Android底部导航栏实现（一）之BottomNavigationBar

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。

这里写图片描述

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);}beginTransaction.commit();}
