How do I apply a style to all buttons of an Android application

Question

I have a style applied to my whole application:

AndroidManifest.xml:

<application android:theme="@style/ApplicationStyle" android:icon="@drawable/icon" android:label="@string/app_name">

And in my styles.xml:

 <style name="ApplicationStyle" parent="android:Theme">
  <item name="android:button">@style/CKButton</item>
 </style>
 <style name="CKButton" parent="android:style/Widget.Button">
  <item name="android:textSize">19sp</item>
  <item name="android:layout_margin">0dip</item>
  <item name="android:background">#ff0000</item>
 </style>

But the style doesn't get applied.

I'm sorry if I just used the false name in the ApplicationStyle - Item, but I have no clue where to look for the object names and simply assumed, that android:button applies to all buttons.

Answer 1

For Android styles, you reference the preset attributes that Android has laid out in R.attr. In this case, it looks like you want to to reference android:buttonStyle. I think this would work:

<style name="ApplicationStyle" parent="android:Theme">
  <item name="android:buttonStyle">@style/CKButton</item>
</style>

God, I was looking for such functionality for ages. Got no idea why buttons' textColor does not follow main theme's textColor property. Thanks much! – Corso

any one no how to do this for spinner? – Tumescent

Just one note: if the CKButton style does not inherit @android:style/Widget.Button, the button will stop working. – Aret

what is difference between parent="android:Widget.Button" and parent=@android:style/Widget.Button? – Bibliotheca

Why layout editor do not preview changes as per the button style set in the theme – Secrecy

For Material components theme it would be like this:

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <item name="materialButtonStyle">@style/AppTheme.Button</item>
</style>
