景观模式

肖像模式

这是我的menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item  
     android:id="@+id/menu_item_search"
     android:title="Search"
     android:showAsAction="ifRoom"
     android:icon="@android:drawable/ic_menu_search" 
     android:actionViewClass="android.widget.SearchView" />
<item 
     android:id="@+id/submit"
     android:title="submit"
     android:showAsAction="always" /> 
</menu>

这是我的主要活动

请帮我。

Answer 1

如果您不关心SearchView在开始时是否已折叠，请尝试像这样配置SearchView：

 android:showAsAction="collapseActionView|ifRoom"

这应该使动作栏显示，SearchView和你的按钮。 此外，SearchView只会在展开时占用剩余的空间。

Answer 2

根据developer.android.com

如果您的应用程序使用支持库以获得与Android 2.1一样低的版本的兼容性，那么android：namespace中不提供showAsAction属性 。 相反，此属性由支持库提供，您必须定义自己的XML命名空间并将该命名空间用作属性前缀。 （自定义XML命名空间应该基于您的应用程序名称，但它可以是您想要的任何名称，并且只能在您声明它的文件范围内访问。）例如：

res / menu / main_activity_actions.xml >>>>

   <menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <!-- Search, should appear as action button -->
    <item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          yourapp:showAsAction="ifRoom"  />
    ...
 </menu>

Answer 3

SearchView将默认占用纵向模式中的大多数（如果不是全部）操作栏。 尝试在menu.xml中减小SearchView的大小，看看是否显示了该按钮。
