Android Iappcompat v21:材质设计操作栏（）充气异常错误充气类
正在尝试将appcompat v20中生成的应用程序移动到新库appcompat v21 使用：appcompat-v7:20工作正常 我这样做：Android Iappcompat v21:材质设计操作栏（）充气异常错误充气类,android,nullpointerexception,android-actionbar,fragment,android-appcompat,Android,Nullpointerexception,Android Actionbar,Fragment,Android Appcompat,正在尝试将appcompat v20中生成的应用程序移动到新库appcompat v21 使用：appcompat-v7:20工作正常 我这样做： ActionBarActivity implements ActionBar.TabListener, ActionBar.OnNavigationListener 并有以下几点： android.view.InflateException:二进制XML文件第17行：膨胀类android.support.v7.internal.widget.Act
ActionBarActivity implements ActionBar.TabListener, ActionBar.OnNavigationListener
