Question

I made a dialog with builder.setSingleChoiceItem with array of items that a user can choose from. But when a user adds something to that array, the list in that dialog is not updated, showing the previous list.

I read that you need to recreate the dialog in order to achieve this goal. How do you recreate it? How do you destroy the dialog and recreate its content all over again? so that you can refresh the list?

Thanks a lot for your answer in advance.

I found the answer

    @Override
    public void onPrepareDialog(int id, Dialog dialog) 
    {
        switch(id) 
        {
//name of the case of the dialog you want to REFRESH -meaning destroy and recreate
            case REMOVE_WATCH_WORD :
                removeDialog(REMOVE_WATCH_WORD);
                break;

        }
     }

I found a way to do this. In order to recreate your dialog every time in order to refresh everything, title, list, array, everything in the dialog, remove your dialog in onPrepareDialog. This will allow ALL the values to be reset, because onCreate dialog will be called again. This is the best, easy way solve this.
