cwac Touch ListView重复项目

Question

我在定制cwac touchlistview时遇到问题。我的代码几乎与示例相同。唯一的区别是我使用自定义arraylist而不是字符串列表。

我注意到几个问题：

• 如果我点击图标（抓取器），它会将消息复制到上一个。如果我有四个项目的列表，我点击最后一个三次，那么我有相同的消息列表。
• 如果我将行移到屏幕顶部（有其他图标 - 见图），它将消失。

任何想法我应该改变什么？

import com.commonsware.cwac.tlv.TouchListView;

public class Reorder extends ListActivity{

    ArrayList<Message> list = new ArrayList<Message>();

    private CustomAdapter myAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.maincommit);

        prekopiraj();

        TouchListView tlv=(TouchListView)getListView();
        myAdapter = new CustomAdapter();
        setListAdapter(myAdapter);

        tlv.setDropListener(onDrop);
        tlv.setRemoveListener(onRemove);
    }

    private void prekopiraj(){
        for(int i = 0; i<WaitingRoom.messagescopy.size(); i++){
            list.add(WaitingRoom.messagescopy.get(i));
        }
    }

    private TouchListView.DropListener onDrop=new TouchListView.DropListener() {
        @Override
        public void drop(int from, int to) {
                Message item=myAdapter.getItem(from);

                myAdapter.remove(item);
                myAdapter.insert(item, to);
        }
    };

    private TouchListView.RemoveListener onRemove=new TouchListView.RemoveListener() {
        @Override
        public void remove(int which) {
            myAdapter.remove(myAdapter.getItem(which));
        }
    };

    private class CustomAdapter extends ArrayAdapter<Message>{
        CustomAdapter() {
            super(Reorder.this, R.layout.rowcommit, list);
        }

            View v = convertView;

            if (v == null) {
                LayoutInflater inflater=getLayoutInflater();

                v=inflater.inflate(R.layout.rowcommit, parent, false);
            }
            Message o;
            o = list.get(position);

            if (o != null) {
                    TextView tt = (TextView) v.findViewById(R.id.textView111);
                    TextView bt = (TextView) v.findViewById(R.id.textView112);
                    TextView te = (TextView) v.findViewById(R.id.textView113);

                    ImageView iv = (ImageView) v.findViewById(R.id.imageView4);

                    if (tt != null) {
                          tt.setText("ID: " +Integer.toString(o.getorder_id()) + " Ura: " + o.gettime());
                    }
                    if(bt != null){
                          bt.setText(o.getcustomer_address());
                    }
                    if(te != null) {
                        te.setText(o.getphone());
                    }
                    if(rt != null){
                        rt.setText(o.getfood_order());
                    }
            }

            return(v);
        }
    }
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
     // TODO Auto-generated method stub
     super.onListItemClick(l, v, position, id);
     String selection = l.getItemAtPosition(position).toString();
     Toast.makeText(this, selection, Toast.LENGTH_LONG).show();
    }
}
