我目前正在尝试将DSLV库实现到我的ListFragment类中，我收到了错误

根据错误，第43行似乎会导致java.lang.NoClassDefFoundError：。看起来DropListener的声明导致了这个问题。它也可能是由我在xml文件中做出的声明引起的吗？这是源代码：
public class FavoritesTab extends ListFragment
{
private JazzAdapter adapter;
private ArrayList<JazzArtist> mArtists;
private String[] mArtistNames = {"Brighouse Stn Bay 7", "Nb No.3 Rd Fs Francis Rd", "Sb Westbrook Mall Fs University--"};
private String[] mArtistAlbums = {"402: 1:40pm, 2:10pm\n403: 1:39pm, 2:01pm, 2:22pm\n404: 1:46pm, 2:16pm\n410: 1:39pm, 1:50pm, 2:09pm, 2:19pm, 2:23pm\n",
"403: 1:53pm, 2:13pm, 2:33pm\n",
"025: 1:38pm, 1:50pm, 2:02pm, 2:14pm, 2:26pm\n033: 2:01pm, 2:31pm\n041: 1:45pm, 2:08pm, 2:25pm\n"};
private String[] mStops = {"56549", "56616", "61598"};
private DragSortListView.DropListener onDrop =
new DragSortListView.DropListener() {
@Override
public void drop(int from, int to) {
JazzArtist item = adapter.getItem(from);
adapter.remove(item);
adapter.insert(item, to);
}
};
private DragSortListView.RemoveListener onRemove =
new DragSortListView.RemoveListener() {
@Override
public void remove(int which) {
adapter.remove(adapter.getItem(which));
}
};
/** Called when the activity is first created. */
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
MainActivity ma = (MainActivity) getActivity();
DragSortListView lv = (DragSortListView) getListView();
lv.setDropListener(onDrop);
lv.setRemoveListener(onRemove);
mArtists = new ArrayList<JazzArtist>();
for(int i=0; i<3; i++) {
JazzArtist ja = new JazzArtist();
ja.name = mArtistNames[i];
ja.albums = mArtistAlbums[i];
ja.stop_no = mStops[i];
mArtists.add(ja);
}
adapter = new JazzAdapter(mArtists);
setListAdapter(adapter);
//ma.refreshList();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.activity_favorites_tab, container, false);
return view;
}
private class JazzArtist {
public String name;
public String albums;
public String stop_no;
@Override
public String toString() {
return name;
}
}
private class ViewHolder {
public TextView albumsView;
public TextView stopNo;
}
private class JazzAdapter extends ArrayAdapter<JazzArtist> {
public JazzAdapter(List<JazzArtist> artists) {
super(getActivity(), R.layout.jazz_artist_list_item,
R.id.artist_name_textview, artists);
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
if (v != convertView && v != null) {
ViewHolder holder = new ViewHolder();
TextView tv = (TextView) v.findViewById(R.id.artist_albums_textview);
TextView tv2 = (TextView) v.findViewById(R.id.stop_number_textview);
holder.albumsView = tv;
holder.stopNo = tv2;
v.setTag(holder);
}
ViewHolder holder = (ViewHolder) v.getTag();
String albums = getItem(position).albums;
String stop_no = "Bus Stop " + getItem(position).stop_no;
holder.albumsView.setText(albums);

编辑 - 事实证明，我没有正确导入库。但是，我现在面临一个新问题。我收到了错误

这是我的XML布局：

如果我将“xmlns：android =”http://schemas.android.com/apk/res/android“”更改为“xmlns：dslv =”http://schemas.android.com/apk/ RES / com.mobeta.android.demodslv” “，我会得到一个”No resource ifentifier found“错误。
答案 0 :(得分：1)
您的网址可能错误。它应该是：http://schemas.android.com/apk/lib/com.mobeta.android.dslv 您正在使用“com.mobeta.android.demodslv”
进入演示项目答案 1 :(得分：0)
似乎您的DragSortListView未添加为项目中的库。并不总是需要在项目库中包含jar。有时整个项目可以用作库。 通过检查属性 - ＆gt; Android下的Android。来检查演示是否包含DSLV项目。
答案 2 :(得分：0)
你使用的是哪个版本的android？ ListFragment可以在版本11中使用。您必须添加'support.v4.jar'。
