ClassNotFoundException和ActionbarSherlock SearchView

Question

我目前在Android應用程序中實現了ActionbarSherlock的4.2.0版本。 而我在使用SearchView小部件時遇到問題。

我目前已經實現了這樣的小部件：

import com.actionbarsherlock.app.ActionBar.Tab; 
import com.actionbarsherlock.app.SherlockFragmentActivity; 
import com.actionbarsherlock.view.Menu; 
import com.actionbarsherlock.view.MenuItem; 
import com.actionbarsherlock.widget.SearchView; 
import com.actionbarsherlock.widget.SearchView.OnQueryTextListener; 

public class MainActivity extends SherlockFragmentActivity 
{ 

    /*...*/ 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     SearchView searchView = new SearchView(getSupportActionBar().getThemedContext()); 
     searchView.setQueryHint(getResources().getString(R.string.searchHint_Label)); 
     searchView.setIconifiedByDefault(true); 
     searchView.setOnQueryTextListener(new OnQueryTextListener(){ 

      @Override 
      public boolean onQueryTextSubmit(String query) { 
       // Do stuff 
      } 

      @Override 
      public boolean onQueryTextChange(String newText) { 
       // TODO Auto-generated method stub 
       return false; 
      } 

     }); 

     menu.add("Search") 
      .setIcon(R.drawable.abs__ic_search) 
      .setActionView(searchView) 
      .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW); 

     return true; 
    } 
} 

現在，每當我開始調試應用程序我碰到下面的錯誤在搜索查看的構造函數：

01-01 11:46:40.365: E/dalvikvm(1385): Could not find class 'com.actionbarsherlock.widget.SearchView$11', referenced from method com.actionbarsherlock.widget.SearchView.<init>

    ZygoteInit$MethodAndArgsCaller.run() line: 839 
    ZygoteInit.main(String[]) line: 597 
    NativeStart.main(String[]) line: not available [native method] 

內出現此錯誤我使用應用程序支持的所有Android版本（2.2 - 4.2） 在發生此異常之後恢復調試時，應用程序運行良好，SearchView也可以正常工作，但我仍然在想爲什麼發生此異常。

請使用此方法以XML創建菜單：

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" >  
<item 
    android:id="@+id/search"  
    android:icon="@drawable/abs__ic_search"  
    android:showAsAction="add here your action" 
    android:title="@string/search"> 
</item> 
</menu> 

在活動

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getSupportMenuInflater(); 
    inflater.inflate(R.menu.menu, menu); 
    return true; 
} 



@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
    case R.id.search: 
     add code here 
     return true; 
    default: 
     return super.onOptionsItemSelected(item); 
    } 
}
