Try this

Add a selector.xml in drawable folder like

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/beyaz" android:state_enabled="true" />
<item android:color="@color/colorPrimaryDark" android:state_enabled="false" />
</selector>

In activity_main.xml add app:itemIconTint="@drawable/selector"

 <android.support.design.widget.BottomNavigationView

    app:itemIconTint="@drawable/selector"

    />
