Android通讯录模糊匹配搜索实现（号码、首字母、简拼、全拼）

2013年12月10日 工作记录

小巫在工作中碰到一个需求，要求实现通讯录联系人的搜索，获取联系人的方式有好几种，我都有点混乱了，下面提供我最近用的一种，看起来还算比较简洁的，它是根据mimetypes表来查的。

// 查询所有联系人的姓名，电话，邮箱 public ArrayList<Contact> loadContacts() throws Exception {  Uri uri = Uri.parse("content://com.android.contacts/contacts");  ContentResolver resolver = this.getContentResolver();  Cursor cursor = resolver.query(uri, new String[] { "_id" }, null, null,    null);  ArrayList<Contact> contacts = new ArrayList<Contact>();  while (cursor.moveToNext()) {   Contact contact = new Contact();   int contractID = cursor.getInt(0);   StringBuilder sb = new StringBuilder("contractID=");   contact.setId(String.valueOf(contractID));   sb.append(contractID);   uri = Uri.parse("content://com.android.contacts/contacts/"     + contractID + "/data");   Cursor cursor1 = resolver.query(uri, new String[] { "mimetype",     "data1", "data2" }, null, null, null);   while (cursor1.moveToNext()) {    String data1 = cursor1.getString(cursor1      .getColumnIndex("data1"));    String mimeType = cursor1.getString(cursor1      .getColumnIndex("mimetype"));    if ("vnd.android.cursor.item/name".equals(mimeType)) { // 是姓名     contact.setName(data1);     sb.append(",name=" + data1);    } else if ("vnd.android.cursor.item/email_v2".equals(mimeType)) { // 邮箱     if (!TextUtils.isEmpty(data1)) {      contact.setEmail(data1);     }     contacts.add(contact);     sb.append(",email=" + data1);    } else if ("vnd.android.cursor.item/phone_v2".equals(mimeType)) { // 手机     contact.setNumber(data1.replaceAll("-", ""));     sb.append(",phone=" + data1);    }   }   contacts.add(contact);   cursor1.close();   Log.i("wwj", sb.toString());  }  cursor.close();  return contacts; }

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

package com.search;import net.sourceforge.pinyin4j.PinyinHelper;import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType;import android.provider.ContactsContract.CommonDataKinds.Phone;import android.text.TextUtils;public class BaseUtil { public final static String[] PHONES_PROJECTION = new String[] {   Phone.DISPLAY_NAME, Phone.NUMBER }; public static String STRS[] = { "", "", "[abc]", "[def]", "[ghi]", "[jkl]",   "[mno]", "[pqrs]", "[tuv]", "[wxyz]" }; /**  * 将字符串中的中文转化为拼音,其他字符不变  *   * @param inputString  * @return  */ 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; }}

/**  * 按号码-拼音搜索联系人  * @param str  */ 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")     || str.toString().startsWith("+")){   for(Model model : allContactList){    if(model.telnum.contains(str)){     model.group = str;     contactList.add(model);    }   }   adapter.refresh(contactList, false);   return;  }  StringBuffer sb = new StringBuffer();  //获取每一个数字对应的字母列表并以'-'隔开  for(int i = 0; i < str.length(); i++){   sb.append((str.charAt(i) <= '9' && str.charAt(i) >= '0')     ? BaseUtil.STRS[str.charAt(i) - '0'] : str.charAt(i));   if(i != str.length() - 1){    sb.append("-");   }  }    for(Model model : allContactList){   if(contains(sb.toString(), model, str)){    contactList.add(model);   } else if(model.telnum.contains(str)){    model.group = str;    contactList.add(model);   }  }  adapter.refresh(contactList, false);    }  /**  * 根据拼音搜索  * @param str   正则表达式  * @param pyName  拼音  * @param isIncludsive 搜索条件是否大于6个字符  * @return  */ public boolean contains(String str, Model model, String search){  if(TextUtils.isEmpty(model.pyname)){   return false;  }  model.group = "";  //搜索条件大于6个字符将不按拼音首字母查询  if(search.length() < 6){   //根据首字母进行模糊查询   Pattern pattern = Pattern.compile("^" + str.toUpperCase().replace("-", "[*+#a-z]*"));   Matcher matcher = pattern.matcher(model.pyname);      if(matcher.find()){    String tempStr = matcher.group();    for(int i = 0; i < tempStr.length(); i++){     if(tempStr.charAt(i) >= 'A' && tempStr.charAt(i) <= 'Z'){      model.group += tempStr.charAt(i);     }    }    return true;   }  }    //根据全拼查询  Pattern pattern = Pattern.compile(str.replace("-", ""), Pattern.CASE_INSENSITIVE);  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
