我从php文件中获取数据，需要在listView上显示，扩展Fragment。
抛出onPostExecute（）时出错：
The constructor SimpleAdapter(Commodities, ArrayList>, int, String[], int[]) is undefined
问题在于我的AsyncTask的onPostExecute（）：
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
ListAdapter adapter = new SimpleAdapter(Commodities.this,
matchFixtureList, R.layout.list_item, new String[] {
TAG_SCRIPT, TAG_BUYSELL, TAG_TRADESELL, TAG_TARGET,
TAG_STOPLOSS, TAG_STATUS }, new int[] {
R.id.Script, R.id.BuySell, R.id.TradeSell,
R.id.Target, R.id.StopLoss, R.id.Status });
setListAdapter(adapter);
}
如何解决此错误？这是全班代码：
public class Commodities extends Fragment {
private String URL_ITEMS = "http://ourvadodara.ddns.net/NeptuneFinsol/commodities_fetch.php";
private static final String TAG_COMMODITIES = "commodities";
private static final String TAG_DATE = "date";
