字符串中逗号的新行

Question

我有一个EditText视图，允许用户编辑地址字段。我希望任何带有逗号的文本放在新行之前，例如以下内容： Some St., Some City, Some post code将显示为：

Some St., 
Some City,
Some post code

任何人都知道我该怎么做？

Answer 1

也许您可以执行String.replace()将所有逗号替换为,\n

所以，

 String s = "Some St., Some City, Some post code"
 s = s.replace(",",",\n");

然后你可能需要做一些事情来删除空白

或者，删除所有空格：

    String s = "Some St., Some City, Some post code";
    String strings[] = s.split(",");

      for(int i = 0; i < strings.length; i++){
         strings[i] = strings[i].trim();
         strings[i] += ",\n";
      }
      s = "";

      for(int i = 0; i < strings.length; i++)
        s += strings[i];
