You need to read up on the activity lifecycle: http://developer.android.com/guide/components/activities.html#Lifecycle When you rotate your device your activity is completely shut down and then re-created. Thus, by default, it gets put in the same state as when you first launch the app. To compensate for this, you need to override and implement the onSaveInstanceState() and onRestoreInstanceState() methods to put your activity in the same state it was before the rotation occurred. http://developer.android.com/reference/android/app/Activity.html#onSaveInstanceState%28android.os.Bundle%29 http://developer.android.com/reference/android/app/Activity.html#onRestoreInstanceState%28android.os.Bundle%29 Thanks, Justin Anderson MagouyaWare Developer http://sites.google.com/site/magouyaware On Sun, Jun 24, 2012 at 7:10 AM, StSch <[email protected]>wrote: > Can I please point you to my question on Stack Overflow? > > > http://stackoverflow.com/questions/11175966/how-to-prevent-the-layout-from-getting-reset-when-the-screen-orientation-changes > > I am a bit stuck.
