java.lang.IllegalArgumentException:找不到片段片段的 id (someid) (id/

Question

在我的应用程序中，我有一些片段。从我使用以下代码的活动中，我将Fragment加载到片段组中以供Fragment

FragmentManager fm;
FragmentTransaction ft = fm.beginTransaction();
f3 = new CustomerTransactionFragment();
ft.add(R.id.fragmentgroup,f3,"C");
ft.commit();

在CustomerTransactionFragment() ;

public class CustomerTransactionFragment extends SherlockFragment
{
      @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.customertransaction, container, false);
            return view;
        }
      @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
         Fragment fragment = null;
           fragment = new CustomerSearchFragment();
           if (fragment != null) {
               FragmentManager fragmentManager = getChildFragmentManager();
                fragmentManager.beginTransaction()
                        .replace(R.id.customertransaction_form_fragmentgroup, 
                                fragment).commit();
           }
    }
}

这里customertransaction _form_fragmentgroup LinearLayout customertransaction.xml用于加载子Fragment，如CustomerSearchFragment。

由于长度 从CustomerSearchFragment我只表示下面的基本代码，

    ListView lv;
    ListAdapter adapter;
@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.customerlist, container, false);
@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);
        lv = (ListView) view
                .findViewById(R.id.ccustomerlist_form_ListViewcustomers);
        adapter = new SimpleAdapter(getActivity(), dataList,
                R.layout.singlecustomerselect, new String[] { TAG_NAME, TAG_ID,
                        TAG_PHONE }, new int[] { R.id.sincusname,
                        R.id.sincusid, R.id.sincusgsm });
    lv.setAdapter(adapter);

我没有包含用于设置适配器的代码，因为加载适配器没有问题。它完美地显示项目，并且在项目单击时也会选择当前项目。当我尝试在customertransaction_form_fragmentgroup中用新Fragment替换当前时，当执行项目单击时，出现问题。

lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // getting values from selected ListItem
                Toast.makeText(
                        getActivity(),
                        "NAME:" + selname + "nCODE:" + selcode
                                + "nPHONE:" + selphno, Toast.LENGTH_LONG)
                        .show();
                  Fragment fragment = null;
                  fragment = new CustomerDetailDisplayFragment();
                   if (fragment != null) {
                       FragmentManager fragmentManager = getChildFragmentManager();
                        fragmentManager.beginTransaction()
                                .replace(R.id.customertransaction_form_fragmentgroup, fragment).commit();
                   } 

            }
        });
}

日志猫如下

请帮助找到解决方案。提前感谢..

确保CustomerDetailDisplayFragment是否有View .例如，是否为该Fragment分配布局 ( CustomerDetailDisplayFragment (。如果在 next 中未创建View Fragment将引发异常。
