空指针异常在夏洛克操作栏与选项菜单

Question

我想夏洛克操作栏默认夏洛克搜索小部件。搜索图标显示在夏洛克操作栏上，但点击它的强制关闭。我的日志如下所示

  @Override
public boolean onCreateOptionsMenu(Menu menu) 
{
    MenuInflater inflater = getSupportMenuInflater();
            inflater.inflate(R.menu.tvguide_menu, menu);
     }
  public boolean onOptionsItemSelected(MenuItem item)

      Log.e("", "itemselected" +item.getItemId());
       switch(item.getItemId())

                Toast.makeText(TVBuddyMainActivity.this,"search selected", Toast.LENGTH_LONG).show();
                Intent intent = new Intent(TVBuddyMainActivity.this,CustomSearch.class);
                startActivity(intent);
                break;
        }
     return true;
}

这是ActionBarSherlock 4.3.0版本的一个bug，我用下面的方法修复了它:
