Android类似通讯录模糊匹配搜索实现（号码、首字母、简拼、全拼）

最近开发中有个需求类似qq搜索功能，根据数字，首字母，全拼，简拼实现数据检索。之前只是根据对象的属性来对比，后来发现有局限性，所以参考一篇博客自己动手修改了一下，实现的结果还比较不错的，在这里分享一下：

效果图1 简拼：

效果2 全拼：

效果3 根据数字搜索：

下面介绍关键的类：

一、中文字符转换为拼音的实现类

二、搜索的类

public class LocalGroupSearch {/** * 按群号-群名拼音搜索 *  * @param str */public static ArrayList<Group> searchGroup(CharSequence str,ArrayList<Group> allContacts) {ArrayList<Group> groupList = new ArrayList<Group>();// 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 (Group group : allContacts) {if (getGroupName(group) != null&& group.getRoomid() + "" != null) {if ((group.getRoomid() + "").contains(str)|| group.getNaturalName().contains(str)) {groupList.add(group);}}}return groupList;}CharacterParser finder = CharacterParser.getInstance();String result = "";for (Group group : allContacts) {// 先将输入的字符串转换为拼音finder.setResource(str.toString());result = finder.getSpelling();if (contains(group, result)) {groupList.add(group);} else if ((group.getRoomid() + "").contains(str)) {groupList.add(group);}}return groupList;}/** * 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 */private static boolean contains(Group group, String search) {if (TextUtils.isEmpty(group.getNaturalName())&& TextUtils.isEmpty(group.getRoomName())) {return false;}boolean flag = false;// 简拼匹配,如果输入在字符串长度大于6就不按首字母匹配了if (search.length() < 6) {String firstLetters = FirstLetterUtil.getFirstLetter(getGroupName(group));// 不区分大小写Pattern firstLetterMatcher = Pattern.compile(search,Pattern.CASE_INSENSITIVE);flag = firstLetterMatcher.matcher(firstLetters).find();}if (!flag) { // 如果简拼已经找到了，就不使用全拼了// 全拼匹配CharacterParser finder = CharacterParser.getInstance();finder.setResource(getGroupName(group));// 不区分大小写Pattern pattern2 = Pattern.compile(search, Pattern.CASE_INSENSITIVE);Matcher matcher2 = pattern2.matcher(finder.getSpelling());flag = matcher2.find();}return flag;}private static String getGroupName(Group group) {String strName = null;if (!TextUtils.isEmpty(group.getNaturalName())) {strName = group.getNaturalName();} else if (!TextUtils.isEmpty(group.getRoomName())) {strName = group.getRoomName();} else {strName = "";}return strName;}}

三、调用

/** * 搜索框监听 */TextWatcher textWatcher = new TextWatcher() {@Overridepublic void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {// TODO Auto-generated method stubif (s != null && s.length() > 0) {<span style="color:#ff00;">        </span>List<Group> listG = LocalGroupSearch.searchGroup(s, al);Logger.e(this, "local_group=" + listG.toString());TitledListView.FLAG_VIEW = true;FLAG_SHOW_TITLE = true;if (listG != null && listG.size() > 0) {} else {ToastUtil.show("搜索为空");}dAdapter.updateList(listG);searchUtils.showListView(dAdapter, null);Logger.e(this, "new_group=" + listG.toString());} else {FLAG_SHOW_TITLE = false;TitledListView.FLAG_VIEW = false;searchUtils.hideListView();dAdapter.updateList(al);}}@Overridepublic void beforeTextChanged(CharSequence arg0, int arg1, int arg2,int arg3) {}@Overridepublic void afterTextChanged(Editable arg0) {}};

搞定，代码量也不是很多，自己做个总结留个笔记，也希望可以帮助到朋友们。
