Android 类型NavigationDrawerFragment的方法addView（View，int）未定义
我在应用程序中使用的是Android 类型NavigationDrawerFragment的方法addView（View，int）未定义,android,android-actionbar,navigation-drawer,Android,Android Actionbar,Navigation Drawer,我在应用程序中使用的是导航抽屉和操作栏。我想在应用程序的所有活动中几乎都使用这两种方法。我已经在我的MainActivity中声明了这两个属性，其他活动也从这个MainActivity扩展而来。现在动作栏是可见的抽屉图标也可见，但在上单击抽屉图标的，抽屉不会打开。这是我的主要活动 package com.example.nav3; import android.app.Activity; import android.content.Intent; import
