How to add click event to item on NavigationView of Android

Question

I am trying to implement Sidebar NavigationDrawer in my Android project. To do so, I have used NavigationView in DrawerLayout. To show items I used menu. I want to add click event on that added menu items.

Code for reference: In navigation menu -

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/nav_account" android:title="My Account"/>
    <item android:id="@+id/nav_settings" android:title="Settings"/>
    <item android:id="@+id/nav_layout" android:title="Log Out"/>
</menu>

In View:

<android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@menu/navigation_menu"
        android:layout_gravity="start" />

I wanted to make sure the Solution from Nizam can be found in Kotlin to, since it is takeing bigger place every day:

val mDrawerLayout = this.findViewById(R.id.drawer_layout) as DrawerLayout

val mNavigationView = findViewById<View>(R.id.navigation) as NavigationView

Handle the navigation items in onCreate like this:

mNavigationView.setNavigationItemSelectedListener { it: MenuItem ->
                when (it.itemId) {
                    R.id.nav_item1 -> doThis()
                    R.id.nav_item2-> doThat()
                    else -> {
                        true
                    }
                }
            }

Remember: Return Type has to be a boolean!
