The ProgressBar is a UI element that indicates the progress of an operation; in this action you are doing there is no action that requires ProgressBar.

An example where you can use ProgressBar is to use AsyncTasks to load API data, image download and etc ... unless to simulate the progress you use some postDelayed by setting a time to simulate a delay in screen transition.

 btiniciar = (Button) findViewById(R.id.btiniciar);
    btiniciar.setOnClickListener(new View.OnClickListener(){
      public void onClick(View v) {

                //MOSTRAR PROGRESS
                final Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                     //ESCONDER PROGRESS
                       Intent it = new Intent(MenuActivity.this,LoadActivity.class);
                       startActivity(it);
                       finish();
                    }
                }, 2000);
      }
    });
