What code i need to input, and where, to switch to a different fragment once item is clicked?

on my activity_main_drawer i got many items but i don't know what code and where it goes to add for switching fragment
<?xml version="1.0" encoding="utf-8"?>

</menu>
this is the java HomePage where i am struggling to understand where and what code to add
public class HomePage extends AppCompatActivity {
private AppBarConfiguration mAppBarConfiguration;
#SuppressLint("WrongViewCast")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_page);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_gallery, R.id.nav_slideshow)
.setDrawerLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.home_page, menu);
return true;
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
}
and this is one of the fragment java as example.
public class GalleryFragment extends Fragment {
private GalleryViewModel galleryViewModel;
public View onCreateView(#NonNull LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
galleryViewModel =
ViewModelProviders.of(this).get(GalleryViewModel.class);
View root = inflater.inflate(R.layout.fragment_gallery, container, false);
final TextView textView = root.findViewById(R.id.text_gallery);
galleryViewModel.getText().observe(getViewLifecycleOwner(), new Observer<String>() {
#Override
public void onChanged(#Nullable String s) {
textView.setText(s);
}
});
return root;
}
}
it would be great as example to switch from HomePage to GalleryFragment and back

try-->
put this in your mainactivity:-
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_contests) {
//intent to next activity
} else if (id == R.id.nav_rules) {
//just an example
String message = "Text I want to share.";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));
} else if (id == R.id.nav_profile) {
///your actions
}
} else if (id == R.id.nav_calendar) {
}
} else if (id == R.id.nav_gallery) {
}
} else if (id == R.id.nav_stats) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

Add in you activity. It works
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.nav_home) {
}else if (id == R.id.nav_logout) {
logOut(HomePage.this, "Logout due to nav. logout");
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

NavigationDrawer doesn't work, it's closing before doing something

I made an empty activity and then I changed it to a DrawerLayout and every time I open the Menu and click an item the drawer is closing and nothing happens like i'm just opening and closing it, can't doing anything else.
This is the layout
<?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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:id="#+id/navigation_home_drawer">
<com.google.android.material.navigation.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/mainmenu"
>
</com.google.android.material.navigation.NavigationView>
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<com.google.android.gms.maps.MapView
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.drawerlayout.widget.DrawerLayout>
And this is the Java Code
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback, NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private MapView mMapView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = findViewById(R.id.navigation_home_drawer);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
NavigationView navigationView =findViewById(R.id.navigation);
navigationView.setNavigationItemSelectedListener(this);
mMapView = findViewById(R.id.map);
initGoogleMap(savedInstanceState);
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
if(mToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
int id = menuItem.getItemId();
switch (id) {
case R.id.nav_home:{
Intent i = new Intent(this, MainActivity.class);
startActivity(i);
finish();
break;
}
case R.id.nav_profile: {
Intent i = new Intent(this, ProfileActivity.class);
startActivity(i);
finish();
break;
}
case R.id.nav_settings: {
Intent i = new Intent(this, SettingsActivity.class);
startActivity(i);
finish();
break;
}
}
return true;
}
}
Here's the menu layout
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/nav_home"
android:title="Home"
android:icon="#drawable/ic_home_black_24dp">
</item>
<item
android:id="#+id/nav_profile"
android:title="My Profile"
android:icon="#drawable/ic_person_black_24dp">
</item>
<item
android:id="#+id/nav_settings"
android:title="Settings"
android:icon="#drawable/ic_settigs">
</item>
</menu>
I also have the code for Map in this file, but it's not important, when I select an item from that menu I just want to change the activity to that, but nothing happens, only close the navigation, can you please tell me if I forgot to add something or what should I change to make the navigation work? Thank you in advance!

You can use this code to make navigation drawer :
NavigationView navigationView;
DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
navigationView = findviewbyid(R.id.nav_drawer_home);
drawerLayout = findviewbyid(R.id.drawer_home);
drawerLayout.requestLayout();
setUpNavigationView();
}
private void setUpNavigationView() {
navigationView.setNavigationItemSelectedListener(menuItem -> {
switch (menuItem.getItemId()) {
case R.id.nav_recharge:
break;
case R.id.nav_offers:
break;
case R.id.nav_rides:
break;
case R.id.nav_refer_friend:
break;
case R.id.nav_wallet:
break;
case R.id.nav_about_us:
break;
case R.id.nav_feedback:
break;
default:
break;
}
if (menuItem.isChecked())
menuItem.setChecked(false);
else
menuItem.setChecked(true);
menuItem.setChecked(true);
drawerLayout.closeDrawers();
return true;
});
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar,
R.string.openDrawer, R.string.closeDrawer) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
}
#Override
public void onBackPressed() {
if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
drawerLayout.closeDrawers();
return;
}
super.onBackPressed();
}

How to fix Android studio 3.5 navigation activity template onNavigationItemSelected not working
(5 answers)
Closed 3 years ago.
I am trying to set up a Navigation Activity in my application. The problem is that I cannot switch between the Menu fragments. It looks like the menu items are not clickable.
I tried to set up the Navigation Activity in the same way I have already set up a menu (Action Bar) before but it's just not working. Also with on Click Listener, the items don't react.
My question is now on how to make the onNavigationItemSelected() method work?
Sorry for the mass of code.

fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(

R.id.nav_tools, R.id.nav_share, R.id.nav_send)

.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
Toolbar myToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(myToolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.nav, menu);
return true;
}
#Override
public boolean onSupportNavigateUp() {

return true;
}
case R.id.nav_gallery:
// User chose the "Favorite" action, mark the current item
// as a favorite...
return true;
}
return super.onOptionsItemSelected(item);

How to solve navigation bar with navigation bottom problem

My question is that I was trying to make a simple app, and I used both navigation bar and bottom navigation in the same activity, but I am having a simple problem, such as When I run the app, I'm in home fragment, but when I drag the navigation bar and click on movies, it goes into movies fragment, and my movies item got checked, but the problem is when I again click on home in bottom navigation menu than in my navigation menu the movies item still become checked. Please tell how should I do that if I click on home in bottom navigation then in my navigation bar my movies item become unchecked.
Hope you will understand my problem
Here is my code:-
MainActivity : -
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
private FirebaseAuth mAuth;
private DrawerLayout drawerLayout;
private BottomNavigationView.OnNavigationItemSelectedListener navListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override

break;

break;
case R.id.nav_features:
selectedFragment = new FeaturesFragment();
break;
case R.id.nav_myMusic:

return true;
}

Please answer me if you found the solution

Make one file in drawable like "bottom_icon_color.xml"
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="#color/red" />
<item android:state_checked="false" android:color="#color/lightgray" />
</selector>
Then apply it to your bottom navigation
app:itemIconTint="#drawable/bottom_icon_color"
app:itemTextColor="#drawable/bottom_icon_color"

According to the problem you had mentioned in the question
you have to first store the previously clicked MenuItem and then make it as unchecked by using setCheckable(false) of MenuItem.
I'm assuming that the rest of all the functions are working, for example, check the item of NavigationView when the bottom navigation item is selected.
In your onNavigationItemSelected store, the clicked MenuItem in one variable say prevMenuItem of type MenuItem.
Now in your BottomNavigationView.OnNavigationItemSelectedListener() make this prevMenuItem as unchecked using this.
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.getMenu().findItem(previousMenuItem.getId()).setCheckable(false);

How to change xml parameters programmatically in Android

I have been working on an app that requires changing the nav menu options based on the User Type. To display the nav menu, i am using NavigationView. The only part i am stuck on is changing the app:menu parameter to another menu design (activity_nav_drawer2.xml).

You can set visibility of different menu items according to the user type.
Instead of clearing the navigation_menu items, set visibilities for different items accordingly.
