私はまだAndroid開発には新しく、ユーザーを登録して情報をオンラインサーバーに保存するアプリケーションを作成しようとしていますが、次のエラーが発生します。JSONException：型java.lang.Stringの値require_onceをJSONObjectに変換できません

は私のJavaコードです：
public class RegistrationActivity extends AppCompatActivity implements View.OnClickListener{
private static final String TAG = RegistrationActivity.class.getSimpleName();;
private Button btnRegister;
private EditText inputName, inputEmail, inputPassword;

inputPassword = (EditText) findViewById(R.id.etPassword);
btnRegister = (Button) findViewById(R.id.btnRegister);
login = (TextView)findViewById(R.id.tvLogin);
login.setOnClickListener(this);
btnRegister.setOnClickListener(this);
progressDialog = new ProgressDialog(this);
progressDialog.setCancelable(false);
db = new SQLiteHandler(getApplicationContext());
// Session manager
session = new Session(getApplicationContext());
// Check if user is already logged in or not
if (session.isLoggedIn()) {
// User is already logged in. Take him to main activity
startActivity(new Intent(RegistrationActivity.this, MainActivity.class));
finish();
}
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.btnRegister:
String name = inputName.getText().toString().trim();

}
break;
case R.id.tvLogin:
startActivity(new Intent(RegistrationActivity.this, LoginActivity.class));
finish();
break;
default:
}
}
/**

private void registerUser(final String name, final String email,
final String password) {
// Tag used to cancel the request

}
} catch (JSONException e) {

}
}
}, new Response.ErrorListener() {
@Override

hideDialog();
}
}) {
@Override

}
private void showDialog() {
if (!progressDialog.isShowing())

そして、ここでは私のPHPコードです：
require_once 'include/DB_Functions.php';
$db = new DB_Functions();
// json response array
$response = array("error" => FALSE);
if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['password'])) {
// receiving the post params
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];
// check if user is already existed with the same email
if ($db->isUserExisted($email)) {
// user already existed
$response["error"] = TRUE;
$response["error_msg"] = "User already existed with " . $email;
echo json_encode($response);
} else {
// create a new user
$user = $db->storeUser($name, $email, $password);
if ($user) {
// user stored successfully
$response["error"] = FALSE;
$response["uid"] = $user["unique_id"];
$response["user"]["name"] = $user["name"];
$response["user"]["email"] = $user["email"];
$response["user"]["created_at"] = $user["created_at"];
$response["user"]["updated_at"] = $user["updated_at"];
echo json_encode($response);
} else {
// user failed to store
$response["error"] = TRUE;
$response["error_msg"] = "Unknown error occurred in registration!";
echo json_encode($response);
}
}
} else {
$response["error"] = TRUE;
$response["error_msg"] = "Required parameters (name, email or password) is missing!";
echo json_encode($response);
}
?>
どのように私はこのエラーを修正については行くようにしてください？ありがとうございます：D
あなたのウェブサーバから生のPHPが返送されています。実行していません。 –
これがなぜ起こっているのかに関する提案はありますか？ –
正しく設定していないためです。 –
