Android 使用改装和viewmodel的微调器值
我正试图在我的项目中实现编辑购物车。为此，我使用了旋转器。我发布了两种方法：一种是使用viewmodel，另一种是不使用viewmodel。当我不使用viewmodel时，它可以正常工作。问题在于使用viewmodel时 在不使用viewmodel的情况下，它在调用中发布正确的值，在我重新访问购物车时在微调器中正确设置值，但是在使用viewmodel时，如果我将微调器设置为3，则显示成功，但在重新访问时，我在微调器中看到8，甚至在我使用Postman发出的其余请求中，我在响应中看到8 适配器：：------------Android 使用改装和viewmodel的微调器值,android,kotlin,spinner,viewmodel,android-spinner,Android,Kotlin,Spinner,Viewmodel,Android Spinner,我正试图在我的项目中实现编辑购物车。为此，我使用了旋转器。我发布了两种方法：一种是使用viewmodel，另一种是不使用viewmodel。当我不使用viewmodel时，它可以正常工作。问题在于使用viewmodel时 在不使用viewmodel的情况下，它在调用中发布正确的值，在我重新访问购物车时在微调器中正确设置值，但是在使用viewmodel时，如果我将微调器设置为3，则显示成功，但在重新访问时，我在微调器中看到8，甚至在我使用Postman发出的其余请求中，我在响应中看到8 适配器：：
