Android Theme style file merge

Issue

Describe my situation in short, I have a multi themes project with style.xml and style.xml(v21). The only difference of these two versions is that in each theme of v21 version has these two line in addition:
<item name="android:navigationBarColor">?attr/colorPrimaryDark</item> <item name="android:statusBarColor">?attr/colorPrimaryDark</item>

And I don't what two maintain two style files since they are too familiar, so is there any way I can merge these two style xml file ,or make the v21 one extends style.xml and when I what to make some modification, I only have to work with style.xml

Solution

Is this what you mean?

Place this in your "Normal" theme folder

<!--Standard-->
<style name="CommonTheme" parent="Theme.AppCompat.NoActionBar">
    <!--Place all common elements here-->
</style>

<!--Standard-->
<style name="AppTheme" parent="CommonTheme">

</style>

Place this in your V21 folder

<!--V21-->
<style name="AppTheme" parent="CommonTheme">
    <item name="android:navigationBarColor">?attr/colorPrimaryDark</item>
    <item name="android:statusBarColor">?attr/colorPrimaryDark</item>
</style>
