You can use the folder res to create specific layouts for Portrait or Landscape.

The briefcase layout inside the briefcase res, serves for generic layouts, without any "treatment", for any type of screen (resolution or orientation).

If you want to create a specific layout for Portrait, just create a folder layout-port inside your briefcase res. And to create a specific layout for Landscape, create a folder layout-land inside your briefcase res.

Note: don’t forget to keep the same name for both layouts in both folders.

In his Activity you don’t have to worry about which layout will be inflated, calling only setContentView(R.layout.seu_layout) and let Android take care of the rest
