
    }



    drawer = findViewById(R.id.drawer_layout);
    NavigationView navigationView = findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    View header = navigationView.getHeaderView(0);
    TextView text = (TextView) header.findViewById(R.id.nav_text);


    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar,
            R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();



}




private void updateUI(FirebaseUser user) {
    if (user != null) {
        String name = user.getDisplayName();
        String email = user.getEmail();
        String photo = String.valueOf(user.getPhotoUrl());

        text.append(name + "\n");
        text.append(email);
        Picasso.get().load(photo).into(image);
    } else {
        Picasso.get().load(R.drawable.ic_firebase_logo).into(image);
    }
}

导航头.xml

有同样的问题。做了这个。

NavigationView navigationView = findViewById(R.id.nav_view);
View headerLayout = navigationView.getHeaderView(0);
    .
    .
    .
text = headerLayout.findViewById(R.id.nav_text);
image = headerLayout.findViewById(R.id.nav_image);

我不知道你是否尝试过这个，但它为我工作。
