Android实现中文按拼音排序方法

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

public class PinyinComparator implements Comparator { 
  /** 
   * 比较两个字符串 
   */ 
  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; 
  } 
 
  /** 
   * 将字符串中的中文转化为拼音,其他字符不变 
   * 
   * @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();// 把字符串转化成字符数组 
    String output = ""; 
 
    try { 
      for (int i = 0; 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());
