Android Kotlin - Material Bottom Navigation Disable Shift Mode and Selete Menu

Question

I want to Disable Shift Mode with kotlin, I used material BottomNavigationView

 <com.google.android.material.bottomnavigation.BottomNavigationView
 android:id="@+id/bottom_navigation"
 android:layout_width="0dp"
 android:layout_height="wrap_content"
 android:layout_gravity="bottom"
 app:itemIconSize="@dimen/iconSize"
 android:background="?android:attr/windowBackground"
 app:layout_constraintBottom_toBottomOf="parent"
 app:layout_constraintEnd_toEndOf="parent"
 app:layout_constraintStart_toStartOf="parent"
 app:menu="@menu/btm_nav_menu"
 app:labelVisibilityMode="labeled"
 />

I want click account icon and start activity login when click back button homeFragment will be selected not account icon selected

bottom_navigation.setOnNavigationItemSelectedListener {
     when(it.itemId) {
         R.id.homeFragment -> showNav(HomeFragment())
         R.id.accountFragment -> { bottom_navigation.menu.findItem(R.id.homeFragment).setCheckable(true)
             startActivity(Intent(this, MainActivity2::class.java)) }
     }
     true
}


fun showNav(fragment: Fragment){ 
     supportFragmentManager.beginTransaction().apply {
           replace(R.id.fragment_container, fragment)
           commit()
     }
}

Can you explain better *"disable animate when click icon"*? – Gabriele Mariotti Aug 13 '20 at 07:24 — Gabriele Mariotti, Aug 13 '20 at 07:24
`app:labelVisibilityMode="labeled"` shoud be enough – Gabriele Mariotti Aug 13 '20 at 08:53 — Gabriele Mariotti, Aug 13 '20 at 08:53
Nope, Also text and icon bigger when click it, I don't want – TEN_KUNG Aug 13 '20 at 10:46 — TEN_KUNG, Aug 13 '20 at 10:46

Answer 2. Use false, Bottom Navigation will not select the icon

bottom_navigation.setOnNavigationItemSelectedListener {
        when(it.itemId) {
            R.id.homeFragment -> {
                showNav(HomeFragment())
                true
            }
            R.id.accountFragment -> {
                startActivity(Intent(this, MainActivity2::class.java))
                false
            } else -> true
        }
    }
