Answer 1

try this use setSelectedItemId() method of your BottomNavigationView like this

BottomNavigationView bottomNavigationView;
bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottomNavigationView);
bottomNavigationView.setSelectedItemId(R.id.home_menu);

or use viewPager.setCurrentItem(); of your view pager like this

viewPager.setCurrentItem(2);

Answer 2

   /***Just try to use below code snipet***/

   viewPager.setCurrentItem(2);

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
   {
     home_icon.setImageDrawable(getResources().getDrawable(R.drawable.home_icon_selected_state, getApplicationContext().getTheme()));

   }
   else
   {
     home_icon.setImageDrawable(getResources().getDrawable(R.drawable.home_icon_selected_state));
   }
