android - 使用Volley通过按钮从recyclerview中的特定卡中将数据存储在mysql中

我正在开发一个应用程序，该应用程序使用排球来获取数据并使用recyclerview.feed在提要中显示。我在每个卡中都有一个按钮，当单击该按钮时，它将计算点击次数并在该卡中的文本视图中显示它（例如instagram之类的按钮） 。现在，我希望将单击的值也存储在我的mysql数据库中卡中其他项的同一行中的一列（赞）中。这是我尝试执行的操作，但是我不明白。有人可以帮忙吗？这是我的代码...

最佳答案

在多用户情况下，您必须将特定的卡（数据）ID发送到服务器b'z，这可能会发生很多用户都喜欢相同的情况吗？

另一方面，在服务器端，当您收到请求时，从db获取计数并将其添加到其中，然后将响应发送到您的设备，并将其存储到db中，并且当您获得诸如count的响应显示给用户时。
