Cast исключение с андроида ящиками

Question

Ave,

я учусь Android выдвижных ящиков: «http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/» и я столкнулся странные проблемы. При запуске приложения он бросает:

Answer 1

Я думаю, что ваш mDrawerList должен быть непосредственно в DrawerLayout, и именно поэтому он говорит вам, что параметры макета не могут быть отлиты. Ваш XML должен выглядеть в примере вы публикуемую, что вы используете так что-то вроде этого:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/drawer_layout" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

    <android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/pager" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@drawable/bg1" 
     tools:context="com.lanceit.haito.lanceit.activities.HubActivity"> 

    <android.support.v4.view.PagerTitleStrip 
     android:id="@+id/pager_strip" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:background="@color/primary_material_dark" 
     android:paddingBottom="10dp" 
     android:paddingTop="10dp" /> 
    </android.support.v4.view.ViewPager> 
    <CheckedTextView 
     android:id="@+id/home_drawer_cv_banks" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" 
     android:background="@android:color/holo_red_light" 
     android:focusable="true" 
     android:text="Some Dummy Text" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     android:textColor="#FFF" /> 
    <ListView 
     android:id="@+id/list_slidermenu" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:background="@android:color/holo_red_light" 
     android:choiceMode="singleChoice" 
     android:divider="@android:color/black" 
     android:dividerHeight="5dp" > 
    </ListView> 

Взгляните еще раз на примере вы дали http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

P.S. Другой способ, не изменяя ваш xml, - передать метод isDrawerOpen LinearLayout, в котором находится ListView, но который находится непосредственно в вашем DrawerLayout, так что это тот, который имеет RelativeLayout в нем. См. Этот вопрос What do you need to pass to v4.widget.DrawerLayout.isDrawerOpen()/.openDrawer()/.closeDrawer()
