我的post_item.java文件中有以下代码：
package com.iwantnew.www;
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.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;

public class post_item extends Activity {
private ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();
Button add_room;
EditText contact_no;
EditText no_of_room;
EditText price_per_room;
EditText description;
private static String url_create_product = "http://10.0.2.2/android_iwant/android_add_room.php";
private static final String TAG_SUCCESS = "success";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.post_form);
//contact_no = (EditText) findViewById(R.id.contact_no);
no_of_room = (EditText) findViewById(R.id.no_of_room);
price_per_room = (EditText) findViewById(R.id.price_per_room);
//description = (EditText) findViewById(R.id.description);
contact_no = (EditText) findViewById(R.id.contact_no);
add_room = (Button) findViewById(R.id.add_room);
add_room.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// creating new product in background thread

});
}
// suru...
class add_new_room extends AsyncTask<String, String, String> {
/**

@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(post_item.this);
pDialog.setMessage("Saving details..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**

protected String doInBackground(String... args) {
//String contact = contact_no.getText().toString();
String quantity = no_of_room.getText().toString();
String price = price_per_room.getText().toString();
//String contact = contact_no.getText().toString();

// Building Parameters

// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_product,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), MainActivity.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();
}
}
}
而且，我的 php 文件中有以下内容：
<?php
/*
* Following code will create a new product row
* All product details are read from HTTP Post Request
*/
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['quantity']) && isset($_POST['price'])) {
//$location = $_POST['location'];
$quantity = $_POST['quantity'];
$price = $_POST['price'];
//$productID = $_POST['area'];
//$contact = $_POST['contact'];
$descriptions = $_POST['descriptions'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO room_tb(uid,categoryID,quantity,price,description) VALUES(5,1,'$quantity','$price','$descriptions')");
//$result1 = mysql_query("INSERT INTO users(userContactNumber) VALUES('$contact')");
// check if row inserted or not
if($result)/*&& ($result1)*/ {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Room added successfully.";
// echoing JSON response
echo json_encode($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);
}
?>
每当我将描述或联系电话发送到数据库时，android 模拟器都会说“意外停止工作”，并且没有记录进入数据库。但是，如果我只通过quantity、price、categoryID和uid，则不会发生错误并且记录会进入数据库。我究竟做错了什么？
