У меня проблема с моим alertdialog

Question

Я создал два действия: первый содержит подробную информацию о задании на работу, а следующий - постулировать на эту работу. после подачи заявки на работу появляется предупреждающий сигнал, подтверждающий успешность операции. Однако этот alertdialog появляется в представлении сведений о задании без значений! Как я могу управлять этим? Это деятельность 1:

private static final String MY_PREFERENCES = "mespreferences";

Answer 1

Используйте следующие действия для оповещения Dialog. Дайте более подробную информацию, чтобы понять ваши требования.

public void Alert(String text, String title) 
    { 
     AlertDialog dialog=new AlertDialog.Builder(context).create(); 
     dialog.setTitle(title); 
     dialog.setMessage(text); 
     if(!title.equals("") && !text.equals("")) 
     { 
      dialog.setButton("OK", 
        new DialogInterface.OnClickListener() 
        { 
         public void onClick(DialogInterface dialog, int whichButton) 
         { 
          // 
         } 
        }); 
      dialog.setButton2("Cancel", 
        new DialogInterface.OnClickListener() 
        { 
         public void onClick(DialogInterface dialog, int whichButton) 
         { 
          // 
         } 
        }); 
     } 

     dialog.show(); 

    }
