Android: Make default holo button opaque

Question

By default, the buttons in ICS are a little bit transparent. I would like to accomplish that the button keeps all its properties (shape, color, state pressed), but than make it opaque.

How could I achieve that?

Thanks in advance!

Answer 1

You can create a style for the button extending the default style (if you are using Holo.Light):

<style name="GreenButton" parent="android:Widget.Holo.Button">
    <item name="android:background">#00ff00</item>
</style>

Then apply the style manually to the button with the style attribute or, if you want to change all buttons, set the buttonStyle in your app's theme:

<style name="AppTheme" parent="android:Theme.Holo">
    <item name="android:buttonStyle">@style/GreenButton</item>
</style>
