我得到的数据作为插入，但没有确切的用户输入。 请告诉我我哪里错了。

看起来是这样的：

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));
