Question

我想根据点击的项目替换包含项目列表的片段和新片段。这是我的代码，我该如何处理？我应该在onCreateView或onActivityCreated中声明我的ListView，Adapter等吗？如果容器有所不同，那么容器就是ViewPager。

public class PreferenceListFragment extends SherlockFragment 
{
    ListView lv;

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState)  {
        return (LinearLayout)inflater.inflate(R.layout.settings, container, false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        lv = (ListView)getView().findViewById(R.id.SettingsLV);
        lv.setAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, Preferences.TITLES));
        lv.setOnItemClickListener(new OnItemClickListener()
            {
                @Override
                public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                    Log.i("FragmentList", "Item clicked: " + arg2);
                    // Switch case that starts fragment depending on 'position'.

                    Fragment1 f1 = new Fragment1();
                    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
                    ft.replace(R.id.pager, f1);
                    ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
                    ft.addToBackStack(null);
                    ft.commit();     
                }
            }
        );
    }
}

适配器和列表视图的设置应该在onActivityCreated中完成。 OnCreateView只是第一次绘制用户界面。处理应该在onActivityCreated（）中。请参阅http://developer.android.com/guide/topics/fundamentals/fragments.html

使用ViewPager作为容器替换片段onItemClick
