java - ANDROID 使用 AsyncTask MySQL 通过 JSON 更新 ListView

Question

沉浸在我的程序开发中，我遇到了一个在我看来并不是真的在说话的错误。

所以这是我的 logcat 顺序和 java 代码:

当我点击 ListView 中的项目时，它应该返回更新的联系信息。

public class  MajContactActivity extends Activity {

EditText txtNom;
EditText txtPrenom;
EditText txtNummobile;
EditText txtNumfixe;
EditText txtEmail;
EditText txtAdresse;
EditText txtProfession;

Button btnSav;
Button btnSup;

String idCONTACT;

// Progress Dialog
private ProgressDialog pDialog;

// JSON parser class
JSONParser jsonParser = new JSONParser();

// single contact url
private static final String url_detail_contact = "http://10.0.2.2/contactCloud/detail_contact.php";

// url to update contact
private static final String url_update_contact = "http://10.0.2.2/contactCloud/update_contact.php";

// url to delete contact
private static final String url_delete_contact = "http://10.0.2.2/contactCloud/delete_contact.php";

// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_CONTACT = "personne";
private static final String TAG_IDCONTACT = "idCONTACT";

private static final String TAG_NOM = "nom";
private static final String TAG_PRENOM = "prenom";
private static final String TAG_NUMMOBILE = "numero_mobile";
private static final String TAG_NUMFIXE = "numero_fixe";
private static final String TAG_EMAIL = "email";
private static final String TAG_ADRESSE = "adresse";
private static final String TAG_PROFESSION = "profession";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.maj_contact);

    // save button
    btnSav = (Button) findViewById(R.id.btnSav);
    btnSup = (Button) findViewById(R.id.btnSup);

    // getting contact details from intent
    Intent i = getIntent();

    // getting contact id (idCONTACT) from intent
    idCONTACT = i.getStringExtra(TAG_IDCONTACT);

    // Getting complete contact details in background thread
    new GetDetailContact().execute();

    // save button click event
    btnSav.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // starting background task to update contact
            new SavDetailContact().execute();
        }
    });

    // Delete button click event
    btnSup.setOnClickListener(new View.OnClickListener() {

        @Override

我没看到还是错了？

谢谢你的帮助!

试试这个..

您不能在 doInBackground 中进行初始化，您需要在 onCreate 中进行初始化。就像你不能在 doInBackground 中设置文本一样，需要在 onPostExecute 中设置。

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.maj_contact);

    // save button
    btnSav = (Button) findViewById(R.id.btnSav);
    btnSup = (Button) findViewById(R.id.btnSup);

    // Edit Text
                        txtNom = (EditText) findViewById(R.id.inputNom);
                        txtPrenom = (EditText) findViewById(R.id.inputPrenom);
                        txtNummobile = (EditText) findViewById(R.id.inputNumMobile);
                        txtNumfixe = (EditText) findViewById(R.id.inputNumFixe);
                        txtEmail = (EditText) findViewById(R.id.inputEmail);
                        txtAdresse = (EditText) findViewById(R.id.inputAdresse);
                        txtProfession = (EditText) findViewById(R.id.inputProfession);


    // getting contact details from intent
    Intent i = getIntent();

    // getting contact id (idCONTACT) from intent
    idCONTACT = i.getStringExtra(TAG_IDCONTACT);

    // Getting complete contact details in background thread
    new GetDetailContact().execute();

    // save button click event
    btnSav.setOnClickListener(new View.OnClickListener() {
