初始化及相关设置：
mBottomNavigationBar = (BottomNavigationBar) view.findViewById(R.id.bottom_navigation_bar); mBottomNavigationBar.setBackgroundStyle(BottomNavigationBar.BACKGROUND_STYLE_STATIC); mBottomNavigationBar.setMode(BottomNavigationBar.MODE_FIXED); mBottomNavigationBar.addItem(new BottomNavigationItem(R.drawable.home_fill, getString(R.string.item_home)).setInactiveIconResource(R.drawable.home).setActiveColorResource(R.color.colorPrimary).setInActiveColorResource(R.color.black_1)) .addItem(new BottomNavigationItem(R.drawable.location_fill, getString(R.string.item_location)).setInactiveIconResource(R.drawable.location).setActiveColorResource(R.color.colorPrimary).setInActiveColorResource(R.color.black_1)) .addItem(new BottomNavigationItem(R.drawable.like_fill, getString(R.string.item_like)).setInactiveIconResource(R.drawable.like).setActiveColorResource(R.color.colorPrimary).setInActiveColorResource(R.color.black_1)) .addItem(new BottomNavigationItem(R.drawable.person_fill, getString(R.string.item_person)).setInactiveIconResource(R.drawable.person).setActiveColorResource(R.color.colorPrimary).setInActiveColorResource(R.color.black_1)) .setFirstSelectedPosition(0) .initialise(); mBottomNavigationBar.setTabSelectedListener(this); setDefaultFragment();
Tab的切换：
@Override public void onTabSelected(int position) { FragmentTransaction beginTransaction = getFragmentManager().beginTransaction(); switch (position) { case 0: if (mHomeFragment == null) { mHomeFragment = HomeFragment.newInstance(getString(R.string.item_home)); } beginTransaction.replace(R.id.sub_content, mHomeFragment); break; case 1: if (mLocationFragment == null) { mLocationFragment = LocationFragment.newInstance(getString(R.string.item_location)); } beginTransaction.replace(R.id.sub_content, mLocationFragment); break; case 2: if (mLikeFragment == null) { mLikeFragment = LikeFragment.newInstance(getString(R.string.item_like)); } beginTransaction.replace(R.id.sub_content, mLikeFragment); break; case 3: if (mPersonFragment == null) { mPersonFragment = PersonFragment.newInstance(getString(R.string.item_person)); } beginTransaction.replace(R.id.sub_content, mPersonFragment); } beginTransaction.commit(); }以上就是Android中怎么利用BottomNavigationBar实现底部导航栏，小编相信有部分知识点可能是我们日常工作会见到或用到的。希望你能通过这篇文章学到更多知识。更多详情敬请关注创新互联行业资讯频道。
