You should use AsyncTask instead actually.

Here is the link to the library. It is fairly simple:

1) onPreExecute() = show ProgressDialog

2) doInBackground() = execute your code

3) onPostExecute() = dismiss ProgressDialog

Here's a nice tutorial too.

In general:

@Override
protected void onPreExecute() {
    dialog = new ProgressDialog(this.context);
    dialog.setMessage("Loading...");
    dialog.setCanceledOnTouchOutside(false);
}

@Override
protected void onPostExecute(String result) {
    if(dialog.isShowing()) {
        dialog.dismiss();
    }
}
