Dimen.xml below the values folder

<Resources>    <!--Default screen margins, per the Android Design guidelines. -    <dimenname= "Btn_width">16dp</dimen>    <dimenname= "Btn_height">16dp</dimen></Resources>

Use in layouts:

< Button    Android:text = "@string/test_dimen1"    android:id= "@+id/button01"   android:layout_width= "@dimen/btn_width"     android:layout_height= "@dimen/btn_height"/>

Folder meaning:

values-v11-------API 11+ stands for Android 3.0 +, meaning dimens.xml in this directory on API11 devices instead of Res/values/dimens.xml

values-480x320, values-800x480, etc.------------means that under different resolutions, the Dimens.xml in this directory is replaced by Res/values/dimens.xml
