先将汉字转拼音，用到pingyin4j工具类

匹配工具类主要涉及字符串拼接，拆分（匹配方法可以优化使用KMP模式匹配算法，有空优化。。。）
//Utils.java/*** Search for the corresponding Chinese characters.* @param name name* @param keyWord keyWord*/public static SpannableStringBuilder stringSearch(String name, String keyWord) {String[] pinyin = Pingyin4jUtils.stringToPinyin(name, true, "/");startIndex = -1;endIndex = -1;//flag判断是不是索引字符串的开头flag = true;SpannableStringBuilder builder = new SpannableStringBuilder();builder.append(name);StringBuilder stringBuilder = new StringBuilder();for (int i = 0; i < pinyin.length; i++) {stringBuilder = getPinyinItem(pinyin[i], keyWord, stringBuilder, i);//当字符串包含keyword时说明已找到，记录endindexif (stringBuilder.toString().contains(keyWord)) {endIndex = i ;if (startIndex == -1) {startIndex = i;}UILog.i(TAG, "startIndex = " + startIndex + "endIndex = " + endIndex);builder.setSpan(new ForegroundColorSpan(ThemeManager.get().getColor(mon_txt_red)), startIndex, endIndex+1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);break;}}return builder;}/*** Traversing and splicing Chinese Pinyin.* @param pinyin pinyin* @param keyWord keyWord* @param stringBuilder stringBuilder* @param i i*/private static StringBuilder getPinyinItem(String pinyin, String keyWord, StringBuilder stringBuilder, int i) {//有/说明是多音字if (pinyin.contains("/")) {String[] pingitem = pinyin.split("/");UILog.i(TAG, "pingitem = "+ Arrays.toString(pingitem));StringBuilder temp = new StringBuilder();temp.append(stringBuilder);for (String s : pingitem) {//如果包含关键字则进行拼接，并记录位置if (keyWord.contains(s)||temp.append(s).toString().contains(keyWord)) {if (flag) {startIndex = i;flag = false;}stringBuilder.append(s);break;} else {flag = true;}}} else {if ((keyWord.contains(pinyin) || pinyin.contains(keyWord)) && flag) {startIndex = i;flag = false;} else if (!keyWord.contains(pinyin) && !pinyin.contains(keyWord)) {flag = true;}stringBuilder.append(pinyin);}return stringBuilder;}
使用方法：
SpannableStringBuilder builder = Utils.stringSearch(name, keyWord);mName.setText(builder);
