android - Value equals to match_parent or fill_parent in dimens.xml? -

based on here on xml attributes section specify following in dimens.xml:

<dimen name="match_parent">-1dp</dimen> <dimen name="main_left_menu_user_account_width">@dimen/match_parent</dimen> <dimen name="main_left_menu_user_account_height">@dimen/match_parent</dimen> 

then use both dimensions in layout:

<imageview      android:id="@+id/useraccountimage"     android:background="@drawable/user_account"     android:layout_width="@dimen/main_left_menu_user_account_width"     android:layout_height="@dimen/main_left_menu_user_account_height" /> 

then, when preview graphical layout, complains:

you must supply layout_width attribute.

you must supply layout_height attribute.

actually can define value equals match_parent in dimens.xml?

update:

i tried preview still complains:

<dimen name="main_left_menu_user_account_width">-1dp</dimen> <dimen name="main_left_menu_user_account_height">-1dp</dimen> 

i use wrap_content (the graphical layout doesn't complain @ all):

<dimen name="wrap_content">-2dp</dimen>  <dimen name="main_right_menu_width">@dimen/wrap_content</dimen> <dimen name="main_right_menu_height">@dimen/wrap_content</dimen> 

use this, works me

<dimen name="custom_wrap_content">-2dp</dimen>   <dimen name="horizontal_border_height">@dimen /custom_wrap_content</dimen>  <dimen name="custom_match_parent">-1dp</dimen>   <dimen name="vertical_border_height">@dimen /custom_match_parent</dimen> 

and reason why match_parent doesn't run. you cannot supply build in keyword match_parent
