Java 安卓&x2B；ListView+；滑动元件

我正在为我的项目使用，一切正常（滑动元素），但我的问题是-是否可以通过单击某些

ListView

元素开始滑动动画

第二个问题：

如何为自定义对象实现timedSwipeUndo

这是我的

ListView的代码

final ArrayAdapter<Product> adapter = new MyListAdapter(this,R.layout.text_view,productsDef);
        SimpleSwipeUndoAdapter simpleSwipeUndoAdapter = new SimpleSwipeUndoAdapter(adapter, this, new MyOnDismissCallback(adapter));
        AlphaInAnimationAdapter animAdapter = new AlphaInAnimationAdapter(simpleSwipeUndoAdapter);
        animAdapter.setAbsListView(listView);
        assert animAdapter.getViewAnimator() != null;
        animAdapter.getViewAnimator().setInitialDelayMillis(INITIAL_DELAY_MILLIS);
        listView.setAdapter(animAdapter);
        /* Enable drag and drop functionality */
        listView.enableDragAndDrop();
        listView.setDraggableManager(new           TouchViewDraggableManager(R.id.list_row_draganddrop_touchview));
        listView.setOnItemMovedListener(new MyOnItemMovedListener(adapter));
        listView.setOnItemLongClickListener(new MyOnItemLongClickListener(listView));
        /* Enable swipe to dismiss */
        listView.enableSimpleSwipeUndo();
        /* Add new items on item click */
        //listView.setOnItemClickListener(new MyOnItemClickListener(listView));

final ArrayAdapter adapter=新的MyListAdapter（此，R.layout.text\u视图，productsDef）；
SimplesWipesUndoAdapter SimplesWipesUndoAdapter=新SimplesWipesUndoAdapter（适配器，此，新MyOnDismissCallback（适配器））；
AlphaInAnimationAdapter animAdapter=新的AlphaInAnimationAdapter（SimpleSweepUndoAdapter）；
animAdapter.setAbsListView（listView）；
断言animAdapter.getViewAnimator（）！=无效的
animAdapter.getViewAnimator（）.setInitialDelayMillis（INITIAL_DELAY_MILLIS）；
setAdapter（animAdapter）；
/*启用拖放功能*/
enableDragAndDrop（）；
setDragableManager（新的TouchViewDragableManager（R.id.list\u row\u draganddrop\u touchview））；
setOnItemMovedListener（新的MyOnItemMovedListener（适配器））；
setOnItemLongClickListener（新的MyOnItemLongClickListener（listView））；
/*启用刷卡以关闭*/
EnableSimpleSweepUndo（）；
/*在项目上添加新项目单击*/
//setOnItemClickListener（新的MyOnItemClickListener（listView））；

在文档is中-对于timedUndoAdapter，请使用timedUndoAdapter。但当我尝试创建适配器时，出现错误：

Error:(249, 51) error: constructor TimedUndoAdapter in class TimedUndoAdapter cannot be applied to given types;
required: V,Context,OnDismissCallback
found: ArrayAdapter<Product>,DefaultProductsListUserEdit,DefaultProductsListUserEdit.MyOnDismissCallback
reason: inferred type does not conform to declared bound(s)
inferred: ArrayAdapter<Product>
bound(s): BaseAdapter,UndoAdapter
where V is a type-variable:
V extends BaseAdapter,UndoAdapter declared in constructor <V>TimedUndoAdapter(V,Context,OnDismissCallback)

Error:（249,51）Error:TimedUndoAdapter类中的构造函数TimedUndoAdapter不能应用于给定类型；
必需：V、上下文、OnDismissCallback
找到：ArrayAdapter、DefaultProductsListUserEdit、DefaultProductsListUserEdit.MyOnDismissCallback
原因：推断的类型不符合声明的绑定
推断：ArrayAdapter
绑定：BaseAdapter、UndoAdapter
其中V是一个类型变量：
V扩展BaseAdapter，在构造函数TimedUndoAdapter中声明的UndoAdapter（V，上下文，OnDismissCallback）

我不能对自定义对象使用TimedAdapter，或者我必须重写某些方法

这是myAdapter：

public class MyListAdapter extends ArrayAdapter<Product> implements UndoAdapter {

    private final Context mContext;
    HashMap<Product, Integer> mIdMap = new HashMap<Product, Integer>();
    ArrayList<Product> products = new ArrayList<Product>();
    final int INVALID_ID = -1;
    LayoutInflater lInflater;

    public MyListAdapter(Context context, int textViewResourceId, List<Product> prod) {
        //super(context, textViewResourceId, prod);
        super(prod);
        lInflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mContext = context;
        for (int i = 0; i < prod.size(); i++) {
            //add(prod.get(i));
            mIdMap.put(prod.get(i),i);
        }
    }

    @Override
    public long getItemId(final int position) {
        //return getItem(position).hashCode();
        Product item = (Product) getItem(position);
        return mIdMap.get(item);
    }

    @Override
    public boolean hasStableIds() {
        return true;
    }

    @Override
    public View getView(final int position, final View convertView, final ViewGroup parent) {
        //TextView view = (TextView) convertView;
        View view = convertView;
        if (view == null) {
            //view = (TextView) LayoutInflater.from(mContext).inflate(R.layout.list_row, parent, false);
            view = lInflater.inflate(R.layout.item, parent, false);
        }

        Product p = getItem(position);

        //view.setText(getItem(position).getProductName());
        ((TextView) view.findViewById(R.id.tvDescr)).setText(p.getProductName());

        return view;
    }

    @NonNull
    @Override
    public View getUndoView(final int position, final View convertView, @NonNull final ViewGroup parent) {
        View view = convertView;
        if (view == null) {
            //view = LayoutInflater.from(mContext).inflate(R.layout.undo_row, parent, false);
            view = lInflater.inflate(R.layout.undo_row, parent, false);
        }
        return view;
    }

    @NonNull
    @Override
    public View getUndoClickView(@NonNull final View view) {
        return view.findViewById(R.id.undo_row_undobutton);
    }

    public View getHeaderView(final int position, final View convertView, final ViewGroup parent) {
        TextView view = (TextView) convertView;
        //View view = convertView;
        if (view == null) {
            //view = (TextView) LayoutInflater.from(mContext).inflate(R.layout.list_header, parent, false);
            //view = lInflater.inflate(R.layout.list_header, parent, false);
        }

        //view.setText(mContext.getString(R.string.header, getHeaderId(position)));

        return view;
    }

    public long getHeaderId(final int position) {
        return position / 10;
    }
}
