/**
 * 1.完成项目XML布局,初始化控件
 *  a.根布局不再是LinerLayout,而是DrawerLayout
 *  b.写两个直接的子控件,LinerLayout,Fragment
 *  c.TabLayout(依赖)和VIewPager
 *
 * 2.初始化ActionBar和ToolBar一样的存在
 *  a.获取一个ActionBar对象
 *  b.给ActionBar设置图片
 *  C.ActionBar关联DrawerLayout
 *  d.DrawerLayout关联ActionBar
 *
 * 3.初始化VIewPager
 *  a.创建一个装Fragment的集合
 *  b.创建Fragment,把Fragment添加到容器中
 *  c.创建VIewPager的适配器写其逻辑
 *
 * 4.是两两之间相互关联
 * a.tabLayout创建指示器
 * b.TabLayout与VIewPager相关联
 * c.给TabLayout指示器设置文本
