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());}
}
