Android 无法从ArrayList获取正确的值<；HashMap<；字符串，字符串>&燃气轮机；
我正在尝试从Android 无法从ArrayList获取正确的值<；HashMap<；字符串，字符串>&燃气轮机；,android,arraylist,hashmap,Android,Arraylist,Hashmap,我正在尝试从ArrayList获取我的SharedReferences的数据。当我试图在AsynTask中获取数据时，它以正确的值形式给出ArrayList但当我试图从相同的ArrayList中获取值时，它会给出不同的值。在AsynTask预订id中，值是24和25，但在供应商接受信息（）方法它给出预订id25和25的值。我不知道24岁怎么变成25岁命名约定。 HashMap<String, String> app_detail = new HashMap<String, S

那么为什么我在vendor\u accept\u info（）
HashMap<String, String> app_detail = new HashMap<String, String>();
这肯定能解决你的问题
您正在使用全局HashMap
这就是为什么您的HashMap
值得到覆盖，并且在for循环中得到最后一个值2次的原因。。。您的代码是一场噩梦，有与方法同名的变量。。。太难读了！请清理您的代码（现代IDE将为您提供提示和工具），并向我们展示问题的最低但足够的版本，而不是所有代码。请使用公共类Clinet_通知-->命名约定。
HashMap<String, String> app_detail = new HashMap<String, String>();
for (int i = 0 ; i<jArry.length();i++){
HashMap<String, String> app_detail = new HashMap<String, String>();
// your code
applist.add(app_detail);
}
