Change button background color in entire project in Android

Question

I'm making an Android app, but I cannot change the default background color of all buttons in the project.

The only way I can do it is by changing them one by one.

Is there any other way?

Set buttonStyle in your Theme.

like following: (I assume that you use AppCompat)

In your style.xml:

<resources>

    <style name="AppTheme" parent="Theme.AppCompat">
        ...
        <item name="buttonStyle">@style/YourButtonStyle</item>
        <!-- For preview -->
        <item name="android:buttonStyle">@style/YourButtonStyle</item>
    </style>

    <style name="YourButtonStyle" parent="@style/Widget.AppCompat.Button">
        <!-- Set background -->
        <item name="android:background">@drawable/your_button_drawable</item>
    </style>

</resources>

In your AndroidManifest.xml:

<application
     ...
    android:theme="@style/AppTheme" >
