字符串内逗号的新行

Question

我有一个EditText视图，它允许用户编辑地址字段。我想用一个逗号任何文本之前在新行被说得那么例如以下： Some St., Some City, Some post code会被显示为：

Some St., 
Some City, 
Some post code 

有谁知道我能做到这一点？

Answer 1

也许你可以执行String.replace()与,\n

所以更换所有逗号，

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

然后，您可能必须做一些事情来

或者删除空格，删除所有空白：

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];
