"错误"很奇怪其他时候我已经完成了它并且从未解决过这个问题......

如果我在菜单上放置"appname:actionViewClass ="android.support.v7.widget.SearchView",我的searchview不会调用onOptionsItemSelected.

表现

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />
 <activity
            android:name=".DashBoardActivity"
            android:label="">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

dash_board.xml(菜单)(如果我撤回actionViewClass他调用(onOptionsItemSelected),但如果我把他不打电话)

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

          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          appname:showAsAction="always"
          appname:actionViewClass="android.support.v7.widget.SearchView"/>

             <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_settings"
