Question

I need to ‘hide’ the textSize parameter in BigButton style, inherited from Button. How to do so?

<style name="Button">
    <item name="android:background">@color/button_background</item>
    <item name="android:textColor">#FFFFFF</item>
    <item name="android:padding">5dp</item>
    <item name="android:textSize">@dimen/button_text_size</item>
</style>

<style name="BigButton" parent="@style/Button">
    <item name="android:textSize"></item>
</style>

Answer 1

Try

<style name="BigButton" parent="@style/Button">
    <item name="android:textSize">@null</item>
</style>
