android - ActionBarSherlock 和 ShareActionProvider 导致 InflateException

Question

我正在构建一个使用 ActionBarSherlock 的应用，它的 ShareActionProvider 用于为其他应用生成 Intent。我根据图书馆的 github 页面中的示例代码创建了该项目；起初，我工作得很好。然而，在那之后的一天，它就停止工作了。如果我删除有关菜单膨胀的代码， Activity 将正常加载，否则它会崩溃并出现以下异常:

如您所见，没有任何内容指向我的代码；我将问题追溯到此方法的第一行:

public class NewsDetailActivity extends SherlockFragmentActivity{
   .
   .
   .
   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
       getSupportMenuInflater().inflate(R.menu.news_detail, menu);
       //mShareActionProvider = (ShareActionProvider) menu.findItem(R.id.share).getActionProvider();
       //mShareActionProvider.setShareHistoryFileName(ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME);
       return super.onCreateOptionsMenu(menu);
   }

如果删除该行，则该 Activity 会正常运行。菜单布局如下所示:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
    android:id="@+id/share"
    android:title="@string/share"
    android:showAsAction="ifRoom"
    android:actionProviderClass="com.actionbarsherlock.widget.ShareActionProvider"/>
</menu>

我一直无法解决这个问题，也找不到有类似问题的人。但是，我确实在图书馆的 wiki 中读到主题可能是问题所在，以下是我的应用程序和操作栏的主题，我已将其更改为 Theme.Sherlock.Light 和许多其他主题但无济于事。

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="AppBaseTheme" parent="Theme.Sherlock">
    <item name="actionBarStyle">@style/ActionBar</item>
    <item name="android:actionBarStyle">@style/ActionBar</item>
</style>

<style name="ActionBar" parent="@style/Widget.Sherlock.ActionBar">
    <item name="android:textColor">#ffffff</item>
    <item name="android:textStyle">bold</item>>
    <item name="android:background">@drawable/background_actionbar</item>
    <item name="android:backgroundStacked">@drawable/background_actionbar</item>
    <item name="android:backgroundSplit">@drawable/background_actionbar</item>
</style>
</resources>

我正在使用最新版本的库。我希望有人能帮助我!谢谢!

编辑:我没能解决问题，但我在 ActionBarSherlock (layout/abs_activity_chooser_view.xml) 中追踪到这个 XML 的异常:

<com.actionbarsherlock.internal.widget.IcsLinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/abs__activity_chooser_view_content"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    style="?attr/activityChooserViewStyle">

    <FrameLayout
        android:id="@+id/abs__expand_activities_button"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:focusable="true"
        android:addStatesFromChildren="true"
        android:background="?attr/actionBarItemBackground">

        <ImageView android:id="@+id/abs__image"
            android:layout_width="56dip"
            android:layout_height="36dip"
            android:layout_gravity="center"
            android:paddingTop="2dip"
            android:paddingBottom="2dip"
            android:paddingLeft="12dip"
            android:paddingRight="12dip"
            android:scaleType="fitCenter"
            android:adjustViewBounds="true" />

    </FrameLayout>

    <FrameLayout
        android:id="@+id/abs__default_activity_button"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:focusable="true"
        android:addStatesFromChildren="true"
        android:background="?attr/actionBarItemBackground">

        <ImageView android:id="@+id/abs__image"
            android:layout_width="56dip"
            android:layout_height="36dip"
            android:layout_gravity="center"
            android:paddingTop="2dip"
            android:paddingBottom="2dip"
            android:paddingLeft="12dip"
            android:paddingRight="12dip"
            android:scaleType="fitCenter"
            android:adjustViewBounds="true" />

    </FrameLayout>

</com.actionbarsherlock.internal.widget.IcsLinearLayout>

看来异常是由FrameLayout引起的。

编辑 2: 好的，我找到了阻止应用程序崩溃的方法。我从我的应用程序中删除了自定义主题并从操作栏中删除了样式，将应用程序主题保留为:

<application android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.Sherlock" >

这很好用，但是，我失去了自定义操作栏的可能性。

Answer 1

在 AndroidManifest.xml 中将您的 Activity 样式更改为 android:theme="@style/Theme.Sherlock"

像这样

    <activity
        android:name=".MainActivity"
        android:theme="@style/Theme.Sherlock">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
