我得到了 Data As 插入但不是确切的用户输入。请告诉我哪里出错了。

看起来像这样:

    nameValuePairs.add(new BasicNameValuePair("fooditem", "fooditem"));
    nameValuePairs.add(new BasicNameValuePair("Date", "Date"));
    nameValuePairs.add(new BasicNameValuePair("Time", "Time"));

应该是这样的:

    nameValuePairs.add(new BasicNameValuePair("fooditem", fooditem));
    nameValuePairs.add(new BasicNameValuePair("Date", Date));
    nameValuePairs.add(new BasicNameValuePair("Time", Time));
