I use a WebView to display my web pages .

You can create multiple layout folders in your res folder like this: layout-portrait, layout-landscape. Then you store different layouts in respective folders. Android is aware of what's the current orientation and it looks for a layout in the respective folder. Same way are the drawable-ldpi, drawable-mdpi and drawable-hdpi folders arranged. Hope this helps!

Each time the screen orientation is changing, the current activity in your app triggers the method onCreate(Bundle savedInstanceState) So you can decide to re-arrange your WebView by this way.

Then, detect the screen orientation : http://ykyuen.wordpress.com/2010/02/13/android-detect-the-phone-orientation/
