布局文件最外层使用DrawerLayout

只可以有两个子布局

NavigationView

NavigationView侧滑菜单，可以自行填充头部布局和菜单布局，还可以再添加任意布局

在需要使用的页面添加如下代码

public class HomeActivity extends BaseActivity {
    private DrawerLayout drawerLayout;
    private ViewPager viewPager;
    private BottomNavigationView bottomNavigationView;
    private NavigationView navigationView;

    private TabFragmentPagerAdapter tabFragmentPagerAdapter;
