How to change android button text color globally in theme

 <style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">   <item name="android:textColor">#yourcolor</item>    <item name="android:buttonStyle">@style/ButtonColor</item>    <item name="colorButtonNormal">@color/buttonColor</item></style><style name="ButtonColor" parent="@android:style/Widget.Button">   <item name="android:textColor">@color/yourcolor</item></style> 

android:textColor This should help you change the text color globally.

For anyone that stumbles onto this, I recommend checking out a similar question about Material Design Button Styles. With a theme, your "accent color" will be used to color your button.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">    ...    <item name="android:buttonStyle">@style/Widget.AppCompat.Button.Colored</item>    <item name="buttonStyle">@style/Widget.AppCompat.Button.Colored</item></style>

With the new Theme.MaterialComponents theme you can define the materialButtonStyle attribute in your app theme.

  <!-- Base application theme. -->    <style name="AppTheme" parent="Theme.MaterialComponents.Light">    ....    <item name="materialButtonStyle">@style/MyButtonTheme</item>  </style>

In this way you can customize globally the style of all buttons in your app. You can override the theme attributes from the default style using the materialThemeOverlay attribute.

Something like:

  <style name="MyButtonTheme" parent="Widget.MaterialComponents.Button">    <item name="materialThemeOverlay">@style/ButtonStyleTextColor</item>  </style>  <style name="ButtonStyleTextColor">    <!-- For filled buttons, your theme's colorPrimary provides the default background color of the component, and -->    <!--the text color is colorOnPrimary -->    <item name="colorPrimary">@color/my_color</item>    <item name="colorOnPrimary">@color/my_color2</item>  </style>

Currently the materialThemeOverlay attribute requires version 1.1.0 of material components for android library.
