android - 使用volley通过按钮将recyclerview中特定卡的数据存储在mysql中

Question

我正在开发使用 volley 获取数据并使用 recyclerview 在提要中显示的应用程序。我在每张卡中都有一个按钮，单击该按钮时，将计算点击次数并将其显示在该特定卡的 TextView 中(例如 instagram)像按钮)。现在，当单击按钮时，我希望点击的值也存储在与我的 mysql 数据库中卡中的其他项目同一行的列(喜欢)中。这是我尝试做的，但我没有得到它。有人可以帮忙吗？这是我的代码...

在多用户情况下，您必须将该特定卡(数据)ID 发送到服务器 b'z，这可能会发生许多用户喜欢相同的情况？

另一方面，在服务器端，当您收到请求时，从数据库获取计数并将其添加到其中并将该响应发送到您的设备并将其存储到数据库中，当您收到响应显示(例如向用户计数)时。
