Answer 1

Just use this code:

 public static boolean isRTL() {
   return isRTL(Locale.getDefault());
 }

 public static boolean isRTL(Locale locale) {
  final int directionality = Character.getDirectionality(locale.getDisplayName().charAt(0));
  return directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT ||
       directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT_ARABIC;
 }

 if (isRTL()) {
   // The view has RTL layout
 }
 else {
   // The view has LTR layout
 }

This will work for all Android API lavels.
