Android: inheritance of components in xml

I have 5 buttons on my activity that differ each other only with value height:

    <Button
    android:id="@+id/someName"
    android:layout_width="170dp"
    android:layout_height="70dp"
    android:layout_marginTop="10dp"
    android:text="@string/some_text" />

    ... other buttons...

Is it possible to extends 4 buttons from first one and change only one of their property?
I know it is possible for styles, but what with components?
Or maybe should i do this in java code, but then how to connect to specific class?
