Using FILL_PARENT in dimensions.xml

Question

I have a View which width must depend on the screen width:

I was hoping I could use dimensions stored in XML files:

mylayout.xml:

 <View
   android:layout_height="100dip"
   android:layout_width="@dimen/myview_width"/>

values-sw600dp/dimensions.xml:

    <dimen name="myview_width">600dip</dimen>

values/dimensions.xml:

    <dimen name="myview_width">FILL_PARENT</dimen> <!-- NOT SUPPORTED -->

... but the use of FILL_PARENT is not supported in dimen elements.

What's the cleanest way to achieve this in XML ?

`fill_parent` and `match_parent` are the exact same thing, it's really not the issue here. — Sébastien, Jan 19 '14 at 18:59
You can check this answer http://stackoverflow.com/a/19043952/341998 . In a nutshell, it says that you can use -1 for match_parent and -2 for wrap_content. — Bracadabra, Jan 19 '14 at 19:00

You should use styles for different screens. Like this:

 <View
   style="@style/MyStyle"
   android:layout_height="100dip"/>

in values-sw600dp/my_style.xml:

    <style name="MyStyle">
        <item name="android:layout_width">600dip</item>
    </style>

in values/my_style.xml:

    <style name="MyStyle">
        <item name="android:layout_width">match_parent</item>
    </style>

With this you can do what you want.

It is considered bad practice to embed layout properties in style definitions. – Moritz Nov 17 '14 at 21:35
