请别人帮我！我想appcompat搜索视图添加到我的项目。失败。当我android.support.v7.widget.SearchView改变搜索查看（API> 10），一切都很好。
这是我的菜单RES：
＆LT;项目机器人：ID =@ + ID / ACTION_SEARCH

@覆盖
公共无效onCreateOptionsMenu（功能菜单，MenuInflater充气）{
inflater.inflate（R.menu.teach，菜单）;
mSearchItem = menu.findItem（R.id.action_search）;
mSearchItem.setVisible（真正的）;
mSearchView =（搜索查看）MenuItemCompat.getActionView（mSearchItem）;

解决方案
问题是在恶劣的V7支持库。更新后，一切都很好。
Please somebody help me! I trying add appcompat search view to my project. Unsuccessfully. When I change android.support.v7.widget.SearchView to SearchView (API > 10) everything's fine.
This my menu res:
<item android:id="@+id/action_search"
android:title="@string/search_view_title"
android:icon="@drawable/action_search"
sabd:showAsAction="always|collapseActionView"
sabd:actionViewClass="android.support.v7.widget.SearchView" />
This how I try to use SeachView:
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.teach, menu);
mSearchItem = menu.findItem(R.id.action_search);
mSearchItem.setVisible(true);
mSearchView = (SearchView) MenuItemCompat.getActionView(mSearchItem);
mSearchView.setQueryHint(getString(R.string.search_view_hint));
mSearchView.setOnQueryTextListener(this);
}
This my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="ru.rgups.time"
android:versionCode="1"
android:versionName="1.0" >

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.Base.AppCompat.Light"
android:name="RTApplication">
