android 联系人表中有一个字段sort_key 大概是朱强 : ZHU 朱 QIANG 强

搜索策略 一般就是支持简拼、全拼、中文、号码和拨号盘

提供一种方法可以把简拼、全拼、中文可以放在一起处理，先把 “ZHU 朱 QIANG 强”

变成“ZHU 朱 QIANG 强 ZQ” 用下面的方法就可以一起处理了。

public class LongMain
{
    private static String sourceStr = "朱 ZHU 强 QIANG ZQ";
    
    private static String key = "朱强";
    
    private static String reg = "(.*\\b)?$z";
    
    // 优化：charAt()效率，StringBuffer
    public static void main(String[] args)
    {
        String regex = "";
        key = key.toUpperCase();
        for (int i = 0; i < key.length(); i++)
        {
            regex += reg.replace("$z", String.valueOf(key.charAt(i)));
        }
        regex = "^" + regex + ".*$";
        System.out.println(Pattern.compile(regex).matcher(sourceStr).matches());
    }
}

结果应该是 true

key换成是 ZQ、ZHUQIANG、Z、Q、朱、强 应该都是true 大概是满足搜索的过滤策略了

过滤完 以后可能还会涉及到关键字高亮的问题

下面提供3中方式：

1、第一种

Spanned style = Html.fromHtml(phone.replaceAll(input, "<font color='red'>" + input + "</font>"));
number_tv.setText(style);   

2、第二种

int index = phone.indexOf(input);
int len = input.length();
Spanned temp = Html.fromHtml(phone.substring(0, index)
          + "<font color=red>" + phone.substring(index, index + len)
          + "</font>" + phone.substring(index + len, phone.length()));
number_tv.setText(temp); 

3、第三种

int start = phone.indexOf(input);     
SpannableStringBuilder style=new SpannableStringBuilder(phone);     
style.setSpan(new ForegroundColorSpan(Color.RED), start, start + input.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
number_tv.setText(style);
