onClick event in navigation drawer

I have made a navigation drawer in Android in which I want to implement onClick for it. This is my main activity:

public class MainActivity extends AppCompatActivity {

private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle aToggle;
private Toolbar toolbar;
private RecyclerView recyclerView;
private RecyclerAdapter recyclerAdapter;
private RecyclerView.Adapter adapter;
private NavigationView navigationView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
    aToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.navig, R.string.open, R.string.Close);
    navigationView = (NavigationView) findViewById(R.id.nav_view);
    mDrawerLayout.addDrawerListener(aToggle);
    toolbar = (Toolbar) findViewById(R.id.nav_action);
    toolbar.setNavigationIcon(R.drawable.navig);
    setSupportActionBar(toolbar);
    aToggle.syncState();
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    navigationView.setItemIconTintList(null);
    recyclerView = (RecyclerView) findViewById(R.id.recycler);
    recyclerAdapter = new RecyclerAdapter(getApplicationContext());
    RecyclerView.LayoutManager layoutManager = new GridLayoutManager(this, 2);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setAdapter(recyclerAdapter);


}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (aToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);

}}

This is my XML layout for the activity:

 <?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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.alpit.formula2.MainActivity">


    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginStart="0dp"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/recycler"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginTop="58dp"
            android:orientation="vertical"></android.support.v7.widget.RecyclerView>

        <android.support.v7.widget.Toolbar
            android:id="@+id/nav_action"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#EF6C00"
            android:orientation="vertical"
            android:theme="@style/ThemeOverlay.AppCompat.Dark"></android.support.v7.widget.Toolbar>


    </RelativeLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#FFA726"
        app:menu="@menu/navigation_menu"
        app:theme="@style/NavigationTheme">


    </android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>

This is my menu items:

    <group
        android:id="@+id/gp1"
        android:checkableBehavior="single">
        <item
            android:id="@+id/nav_maths"
            android:icon="@drawable/maths"
            android:title="Maths" />

        <item
            android:id="@+id/nav_physics"
            android:icon="@drawable/physics"
            android:title="Physics" />

        <item
            android:id="@+id/nav_chem"
            android:icon="@drawable/chem"
            android:title="Chemistry" />

        <item
            android:id="@+id/EEE"
            android:icon="@drawable/lightbulb"
            android:title="Electronics Electrical" />
    </group>

    <group
        android:id="@+id/gp2"
        android:checkableBehavior="single">
        <item
            android:id="@+id/unitconversion"
            android:icon="@drawable/unitconversion"
            android:title="Unit Conversion" />
        <item
            android:id="@+id/Scientist"
            android:icon="@drawable/scientist"
            android:title="Scientist" />


        <item
            android:id="@+id/favourite"
            android:icon="@drawable/favourite"
            android:title="Favourite" />
    </group>

    <group
        android:id="@+id/gp3"
        android:checkableBehavior="single">
        <item
            android:id="@+id/Share"
            android:icon="@drawable/share"
            android:title="Share" />
        <item
            android:id="@+id/Rate"
            android:icon="@drawable/rate"
            android:title="Rate" />
        <item
            android:id="@+id/ads"
            android:icon="@drawable/ad"
            android:title="Remove Ads" />
        <item
            android:id="@+id/aboutus"
            android:icon="@drawable/aboutus"
            android:title="About Us" />
    </group>
</menu>

The problem is I am not able to understand how to implement the onClick on the navigation drawer as it is populated by the list given by us not by any listView.

How can I implement onClick on the items of navigation drawer?

 binding.navigationView.setNavigationItemSelectedListener {
            when(it.itemId){
                R.id.book -> Toast.makeText(applicationContext, "Booked", Toast.LENGTH_SHORT).show()
            }

class MainActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    val nav_view: NavigationView = findViewById(R.id.nav_view)
    nav_view.setNavigationItemSelectedListener(this)
    nav_view.bringToFront();
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
    when(item.itemId){
        R.id.miid_log_out -> Toast.makeText(this, "Working", Toast.LENGTH_SHORT).show()
    }

Step-1: Extends the NavigationView.OnNavigationItemSelectedListener on your Activity Step2: Then there will show an error then override the method:

  @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        return false;
    }

get the Id with menuItem.getId() .And Perform Your Action as per your need.

final Step: Add This line in onCreate navigationView.setNavigationItemSelectedListener(this);

That's it.

You need to add implements NavigationView.OnNavigationItemSelectedListener

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener

and add method

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    // Handle navigation view item clicks here.
    switch (item.getItemId()) {

       case R.id.nav_maths: {
      //do somthing
            break;
        }  
    }
    //close navigation drawer
    mDrawerLayout.closeDrawer(GravityCompat.START);
    return true;
}

method to set Listener

private void setNavigationViewListener() {
    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}

call method in onCreate()

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setNavigationViewListener()
}

Below code is for adding toggle to DrawerLayout

 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);

And to add listener to Navigation menu items

implements NavigationView.OnNavigationItemSelectedListener

and override below method

@Override
  public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();
    if(id == R.id. nav_maths){
      //Handle your stuff here
    } 
}

Add below code to onCreate method

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);

in your

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (aToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);

}}

add these lines:

switch (item.getItemId()) {
    case R.id.nav_maths:
        // your logic here.
        return true;
    case R.id.nav_physics:
        //your logic here
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }

Add NavigationItemSelectedListener event to nav_view

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

Implement your Activity with NavigationView.OnNavigationItemSelectedListener

and add this code for click 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) {
        // Handle the camera action
    } 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;
}
