Question

我需要你的帮助我尝试解决这个问题，因为5天。我尝试在我的视图parger上使用自定义视图的ListFragment。但是当ListFragment的选项卡处于活动状态时，我收到错误。我说法语所以如果我有错误请。这是我的错误

08-01 22:46:13.387: E/AndroidRuntime(8452): java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

这是我的listFragment类：

public class MomentFragment extends ListFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceBundle){

        List<Integer> list = new ArrayList<Integer>();
        list.add(R.array.pref_light_color);
        CustomMomentListViewAdapter aa = new CustomMomentListViewAdapter(getActivity());

        setListAdapter(aa);
        return inflater.inflate(R.layout.fragment_core_moment, container, false);

    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState){

        super.onActivityCreated(savedInstanceState);


    }

    public static MomentFragment newInstance(){

        MomentFragment fragment = new MomentFragment();

        return fragment;

    }

}

这是我的customAdapter类

public class CustomMomentListViewAdapter extends BaseAdapter{

    private List<Integer> mModel = new ArrayList<Integer>();
    private Context mContext;

    public CustomMomentListViewAdapter(Context context){
        mContext = context;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return mModel.size();
    }

    @Override
    public Integer getItem(int position) {
        // TODO Auto-generated method stub
        return mModel.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        CustomMomentListView v = null;

        /* if view doesn't exist we create it */
        if(convertView == null){

            v = new CustomMomentListView(mContext);

        }else{
            v = (CustomMomentListView) convertView;
        }

        v.bind(getItem(position));

        return v;
    }

    public void bind(List<Integer> model){
        mModel = model;
    }

}

这是我的自定义列表视图（custom_moment_list_view.xml）

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:drawable/dialog_holo_light_frame"
    android:orientation="vertical" >
    <TextView
        android:id="@+id/moment_item_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="15dp"
        android:text="@string/moment_empty" />

  </LinearLayout>

最后在listFragment（fragment_core_moment.xml）的onCreate函数中使用的视图源

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" />

    <TextView
        android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/moment_empty" />

</RelativeLayout>

感谢您的帮助。

将此代码移至onCreteView()

的onActivityCreated()方法

List<Integer> list = new ArrayList<Integer>();
list.add(R.string.text);
CustomMomentListViewAdapter aa = new CustomMomentListViewAdapter(getActivity());
aa.bind(list);
setListAdapter(aa);

在滑动视图中无法使用自定义listView和适配器与listFragment
