using runOnUiThread в AlertDialog

У меня есть диалоговое окно с предупреждением, где при нажатии кнопки я делаю вызов webservice в отдельном потоке, а затем я хочу обновить некоторый интерфейс для потока пользовательского интерфейса, но runOnUiThread в AlertDialog не определен, как я могу сделай это ?using runOnUiThread в AlertDialog

Я также пробовал использовать runOnUiThread с контекстом активности владельца AlertDialog. но я получаю сообщение об ошибке, которое отправляется после кода. вот мой код

public class RecordDialog extends Dialog implements OnClickListener { 
Button recordButton; 

/* 
* param context 
*/ 

String requestResponse=""; 
int progIndex=0; 
public static String sessionId = ""; 
public static String programId = ""; 
public static String channelId = "";

Context cont; 

public RecordDialog(Context context) { 
    super(context); 
    cont= context; 
    /** 'Window.FEATURE_NO_TITLE' - Used to hide the title */ 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    /** Design the dialog in main.xml file */ 
    setContentView(R.layout.record_dialog); 
    recordButton = (Button) findViewById(R.id.recordBtn); 
    recordButton.setOnClickListener(this); 
    sessionId = SuccessLogin.userId; 
    handler = new Handler() { 
     @Override 
     public void handleMessage(Message msg) { 
      // process incoming messages here 
      switch (msg.what) { 
      // ///normal - just update message shown on progress dialog 
      case 0: 
       // update progress bar 
       // serviceClient.myprogress.setMessage("" +(String) 
       // msg.obj); 
       break; 
      // normal - cancel the dialog and update the UI 
      case 1: 

       break; 
      // error - may be due to bad settings, or bad response from 

      case 2: 
       // serviceClient.myprogress.cancel(); 
       // AlertDialog alert = ServerNotResponding((String) 
       // msg.obj);

Вы пытались передать контекст активности непосредственно к нему (например define final Activity this.getOwnerActivity(); перед запуском())? – sandrstar

все еще очень неясно, что вы делаете, отправляйте весь класс –

Почему вы не используете AsyncTask? – Egor

Вы пытались использовать андроид AsyncTask? Это намного эффективнее, чем стандартная Java-версия. Он также имеет метод onPostExecute, который выполняется в потоке пользовательского интерфейса после завершения основной задачи и должен позволить вам обновлять элементы пользовательского интерфейса. link

using asynchTask решил мою проблему, спасибо :) – Munazza

Вы получаете исключение nullPointerException: - может быть из двух причин: - 1. ProgressDialog, принимающий значение null, без заселения - это беспорядок. поэтому проверить

  if(progressDialog!=null){ 
     mProgressDialog = ProgressDialog.show(RecordDialog.this.getContext(), 
      "Please wait....", "Recording Program....", true); 
    mProgressDialog.setCancelable(true); 
    }

2.Or alertdialog имеет нулевое значение. & Try: -

   Activity.runOnUiThread(new Runnable() { 
          public void run() { 
           AlerDialog(); 
          } 
         });

Изменение ниже части кода. Если вы сделали ProgressDialog нулевым. И вы пытаетесь показать alertdialog в основном потоке. Попробуйте, как показано ниже:

Сначала инициализировать ProgressDialog в конструкторе, как показано ниже:

 private ProgressDialog mProgressDialog = null; 
    public RecordDialog(Context context) { 
      super(context); 
      cont= context; 
     mProgressDialog = ProgressDialog.show(RecordDialog.this.getContext(), 
      "Please wait....", "Recording Program....", true); 
     }

После вышеуказанные изменения запустить AlertDialog в runOnUiThread, как показано ниже:

private Runnable invalidRes = new Runnable() { 
    public void run() { 
     mProgressDialog.dismiss(); 
    } 
    }; 
    private Runnable retRes = new Runnable() { 
     public void run() { 
     mProgressDialog.dismiss(); 
     GuideActivity.progs.get(progIndex).isRecordingRequested="true"; 
     if(requestResponse.equals("Program Recording Started")) 
     { 
      recordButton.setBackgroundResource(R.drawable.record_already_btn_background); 
      Log.v("Program Recording Started", "Program Recording Started"); 
      //Toast.makeText(RecordDialog.this.getContext(), "Program Recording Started.", Toast.LENGTH_LONG).show(); 

      Activity.runOnUiThread(new Runnable() { 
       public void run() { 

       AlertDialog.Builder builder = new AlertDialog.Builder(
        RecordDialog.this.getContext()); 
       builder.setTitle(""); 
      builder.setMessage("Program Recording Started"); 
       builder.setPositiveButton("Ok", 
        new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, 
           int which) { 
        dialog.dismiss(); 
          } 
        }); 

      builder.create().show(); 
       } 
      }); 
     } 
     else 
      if(requestResponse.equals("UPR ERROR-CODE :: ALREADY REQUESTED")) 
      { 
       Log.v("Program Recording Started", "Program Recording Started"); 
       //Toast.makeText(RecordDialog.this.getContext(), "Program Recording ALREADY REQUESTED", Toast.LENGTH_LONG).show(); 

       Activity.runOnUiThread(new Runnable() { 
        public void run() { 

         AlertDialog.Builder builder = new AlertDialog.Builder(
         RecordDialog.this.getContext()); 
        builder.setTitle(""); 
       builder.setMessage("Program Recording ALREADY REQUESTED"); 
       builder.setPositiveButton("Ok", 
         new DialogInterface.OnClickListener() { 
          public void onClick(
            DialogInterface dialog, 
            int which) { 
            dialog.dismiss(); 
          } 
        }); 
      builder.create().show(); 
       } 
      }); 
      } 
    } 
};
