Value equals to match_parent or fill_parent in dimens.xml?
Use this, it works for me
<dimen name="custom_wrap_content">-2px</dimen> <dimen name="horizontal_border_height">@dimen /custom_wrap_content</dimen><dimen name="custom_match_parent">-1px</dimen> <dimen name="vertical_border_height">@dimen /custom_match_parent</dimen>
And the Reason why match_parent
doesn't run. You cannot supply a build in keyword like match_parent
Edit: Use px
instead of dp
as suggested by Jarett Millard in the comments.
First create attribs.xml:
<resources> <item name="match_parent" type="dimen">-1</item> <item name="wrap_content" type="dimen">-2</item></resources>
Second use your dimens:
<dimen name="account_width">@dimen/match_parent</dimen> <dimen name="account_height">@dimen/wrap_content</dimen>
Depending on why you want to define match_parent
in a @dimen, this use case could help you:
Instead of defining the width and height in dimen.xml, you can define it as a style in the styles.xml
I use
//res/values/styles.xml<style name="IntroLayout"> <item name="android:layout_width">match_parent</item> <item name="android:layout_height">wrap_content</item></style>
and
//res/values-sw600dp/styles.xml<style name="IntroLayout"> <item name="android:layout_width">520dp</item> <item name="android:layout_height">wrap_content</item></style>
and use it like
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_gravity="center" style="@style/IntroLayout">
which allows me to dynamically set the width and height attributes for different sized devices without having to write any code and you can use match_parent/wrap_content fine. you can use any @dimen that you have defined previously in the style as well if you want.
I use this because the layout for phone and tablet is the same, except i want to fix the width on tablet but fill the parent on phone, so it saves having to have 2 different layouts with basically the same xml
