Removing view when clicked, how to solve?

I noticed I was doing this in my code:

ResultButton = new Button( theActivity );
    ButtonUtils.setButtonValues( ... );

    ((ViewGroup) (theActivity).findViewById( android.R.id.content )).addView(   ResultButton );

    ResultButton.setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View arg0) {
                         doStuff();


            ((ViewGroup) (getActivity()).findViewById( android.R.id.content )).removeView( ResultButton );

        }
    });

That seems clearly wrong, to remove itself inside its OnClickListener. But what is the right way to deal with these things. Since there is no main method in an Android program I cannot just set a flag and then have it deal with it later. You never really remove things? You just set them to invisible?

Inside your onClick implementation, the argument that you didn't rename corresponds to the view that triggered the event, you can call the parent of said view and ask it to remove the said child view. 

ViewGroup parentView = (ViewGroup) view.getParent();
          parentView.removeView(view);

To do this, rename arg0 to view, and you should be fine

Another option, as you mention is to just toggle its visibility, calling the setVisibility method, to either View.GONE or View.INVISIBLE depending on wether you want to to keep taking the screen space it was taking when visible or be completely gone, but since you asked to remove the view, the first option should suffice.
