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

Posted by: admin March 11, 2020 Leave a comment

Questions:

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 ApplicationStyleItem, but I have no clue where to look for the object names and simply assumed, that android:button applies to all buttons.

How to&Answers:

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>
