BottomNavigationView with more than 3 Items: tab title is hiding

Question

I'm using BottomNavigationView with using Android Support Design Library 25. But when I switch the tabs, the other tab's title is hiding. But there is no hiding issue actual Bottom Navigation View. But mine is hiding.

But I want to it look like that. Any idea to do that? What am I missing?

Here is my code:

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.yunus.ototakip.MainActivity">

<FrameLayout
    android:id="@+id/main_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/bottom_navigation"
    android:layout_alignParentTop="true">
</FrameLayout>

<android.support.design.widget.BottomNavigationView
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    app:itemBackground="@color/colorPrimary"
    app:itemIconTint="@color/beyaz"
    app:itemTextColor="@color/beyaz"
    app:menu="@menu/bottombar_menu" />

bottom_bar_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
 <item
android:id="@+id/bb_menu_arac"
android:enabled="true"
android:icon="@drawable/icon_car"
android:title="@string/araclarim"
app:showAsAction="ifRoom" />
 <item
android:id="@+id/bb_menu_yakin"
android:enabled="true"
android:icon="@drawable/icon_yer"
android:title="@string/yakinimdakiler"
app:showAsAction="ifRoom" />
  <item
android:id="@+id/bb_menu_yaklasan"
android:enabled="true"
android:icon="@drawable/icon_takvim"
android:title="@string/yaklasanlar"
app:showAsAction="ifRoom" />

<item
    android:id="@+id/bb_menu_ipucu"
    android:enabled="true"
    android:icon="@drawable/icon_ipucu"
    android:title="@string/ipuclari"
    app:showAsAction="ifRoom" />
 </menu>

The solution using reflection doesn't work anymore because the field mShiftingMode was removed.

There's an easy way to do it now: Use Support Library 28 or higher and just add app:labelVisibilityMode="labeled" to your BottomNavigationView XML declaration.

Hope it helps.
