Question

I have code to set a different layout for portrait and landscape. Is there a way to change the layout while the activity is running, if the user flips the device?

Code to set layout

void SetView()
{
   int w=getWindowManager().getDefaultDisplay().getWidth();
   int h=getWindowManager().getDefaultDisplay().getHeight();

   if (w>h)
      setContentView(R.layout.mainHor);
   else
      setContentView(R.layout.mainVer);
}

Make two new folders in res called layout-land and layout-port. Put your landscape layout in layout-land and your portrait in layout-port. Make sure the xml files have the same name.

Also, as was mentioned in the comments, making just the layout-land folder is good enough as long as you also have a default xml for the Activity in the layout folder. If for any reason Android can’t find the layout needed in the alternative layout-[orientation] folder, it will take what it finds in layout.
