You should have two layout for both Landscape and Potrait and put your landscapelayout to layout-land and protrailayout to layout folder . Android will automatically do the rest of the things for you .

if you are in landscape or portrait Android looks for the layout file in either the -port or -land directory first, if it's not found then it falls back to the default layout directory.

you can read it here..http://developer.android.com/guide/topics/resources/providing-resources.html

Add this in your Manifest file in your activity for the fixed orientation you want for your Activity

android:screenOrientation="portrait"

like

<activity android:name=".Settings" android:label="@string/app_name" android:screenOrientation="portrait">
