关于模糊匹配，我真的有点头大，我想到的是用正则表达式来做，但需要用到第三方类库pinyin4j.jar，我试了一下，效率都点低，明显感觉有点慢了，假如你的通讯录的量比较大，用这个来做确实不合时宜，或许可以进行优化的地方。

定义一个工具类

“[mno]”, “[pqrs]”, “[tuv]”, “[wxyz]” };

/**

*/

public static String getPingYin(String inputString) {

if (TextUtils.isEmpty(inputString)) {

return “”;

}

HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();

format.setCaseType(HanyuPinyinCaseType.LOWERCASE);

format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);

format.setVCharType(HanyuPinyinVCharType.WITH_V);

char[] input = inputString.trim().toCharArray();

String output = “”;

try {

for (int i = 0; i < input.length; i++) {

if (java.lang.Character.toString(input[i]).matches(

“[\u4E00-\u9FA5]+”)) {

String[] temp = PinyinHelper.toHanyuPinyinStringArray(

input[i], format);

if (temp == null || TextUtils.isEmpty(temp[0])) {

continue;

}

output += temp[0].replaceFirst(temp[0].substring(0, 1),

temp[0].substring(0, 1).toUpperCase());

} else

output += java.lang.Character.toString(input[i]);

}

} catch (Exception e) {

e.printStackTrace();

}

return output;

}

}

/**

public void search(String str){

contactList.clear();

//如果搜索条件以0 1 +开头则按号码搜索

if(str.toString().startsWith(“0”) || str.toString().startsWith(“1”)

contactList.add(model);

} else if(model.telnum.contains(str)){

}

}

adapter.refresh(contactList, false);

}

/**

Matcher matcher = pattern.matcher(model.pyname);

if(matcher.find()){

String tempStr = matcher.group();

for(int i = 0; i < tempStr.length(); i++){

return true;

}

//根据全拼查询

Matcher matcher = pattern.matcher(model.pyname);

boolean flag = matcher.find();

if(flag){

model.group = matcher.group();

}

return flag;

}

上面的代码是我从网上搜了很久才搜到的一个demo里面的代码，我整合到项目当中去，发现使用pinyin4j.jar类库效率实在有点低，所以我自己想了其他办法，不用第三方类库来实现。

下面是小巫的实现：

我找到一篇关于，中文字符转换为拼音的实现类，很有用
