How do I show and then remove an android progress dialog

Question

I can get a progress bar to appear with the following code

Answer 1

To remove a progressBar

ProgressBar progressbar = (ProgressBar)findViewById(R.id.progressbarID);

progressBar.setVisibility(View.INVISIBLE) ;

hide the progressbar in xml and show it like

 ProgressBar progressbar = (ProgressBar)findViewById(R.id.progressbarID);

    progressBar.setVisibility(View.VISIBLE) ;
