Android Implements Sorting Chinese by Phonetic

The requirement of this article is to sort a set of data by Chinese phonetic in a field and share it with you in Android to implement Chinese phonetic sorting method for your reference. The details are as follows:
1. Test test class:

PinyinComparator comparator = new PinyinComparator(); 
    Collections.sort(strList, comparator); 

There is data in strList, which can be any object, but to modify compare in PinyinComparator, I have String in Demo [].

2. PinyinComparator Sort Class:

public class PinyinComparator implements Comparator<Object> { 
  /** 
   *  Compare two strings  
   */ 
  public int compare(Object o1, Object o2) { 
    String[] name1 = (String[]) o1; 
    String[] name2 = (String[]) o2; 
    String str1 = getPingYin(name1[0]); 
    String str2 = getPingYin(name2[0]); 
    int flag = str1.compareTo(str2); 
    return flag; 
  } 
 
  /** 
   *  Convert Chinese into Pinyin in a string , Other characters unchanged  
   * 
   * @param inputString 
   * @return 
   */ 
  public String getPingYin(String inputString) { 
    HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat(); 
    format.setCaseType(HanyuPinyinCaseType.LOWERCASE); 
    format.setToneType(HanyuPinyinToneType.WITHOUT_TONE); 
    format.setVCharType(HanyuPinyinVCharType.WITH_V); 
 
    char[] input = inputString.trim().toCharArray();//  Converts a string to an array of characters  
    String output = ""; 
 
    try { 
      for (int i = 0; i < input.length; i++) { 
        // \\u4E00 yes unicode Encoding to determine if it is Chinese  
        if (java.lang.Character.toString(input[i]).matches( 
            "[\\u4E00-\\u9FA5]+")) { 
          //  Save the whole spelling of Chinese Pinyin to temp array  
          String[] temp = PinyinHelper.toHanyuPinyinStringArray( 
              input[i], format); 
          //  Phonetic number 1 Pronunciation  
          output += temp[0]; 
        } 
        //  Convert uppercase letters to lowercase letters  
        else if (input[i] > 'A' && input[i] < 'Z') { 
          output += java.lang.Character.toString(input[i]); 
          output = output.toLowerCase(); 
        } 
        output += java.lang.Character.toString(input[i]); 
      } 
    } catch (Exception e) { 
      Log.e("Exception", e.toString()); 
    } 
    return output; 
  } 
}
