---------------------------------------------------------------------我都无语了，怎么回事呢

boolean b = m.matches();     //这一句不要，错误的；
正确的代码这样写，你试试：
String str ="我的手机是18511866260,我曾用过18987654321,还用过18812345678";  //不用String[ ]看看
     String regex ="[1][358][0-9]{6}(\\d){3}";
     Pattern p = Pattern.compile(regex);
     Matcher m = p.matcher(str);
     boolean b = m.matches();
     while(m.find()){
            System.out.println(m.group());}
     }
