BottomNavigationBar这个控件的使用之前已经写过，这里不再赘述，详情请参考BottomNavigationBar的使用。
下面直接上代码：
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：
@Overridepublic 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);}mit();}
说明：这几篇文章没有过多的文字叙述，因为这些东西也不是很难，而且都是常用的，相信很多人都了如指掌了，多说亦是废话，直接上代码看的反而更清楚。
