BottomNavigationBar這個控件的使用之前已經寫過，這里不再贅述，詳情請參考BottomNavigationBar的使用。 

下面直接上代碼：

初始化及相關設置：

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的切換：

@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(); 
 
    }  

說明：這幾篇文章沒有過多的文字敘述，因為這些東西也不是很難，而且都是常用的，相信很多人都了如指掌了，多說亦是廢話，直接上代碼看的反而更清楚。
