java单选按钮，按下“后退”按钮并再次按“后退”相同的活动
我有一个问题，我有一个活动，我正在显示一个列表视图，其中有不同用户的用户图像和单选按钮，当我选择单选按钮时，它被选中并切换到另一个。这是正常的，但问题是出现时，按下后退按钮，并返回相同的活动。当我按下“后退”按钮并再次在屏幕上显示相同的活动时，它在单选按钮上显示默认标记任何用户，大多数时候它都会出现在第一个位置。虽然我要标记不同的配置文件，但它将带有默认标记单选按钮和最近标记按钮。我尝试使用适配器1删除。notifyDataSetChanged（）然后清除所有可见性，但在执行操作时显示空白单选按钮，但执行操作但不显示我选择的单选按钮这里是我的代码`
