这就是事情......
我有一个活动，其中我已经使用标签导航实现了ActionBarSherlock，View Pager。
在Action Bar我放置了搜索视图。现在我正在使用viewPagerAdapter添加活动中的片段列表。
现在，在片段中，我放置了可扩展的列表视图，我在可扩展列表视图中显示了带有节名称的产品。
我想做什么::
我想从可扩展列表视图中搜索产品。
我遇到的问题::
我已经将searchview放在我调用不同片段的Activity中。那么如何执行搜索???
我的代码::

答案 0 :(得分：1)
我实际上是以错误的方式获取操作栏。
使用每个片段中的操作栏::
我已将setHasOptionsMenu(true);放入我的onCreate()片段
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
之后，我可以使用我放置了searchview的onCreateOptionMenu()，现在我可以从可扩展列表视图中搜索日期，从searchview获取文本。
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu, menu);
final MenuItem searchItem = menu.findItem(R.id.menu_item_search);
final SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search Here");
}
现在已经完成，问题解决了......;）
