Android 如何使用onclickListener调用ListFragment

我叫碎片都能用。 但我不会成为清单碎片。 为什么不能直接打电话 没什么错

这是呼叫的类型

    teamp.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
    FragmentManager AS = getFragmentManager();
    FragmentTransaction USA = AS.beginTransaction();
//planA
    ListFragment UF =(ListFragment) AS.findFragmentById(R.id.frameLayout2);
//planB    
//Fragment UF = AS.findFragmentById(R.id.frameLayout2); 
//planA and planB Two ways to type over will not work
                    if (UF == null) {
                        String title = "Fragment A";
                        templistview usermune = new templistview(title);
                        USA.add(R.id.frameLayout2, usermune);
                        USA.addToBackStack(null);
                        USA.commit();
                        }

这是代码片段控件 templistview.java

public class templistview extends ListFragment  {
    String title1;
    TextView textView;
      private ListView listView;
        private View v;

    public templistview() {

    }

    public templistview(String title) {
        this.title1 = title;

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        View view = inflater.inflate(R.layout.templist, container, false);
        listView = (ListView)view.findViewById(R.id.listView);
        String[] arr = new String[]{
             "A","B","C","D","E","F","G"
        };
        ArrayAdapter<String> adapter = 
            new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1,arr);
        listView.setAdapter(adapter);
        return view;

    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }

    @Override
    public void onStart() {
        super.onStart();

    }

    @Override
    public void onResume() {
        super.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();


    }

    @Override
    public void onStop() {
        super.onStop();
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public void onDetach() {
        super.onDetach();
    }

    public static Fragment findFragmentById(int framelayout) {
        // TODO Auto-generated method stub
        return null;
    }

}

用户界面代码 templast.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <ListView  
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:id="@+id/listView"
    />
</LinearLayout>

---

将xml中的listview更改为

<ListView  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:id="@android:id/list" // == here is the change
/>
