Android 适配器选择问题

我有一个扩展BaseAdapter的ListView。我有一个数组列表。ListView会正确膨胀和填充。我正在使用flipper视图将布局更改为其他布局，但问题是当我单击第一个项目时，它会旋转，但第三行或第六行的项目也会旋转 列表视图如何修复我只需要图像是选定项目的更改

    ArrayList<product_data> al=new ArrayList<product_data>();
class product_data
{
    String post_title;
    String newprice;
    String oldprice;
    String image;
    String id;
    product_data(String post_title,String newprice,String oldprice,String image,String id)
    {
        this.post_title=post_title;
        this.newprice=newprice;
        this.oldprice=oldprice;
        this.image=image;
        this.id=id;

    }
}

}

当我点击第一个项目时，它会旋转，另一个视图会出现

但当我滚动时，下图中的第四项也会旋转

我在相对视图上使用点击列表器，如代码“使用ViewHolder for fill adapter”中所示。那可能会解决你的问题

示例代码

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater mInflater = LayoutInflater.from(context);
        final ViewHolder holder;
        if (convertView == null) {

            convertView = mInflater.inflate(
                    R.layout.news_by_categories_content, null);
            holder = new ViewHolder();
            holder.strNewsTitle = (TextView) convertView
                    .findViewById(R.id.txtNewsByCategories);


            convertView.setTag(holder);

        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        NewsListByCategoriesItem obj = new NewsListByCategoriesItem(); // My Model class getting value from this
        obj = newsArray.get(position);
        holder.strNewsTitle.setText(obj.getStrNewsTitle());


        return convertView;
    }

    class ViewHolder {
        TextView strNewsTitle;


    }

}

您确实在getView方法中启动了动画！！！！，你知道它有多贵吗。该方法将在每次向上滚动查看下一个项目时调用。开始动画用于列表视图布局，但我关心的是项目布局检查回拨、翻转动画。我使用了已实现的3d旋转类

class MyAdapter extends BaseAdapter
{

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

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

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

    @Override
    public View getView(int position, View singleView, ViewGroup parent) {
        // TODO Auto-generated method stub
        final int ok=position;

        if(singleView==null)
        {
            LayoutInflater inflater = LayoutInflater.from(parent.getContext());
            singleView = inflater.inflate(R.layout.product_ist_layout,parent,false);
            System.out.println("from the if"+position);
            viewAnimator = (ViewAnimator)singleView.findViewById(R.id.viewFlipper);
             rootLayout = (View)singleView.findViewById(R.id.main_activity_root);

             cardBack = (View) singleView.findViewById(R.id.main_activity_card_back);
        }

            System.out.println("from the else");


        System.out.println("Position in else"+position);
