Question

我的listview中有10个新条目从一个edittext动态添加，今天的日期为12-13-2013我无法弄清楚为什么明天所有的日期都会读到12-14-2013我希望每个条目保留日期进入并且没有改变任何想法？

class ViewHolder {
    TextView gump;
    ImageView pic;
    TextView day;
    ImageView more;

    ViewHolder(View v) {
        gump = (TextView) v.findViewById(R.id.inputLrgtxt);
        pic = (ImageView)v.findViewById(R.id.sexpic);
        day = (TextView)v.findViewById(R.id.holla);
    }
}

private class KoreyzAdapter extends ArrayAdapter<ArgueItem> {
    private ArrayList<ArgueItem> argueList;
    private Context context;

    public KoreyzAdapter(Context c, int textViewResourceId, ArrayList<ArgueItem> argueList) {
        super(c, textViewResourceId, argueList);
        this.argueList = argueList;
        this.context = c;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        ViewHolder holder = null;
        long msTime = System.currentTimeMillis();
        Date date = new Date(msTime);
        SimpleDateFormat sdf = new SimpleDateFormat("M/d/y");
        String biggie = sdf.format(date);

        if(row == null) {
            LayoutInflater inflator = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = inflator.inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder(row);
            row.setTag(holder);
        }
        else {
            holder = (ViewHolder)row.getTag();
        }

        holder.gump.setText(argueList.get(position));
        holder.day.setText(biggie);

        return row;
    }
}

您的代码：

        long msTime = System.currentTimeMillis();
        Date date = new Date(msTime);
        SimpleDateFormat sdf = new SimpleDateFormat("M/d/y");
        String biggie = sdf.format(date);

呈现列表视图时会调用

。因此，您正在创建一个反映当前日期（即呈现时的日期）的新日期。

如果您想要一个永不改变的日期，请计算一次并坚持下去（SharedPreferences将是一个不错的选择）。然后在将来的调用中，从SharedPreferences中读取日期字符串。

Android SimpleDateFormat日期在新的一天更改
