问题描述
感谢寻找这个帖子。我试图实现一个搜索视图进入我的Android应用程序动作条（我将使用解析来存储数据）。我按照谷歌的，和其他一些教程我在网上发现，这是行不通的。每次我尝试启动应用程序在eclipse崩溃而不打开。（之前的工作不细的搜索查看）。
thanks for looking at this post. I am attempting to implement a search view into my android applications actionbar (I will be using Parse to store the data). I have followed google's, and few other tutorials i found online and it will not work. Every time i attempt to start the app in eclipse it crashes without opening.(it worked fine before without the searchview).

推荐答案
您应该使用支持搜索查看的支持版本：
You should use support SearchView's support version:
<item android:id="@+id/action_search"
android:title="@string/search_title"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView" />
