What is best way to remove ProgressDialog

Question

I have created a progress dialog by

ProgressDialog progressDialog = null; // create instance variable of ProgressDialog
int dialogID = 1;
//to create progress dialog

protected Dialog onCreateDialog(int id) {
progressDialog = new ProgressDialog(context);
progressDialog.setMessage(message);
progressDialog.setIcon(android.R.id.icon);
return progressDialog;
}

// to show progressdialog 
showDialog(dialogID);

To remove the dialog I am able to use any of the following three approaches

approach-1

if(progressDialog != null){
progressDialog.dismiss();
}

approach-2

if(progressDialog != null){
    progressDialog.cancel();
    }

approach-3

removeDialog(dialogID);

I found second approach is more effective than first approach. and if I have to use with more than one progressdialog it is easier to use approach-3. But what is the best way to destroy a progressdialog and How?

Answer 1

cancel(); is better than dismiss() because according to docs:

Cancel the dialog. This is essentially the same as calling dismiss(), but it will also call your DialogInterface.OnCancelListener (if registered).

removeDialog() is deprecated so that would be the worst way.

Answer 2

I think below way is the best to dismiss the progress bar from screen:

if(progressDialog.isShowing())
{
   progressDialog.dismiss();
}
