java - 在java android中替换字符 '@'

Question

我想将字符串中的字符 '@' 和 '.' 替换为 '_' 。我可以将 char '.' 替换为 '_' 但不能替换 char '@' .

public String getemailparsing(String email){
        String result="";
        char keong = 64;
        for(int i=0; i<email.length();i++){
            if(email.charAt(i) == '@' ){
                result = email.replace('@', '_'); //this is NOT working
            }else if(email.charAt(i) == '.'){
                result = email.replace('.', '_'); //this one is working
            }
        }
        return result;
    }

任何替换 char '@' 的想法 ...
