Answer 1

This worked for me...

OneFragmen.java

public class OneFragment extends Fragment{

public OneFragment() {
    // Required empty public constructor
}
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;

int progress=0;
private Handler handler = new Handler();
TextView txtProgress;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(
    LayoutInflater inflater, 
    ViewGroup container,
    Bundle savedInstanceState ) {

   View view =  inflater.inflate(R.layout.fragment_one, container, false);
    getActivity().setTitle(R.string.app_name);

   final ProgressBar spinner = 
       (ProgressBar) view.findViewById(R.id.outerProgressBar);
    Resources res = getResources();
    Drawable drawable = res.getDrawable(R.drawable.circular);
    txtProgress = (TextView)view.findViewById(R.id.txtProgress);
    spinner.setProgressDrawable(drawable);
    spinner.setSecondaryProgress(100);
    spinner.setMax(100);
    spinner.setProgress(0);

    new Thread(new Runnable() {

        @Override
        public void run() {
            while (progress < 100) {
                progress += 1;
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        spinner.setProgress(progress);
                        txtProgress.setText(progress + "%");
                    }
                });
                try {
                    Thread.sleep(28);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }).start();
    return view;
  }
}
