从 ArrayList> 取值
问题描述：
我在从 ArrayList 获取值时遇到问题.
I have a problem about getting a value from my ArrayList<HashMap<String, String>>.
我的代码是:
ArrayList<HashMap<String, String>> myArrayList;
然后:
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_ID, id);
map.put(TAG_NAME, name);
myArrayList.add(map);
例如，如果我想获取名称，我尝试了以下操作，但出现运行时错误(应用程序崩溃):
If I want to get the name, for example, I tried as follow but I obtain a runtime error (the application crashes):
System.out.println(myArrayList.get(1).get(TAG_NAME));
我该如何解决?
非常感谢！
答
System.out.println(myArrayList.get(1).get(TAG_NAME));
ArrayList 从 0 开始.get(0) 代替.
ArrayList is 0-based. get(0) instead.
