我的Android應用程序出現問題。我正在嘗試讓用戶在應用程序中填寫表單，並將其回覆發送到Google在線表單，並將回覆記錄在Google電子表格中。在應用程序本身中一切似乎都很好，我在那裏沒有遇到任何錯誤，但只有時間戳顯示在響應電子表格中，並且沒有文本。Android應用程序 - 將數據發佈到Google表單
這是我的POSTDATA方法的代碼：
public void postData(){
String url = getString(R.string.post_URL);
String name = "testname";
Log.i("test",name);
String lunch = "testlunch";
Log.i("test", lunch);
String vegetarian="testveg";
Log.i("test",vegetarian);
String allergies = "testaler";
Log.i("test",allergies);
String special = "testspec";
Log.i("test",special);
HttpRequest request = new HttpRequest();
try {
String data = R.string.entry_name + URLEncoder.encode(name, "UTF-8") + "&" +
R.string.entry_lunch + URLEncoder.encode(lunch, "UTF-8") + "&" +
R.string.entry_vegetarian + URLEncoder.encode(vegetarian, "UTF-8") + "&" +
R.string.entry_allergies + URLEncoder.encode(allergies, "UTF-8") + "&" +
R.string.entry_special + URLEncoder.encode(special,"UTF-8");
String response = request.sendPost(url,data);
Log.i("response",response);
}
catch(UnsupportedEncodingException e){
Log.d("Unsupported exception", e.toString());
}}
我使用谷歌的形式，此網址：
https://docs.google.com/forms/d/1XPaQe0j86XwcxbO13uxZRawCwUexyJMHdPlPLoQaD1A/formResponse
針對這些項目，我使用此格式的字符串：
entry.569049980
這是我如何調用該函數（只是暫時的）：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new Connection().execute();
}
private class Connection extends AsyncTask {
@Override
protected Object doInBackground(Object...arg0){
postData();
return null;
}
的HttpRequest的文件，我使用的是來自here

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.params.ClientPNames;

我需要使用的驅動器API或我可以做一些修改，以使這項工作？ （這似乎更容易，我根本沒有使用Drive API的經驗）
