無法實例類：com.actionbarsherlock.widget.SearchView

這是我menu.xml文件無法實例類：com.actionbarsherlock.widget.SearchView

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

    <item 
     android:id="@+id/menu_search" 
     android:actionViewClass="com.actionbarsherlock.widget.SearchView" 
     android:showAsAction="always|withText" 
     android:title="Search"/> 

</menu>

我試圖誇大這一menu.xml在

MainActivity.java

@Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     super.onCreateOptionsMenu(menu); 
     MenuInflater inflater=new MenuInflater(getBaseContext()); 
     inflater.inflate(R.menu.menu, menu); 

     return true; 
    }

但logcat拋出錯誤

我也保留主題爲android:theme="@style/Theme.Sherlock.Light"

我該如何解決這個錯誤？

添加代碼的評論部分解決了問題不完全，但它很好。

@Override 
     public boolean onCreateOptionsMenu(Menu menu) { 
      super.onCreateOptionsMenu(menu); 
      MenuInflater inflater=new MenuInflater(getBaseContext()); 
      inflater.inflate(R.menu.menu, menu); 
      // adding this section of code resolved the problem 
      SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
      com.actionbarsherlock.widget.SearchView searchView = new com.actionbarsherlock.widget.SearchView(getSupportActionBar().getThemedContext()); 
      searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 
      menu.findItem(R.id.menu_search).setActionView(searchView); 
      return true; 
     }

但它顯示在logcat中相同的警告，因爲我張貼在的問題，我發現這是/是衆所周知的問題ActionBarSherlock更多細節click here
