Question

我有一个扩展BaseAdapter的ListView。我有一个数组列表。 ListView正确地膨胀和填充。我正在使用翻板视图将布局更改为另一个，但问题是当我点击它旋转的第一个项目但第三行或第六行的项目也将旋转列表视图如何修复它我只希望图像是所选项目的更改

    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;

    }
}

在arraylist中添加数据

try {
                JSONObject parentObject = new JSONObject(json.toString());
                JSONObject userDetails = parentObject.getJSONObject("response"); 
                JSONArray jarray=userDetails.getJSONArray("products_data");
                   for(int i=0;i<jarray.length();i++)
                   {
                       System.out.println("From the Dataaaa");
                       JSONObject c = jarray.getJSONObject(i);
                       String details=c.getString("details");
                       String image=c.getString("image");
                       String catagory=c.getString("catagory");
                       String new_price=c.getString("new_price");
                       String title=c.getString("title");
                       String id1=c.getString("id");
                       System.out.println("from ther first image"+image);
                       System.out.println("from the sdafdfadf"+details);

                       al.add(new product_data(title, new_price, new_price, image, id1));

适配器类

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());

当我点击它旋转的第一个项目而另一个视图即将到来时

但是当我滚动下面图像中的第四个项目时也会旋转

我在相对视图中使用on click listner，如代码

使用ViewHolder填充适配器。这可能会解决您的问题

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;


    }

}
