//1 获取ActionBar对象并设置属性

//        actionBar.setIcon(R.mipmap.ic_launcher);//图标
actionBar.setTitle(getString(R.string.app_name));// 设置标题

//给drawerlayout添加监听
//方法一：
drawerLayout.setDrawerListener(toggle);
//方法二：
//        drawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
//            @Override
