How do you use a toolbar across all activies

I have made a toolbar and Navigation Drawer java class along with its XML, it works perfectly.
Here is the code:
Java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar1);
setSupportActionBar(toolbar);
//This part is new for NavigationDrawer:
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);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.items, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.ticket:
startActivity(new Intent(NavigationActivity.this, TicketMasterActivity.class));
break;
case R.id.recipe:
Intent goToRecipe = new Intent(NavigationActivity.this, RecipeSearchActivity.class);
startActivity(goToRecipe);
break;
case R.id.covid:
Intent goToCovid = new Intent(NavigationActivity.this, MainActivity_covid.class);
startActivity(goToCovid);
break;
case R.id.album:
Intent goToAlbum = new Intent(NavigationActivity.this, MainActivity.class);
startActivity(goToAlbum);
break;
case R.id.help:
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setTitle(R.string.WelcomeTotal);
alertDialogBuilder.setMessage(R.string.WelcomeTotalMessage);
alertDialogBuilder.setPositiveButton("OK", (click2, arg) -> {
});
alertDialogBuilder.create().show();
}
return true;
}
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.ticket1) {
startActivity(new Intent(NavigationActivity.this, TicketMasterActivity.class));
} else if (id == R.id.recipe1) {
Intent goToRecipe = new Intent(NavigationActivity.this, RecipeSearchActivity.class);
startActivity(goToRecipe);
} else if (id == R.id.covid1) {
Intent goToCovid = new Intent(NavigationActivity.this, MainActivity_covid.class);
startActivity(goToCovid);
} else if (id == R.id.album1) {
Intent goToAlbum = new Intent(NavigationActivity.this, MainActivity.class);
startActivity(goToAlbum);
} else if (id == R.id.share) {
Toast.makeText(this, "this feature is not yet implemented", Toast.LENGTH_LONG).show();
} else if (id == R.id.send) {
Toast.makeText(this, "this feature is not yet implemented", Toast.LENGTH_LONG).show();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
XML:
<LinearLayout xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

I want to make it so that every activity uses this specific toolbar. And that every toolbar is preloaded with the items that I put inside in the java class. Is this possible and if so, how?
Thank you.

Create and Activity which will behave as a Parent Activity with your own custom toolbar.
Extend that activity where ever you want.

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;

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 =

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);

In my Fragment is the Layout of Mainactivity also shown

I'm working the first time with Fragments, so sorry if I did smt very stupid :D
I have a Navigation Drawer Activity. When I click in it on the first item i want to open a Fragment. When I open it, there is not only the Layout of the Fragment shown, but also the layout of my MainActivity, it looks very strange.
[1]: https://i.stack.imgur.com/iqTAq.png MainActivity
[2]: https://i.stack.imgur.com/kULQY.png Navigation Drawer
[3]: https://i.stack.imgur.com/T2vDJ.png First Fragment
How can I solve the problem?
Here is my code if you need it:
MainActivity(Navigation Drawer Templated, I wrote only in the onNavigationItemSelected, so that it goes to the fragment when I click on the first item:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) 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 = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {
setTitle("First Fragment");
first first = new first();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment, first).commit();
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
content_main (It should belong to MainActivity)
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout 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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.gsr.fragmenttest.MainActivity"
tools:showIn="#layout/app_bar_main">
<FrameLayout
android:id="#+id/fragment"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="This is the Mainactivity, no fragemnt"/>
</FrameLayout>
</RelativeLayout>
First Fragment Activity
public class first extends Fragment {
Button btn;
TextView textView;
public first() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_first, container, false);
btn=(Button)v.findViewById(R.id.button);
textView=(TextView)v.findViewById(R.id.textView);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
textView.setText("Nice, it works !!");
}
});
// Inflate the layout for this fragment
return v;
}
}
And at least the fragment layout file
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.gsr.fragmenttest.first">
<!-- TODO: Update blank fragment layout -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="Hello Fragment"
android:textSize="50dp"/>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"/>
</RelativeLayout>
</FrameLayout>
I hope someone can help me :)

Add a background to your fragment layout, it should solve your problem.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white" //Your background color
tools:context="com.gsr.fragmenttest.first">
<!-- TODO: Update blank fragment layout -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
...

I think the problem is in your activity layout
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
try to change your main activity layout like above. Hope it will solve your problem.

1) implements first.OnOnFragmentInteractionListener
2) in onNavigationItemSelected method put this code
if (id == R.id.nav_camera) {
setTitle("First Fragment");
first first = new first();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment, new first()).commit();
3)In first fragment use this line
import android.app.Fragment;
