我有一个片段,我试图添加到视图中.

FragmentManager fragMgr=getSupportFragmentManager();
feed_parser_activity content = (feed_parser_activity)fragMgr
                                    .findFragmentById(R.id.feedContentContainer);
FragmentTransaction xaction=fragMgr.beginTransaction();

if (content == null || content.isRemoving()) {
    content=new feed_parser_activity(item.getLink().toString());
    xaction
        .add(R.id.feedContentContainer, content)
        .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
        .addToBackStack(null)
        .commit();
    Log.e("Abstract", "DONE");
}

执行此代码时,我在调试中收到以下错误.

java.lang.IllegalArgumentException: No view found for id 0x7f080011 
   for fragment feed_parser_activity{41882f50 #2 id=0x7f080011}

feed_parser_activity是一个片段,在xml中设置为Fragment layout.
我正在使用FragmentActivity来托管片段布局feed_parser_layout.
我上面正确编码吗？

MyFragment.java

public class MyFragment extends Fragment {
    private onItemSelectedListener listener;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment, container,
                false);
        btn_myButton = (Button) view.findViewById(R.id.btn_new_client);
        btn_myButton .setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                updateDetail("New Layout");
            }
        });
        return view;
    }

    Button btn_myButton;

    public interface onItemSelectedListener {
        public void onItemSelected(String link);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        if (activity instanceof onItemSelectedListener) {
            listener = (onItemSelectedListener) activity;
        } else {
            throw new ClassCastException(activity.toString()
                    + …

我有一个非常奇怪的问题.我有一个常见的片段,几乎在我的应用程序的每个活动中都添加了.此片段显示了一个小版本的播放器栏.所以它会收听一些广播以更新当前音乐的名称,并有一些控制,如播放/暂停.

就像我说的,我几乎在我的应用程序的每个活动中都添加了这个片段,我从来没有遇到任何问题.但现在,我需要创建一个没有UI且保留的新片段(setRetainInstance(true)).添加这个新片段后,一切似乎都没问题.直到我旋转设备并且活动崩溃.

所以,查看日志,我看到以下异常:
