String 字符串去除特殊字符和空格，正则表达式使用，%1$s

特殊字符

String tt = "sdfdf{fwe }fwef< fwef #$";

String regEx="[`~!@#$%^&*()+=|{}':;'\\[\\].<>/?~！@#￥%……&*（）——+|{}【】'；：”“’。、？]";
Pattern p = Pattern.compile(regEx);
Matcher m = p.matcher(tt);
String toSpeechText=m.replaceAll("").trim();
Log.i("lgq","ww正则==="+toSpeechText);

Pattern pattern = Pattern.compile("\t|\r|\n|\\s*");
Matcher matcher = pattern.matcher(toSpeechText);
String dest = matcher.replaceAll("");

Log.i("lgq","ww正则222==="+dest);
