我正在尝试从Android http://developer.android.com/design/patterns/navigation-drawer.html#ImpactOnNav导入使用新"导航抽屉"所需的类
DrawerLayout:http: //developer.android.com/reference/android/support/v4/widget/DrawerLayout.html
ActionBarDrawerToggle:http: //developer.android.com/reference/android/support/v4/app/ActionBarDrawerToggle.html
导入android.support.v4.widget.DrawerLayout无法解析导入android.support.v4.app.ActionBarDrawerToggle无法解析
我已将库更新到最新版本,但仍然无法识别这些类.
