Android theme not being set -

i have theme refuses applied activities - none of styles applied. if don't supply layout_width/layout_height attributes <button> gets runtime error, showing button class isn't being applied.

/res/values/themes.xml:

<?xml version="1.0" encoding="utf-8"?> <resources>     <style name="theme" parent="android:style/theme.black">         <item name="android:windownotitle">true</item>         <item name="android:buttonstyle">@style/button</item>         <item name="android:windowbackground">@color/page_background_light</item>         <item name="android:textappearance">@style/textappearance</item>     </style> </resources> 

/res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?> <resources>     <style name="textappearance" parent="@android:style/textappearance">         <item name="android:textsize">12sp</item>         <item name="android:textcolor">@color/darkblue</item>     </style>     <style name="button" parent="@android:style/widget.button">         <item name="android:layout_width">fill_parent</item>          <item name="android:layout_height">wrap_content</item>         <!--<item name="android:textcolor">#3c2f4f</item>         <item name="android:textsize">20dip</item>-->     </style> </resources> 

and relevant manifest setting:

<application android:icon="@drawable/icon"     android:label="@string/app_name"     android:theme="@style/theme"> 

what's obvious mistake i'm missing?

i've been struggling well, , think i've found may have been problem - perhaps same.

i had custom theme defined in res\values folder, not in values-v11 , values-v14 folders. think made in devices (specially 2 testing with!), theme not applied because did not exist.

i see properties set in custom theme (applied @ application level) taking effect.
