我有一個錯誤，我有麻煩重現。我認爲這是關於什麼時候應用程序正在使用，然後用戶切換APS和去主屏幕一段時間然後回到我的應用程序。完整的錯誤是：android.view.InflateException不知道爲什麼它的強制關閉

最後我的菜單XML看起來是這樣的：
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity" >
<item android:id="@+id/menu_search2"
android:actionViewClass="android.widget.SearchView"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="always|collapseActionView"
android:onClick="goToSearch" />
<item android:id="@+id/action_scan"
android:icon="@drawable/barcode"
android:onClick="scanBarcode"
android:showAsAction="ifRoom|collapseActionView"/>
</menu>
我不能爲我的數字生活從這個錯誤來自哪裏。
你瞄準什麼API？看起來像這樣：http://stackoverflow.com/questions/11245829/inflateexception-couldnt-resolve-menu-item-onclick-handler –
