<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorWhite" android:state_checked="true">
        <set>
            <objectAnimator android:duration="0" android:propertyName="textSize" android:valueFrom="14" android:valueTo="16" android:valueType="floatType" />
        </set>
    </item>
    <item android:color="@color/colorBlack" android:state_checked="false">
        <set>
            <objectAnimator android:duration="0" android:propertyName="textSize" android:valueFrom="16" android:valueTo="14" android:valueType="floatType" />
        </set>
    </item>
</selector>

layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
