Android佈局-BottomNavigationView+ViewPager+Fragment

教學: https://tomoya92.github.io/2017/04/05/android-bottomnavigationview-viewpager-fragment/

自己做完: https://github.com/WingCH/BottomNavigationView_ViewPager_Fragment

注意事項：

1. 創建佈局 -> LinearLayout ConstraintLayout (用任何layout都得)
2. 自動生成既Fragment預設會有好多野，全部刪除，只要

import...
public class Home extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_home, container, false);
    }
}

1. 修改menu/navigation.xml文件 -> res/menu/bottom_nav_menu.xml
2. Error: Failed resolution of: xxxx 解決方法 (opens new window) 保持版本一致
