我已经被这个问题难住了几天了，我正在掉头发。我在网上翻了几页又一页的问题，还没有找到答案，所以希望能得到一些帮助！我有一个带有导航抽屉的主要活动的 Android 4.0 应用程序 - 它工作正常。根据选择的菜单项，我加载一个 Fragment 或 ListFragment。这再次工作正常。

现在，我正在尝试使用 ActionbarSherlock 为 Gingerbread 提供支持。我更新了我的主要活动和代码以使用 ABS 库，但我现在只在我的 2.3 版模拟器上遇到错误！更新后的代码在 4.0+ 上仍然可以正常工作！

我收到以下错误：Binary XML file line #18: Error inflating class on my activity_main.xml

也许我已经盯着这个太久了，但我不明白为什么它适用于 ICS 及更高版本，但不适用于 Gingerbread！有谁知道我在这里想念什么？

这是我的代码：

活动主.xml：

<?xml version="1.0" encoding="utf-8"?>
<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" >

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="280dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:background="@color/list_background"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_selector" />

</android.support.v4.widget.DrawerLayout>

strings.xml 片段：

<!-- Nav Drawer Menu Items -->
<string-array name="nav_drawer_items">
    <item>Frag 1</item>
    <item>Frag 2</item>
    <item>Frag 3</item>
    <item>Frag 4</item>
</string-array>

<!-- Nav Drawer List Item Icons -->
<!-- Keep them in order as the titles are in -->
<array name="nav_drawer_icons">

    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        // Pass any configuration change to the drawer toggls
        mDrawerToggle.onConfigurationChanged(newConfig);
    }
}

我还更新了清单以使用 android:minSdkVersion="8" 和 android:theme="@style/Theme.Sherlock.Light.DarkActionBar"

我还不能发表评论，但我注意到你正在使用invalidateOptionsMenu()而不是supportInvalidateOptionsMenu(). 我不确定这是否能解决您的问题，但这看起来确实是错误的。
