    <item >

With the new release v23.0.0 of the AppCompat library it is now possible to create Material Design Buttons for Lollipop and Pre-Lollipop devices.

If you just want to define the color of all Buttons you can set a special theme property called colorButtonNormal:

Add this line to your parent theme under styles.xml

<item name="colorButtonNormal">@color/yourColor</item>

for more information refer this

EDIT:

Making custom theme for button will do the trick.

<style name="CustomTheme" parent="Widget.AppCompat.Button.Colored">
    <item name="colorButtonNormal">@color/yourcolor</item>
</style>

and in use this like.

<Button android:theme="@style/CustomTheme"/>

Note: make sure you are using Widget.AppCompat.Button.Colored as parent.

Happy Coding..
