How to close SearchView in android with ActionbarSherlock or android ActionBar

When I use a search view for search something in android action bar;

u must have create a menu for actionview( SearchView)

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.news_post_list, menu);
    mSearchView = (SearchView) menu.findItem(R.id.item_search).getActionView();
    mSearchView.setQueryHint(getString(R.string.search_hint_news));
    mSearchView.setOnQueryTextListener(this);
    super.onCreateOptionsMenu(menu, inflater);
}

and menu xml is :

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item 
    android:id="@+id/item_search"
    android:icon="@drawable/ic_action_search"
    android:title="@string/search_hint"
    android:showAsAction="ifRoom"
    android:actionViewClass="com.actionbarsherlock.widget.SearchView"/>
<item
    android:id="@+id/item_tweet_add"
    android:icon="@drawable/contribute"
    android:showAsAction="always"
    android:title="@string/tweet_new"
    android:titleCondensed="@string/tweet_new"/>
</menu>

I input my keywords for search if click search then activity go search like exm:

@Override
public boolean onQueryTextSubmit(String query) {
    Intent intent = new Intent(mContext, NewsSearchActivity.class);
    intent.putExtra("query", query);
    startActivity(intent);
    return true;
}

A new activity start for show you search result. Now I finish this activity or fragment. The search view is open and wait me input (I want it's close).

so you can do like this :

mSearchView.onActionViewCollapsed();
mSearchView.setQuery("", false);
mSearchView.clearFocus();
