php - 将数组传递给 BasicNameValuePair？

Question

我知道这听起来很疯狂，但我知道“BasicNameValuePair”实际上已被弃用!但我的老板告诉我出于某种原因要使用它。我有多个复选框，用户需要选择他们的兴趣，这些数据被发送并保存在 mysql 数据库中。我的问题是一切正常，但我只得到数据库中保存的最后一个被单击的值。尽管如此，我也尝试了“interests[]”，但这也没有帮助。

我选择兴趣的 Activity

}

}

我已经从我的 php“interestPage.php”文件成功建立了与数据库的连接。以及如何在 php 脚本中执行“interests”数组。我基本上使用 "switch ( $_POST['userInterests'] ) {......."

你设置了onCheckedChangedListener还是OnClickListener吗？
