本文介绍了Android的基础适配器不适配器的所有行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有两个日期时间2014年12月1日和12/10 / 2014.i改变日期时间格式，我还检查了不同的有两个日期时间，我也有增加之间的天datetimes.for更多信息12月1日，12月2日，12月3日..... 12月10日这是我的源

I have two datetimes 12/01/2014 and 12/10/2014.i changed datetime format and i also checked different between there two datetime and i also incremented days between there datetimes.for more information 1 dec,2 dec,3 dec .....10 dec this is a my source

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(); } @SuppressLint("SimpleDateFormat") @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); 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("starttime1", timeInfo.getTimeformat().get(MainmoviesList.mPosition)); Log.wtf("endtime1", timeInfo.getEndTimeFormat().get( MainmoviesList.mPosition)); SimpleDateFormat df = new SimpleDateFormat("MM/dd/yyyy"); Date _d; try { SimpleDateFormat new_df = new SimpleDateFormat("d MMM"); _d = df.parse(timeInfo.getTimeformat().get( MainmoviesList.mPosition)); Date _d1 = df.parse(timeInfo.getEndTimeFormat().get( MainmoviesList.mPosition)); 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(MainmoviesList.mPosition)); 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baseadapter XML code

} this is a my baseadapter xml code

<RelativeLayout xmlns:android="schemas.android/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:background="@android:color/transparent" > <TextView android:id="@+id/adapter_day" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBottom="@+id/imageView1" android:layout_alignLeft="@+id/imageView1" android:layout_alignRight="@+id/imageView1" android:layout_marginBottom="15dp" android:gravity="center" android:paddingLeft="5dp" android:text="day" android:textColor="#c42a29" android:textSize="13dp" /> <ImageView android:id="@+id/imageView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignRight="@+id/imageView1" android:layout_below="@+id/adapter_day" android:layout_marginRight="25dp" android:background="@drawable/justline" /> <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="22dp" android:background="@drawable/adapter_circle" /> </RelativeLayout>

我logend，我可以显示在日志中的所有信息。这是我的日志猫结果（我是新用户，我不能张贴图片）在我的选择，我有我的baseadapter问题，因为在我的适配器只能显示第一日期时间（1 DEC）这是我的基本适配器code

i logend and i can show all information in log.this is a my log cat result (i'm new user and i can't post image) in my option i have problem in my baseadapter because in adapter i can show only first datetime(1 dec) this is a my base adapter code

public class HollAdapters extends BaseAdapter { private Context mContext; private final ArrayList<CinemaInfoModel> hollitems; public HollAdapters(Context context, ArrayList<CinemaInfoModel> hollitems) { mContext = context; this.hollitems = hollitems; } @Override public int getCount() { return hollitems.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 = hollitems.get(position); if (objectItem != null) { if (position < objectItem.getStartTimePeriod().size()) { String starttimes = objectItem.getStartTimePeriod().get( position); viewHolder.start_time.setText(starttimes); } } return convertView; } static class ViewHolderItem { private TextView start_time; }

}

这是我divice的截图正如我所说的，我可以只显示日期时间先1 Dec.i不知道什么是我baseadapter.if任何一个错误都知道的解决方案，请帮助我谢谢

this is a my divice's screenshot as i said i can show only first datetime 1 Dec.i have no idea what is a wrong in my baseadapter.if anyone knows solution please help me thanks

推荐答案

删除围绕ViewHolder提取}其他块。移动支架初始化到如果{块之后。现在尝试。

Remove the } else block around the ViewHolder extraction. Move the Holder initialization to after the if{ block. And try now.

if (convertView == null) { LayoutInflater inflater = ((Activity) mContext).getLayoutInflater(); convertView = inflater.inflate(R.layout.cinema_holl_adapter, parent, false); ViewHolderItem newViewHolder = new ViewHolderItem(); newViewHolder.start_time = (TextView) convertView .findViewById(R.id.adapter_day); convertView.setTag(newViewHolder); } ViewHolderItem viewHolder = (ViewHolderItem) convertView.getTag(); //This should be called always /* Rest of your code */

编辑：这是什么块呢？

What does this block do?

if (position < objectItem.getStartTimePeriod().size()) { String starttimes = objectItem.getStartTimePeriod().get( position); viewHolder.start_time.setText(starttimes); }
