最佳答案
GetSupportFragmentManager()和 getChildFragmentManager()之间有什么区别？
我的类继承了 Fragment，这就是为什么它不能使用 getSupportFragmentManager ()的原因。 我正在使用 getChildFragmentManager，它正在向我显示 Error-IllegalArguementException: 没有找到 id... Error 的视图。
如有任何指导，我将不胜感激。
调用 AttachmentsListFragment 的代码是
Bundle b = new Bundle();
b.putSerializable("AttachmentsList", msg.attachments);
AttachmentListFragment listfrag = new AttachmentListFragment(msg.attachments);
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.add(R.id.attachmentslistcontainer, listfrag);
transaction.addToBackStack(null);
transaction.commit();
Xml 是
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/attachmentslistcontainer"
android:orientation="vertical" >
<TextView
android:id="@+id/textViewAttachmentHeader"
style="@style/Normal.Header.Toolbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/list_separator_background"
android:ellipsize="end"
android:gravity="center"
android:maxLines="2"
android:text="@string/attachments_header"
android:textColor="#FFFFFFFF"
android:textSize="22sp"
android:textStyle="bold"
android:visibility="visible" />
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
</FrameLayout>
Java
public class AttachmentListFragment extends ListFragment implements IAttachmentsData {
ArrayList<Attachments> items = null;
Integer cellLayoutID;
Integer index;
public AttachmentListFragment() {
}
public AttachmentListFragment(ArrayList<Attachments> items) {
this.items = items;
Log.i("Logging", "Items size" + items.size()); //$NON-NLS-1$
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle bundle;
if (savedInstanceState != null) {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// TODO Auto-generated method stub
//super.onCreateView(inflater, container, savedInstanceState);
// setContentView(R.layout.attachmentslayout);
View view = inflater.inflate(R.layout.attachmentslayout, container, false);
return view;
}
@Override

super.onActivityCreated(savedInstanceState);

getActivity().getApplicationContext(),
R.layout.attachmentslistcellcontent,

}
@Override

Intent intent = new Intent();

return null;
