在我的应用程序中我使用自定义列表视图适配 在列表视图项中,我添加了另一个布局.因为在我的服务中,一个订单有任意数量的订单商品.为了显示订单项目,我将下面的订单商品布局添加到自定义列表视图item.it工作正常.但滚动列表视图时,数据会发生变化.

适配器类:

public class PreviousDataAdapter extends BaseAdapter {
    ArrayList<PreviousOrderData> bpData;
    private ArrayList<PreviousOrderData> arraylist;
    ArrayList<OrderItemData> opData;
    private ArrayList<OrderItemData> arraylist1;
    private Activity activity;
    private LayoutInflater inflater;
    String g_orderid;
    DatabaseHandler db;
    SharedPreferences m_sharedPreference;
    SharedPreferences.Editor m_editor;

    ArrayList<String> circless = new ArrayList<String>();

    public PreviousDataAdapter(Activity activity, ArrayList<PreviousOrderData> bpData,ArrayList<OrderItemData> opdata) {
        // TODO Auto-generated constructor stub
        this.activity = activity;
        this.bpData = bpData;
        this.opData=opdata;//k?

       // this.opData=bpData.get()//opdata;
        inflater = LayoutInflater.from(activity);
        db = new DatabaseHandler(activity);

    }


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