Answer 1

You can get the screen orientation (for example in your onResume() Method) like this:

private static final int ORIENTATION_0 = 0;
private static final int ORIENTATION_90 = 3;
private static final int ORIENTATION_270 = 1;





Display display = ((WindowManager)
          getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int screenOrientation = display.getRotation();

switch (screenOrientation)
{
default:
case ORIENTATION_0: // Portrait
   // do smth.
break;
case ORIENTATION_90: // Landscape right
   // do smth.
break;
case ORIENTATION_270: // Landscape left
   // do smth.
break;
}
