我正在尝试将一些值发送到我的数据库，但它不起作用。当我单击提交按钮时，它显示一个进度对话框，最后显示相同的页面。我已经为android 2.3.3编写了它 java代码是::
package donor.android.blooddonor;
import java.util.ArrayList;
import java.util.List;
import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONException;

import android.widget.Button;
import android.widget.EditText;
public class RegistrationActivity extends Activity{
private ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();

EditText et5;
EditText et6;
// url to create new product
private static String url_create_donor = "http://192.168.28.13/pro_connect/create_donor.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.registration);
// Edit Text
et1 = (EditText) findViewById (R.id.et1);

// Create button

// button click event

new CreateDonor1().execute();
}
});
}
class CreateDonor1 extends AsyncTask<String, String, String> {
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(RegistrationActivity.this);
pDialog.setMessage("Creating DONOR..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
protected String doInBackground(String... args) {
String NAME = et1.getText().toString();
String ADDRESS = et2.getText().toString();
String PHONENUMBER = et3.getText().toString();
String EMAIL = et4.getText().toString();
String CITY = et5.getText().toString();
String BLOODGROUP = et6.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("NAME", NAME));

params.add(new BasicNameValuePair("EMAIL", EMAIL));
params.add(new BasicNameValuePair("CITY", CITY));
params.add(new BasicNameValuePair("BLOODGROUP", BLOODGROUP));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_donor,
"POST", params);
Log.d("Create Response", json.toString());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created donor
Intent i = new Intent(getApplicationContext(), SearchDirectly1Activity.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
}
}

这是我的php文件：
<?php
/ * *以下代码将创建一个新的产品行 *所有产品详细信息均来自HTTP Post Request * /
//用于JSON响应的数组 $ response = array（）;
//检查必填字段 if（isset（$ _ POST ['NAME']）＆amp;＆amp; isset（$ _ POST ['ADDRESS']）＆amp;＆amp; isset（$ _ POST ['PHONENEUMBER']）＆amp;＆amp; isset（$ _ POST [' EMAIL']）＆amp;＆amp; isset（$ _ POST ['CITY']）＆amp;＆amp; isset（$ _ POST ['BLOODGROUP']））{
$name = $_POST['NAME'];
$address = $_POST['ADDRESS'];
$phonenumber = $_POST['PHONENUMBER'];
$email = $_POST['EMAIL'];
$city = $_POST['CITY'];
$bloodgroup = $_POST['BLOODGROUP'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO data5(id,name, bloodgroup, address, email, mobile, city) VALUES(0,'$name', '$bloodgroup', '$address', '$email', '$phonenumber', '$city')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "successfully registered.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
} ？＆GT;
答案 0 :(得分：0)
检查您的服务器是否返回了某些内容（TAG_SUCCESS值），如果是这种情况，您的php文件可能存在问题，或者您发送了错误的参数。
