Change Navigationview Items When User Is Logged

Change NavigationView items when user is logged

I thing the best approach to this is to include all your items in the menu and the change their visibility.

<item
    android:id="@+id/login"
    android:icon="@drawable/ic_action_person"
    android:title="@string/login"
    android:visible="true" />

<item
    android:id="@+id/logout"
    android:icon="@drawable/ic_action_person"
    android:title="@string/logout"
    android:visible="false" />

then

navigationView.getMenu().findItem(R.id.login).setVisible(false);
navigationView.getMenu().findItem(R.id.logout).setVisible(true);

You can also do this with whole groups of items

<group
    android:id="@+id/group_1"
    android:checkableBehavior="single"
    android:visible="false">
    ...
</group>

and

navigationView.getMenu().setGroupVisible(R.id.group_1, true)

How can I remove a MenuItem if user is logged in or change the title?

You will have to keep references to the menu items you want to mutate(change name, make invisible etc). To achieve this use follwoing code in your activity

 // Declate two variables in your activity
 private lateinit var register: MenuItem
 private lateinit var logIn: MenuItem

// Now initialize them in your activity's onCreate as follows
var navigationView = findViewById(R.id.idOfNavigationView)
register = navigationView.menu.findItem(R.id.idOfRegister)
logIn = navigationView.menu.findItem(R.id.idOfLogin)

Now you have your menu items and you can change their title or make them invisible.
For example if you want to hide the register menu item and change the title of login, you will do the following

// Once user has logged in successfully, use following lines to change menu items as you wish
register.isVisible = true
logIn.title = "logout"

Navigation Components: Switch Menu of Navigation Drawer (for logged in users)

You can access Activity from Fragment through interface:

1. Create and interface say LoginSuccessListener
2. Implements this in your Activity
3. Inside fragment receive this listener inside onAttach
4. Use it as you needed to update Navigation Menu

change user's name in navigation menu when user logs in

You can use the code below to get the navigation view and replace "Your Text Here" with your username

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
View headerView = navigationView.getHeaderView(0);
TextView navUsername = (TextView) headerView.findViewById(R.id.navUsername);
navUsername.setText("Your Text Here");

This worked for me...

Menu item visibility doesnt change partly

In order to make sure that mAuth.currentUser is null, you need to add a listener when the user has logged out so that you can update visibility of menu items; because you might call updateUI() before the user sign out, so mAuth.currentUser still has a value.

So in onNavigationItemSelected() callback: add this listener

R.id.nav_logout_item->{

    mAuth.signOut()
        
    AuthUI.getInstance()
            .signOut(this) // context
            .addOnCompleteListener {
            
                // User has been logged out 
                updateUI()
                
            }
}

And do the same for the login behavior to return the visibility back to the menu items.

How to dynamically change navigation bar item's logo in Java class?

Try this,

NavigationView navigationView = (NavigationView)findViewById(R.id.nav_view);
navigationView.getMenu().getItem(1).setIcon(R.drawable.com_facebook_button_icon_white);

Hope this helps

Reload navigationView content by pressing an id in the navigationView

Ok, so my way to do seems to be a terrible idea. After some research, it seems that we can use visible true or visible false for an item or a group in a menu.

So it's just necessary to do an onClick method and set the group visible or invisible when clicking on a pic or another.

How to change the text view when a new user is logged in?

Create one Global PrefManager class like this and create a three field to set data

public class PrefManager {
    // Shared preferences file name
    public static final String PREF_NAME = "PACKAGE_NAME" + "_Preferences";

private static final String KEY_EMPID = "Emp_ID";
    private static final String KEY_EMPCODE = "Emp_Code";
    private static final String KEY_EMP_NAME = "Emp_Name";

  SharedPreferences pref;
    // Editor for Shared preferences
    Editor editor;
    // Context
    Context _context;
    // Shared pref mode
    int PRIVATE_MODE = 0;

    public PrefManager(Context context) {
        this._context = context;
        pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
        editor = pref.edit();
    }

public String getEmpID() {
        return pref.getString(KEY_EMPID, null);
    }

    public void setEmpID(String token) {
        editor.putString(KEY_EMPID, token);
        editor.commit();
    }

    public String getEmpCode() {
        return pref.getString(KEY_EMPCODE, null);
    }

    public void setEmpCode(String token) {
        editor.putString(KEY_EMPCODE, token);
        editor.commit();
    }

    public String getEmpName() {
        return pref.getString(KEY_EMP_NAME, null);
    }

    public void setEmpName(String token) {
        editor.putString(KEY_EMP_NAME, token);
        editor.commit();
    }
}

Login Activity Call Intent Time Set Data to shared Preferences you also save data on the register time

public class LoginActivity{

PrefManager pref;

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_login);
// inilize pref manager class
 pref = new PrefManager(this);

}

 if (currentUser != null) {
                //Snackbar.make(buttonLogin, "Login Successful!", Snackbar.LENGTH_LONG).show();
                //User Logged in successfully Launch You home screen activity

                Intent intent = new Intent (Login.this,Navigation.class);

pref.setEmpID(//passyour employee id);
                startActivity(intent);
                finish();
            } 

on navigation, activity get data from shared preferences and store to string and set to drawer textview

  public class navigationActivity()

***PrefManager pref;***
String EmpId;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_navigation);

    ***pref = new PrefManager(this);***
    EmpId = pref.getEmpID;
    }

    // OnnavigationDrawer header

     textView.setText("EmpID:"+EmpId);
