You need to implement an AsyncTask.
Example:

class YourAsyncTask extends AsyncTask<Void, Void, Void> {

    private ProgressDialog progressDialog;

    @Override
    protected void onPreExecute() {
        //show your dialog here
        progressDialog = ProgressDialog.show(this, "title", "message", true, false)
    }

    @Override
    protected Void doInBackground(Void... params) {        
        //make your request here - it will run in a different thread
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        //hide your dialog here
        progressDialog.dismiss();
    }
}

Then you just have to call

new YourAsyncTask().execute();
