Question

我有baseadapter，我尝试在listview.i loged字符串中适配一些值，我在baseadapter中调整了我和我有不同的结果。在BaseAdapter类也传递这个文本，这两个文本是不同的这是我的主要Java源代码

public class MoviesRolls extends Fragment {

public final static String TAG = MoviesRolls.class.getSimpleName();

private ListView holllistview;
private HollAdapters adapter;
public static ArrayList<CinemaInfoModel> cinemaInfoArray;
public static CinemaInfoModel timeInfo;


public static MoviesRolls newInstance() {
return new MoviesRolls();}


public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {

View rootView = inflater
        .inflate(R.layout.moviesholls, container, false);

holllistview = (ListView) rootView.findViewById(R.id.holllistview);

holllistview = (ListView) rootView.findViewById(R.id.holllistview);



ServerItems mainItem = MainmoviesList.arrayOfList
        .get(MainmoviesList.mPosition);

ArrayList<CinemaModel> cinemas = mainItem.getCinema();
ArrayList<CinemaInfoModel> infos = new ArrayList<CinemaInfoModel>();
for (int i = 0; i < cinemas.size(); i++) {
    CinemaModel cinema = cinemas.get(i);
    cinemaInfoArray = cinema.getCinemTimeInfo();
    for (int j = 0; j < cinemaInfoArray.size(); j++) {
        timeInfo = cinemaInfoArray.get(j);

        Log.wtf("logcat start time",
                timeInfo.getTimeformat().get(j));
        Log.wtf("log cat end time",
                timeInfo.getEndTimeFormat().get(
                        j));

        SimpleDateFormat df = new SimpleDateFormat("MM/dd/yyyy");
        Date _d;
        try {
            SimpleDateFormat new_df = new SimpleDateFormat("d MMM");
            _d = df.parse(timeInfo.getTimeformat().get(
                    j));
            Date _d1 = df.parse(timeInfo.getEndTimeFormat().get(
                   j));
            String datetimeis = getDateDiffString(_d1, _d);
            int differentdays = Integer.parseInt(datetimeis);
            Log.e("Different is ", String.valueOf(differentdays));
            for (int k = 0; k < differentdays; k++) {

                String datetimeformat = dateFormatter(timeInfo
                        .getTimeformat().get(j));

                Date datetime = new_df.parse(datetimeformat);

                Calendar cal = Calendar.getInstance();
                cal.setTime(datetime);
                cal.add(Calendar.DATE, k);

                datetime = cal.getTime();

                String ttime = new_df.format(datetime);
                timeInfo.setStartTimePeriod(ttime);
                System.out.println(ttime);
            infos.add(timeInfo);
            }
        } catch (ParseException e) {

            e.printStackTrace();
        }


    }

    adapter = new HollAdapters(getActivity(), infos);
    holllistview.setAdapter(adapter);

}
return rootView;
}

   public String getDateDiffString(Date dateOne, Date dateTwo) {
   long timeOne = dateOne.getTime();
   long timeTwo = dateTwo.getTime();
   long oneDay = 1000 * 60 * 60 * 24;
   long delta = (timeTwo - timeOne) / oneDay;

   if (delta > 0) {

    for (int i = 0; i < delta; i++) {

    }
    return String.valueOf(delta);
} else {
    delta *= -1;
    return String.valueOf(delta);
    }
  }


public static String dateFormatter(String inputDate) {

String inputFormat = "MM/dd/yyyy";
String outputFormat = "d MMM";

Date parsed = null;
String outputDate = "";
try {
    SimpleDateFormat df_input = new SimpleDateFormat(inputFormat,
            new Locale("en", "US"));
    SimpleDateFormat df_output = new SimpleDateFormat(outputFormat,
            new Locale("en", "US"));

    parsed = df_input.parse(inputDate);
    outputDate = df_output.format(parsed);

    // Log.wtf("outputDate", outputDate);
} catch (Exception e) {
    outputDate = inputDate;
}
return outputDate;
  }
 }

这是我的基本适配器代码

public class HollAdapters extends BaseAdapter {
private Context mContext;

private final ArrayList<CinemaInfoModel> hollitems1;

public HollAdapters(Context context, ArrayList<CinemaInfoModel> hollitems) {
    mContext = context;

    this.hollitems1 = hollitems;

}

@Override
public int getCount() {

    return hollitems1.size();
}

@Override
public Object getItem(int position) {

    return null;
}

@Override
public long getItemId(int position) {

    return position;
}

@SuppressLint("ViewHolder")
@Override
public View getView(int position, View convertView, ViewGroup parent) {

    ViewHolderItem viewHolder;

    if (convertView == null) {

        LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
        convertView = inflater.inflate(R.layout.cinema_holl_adapter,
                parent, false);

        viewHolder = new ViewHolderItem();
        viewHolder.start_time = (TextView) convertView
                .findViewById(R.id.adapter_day);

        convertView.setTag(viewHolder);

    } 
    viewHolder = (ViewHolderItem) convertView.getTag();

    CinemaInfoModel objectItem = hollitems1.get(position);
    if (objectItem != null) {




            String starttimes = objectItem.getStartTimePeriod().get(
                    position);


            viewHolder.start_time.setText(starttimes);
            Log.e("adapter start time", starttimes);



    }

    return convertView;

}

static class ViewHolderItem {
    private TextView start_time;

 }
}

this is a my logcat message's screenshot（我是新用户，我无法发布图片）

我不知道我的代码中有什么问题......如果有人知道解决方案，请帮助我感谢

试试这个，请改变你这样的代码。如果convertView为null意味着它将使布局膨胀，否则它将重用该视图。如果您需要任何澄清，请告诉我

  if (convertView == null) {

    LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
    convertView = inflater.inflate(R.layout.cinema_holl_adapter,
            parent, false);

    viewHolder = new ViewHolderItem();
    viewHolder.start_time = (TextView) convertView
            .findViewById(R.id.adapter_day);

    convertView.setTag(viewHolder);

}else{
viewHolder = (ViewHolderItem) convertView.getTag();
}
/*** Do your stuff here***/

android baseadapter没有正确
