¿how to fix side menu functionality in android studio?

I am working with Android Studio and I have a side menu, most of the options are working because I configure them in "mobile_navigation".
But I need one of my items to open a URL and I don't know how to do it.
My menu xml is:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
tools:showIn="navigation_view">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_profile"
android:icon="#drawable/profile"
android:title="#string/menu_profile" />
<item
android:id="#+id/nav_web"
android:icon="#drawable/web"
android:title="#string/menu_web" />
</group>
I handle the actions of the items like this:
<fragment
android:id="#+id/nav_profile"
android:name="com.myApp.myApp.ui.profile.ProfileFragment"
android:label="#string/menu_profile"
tools:layout="#layout/fragment_profile">
<action
android:id="#+id/action_nav_profile_to_nav_fragment2"
app:destination="#id/nav_correccion" />
</fragment>
<fragment
android:id="#+id/nav_web">
</fragment>
Tried using onOptionsItemSelected (), but it still doesn't work for me. Please help
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
private AppBarConfiguration mAppBarConfiguration;
private SharedPreferences preferences;
private DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
//navigationView.setNavigationItemSelectedListener(this);
// 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_perfil, R.id.nav_web
)
.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.activity_main_drawer, menu);
return true;
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id= item.getItemId();
FragmentManager fragmentManager= getSupportFragmentManager();
if(id==R.id.nav_web){
Uri uri=Uri.parse("https://google.com.co");
Intent intent=new Intent(Intent.ACTION_VIEW,uri);
startActivity(intent);
}
DrawerLayout drawerLayout =(DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}

As per the Tie destinations to menu items section, Navigation uses the IDs you add to your menu xml, matching them to destinations in your navigation graph xml file.
So if you had a menu item such as
<item
android:id="#+id/nav_web"
android:icon="#drawable/web"
android:title="#string/menu_web" />
and wanted it to start a different activity, you could add an <activity> destination to your navigation graph:
<activity
android:id="#+id/nav_web"
app:data="https://google.com.co"
app:action="android.intent.action.VIEW" />
And because they have the same ID, your activity would be started when you click that item in your menu.

onNavigationItemSelected is not working on Navigation Drawer

I'm trying to get click event of Navigation Drawer item.
What I did is as below.
(1) Create a new Android source project selecting 'Navigation Drawer Activity' on 'Select a Project Template'. (Min SDK : API 22 - Lollipop)
(2) Add one item on '/res/menu/activity_main_drawer.xml'.
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_home"
android:icon="#drawable/ic_menu_camera"
android:title="#string/menu_home" />
<item
android:id="#+id/nav_gallery"
android:icon="#drawable/ic_menu_gallery"
android:title="#string/menu_gallery" />
<item
android:id="#+id/nav_slideshow"
android:icon="#drawable/ic_menu_slideshow"
android:title="#string/menu_slideshow" />
</group>
<item
android:id="#+id/menu_notification"
android:icon="#drawable/ic_menu_slideshow"
android:title="Notification" />
(3) MainActivity implements NavigationItemSelectedListener, and define event function - onNavigationItemSelected()
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_notification) {
Toast.makeText(this, "Menu - Notification", Toast.LENGTH_SHORT).show();
}
return true;
}
(4) Set NavigationItemSelectedListener to MainActivity in onCreate() method.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
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);
navigationView.bringToFront();
navigationView.setNavigationItemSelectedListener(this);
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);
}
This is all I did. After run this application on Emulator, I clicked new menu item (Notification), but nothing happened.
onNavigationItemSelected() can not get event of item click.
What I have to do to get click event of Navigation Drawer item?

The reason why this doesn't work is because you are using Navigation Component. If you want onNavigationItemSelected method to be called, remove the mentioned line below:
NavigationUI.setupWithNavController(navigationView, navController);
After that, keep in mind that you should manage selected items manually as Navigation won't do it for you anymore.

Navigation Drawer item click

I have DrawerLayout and NavigationView. There are two fragments which are changed when I click on item in navigation drawer and that works well:
<fragment
android:id="#+id/nav_settings"
android:label="#string/menu_settings"
tools:layout="#layout/fragment_settings" />
<fragment
android:id="#+id/nav_themes"
android:label="#string/menu_themes"
tools:layout="#layout/fragment_themes" />
The problem is that I have several other items in the drawer menu that are not Fragments and I can not make them clickable:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view">
<group
android:id="#+id/group_1"
android:checkableBehavior="single">
<item
android:id="#+id/nav_settings"
android:icon="#drawable/ic_keyboard_settings"
android:title="#string/menu_settings" />
<item
android:id="#+id/nav_themes"
android:icon="#drawable/ic_theme"
android:title="#string/menu_themes" />
</group>
<group android:id="#+id/group_2">
<item
android:id="#+id/nav_developer_page"
android:icon="#drawable/ic_developer_page"
android:title="#string/menu_developer_page" />
<item
android:id="#+id/nav_privacy_policy"
android:icon="#drawable/ic_privacy_policy"
android:title="#string/menu_privacy_policy" />
</group>
</menu>
Here is the code:
setSupportActionBar(toolbar)
toggle = object : ActionBarDrawerToggle(this, drawer_layout, toolbar, 0, 0) {
override fun onDrawerClosed(drawerView: View) {
super.onDrawerClosed(drawerView)
syncState()
}
override fun onDrawerOpened(drawerView: View) {
super.onDrawerOpened(drawerView)
syncState()
}
}
toggle.syncState()
drawer_layout.addDrawerListener(toggle)
val navController = findNavController(R.id.nav_host_fragment)
appBarConfiguration = AppBarConfiguration(setOf(
R.id.nav_settings, R.id.nav_themes, R.id.nav_developer_page), drawer_layout)
nav_view.setupWithNavController(navController)
toggle.syncState()
When I set NavigationItemSelectedListener it breaks navigation for Fragments.
How can I make those two items clickable and call a function?

The solution is to get the menu item from the navigation view and set a click listener:
val signoutMenuItem = binding.nvNavigationDrawerNavigationView.menu.findItem(id.navigation_drawer_menu_sign_out)
signoutMenuItem.setOnMenuItemClickListener {
navigationDrawerMainActivityViewModel.signOut()
true
}
and do not include non-fragment items in AppBarConfiguration:
appBarConfiguration = AppBarConfiguration(
setOf(
id.drawerFragmentX,
id.drawerFragmentY,
//id.navigation_drawer_menu_sign_out <- Do NOT include
), drawerLayout
)
setupActionBarWithNavController(navController, appBarConfiguration)
navView.setupWithNavController(navController)
This solution is identical to https://stackoverflow.com/a/59451345/5189200.

Add menu Item in a group dynamically android navigation menu

I have a navigation menu which looks like this -
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/nav_home"
android:icon="#drawable/ic_home"
android:title="Home" />
<item
android:id="#+id/nav_logout"
android:icon="#drawable/ic_logout"
android:title="Logout" />
<item
android:id="#+id/choose_bus"
android:title="Choose a bus">
<menu>
<group
android:id="#+id/group_select_bus"
android:checkableBehavior="single">
<!--<item-->
<!--android:id="#+id/menu_option1"-->
<!--android:title="Bus 1" />-->
<!--<item-->
<!--android:id="#+id/menu_option2"-->
<!--android:title="Bus 2" />-->
</group>
</menu>
</item>
I want to add menu_option1 and menu_option2 dynamically from the activity. I tried this but nothing adding -
#Override
public boolean onNavigationItemSelected(MenuItem item) {
NavigationView navView = (NavigationView) findViewById(R.id.nav_view);
Menu menu = navView.getMenu();
MenuItem item1 = menu.getItem(2);
SubMenu subMenu = item1.getSubMenu();
subMenu.add("Bus 1");
subMenu.add("Bus 2");
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}

Try some thing like this
Menu menu = navView.getMenu();
menu.add(R.id.group_select_bus,Menu.NONE,Menu.NONE,Youritem);

Try this:
MenuItem item = mNavigationView.getMenu().getItem(2);
item.getSubMenu().add(R.id.group_select_bus, id, Menu.NONE, "Youritem");

Another approach is to add all items in navigation menu and then change their visibility on specific activity or fragment, like
MenuItem item = mNavigationView.getMenu().getItem(5);
item.setVisible(false);

Seems a little late to answer. There is workaround/hack for this. No need to add list. Just add this little line above your code. It surely works.
override fun onNavigationItemSelected(item: MenuItem): Boolean {
when (item.itemId) {
R.id.candidates -> {
binding.navSideView.post {
navSideView.menu.findItem(R.id.candidateManagement).isVisible = !navSideView.menu.findItem(R.id.candidateManagement).isVisible
}
}
}
return true
}
You need to add navigationview.post Runnable before changing visibility. It will update the menu. It works with group too. :)

onNavigationItemSelected not working in NavigationView

Please can someone help me with fragments from the navigation drawer, for some reason I can't get them to work and all the code looks right.
Here is the link to the source code.

Use this code:
navigationView = (NavigationView) findViewById(R.id.navigationView);
navigationView.bringToFront();

Have a look at your MainActivity.java.
You have implemented the callbacks for NavigationView.OnNavigationItemSelectedListener in MainActivity as below,
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// blah blah
}
Also check the setupDrawerContent method.
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
drawerLayout.closeDrawers();
return true;
}
});
}
In this method you are creating a local OnNavigationItemSelectedListener.
So you are not using the OnNavigationItemSelectedListener that you have overridden in MainActivity.
The solution is to use this as argument for setNavigationItemSelectedListener. By doing this all your clicks will go the onNavigationItemSelected of MainActivity rather than going to the local onNavigationItemSelected.
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(this);
}
Also move the code in the local onNavigationItemSelected to the onNavigationItemSelected of MainActivity.
So your onNavigationItemSelected will be something like this,
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// Handle navigation view item clicks here.
int id = menuItem.getItemId();
menuItem.setChecked(true);
drawerLayout.closeDrawers();
if (id == R.id.nav_home) {
// Handle the home action
Toast.makeText(this, "Home", Toast.LENGTH_SHORT).show();
} else if (id == R.id.nav_the_wetlands) {
Toast.makeText(this, "The Wetlands", Toast.LENGTH_SHORT).show();
TheWetlandsFragment theWetlandsFragment = new TheWetlandsFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.relativelayout_for_fragment, theWetlandsFragment, theWetlandsFragment.getTag()).commit();
} else if (id == R.id.nav_the_mistbelt_forests) {
Toast.makeText(this, "The Mistbelt Forests", Toast.LENGTH_SHORT).show();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Also change your activity_main_drawer_view.xml as follows to solve the multiple selection issue you have in the Navigation Drawer,
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_home"
android:icon="#drawable/ic_dashboard"
android:title="Home" />
</group>
<item android:title="Information">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_the_wetlands"
android:icon="#drawable/ic_event"
android:title="The Wetlands" />
<item
android:id="#+id/nav_the_mistbelt_forests"
android:icon="#drawable/ic_event"
android:title="The Mistbelt Forests" />
<item
android:id="#+id/nav_the_grasslands"
android:icon="#drawable/ic_event"
android:title="The Grasslands" />
</group>
</item>
<item android:title="Quick Go To">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_accommodation"
android:icon="#drawable/ic_event"
android:title="Accommodation" />
<item
android:id="#+id/nav_cuisine"
android:icon="#drawable/ic_forum"
android:title="Cuisine" />
<item
android:id="#+id/nav_leisure_activites"
android:icon="#drawable/ic_forum"
android:title="Leisure & Activites" />
<item
android:id="#+id/nav_agri_tourism"
android:icon="#drawable/ic_forum"
android:title="Agri-tourism" />
<item
android:id="#+id/nav_education"
android:icon="#drawable/ic_forum"
android:title="Education" />
<item
android:id="#+id/nav_arts_crafts_decor"
android:icon="#drawable/ic_forum"
android:title="Arts, Crafts & DeCor" />
<item
android:id="#+id/nav_selective_shopping"
android:icon="#drawable/ic_forum"
android:title="Selective Shopping" />
<item
android:id="#+id/nav_for_children"
android:icon="#drawable/ic_forum"
android:title="For Children" />
</group>
</item>
<item android:title="Midlands Animals">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_midlands_birding_checklist"
android:icon="#drawable/ic_dashboard"
android:title="Midlands Birding Checklist" />
<item
android:id="#+id/nav_midlands_mammals_checklist"
android:icon="#drawable/ic_dashboard"
android:title="Midlands Mammals Checklist" />
</group>
</item>
</menu>
Good luck.

Don't use
NavigationUI.setupWithNavController(navigationView, navController);
instead of it do this
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Toast.makeText(MainActivity.this, "clicked", Toast.LENGTH_SHORT).show();
return false;
}
});

I have also faced the same problem some time back, and at the end i realized that i have not wrote the 2nd line of the following code
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(this);
you make sure you have written the same otherwise your listener will not work

in my case i forgot to initialize navigation menu.
kindly follow following code:
public void initSideMenu() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
happy coding...

Make sure you have implement the interface NavigationView.OnNavigationItemSelectedListener.
Second point make sure to add these lines otherwise listnere will not be called.
navigationView=(NavigationView) findviewbyid(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(this);

Add this line
navigationView.bringToFront();
Its works for me
