If you are a beginner, you might find the following useful(read up): Developing orientation aware Android apps
You probably have to define different layouts for landscape and portrait. You could force android to choose the proper layout depending on orientation. You could put landscape layout xml files in “res\layout-land” and portrait in “res\layout”. Of course it’s always good idea to use RelativeLayout, but it depends on your application. Regards!
