Use Same DrawerLayout and ActionBar In All Activities In Android Studio

In MainActivity, I've created a DrawerLayout and ActionBar. Is there any way to use that same Drawer and ActionBar in other activities without writing the same code again? Here's the code I'm using:
Main.xml:
<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:id="#+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:titleTextColor="#FFF"></androidx.appcompat.widget.Toolbar>
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#color/colorPrimary"
>
</androidx.constraintlayout.widget.ConstraintLayout>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/homepage_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
></androidx.recyclerview.widget.RecyclerView>
</LinearLayout>
<com.google.android.material.navigation.NavigationView
android:id="#+id/main_nav"
android:layout_width="277dp"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/header"
app:menu="#menu/drawer_menu"></com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
Main Java (I've Removed The Extra Code [Non Drawer-Actionbar Code]):
DrawerLayout drawerLayout;
Toolbar toolbar;
TextView json;
RequestQueue requestQueue;
ActionBarDrawerToggle actionBarDrawerToggle;
private RequestQueue mqueue;
private RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mqueue = Volley.newRequestQueue(this);
setuptools();
setUpToolbar();
}
private void setUpToolbar()
{
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.app_name,R.string.app_name) ;
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
toolbar.setNavigationIcon(R.drawable.ic_menu);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.right_menu,menu);
final MenuItem awesomeMenuItem = menu.findItem(R.id.notification_iconmain);
View awesomeActionView = awesomeMenuItem.getActionView();
awesomeActionView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(awesomeMenuItem);
}
});
final TextView not_num = (TextView) menu.findItem(R.id.notification_iconmain).getActionView().findViewById(R.id.hotlist_hot);
String username = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);
String server_url = "https://google.com/api/notifications.php?username="+username;
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, server_url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("results");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject notification_numbers = jsonArray.getJSONObject(i);
String final_num = notification_numbers.getString("notifications");
if(final_num.equals("0")){
}else{
not_num.setVisibility(View.VISIBLE);
not_num.setText(final_num);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}
);
mqueue.add(request);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.notification_iconmain){
Intent intent_noti = new Intent(this, NotificationsPage.class);
this.startActivity(intent_noti);
}
if(id == R.id.user_icon){
Intent intent_user = new Intent(this, Profile_Page.class);
this.startActivity(intent_user);
}
return super.onOptionsItemSelected(item);
}
}
What It Does:
It creates a slider drawer, an action bar with the right side menu, and displays the notification count on Bell Icon, and each item has its custom on-click event.
Now, how I can use the same drawer, action bar without writing the code again and again in each activity.

Displaying Fragments in My Application using Navigation Drawer?

I have three Fragments that I am trying to display by clicking the appropriate option from a Navigation Drawer. I have the Navigation Drawer displaying and opening/closing fine. But I can't get any of the Fragments to display in the Activity. The main screen just stays blank whenever I click an option. There are no compilation errors. I am new to Android development and also Java dev, and I've been trying to complete this project for a month so it will be finished as soon as I can get this to work. You may see some instances of redundant code, because I just wanted to try anything that could work and I am not sure what to delete, so any clarification on that would help too.
The Fragments should be displayed as results in a RecyclerView.

I have two other Fragments that I set up a little differently but just showing the one for ATMs because I feel it is the closest to working.

DrawerLayout NavigationView No drawer view found with gravity LEFT

I have implemented a drawer layout whereby when I click a navigation view item a tab layout opens up. The tablayout comes in fine but the problem is when i click the back button of the tab layout the application crashes with No drawer view found with gravity LEFT. Also I have noticed that there is a bit of a lag when the navigation drawer closes when the tab layout comes in, the drawer does not close smoothly.
Below is my java code and xml:

When I try to view activity_home.xml as a design it will not showing left drawer but when I install the app on device it will show the left drawer on click but when I click on any time it will not showing check able box and not working.

Update These lines of code works for me.. after update clean and rebuild Project.
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();

Here is a simple solution to address this issue. You can just link your HomeActivity methods to the menu items (whichever you want to). Now just create your methods and go to the menu layout. In the menu layout just add the android:onClick inside the item tag and put the particular method name inside it. And you are done. Let me know if this was useful.

Navigation Drawer Header how to put name and profile pic image from Google Sign in

I was able to make a navigation drawer and google sign in app using firebase tutorials from youtube https://www.youtube.com/playlist?list=PLGCjwl1RrtcR1j6EmpBxJyJYowK2QIsdT
I have activity_navigation.xml:

this is my navigation_activity.java
public class NavigationActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private Toolbar mToolbar;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
private TextView mName;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
mToolbar = findViewById(R.id.nav_action);
setSupportActionBar(mToolbar);
mDrawerLayout = findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,R.string.open,R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mAuth = FirebaseAuth.getInstance();
mAuthListener = new FirebaseAuth.AuthStateListener() {
#Override
public void onAuthStateChanged(#NonNull FirebaseAuth firebaseAuth) {
if(firebaseAuth.getCurrentUser() == null) {
startActivity(new Intent(NavigationActivity.this,MainActivity.class));
}
}
};
mName = mNavigationView.getHeaderView(0).findViewById(R.id.textView);
mPic = mNavigationView.getHeaderView(0).findViewById(R.id.pPic);
getCurrentinfo();
mNavigationView = findViewById(R.id.nav_view);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(final MenuItem menuItem) {
int id = menuItem.getItemId();
switch (id) {
case R.id.nav_account:
Toast.makeText(NavigationActivity.this, "Account Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.nav_settings:
Toast.makeText(NavigationActivity.this, "Setting Selected", Toast.LENGTH_SHORT).show();
default:
return true;
}
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private void getCurrentinfo() {
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null) {
for (UserInfo profile : user.getProviderData()) {
// Id of the provider (ex: google.com)
String providerId = profile.getProviderId();
// UID specific to the provider
String uid = profile.getUid();
// Name, email address, and profile photo Url
name = profile.getDisplayName();
photoUrl = profile.getPhotoUrl();
mName.setText(name);
Picasso.with(getApplicationContext())
.load(photoUrl.toString())
.placeholder(R.drawable.logo)
.resize(100, 100)
.transform(new CircleTransform())
.centerCrop()
.into(mPic);
}
}
}
}
in my getcurrentInfo function I am able to place my name and profile pic in the activity_navigation.xml but I want to place it an navigation_header.xml
I tried changing the id of my ImageView and TextView to match with that in the navigation_header but my app crashes.

Try this after mNavigationView = (NavigationView) findViewById(R.id.nav_view);
TextView userName = (TextView)mNavigationView.getHeaderView(0).findViewById(R.id.username);
It is because you are initializing the textview before the navigationview
get initialized
mName = (TextView)mNavigationView.getHeaderView(0).findViewById(R.id.textView);
mPic = (ImageView) mNavigationView.getHeaderView(0).findViewById(R.id.pPic);
getCurrentinfo();
mNavigationView = (NavigationView) findViewById(R.id.nav_view); //navigation view is initialized here

This is going to work 100% hopefully.
Let me know if it works.
`
//Initializing firebase objects
firebaseAuth = FirebaseAuth.getInstance();
firebaseUser = firebaseAuth.getCurrentUser();
//Go to your specific database directory or Child
databaseReference = FirebaseDatabase.getInstance().getReference().child("Students").child(firebaseUser.getUid());
//Connect the views of navigation bar
mNavigationView = (NavigationView) findViewById(R.id.nav_view);
mName = (TextView)mNavigationView.getHeaderView(0).findViewById(R.id.textViewHeaderTitle);
mID = (TextView)mNavigationView.getHeaderView(0).findViewById(R.id.textViewHeaderSID);
mImageView = (CircleImageView) mNavigationView.getHeaderView(0).findViewById(R.id.imageViewHeaderIcon);
//Use you DB reference object and add this method to access realtime data
databaseReference.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
//Fetch values from you database child and set it to the specific view object.
mName.setText(dataSnapshot.child("name").getValue().toString());
mID.setText(dataSnapshot.child("sid").getValue().toString());
String link =dataSnapshot.child("profile_picture").getValue().toString();
Picasso.with(getBaseContext()).load(link).into(mImageView);
}
//SIMPLE BRO. HAVE FUN IN ANDROID <3 GOOD LUCK
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
`

From NavigationView you will access the textview and imageview with "navigationView.getHeaderView(0)" this line
For Quick Sample
TextView userName = (TextView) navigationView.getHeaderView(0).findViewById(R.id.username);
userName.setText(new UserPreference().getUser(MainActivity.this).userName);
All the Best!!
