Android API for sorting Chinese strings

Comparator comparator = Collator
     .getInstance(java.util.Locale.CHINA);
   Collections.sort(userRealNames, comparator);

//userRealNames is ArrayList<String>

Check Chinese characters

private static final boolean isChinese(char c) {
  Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
  if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
    || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
    || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
    || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
    || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
    || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
   return true;
  }
  return false;
