我有我的活動一個問題，即必須從UI添加數據使用PHP文件數據的基礎上： 這是我的活動Java代碼：使用PHP文件，將數據添加到一個PostgreSQL數據庫的Android
import HttpManager.HttpManager;
import android.R.string;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class RapportActivity extends Activity {
// Progress Dialog
private ProgressDialog pDialog;
String params;
JSONParser jsonParser = new JSONParser();
EditText inputCode;
EditText inputLibelle;
EditText inputDescription;
EditText inputEtat;
EditText inputAction;
// url to create new product
private static String url_create_rapport = "http://10.0.2.2/Scripts/Create_rapport.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile);
// Edit Text
inputCode = (EditText) findViewById(R.id.textView1);
inputLibelle = (EditText) findViewById(R.id.textView2);
inputDescription = (EditText) findViewById(R.id.textView3);
inputEtat = (EditText) findViewById(R.id.textView4);
inputAction = (EditText) findViewById(R.id.textView5);
// Create button
Button btnCreateRapport = (Button) findViewById(R.id.button1);
// button click event
btnCreateRapport.setOnClickListener(new View.OnClickListener() {
String a;
String b;
String c;
String d;
String e;
@Override
public void onClick(View view) {
a=inputCode.getText().toString();
b=inputLibelle.getText().toString();
c=inputDescription.getText().toString();
d=inputEtat.getText().toString();
e=inputAction.getText().toString();
params="code="+a
+"&lib="+b
+"&desc="+c
+"&State="+d
+"&action="+c;
CreateNewRapport t1= new CreateNewRapport();
t1.execute(url_create_rapport,params);
}
});
}
/**
* Background Async Task to Create new product
* */
class CreateNewRapport extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(RapportActivity.this);
pDialog.setMessage("Creating Rapport..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
protected String doInBackground(String... params) {
String s = HttpManager.posdata(params[0], params[1]);
return s;
}
protected void onPostExecute(String s) {
super.onPostExecute(s);
Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
}
}
}
這是XML文件的代碼：

，這是我的PHP文件的代碼：
<?php
// array for JSON response
$response = array();
$hostname_localhost ='localhost';
$port_localhost =5432;
$database_localhost ='techmobi';
$username_localhost ='openpg';
$password_localhost ='openpgpwd';
$localhost = "host='$hostname_localhost' port='$port_localhost' dbname='$database_localhost' user='$username_localhost' password='$password_localhost'";
$code_tech = $_REQUEST['code'];
$lib_int = $_REQUEST['lib'];
$desc_int = $_REQUEST['desc'];
$etat_int = $_REQUEST['State'];
$action = $_REQUEST['action'];
$connexion =pg_connect($localhost) or die ("Erreur de connexion ".pg_last_error());
$query_search = "insert into rapport values('$code_tech','$lib_int','$desc_int','$etat_int','$action');";
$query_exec = pg_query($query_search) or die(pg_error());
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "requette successfully created.";
// echoing JSON response
echo json_encode($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);
}
?>
當我運行我的應用我上了logcat的那些錯誤：
請幫助！
