我是开发android应用程序的新手。我需要将 ID 存储在 WAMP 服务器中。当我尝试运行我的代码时,模拟器显示“不幸的是我的应用程序已停止”消息,我无法将数据从 android 发送到 PHP。
在过去的两天里,我正在尝试解决这个问题。我将我的活动添加到清单文件中。这是我的 .java 文件:
public class MainActivity extends Activity {
private ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();
EditText inputid;
private static String url_sample = "http://localhost/android_connect/sample.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Edit Text
inputid = (EditText) findViewById(R.id.editText1);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
// creating new product in background thread
new add().execute();
}
});
}
class add extends AsyncTask<String, String,String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("your Registration is processing..wait for few sec..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
protected String doInBackground(String... args) {
String id = inputid.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("id",id));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_sample, "POST", params);
// check log cat for 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 = getIntent();
setResult(100,i);
// closing this screen
finish();
} else {
// failed to create product
}
}
catch (Exception e) {
e.printStackTrace();
}
return doInBackground();
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
}
}
PHP代码是:
<?php
$response = array();
if (isset($_POST['id']))
{
$userid = $_POST['id'];
require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();
$result = mysql_query("INSERT INTO id(ID) VALUES('$userid')");
echo $userid;
if ($result)
{
$response["success"] = 1;
$response["message"] = " Registered successfully";
echo json_encode($response);
}
else
{
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
echo json_encode($response);
}
}
else
{
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
echo json_encode($response);
}
?>
PHP 和 Android 编码都没有错误..logcat 显示错误消息..有些是
