一个电话本中联系人名字搜索高亮的实现

一个电话本中联系人名字搜索高亮的实现


需求：实现电话本名字搜索功能的高亮实现，其中搜索支持中文、简拼、全拼搜索，对搜索匹配到的名字部分高亮显示。




例如：


名字：张向东


全拼：zhangxiangdong


简拼：zxd


搜索匹配优先规则：中文（直接匹配）、简拼匹配、全拼匹配


关键在全拼匹配上面，比方用户输入gd，则匹配向东两个字，同xiangdong的匹配项




搜索功能通过数据库的搜索匹配实现，也就是输入是搜索的输入字符串mInputStr和搜索的名字结果列表List<User>

得到搜索的字符串在名字中匹配的开始位置和结束位置后，就可以设置高亮了：
    /**

     * 
     * @param color
     *            变化的色值
     * @param text
     *            文字
     * @param keyword
     *            文字中的关键字
     * @return
     */
    public static SpannableString matcherSearchTitle(int color, String text,
            String keyword) {
        SpannableString s = new SpannableString(text);
        Pattern p = Pattern.compile(keyword);
        Matcher m = p.matcher(s);
        while (m.find()) {
            int start = m.start();
            int end = m.end();
            s.setSpan(new ForegroundColorSpan(color), start, end,
                    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        return s;
    }

第二版：

主要对于全拼匹配的部分做了一个优化，第一版本对有几个汉字有约束，并且最大支持5个汉字，扩展性不好，第二版本改进了这个问题，用循环的方式实现；这样的改进也算是对思路的一个梳理。
