How Do You Change The Background Color of All Buttons?

Question

In the XML files on Android Studio, I created a theme for my app and wondering how to change all the button background colors in my theme in API 10? Here's what I got so far:

//Colors for certain widgets
  <color name="textView_Color">#505050</color>
  <color name="Button_Color">#878787</color>
  <color name="Background_Color">#ffffff</color>

//Where I assign the colors
<style name="mainTheme" parent="android:Theme.NoTitleBar">
  <item name="android:textColor">@color/textView_Color</item>
  <item name="android:         ">@color/Button_Color</item>
  <item name="android:windowBackground">@color/Background_Color</item>
</style>
