当我尝试更改任何项目的状态时：

我试图从数据库中选择项目并获取他们的ID来更改imageview。但它总是会获得最后的物品价值，这会导致一切都像最后一样。

以下是以下代码：

Answer 1

while (rs.next() && rs.first()) {


                        Map<String, String> datanum = new HashMap<String, String>();

                        datanum.put("A", rs.getString("Id"));
                        datanum.put("B", rs.getString("OdaNo"));
                        datanum.put("C", rs.getString("bolId"));
                        datanum.put("D", rs.getString("Durum"));
                        prolist.add(datanum);


                        s = datanum.get("D");



                    }
