为什么Android SearchWidget不发送意图？

好的，我已经阅读了这个网站上的所有教程和内容，这应该是有效的。我在以前的一个项目中尝试过这样做，得到了同样的结果，所以我错过了比打字更高级的东西

搜索窗口小部件出现并似乎正在工作。但是，当提交搜索时，不会发生任何事情。它就在那里。我尝试重写onNewIntent（）和onSearchRequested（）以添加Log.d（）输出，以查看是否调用过该代码。我也在那里添加了断点。。。没有什么！这似乎说明了清单中的意图是如何建立的，但在我看来是正确的。也许另一双眼睛可以发现一些东西

manifest.xml代码段

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:launchMode="singleTop"
    android:theme="@style/AppTheme" >
    <meta-data android:name="android.app.default_searchable"
        android:value=".DeckView" />
    <activity
        android:name=".DeckView"
        android:label="@string/title_activity_deck_view" >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:value="@xml/searchable" />
    </activity>

    <activity

任何帮助或见解都将不胜感激。我想我从来没有像现在这样撞到过砖墙，我甚至不知道如何调试它

您的DeckView活动是否扩展了

ActionBarActivity

？您是否有一个用于搜索和搜索reslut的活动？@adavis。不，它只是延伸Activity@Aryan-有点。.DeckView活动在SQL数据库中放置一个表示虚拟组（dbh.createSearchDeck）的条目，并加载另一个显示结果的活动（.ShowCard）。这可以绕过小部件正常工作。从未调用该代码。好的，您可能需要扩展

ActionBarActivity
