How to open New Activity by clicking Navigation Drawer Item in Android

How can I open New Activity by clicking a Navigation Drawer Menu Item?
Share_Home.java
public class Share_Home extends AppCompatActivity {
private long backPressedTime;
private ActionBarDrawerToggle toggle;
private DrawerLayout drawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_share_home);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
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.
SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(this, getSupportFragmentManager());
ViewPager viewPager = findViewById(R.id.view_pager);
viewPager.setAdapter(sectionsPagerAdapter);
TabLayout tabs = findViewById(R.id.tabs);
tabs.setupWithViewPager(viewPager);
tabs.setTabMode(TabLayout.MODE_SCROLLABLE);
tabs.getTabAt(1).select();
toggle = new ActionBarDrawerToggle(this, drawer, R.string.open, R.string.close);
drawer.addDrawerListener(toggle);
toggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
if (toggle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
}

Set a NavigationItemSelectedListener to you NavigationView:
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
int id=menuItem.getItemId();
if (id == R.id.xxx){
Intent newIntent = new Intent(this, NewActivity.class);
startActivity(newIntent);
}
return true;
}
});
Also change your layout.
Instead of:
<androidx.drawerlayout.widget.DrawerLayout >
<include layout="#layout/app_bar_main" />
<com.google.android.material.navigation.NavigationView/>
<include layout="#layout/activity_tabs_menu"/>
</androidx.drawerlayout.widget.DrawerLayout>
Use:
<androidx.drawerlayout.widget.DrawerLayout >
<include layout="#layout/app_bar_main" />
<com.google.android.material.navigation.NavigationView/>
</androidx.drawerlayout.widget.DrawerLayout>
moving the <include layout="#layout/activity_tabs_menu"/> inside the app_bar_main layout.

You have to override onNavigationItemSelected and check the id of the selected menu item and then open Activity:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.activity1:
startActivity(new Intent(this, Activity1.class));
break;
case R.id.activity2:
startActivity(new Intent(this, Activity2.class));
break;
}
drawer.closeDrawer(GravityCompat.START);
return true;
}
And remember to add id to every item in menu layout:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/activity1"
android:title="#string/activity1" />
<item
android:id="#+id/activity2"
android:title="#string/activity2" />
</menu>

Here is how you can do it:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
final int itemId = item.getItemId();
if (itemId == R.id.nav_Setting) {
Intent newIntent = new Intent(getApplicationContext(), YourSettingActivity.class);
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(newIntent);
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.nav_menu_item, menu);
return super.onCreateOptionsMenu(menu);
}

You get a listener in your NavigationView that listens to the item pressed. So you can set the listener and then start an activity when a particular item is pressed in the NavigationDrawer, like so:
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.menu_item_1:
Intent intent = new Intent(this, ItemActivity.class);
startActivity(intent);
break;
}
}
});

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

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;

int id = item.getItemId();

I don't get it if MainActivity.class is created to handle all of it, then its created UI views and fragments, where should I be updating? And why are they null?

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"

android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"

</com.google.android.material.navigation.NavigationView>
<androidx.constraintlayout.widget.ConstraintLayout

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 super.onOptionsItemSelected(item);
}

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();
}

Navigation Drawer is not clickable [duplicate]

I am trying to use NavigationView from Android Support Design library in my app. For some reason, OnNavigationItemSelected listener is not being called. Here is my code
Activity Layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/drawer_menu" />
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>
Activity onCreate()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutID());
toolbar = (Toolbar) findViewById(R.id.activity_toolbar);
setSupportActionBar(toolbar);
toolbar.inflateMenu(R.menu.common_menu);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayHomeAsUpEnabled(true);
}
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(final MenuItem menuItem) {
Snackbar.make(contentLayout, menuItem.getTitle() + " pressed", Snackbar.LENGTH_LONG).show();
menuItem.setChecked(true);
// allow some time after closing the drawer before performing real navigation
// so the user can see what is happening
drawerLayout.closeDrawer(GravityCompat.START);
mDrawerActionHandler.postDelayed(new Runnable() {
#Override
public void run() {
navigate(menuItem.getItemId());
}
}, DRAWER_CLOSE_DELAY_MS);
drawerLayout.closeDrawers();
return true;
}
});
usernameTextView = (TextView) findViewById(R.id.drawer_header_username);
usernameTextView.setText(getAppDContext().getAccount().getUsername());
}

When you make XML layout, you should write down NavigationView after BaseLayout (FrameLayout, LinearLayout, etc..)
<DrawerLayout>
<FrameLayout />
<NavigationView />
</DrawerLayout>

For me this did the trick!
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.bringToFront();

Your activity main layout should look like this:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/navigationDrawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/activity_main_content" />
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
style="#style/NavigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right"
app:headerLayout="#layout/header"
app:menu="#menu/menu_drawer"/>
</android.support.v4.widget.DrawerLayout>
In this NavigationView I linked header.xml and menu_drawer.xml (from menu folder)
for example menu_drawer.xml :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav1"
android:checked="true"
android:icon="#drawable/logo"
android:title="Navigation item 1"/>
<item
android:id="#+id/nav2"
android:icon="#drawable/logo"
android:title="Navigation item 2"/>
</group>
</menu>
than your java code:
public class ActivityMain extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpToolbar();
setUpNavDrawer();
}
private void setUpNavDrawer() {
NavigationView view = (NavigationView) findViewById(R.id.navigationView);
mDrawerLayout = (DrawerLayout) findViewById(R.id.navigationDrawer);
view.setNavigationItemSelectedListener(this);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawerOpen, R.string.drawerClose);
mDrawerLayout.addDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
}
Check if this work for you. In my project works like a charm.
