搜索视图不在操作栏内。在onCreate上我写道：

// Searchview
    mSearchView = (SearchView) findViewById(R.id.search_view); 

    lvItem.setAdapter(new ArrayAdapter<String>(this,
             R.layout.customlistview,
             mStrings));
    lvItem.setTextFilterEnabled(true);
     setupSearchView();

   ////

其中mStrings为private final ArrayList<String> mStrings = MainActivity.itemArrey;，而itemArrey是listview中的数据。为什么会崩溃？

编辑：导入是：import com.actionbarsherlock.widget.SearchView;所以很奇怪

直接使用findViewById无法找到菜单项

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.your_menu_xml, menu);

    searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) searchItem.getActionView();
    //do your stuffs
    return super.onCreateOptionsMenu(menu);
}

如果您要定位较低版本，请使用

SearchView searchView =(SearchView) MenuItemCompat.getActionView(searchItem);

Actionbarsherlock和searchview不起作用。应用程序崩溃
