我有一个错误，我无法复制。我认为这是关于应用程序何时被使用然后用户切换aps并进入主屏幕一段时间然后回到我的应用程序。完整的错误是：

最后我的菜单xml如下所示：
<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>
我不能为我的生活弄清楚这个错误来自哪里。
答案 0 :(得分：2)
如果可能，我建议使用onOptionsItemSelected机制，而不是手动连接点击方法。

您可能找到了一个平台错误。如果将活动主题设置为Theme.Holo或Theme.Holo.Light，是否仍会发生？具体来说，尝试使用不基于Theme.Holo.Light.DarkActionBar的东西。
如果这样可以解决原始问题，请在http://b.android.com报告此问题。

你的方法签名错误。
这是你的
public void goToSearch(MenuItem item){
}
这应该是
public void goToSearch(View v){
}
请看 http://developer.android.com/reference/android/R.attr.html#onClick 供参考
