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();
} …我正在使用ListView的自定义适配器,其中我有一个TextView和一个Spinner.从Spinner中选择值后,将该值复制到相应行列表的TextView之后.
问题是,由于我在ListView中有超过40个元素,当我选择第一个微调器并将值设置为相应的TextView时,在滚动时,在第10行TextView中可以看到相同的值.
在滚动时将值从第1个TextView复制到第10个TextView.
以下是我使用的代码:
public class AppListAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private List<App> mApps = Constants.list;
private Context _activity;
ArrayList<String> months=null;
ArrayAdapter<String> dataAdapter =null;
int spinerposition;
int viewposition;
int temp=0;
private int screenWidth;
/**
* Constructor.
*
* @param context the application context which is needed for the layout inflater
* @param screenWidth
*/
public AppListAdapter(Context context, int screenWidth) {
// Cache the LayoutInflate to avoid asking for a new one each time.
mInflater = LayoutInflater.from(context);
this._activity=context;
this.screenWidth …
