android 正则句子按照标点符号断句，正则Pattern；_android pattern 符号

  
        Pattern pattern = Pattern.compile("[,.?!;，。？！；]");//中括号需要；
        String[] split = pattern.split(content);

        Pattern pattern = Pattern.compile(regex);
        Matcher m = pattern.matcher(string);
 
        //这里是targetSdkVersion>28时的处理方法，其他情况查看Pattern源码
        while (m.find()) {
            //如果想去掉正则中的特殊字符，将“m.start() - 1”改成“m.start()”即可
            String match = input.subSequence(index, m.start() ).toString();
            matchList.add(match);
