底部导航栏不显示图标

Question

I am initializing all of the icons with images but none of them are visible?

< ?xml version="1.0" encoding="utf-8"?>
 < menu xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/nav_item1"
        android:icon="@drawable/insta"
        app:showAsAction="ifRoom|withText"

        android:title="@string/nav1"/>
    <item
        android:id="@+id/nav_item2"
        android:icon="@drawable/artistsample"
        app:showAsAction="ifRoom|withText"
        android:title="@string/nav2"/>
    <item
        android:id="@+id/nav_item3"
        android:icon="@drawable/artistsample"
        app:showAsAction="ifRoom|withText"
        android:title="@string/nav3"/>
    <item
        android:id="@+id/nav_item4"
        android:icon="@drawable/artistsample"
        app:showAsAction="ifRoom|withText"

Can you please use the bellow code and see what happens.

and enable app:labelVisibilityMode="labeled" in BottomNavigationView
