Question

I’m facing some problems with the progress dialogs. I use a managed progress dialog to show the user that an operation is being carried out with the following code written in the onCreateDialog(int id) function:

          case PROGRESS_DIALOG :
            {
                dialog = new ProgressDialog(this);                                      
                dialog.setMessage(getResources().getString(R.string.eStrUpdating));
                dialog.setCancelable(true);
                dialog.setOnCancelListener(new DialogInterface.OnCancelListener()
                {
                    public void onCancel(DialogInterface dialogInterface)
                    {
                       Log.i(TAG,"progress dialog cancelled ");
                    }
                });
                return dialog;
            }

When the operation completes I call dismissDialog(PROGRESS_DIALOG). The problem is that if I rotate the phone while the progress dialog is displayed then when the operation completes the dismiss call has no effect and the progress remains showing. And this I cannot understand why.

Answer 1

When you rotate the phone, the Activity is destroy and recreated. Then you should call dismiss on your dialog, in the onDestroy method of your activity and recreate it.
