drawer menu not doing anything on Click event

Iam Implementing navigation drawer in my application but its menu not working on click. I dont know whats wrong but on click event is not doing anything or toasting a message.Click anything from drawer menu dont do anything.Firstly other button were also not working but adding them in a seprate layout solved the issue.but drawer menu are still not working
Here is my xml :
<androidx.drawerlayout.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">
<com.google.android.material.navigation.NavigationView
android:id="#+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/drawer_menu" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include layout="#layout/app_bar_main" />
</LinearLayout>
</androidx.drawerlayout.widget.DrawerLayout>
Here in java Iam using it :
public class AuthorMainScreen extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
DrawerLayout drawerLayout;
NavigationView navigationView;
private ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_author_navigation);
viewDeclaration();
drawerLayout.addDrawerListener(actionBarDrawerToggle);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (actionBarDrawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
private void viewDeclaration() {
newSurveyBtn = findViewById(R.id.new_surveys_button);
surveyWithRef = findViewById(R.id.get_survey_button);
surveyResult = findViewById(R.id.analyze_survey);
drawerLayout = findViewById(R.id.drawer_layout);
navigationView = findViewById(R.id.navigation_view);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.menu_share:
System.out.println("ss" + "coming");
Toast.makeText(getApplicationContext(), "Share", Toast.LENGTH_SHORT).show();
break;
case R.id.menu_survey_count:
Toast.makeText(getApplicationContext(), "Surveys", Toast.LENGTH_SHORT).show();
break;
case R.id.menu_logout:
Toast.makeText(getApplicationContext(), "logout", Toast.LENGTH_SHORT).show();
break;
}
return true;
}

Solution for this is in the XML file bring navigation view below the include tag and it will work
Change this
<com.google.android.material.navigation.NavigationView
android:id="#+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/drawer_menu" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include layout="#layout/app_bar_main" />
</LinearLayout>
To this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include layout="#layout/app_bar_main" />
</LinearLayout>
<com.google.android.material.navigation.NavigationView
android:id="#+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/drawer_menu" />

You don't initialize actionBarDrawerToggle. You have to do it.

When you are using AndroidX try to use the methods related to it.
Add the host fragment when you want to implement the fragments in that particular activity:
xml:
<androidx.drawerlayout.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">
<fragment
android:id="#+id/host_fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"
app:navGraph="#navigation/navigation_graph"
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="0dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include layout="#layout/app_bar_main" />
</LinearLayout>
<com.google.android.material.navigation.NavigationView
android:id="#+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/drawer_menu" />
Now use the navigation graph where you need to implement the fragments you are about to use in the activity :
navigation_graph.xml:
<?xml version="1.0" encoding="utf-8"?>
<navigation 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/navigation_graph"
app:startDestination="#id/profile">
<fragment
android:id="#+id/profile"
android:name="com.example.jetpacknavigationexample.Fragments.ProfileFragment"
android:label="#string/profile"
tools:layout="#layout/fragment_profile" />
<fragment
android:id="#+id/features"
android:name="com.example.jetpacknavigationexample.Fragments.FeaturesFragment"
android:label="#string/features"
tools:layout="#layout/fragment_features" />
<fragment
android:id="#+id/signout"
android:name="com.example.jetpacknavigationexample.Fragments.ProfileFragment"
android:label="#string/signout"
tools:layout="#layout/fragment_signout" />
</navigation>
In your java class add the implement the Navigation component code :
public class AuthorMainScreen extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
DrawerLayout drawerLayout;
NavigationView navigationView;
private ActionBarDrawerToggle actionBarDrawerToggle;
//Add this
NavController mNavController;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_author_navigation);
//add this
mNavController = Navigation.findNavController(this,R.id.host_fragment);
NavigationUI.setupActionBarWithNavController(this, mNavController, drawerLayout);
NavigationUI.setupWithNavController(navigationView,mNavController);
mNavigationView.setNavigationItemSelectedListener(this);
viewDeclaration();
drawerLayout.addDrawerListener(actionBarDrawerToggle);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (actionBarDrawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
private void viewDeclaration() {
newSurveyBtn = findViewById(R.id.new_surveys_button);
surveyWithRef = findViewById(R.id.get_survey_button);
surveyResult = findViewById(R.id.analyze_survey);
drawerLayout = findViewById(R.id.drawer_layout);
navigationView = findViewById(R.id.navigation_view);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.menu_share:
System.out.println("ss" + "coming");
Toast.makeText(getApplicationContext(), "Share",
Toast.LENGTH_SHORT).show();
break;
case R.id.menu_survey_count:
Toast.makeText(getApplicationContext(), "Surveys",
Toast.LENGTH_SHORT).show();
break;
case R.id.menu_logout:
Toast.makeText(getApplicationContext(), "logout",
Toast.LENGTH_SHORT).show();
break;
}
return true;
}
You can test your app now. let me know after you implement this.

FindViewByID from another layout

I have a problem.
I create a DrawerLayout and I use it as my MainLayout.
For my menu, I create a nav_header with two TextView.
Of course, when I try to modify the TextView, I got a null object reference, because the TextView are from another layout.
How can I setText for the TextView from another layout (specifically nav_header)?
I tried LayoutInflate but the problem doesn't disappear (probably i set things bad).
Can anyone help me?
MainActivity.java:
public class MainActivity extends AppCompatActivity{
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private NavigationView navigationView;
private TextView logout_txt, name_txt;
private PermissionManager permissionManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final LayoutInflater layoutInflater = getLayoutInflater();
final View view = layoutInflater.inflate(R.layout.nav_header, null);
Log.d("USERNAME: ", ParseUser.getCurrentUser().getUsername());
name_txt = view.findViewById(R.id.txt_username_view);
name_txt.setText(ParseUser.getCurrentUser().getUsername());
ParseInstallation.getCurrentInstallation().saveInBackground();
init();
setUpDrawerContent(navigationView);
}
private void init() {
mDrawerLayout = findViewById(R.id.drawer_layout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
navigationView = findViewById(R.id.nav_view);
logout_txt = findViewById(R.id.logout);
permissionManager = new PermissionManager() {};
permissionManager.checkAndRequestPermissions(this);
name_txt.setText(ParseUser.getCurrentUser().getUsername());
}
Nav_header.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="160dp"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:background="#drawable/main_header_selector"
android:padding="15dp"
tools:context=".MainActivity">
<ImageView
android:src="#drawable/ic_account"
android:layout_width="75dp"
android:layout_height="75dp" />
<TextView
android:id="#+id/txt_username_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name"
android:textColor="#color/white"
android:textStyle="bold"
android:textSize="20sp" />
<TextView
android:id="#+id/txt_email"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="12red.hawk12#gmail.com"
android:textColor="#color/white"
android:paddingTop="5dp"/>
</LinearLayout>
UPDATE:
I tried this code, and the applications starts, but the setText doesn't set text.

You are using a wrong method to use the drawerlayout. You could simply use the Navigation Drawer Activity in Android Studio for creating a navigation drawer. Navigation Drawer Layout automatically creates 4 layout files and a Java file for this purpose. I'm adding them right bellow-
MainActivity.java

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);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

Navigation Drawer, Main activity content is not showing

When I add a Button or TextView it crashes. Actually I am new to android programming. I have searched a lot and found that the content of nav drawer activity should be put in content_** folder. In the same way I put a text view in content_main2.xml and it crashes. I put it in the FrameLayout and this time it also crashes.please help me out.
This is My Main2activity.java

And finally I decided not to use fragments then I saw a tutorial NAV DRAWER on every activity without fragment.I created a new nav activity named test and put a TextView in it.it is working but When I add a button it crashes.
contetnt_test.xml

start coding in FirstFragment's layout because you are replacing content_main2.xml to FirstFragment's layout.
May be it will help you.

You can edit like this app_bar.main2.xml
<?xml version="1.0" encoding="utf-8"?>

First of all, your layout should be like this:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:id="#+id/appBar_layout">
<android.support.v7.widget.Toolbar
.....
..../>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
Secondly, in order for the tabs to work, you need to use a ViewPager Adapater, andd then use tabs.setupWithViewPager().
I recommend you look at this tutorial to help you.

Navigation drawer with diff fragment

I am using android default navigation drawer and i want that same layout for all the activities i tried searching on internet i got some ideas for customized drawer but not on android studio default drawer. Kindly help me.
navigation drawer.class :
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
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);
}
app_main.xml:

android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
Here in app_bar_main layout i would like to change that
include layout="#layout/content_main" with my activity or fragment so that i can have the same layout.
Thanks in advance.

Create an Activity containing only NavigationDrawer and after that OnItemSelected from NavigationDrawer call every activity you want. Then NavigationDrawer will be available in all the activities.
The other solution is create MainActivity with NavigationDrawer and create other Fragments instead of Activities. Call those Fragmnets OnItemSelected from NavigationDrawer. There are alot of example available there.
Edit
In your activity where you have defined navigationDrawer, do the following. And instead of creating new activities for next layouts, create fragments and call them on OnItemSelected on navigationDrawer like below:
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.drawer_home:
Intent intent=new Intent(HomeActivity.this, HomeActivity.class);
startActivity(intent);
overridePendingTransition(0, 0);
finish();
return true;
// For rest of the options we just show a toast on click
case R.id.drawer_artist:
android.support.v4.app.FragmentManager fragmentManager=getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.content_frame, new ArtistsFragment());
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
return true;
default:
Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show();
return true;
}
}
});
Fragment code will be like:
public class ArtistsFragment extends Fragment {
public ArtistsFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootview= inflater.inflate(R.layout.fragment_artists, container, false);
return rootview;
}}
