Change color of button with theme

Question

I have trouble in changing the background color and text color of my buttons in my app.

I made a new theme to play around and try it out. My manifest looks like this:

<application
    ...
    android:theme="@style/OrangeWhite">
    <activity android:name=".MainActivity">
    ...
</application>

My theme.xml looks like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="OrangeWhite" parent="android:Theme.Light">
        <item name="android:windowBackground">@color/OrangeWhite_bg_color</item>
        <item name="android:textColor">@color/OrangeWhite_wh_text</item>
        <item name="android:colorButtonNormal">@color/OrangeWhite_bg_btn</item>
    </style>

</resources>

Changing text or background color of an activity works just fine. The problem is the button. Do I need to specify on every button to use the theme OrangeWhite?...

If you are using AppCompat theme as parent than try below code

If you need to change the style of a specific button, you can define a new style, inheriting one of the parent styles described above. In the example below I just changed the background and font colors:

<style name="AppTheme.Button" parent="Widget.AppCompat.Button.Colored">
<item name="colorButtonNormal">@color/Red</item>
<item name="android:colorButtonNormal">@color/Red</item>
<item name="android:textColor">@color/White</item>
</style>

Then you just need to apply this new style on the button with:

android:theme="@style/AppTheme.Button"
