android - menu.xml 中的 ActionbarSherlock SearchView 给出 Resources$NotFoundException

Question

当我尝试将 ActionbarSherlock SearchView 添加到我的 ActionBar 时，应用程序在应显示 Activity 时立即崩溃。为此，我在 LogCat 中发现了以下内容:

10-22 21:22:51.070: W/MenuInflater(21873): Cannot instantiate class: com.actionbarsherlock.widget.SearchView

当我将常规 android.widget.SearchView 用于 android:actionViewClass 时，一切正常。我关注了tutorial来自 Android 网站。

这是我的菜单xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/menu_search"
        android:actionViewClass="com.actionbarsherlock.widget.SearchView"
        android:icon="@drawable/ic_action_search"
        android:showAsAction="ifRoom|collapseActionView"
        android:title="@string/menu_search"/>

    <item android:id="@+id/menu_add_page"
        android:title="@string/menu_add_page"
        android:icon="@drawable/ic_action_add"
        android:showAsAction="always" />

    <item android:id="@+id/menu_settings"
        android:title="@string/menu_settings"
        android:showAsAction="never" />
</menu>

这是相关代码:

public boolean onCreateOptionsMenu(Menu menu) {
    getSupportMenuInflater().inflate(R.menu.activity_overview, menu);

    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

    return true;
}

这是一个(已知的)错误，还是我在这里遗漏了什么？

此问题是由于 v-14 版本的 Sherlock 主题缺少某些属性导致的。

我通过添加修复了它

<item name="textColorPrimary">@color/abs__primary_text_holo_light</item>
<item name="textColorPrimaryInverse">@color/abs__primary_text_holo_dark</item>

到 Sherlock 主题，它再次运行得很漂亮。不确定是否是理想的解决方案，但目前它有效:)
