好的，这是我的问题：
我想用片段实现 Chrisbanes ActionBar-PullToRefresh 库，以便能够将它与 Navigationdrawer 一起使用。
https://github.com/chrisbanes/ActionBar-PullToRefresh#fragments
.
Chrisbanes 说这是为了与片段一起使用：
需要注意的一点是，PullToRefreshAttacher 需要在 Activity 的 onCreate() 阶段创建。如果您打算将此库与 Fragments 一起使用，那么最佳实践是让您的 Activity 创建 PullToRefreshAttacher，然后让您的 Fragment 从 Activity 中检索它。
Fragment & Tabs 示例中提供了一个示例。
.
.
****问题来了：我在我的活动中创建了 PullToRefreshAttacher，但是我怎么能将 PullToRefreshAttacher 传递给我的片段：S****
我已经阅读了很多关于 bundles 和 getArguments() 与 putSerializable 和 Parcelable ：
而且我也读到了这篇文章里面的…… 像这样((MyActivity ) getActivity()).getClassX() ;使用。
但我没有真正理解/工作。:(

这是 NavigationActivity 和一个示例片段。我不得不说我是 android/Java 的新手 :)
final String[] menuEntries = {"Start","Datum","Website","Kunden"};

};
private ActionBarDrawerToggle drawerToggle;
private DrawerLayout drawerAdapter;

private PullToRefreshAttacher mPullToRefreshAttacher;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_layout);
mPullToRefreshAttacher = PullToRefreshAttacher.get(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActionBar().getThemedContext(), android.R.layout.simple_list_item_1, menuEntries);
final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.refresh_navwiev);

navList.setAdapter(adapter);
navList.setOnItemClickListener(new OnItemClickListener(){

}
return super.onOptionsItemSelected(item);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
还有一个片段
public class MainFragment extends Fragment {
public static Fragment newInstance(Context context) {
MainFragment f = new MainFragment();
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
如果有人可以帮助我，那就太好了，我在这一点上被困了好几天:)
