我正在开发一个BaseAdaper。我正试图在ListView中添加一些信息。
p.S我有两个日期时间，我检查了不同的日期时间，并尝试在ListView中添加如下内容：这两个日期是9月2日和9月5日，我尝试添加2月、3月、4月、5月
我写了一些代码，但每次在ListView中只添加了5个sep。这是我的baseadaper代码：
public class HollAdapters extends BaseAdapter {
private Context mContext;
private final ArrayList<CinemaInfoModel> hollitems;
//private CinemaInfoModel objBean;
private TextView start_time,holle,time;
private static LayoutInflater inflater = null;
public HollAdapters(Context context, ArrayList<CinemaInfoModel> hollitems) {
mContext = context;
this.hollitems = hollitems;
inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return hollitems.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@SuppressLint("ViewHolder")
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View grid;
grid = new View(mContext);
grid = inflater.inflate(R.layout.cinema_holl_adapter, null);
start_time = (TextView) grid.findViewById(R.id.adapter_day);
holle = (TextView) grid.findViewById(R.id.adapter_holl);
time = (TextView) grid.findViewById(R.id.adapter_time);
//objBean = hollitems.get(position);
start_time.setText(hollitems.get(position).getStartTime());
Log.wtf("adapter time ", hollitems.get(position).getStartTime());
holle.setText(hollitems.get(position).getHole());
String start_time=hollitems.get(position).getTime();
start_time=start_time.replace(",", "n");
time.setText(start_time);
return grid;
}
}
这是我的主要代码的一部分：
for (int j = 0; j < cinemasJsonArray.length(); j++) {
CinemaModel cinema = new CinemaModel();
cinema.setName(cinemasJsonArray.getJSONObject(j)
.getString("cinemaName"));
JSONArray timeJsonArray = cinemasJsonArray
.getJSONObject(j).getJSONArray("info");
cinemaInfoArray = new ArrayList<CinemaInfoModel>();
for (int k = 0; k < timeJsonArray.length(); k++) {
CinemaInfoModel cinemaTime = new CinemaInfoModel();
cinemaTime.setTime(timeJsonArray.getJSONObject(k)
.getString("time"));
cinemaTime.setHole(timeJsonArray.getJSONObject(k)
.getString("hole"));
SimpleDateFormat df = new SimpleDateFormat(
"MM/dd/yyyy");
Date _d = df.parse(timeJsonArray.getJSONObject(k)
.getString("start_time"));
Date _d1 = df.parse(timeJsonArray.getJSONObject(k)
.getString("end_time"));
SimpleDateFormat new_df = new SimpleDateFormat(
"d MMM");
String datetimeis = getDateDiffString(_d1, _d);
Log.wtf("differentis ", datetimeis);
int abc = Integer.parseInt(datetimeis);
for (int l = 0; l < abc; l++) {
String ab = dateFormatterforLukka(timeJsonArray
.getJSONObject(k).getString(
"start_time"));
SimpleDateFormat df2 = new SimpleDateFormat(
"d MMM");
Date datetime = df2.parse(ab);
Calendar cal = Calendar.getInstance();
cal.setTime(datetime);
cal.add(Calendar.DATE, l);
datetime = cal.getTime();
String ttime = new_df.format(datetime);
cinemaTime.setStartTime(ttime);
Log.wtf("timeeeeeeeee", ttime);
cinemaInfoArray.add(cinemaTime);
}
}
cinema.setCinemTimeInfo(cinemaInfoArray);
cinemasArrayList.add(cinema);
}
movie.setCinema(cinemasArrayList);
arrayOfList.add(movie);
}
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 dateFormatterforLukka(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;
}
我以这种方式调整了ListView：
public class MoviesRolls extends Fragment {
public final static String TAG = MoviesRolls.class.getSimpleName();
private ListView holllistview;
private HollAdapters adapter;
public static ArrayList<CinemaInfoModel> cinemaInfoArray;
private String title, category1, imdb;
public static TextView movies_title, category, imdbreting;
public static MoviesRolls newInstance() {
return new MoviesRolls();
}
@Override
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);
movies_title = (TextView) rootView.findViewById(R.id.movies_title1);
category = (TextView) rootView.findViewById(R.id.category1);
imdbreting = (TextView) rootView.findViewById(R.id.imdbreting1);
Bundle bundle = getArguments();
title = bundle.getString("title");
imdb = bundle.getString("imdb");
category1 = bundle.getString("category");
imdbreting.setText(imdb);
imdbreting.setText(imdb);
movies_title.setText(title);
category.setText(category1);
adapter = new HollAdapters(getActivity(), MainmoviesList.cinemaInfoArray);
holllistview.setAdapter(adapter);
adapter.notifyDataSetChanged();
;
return rootView;
}
正如我所说，如果我的两天时间是9月2日和5日，总是会添加3日和4日，尽管日志看起来还可以。
Log.wtf("timeeeeeeeee", ttime)
我做错了什么？如果有人知道解决方案，请帮助我
感谢
尝试更改：
@Override
public int getCount() {
return hollitems.size();
}
@Override
public Object getItem(int position) {
return hollitems.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
