Updating android styles to recognize material components

Question

I just recently change the parent reference of my AppTheme, to have compatibility with recent tools, but now some old styles are not been applied..

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

To

 <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">

And for example this button style is not working.

<style name="ButtonStyle" parent="@android:style/Widget.Button">
    <item name="android:background">@drawable/dark_bb</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textColor">@color/colorAccent</item>
</style>

Answer 1

When switching from Theme.AppCompat.Light.DarkActionBar to Theme.MaterialComponents.Light.DarkActionBar, update your button style like this:

<style name="ButtonStyle" parent="Widget.MaterialComponents.Button">
  <item name="backgroundTint">@drawable/dark_bb</item>
  <item name="android:textStyle">bold</item>
  <item name="android:textColor">@color/colorAccent</item>
</style>

Apply the style in your layout:

<Button
  style="@style/ButtonStyle"
  ...
/>

This ensures compatibility with Material Components theme.
