Answer 1

First, you need to update the dependency

compile ‘com.android.support:design:25.0.0’

Design for bottom navigation https://xmleditoronline.org/?id=ac92e01a0aa54dbd376795b4742a41ba-S2nSrO

And here is how you should format the items under them https://xmleditoronline.org/?id=ac92e01a0aa54dbd376795b4742a41ba-1dKLUF

BottomNavigationView bottomNavigationView = (BottomNavigationView)
                findViewById(R.id.bottom_navigation);

bottomNavigationView.setOnNavigationItemSelectedListener(
        new BottomNavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.action_favorites:

                        break;
                    case R.id.action_schedules:

                        break;
                    case R.id.action_music:

                        break;
                }
                return false;
            }
});
