我试图用名称保存我的文件作为当前日期和时间(以毫秒为单位).在阅读文件时,我想阅读最新版本.这是代码

 Calendar rightNow = Calendar.getInstance();

  long offset = rightNow.get(Calendar.ZONE_OFFSET) +  rightNow.get(Calendar.DST_OFFSET);

  String sinceMidnight = Long.toString((rightNow.getTimeInMillis() + offset) %  (24 * 60 * 60 * 1000));

  return sinceMidnight+"_"+Filename;

我正在尝试验证日期时间格式MM/DD/YYYY.这是我正在尝试的代码请帮助.

 function ValidateDate(testdate) {
        var Status
        var reg = /^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$/g;
        if (!reg.test(testdate)) {
            Status = false;
        }
        return Status;
    }

我正在尝试将所有联系人都放在.csv文件中.我已经完成了获取联系人的第一部分,我现在剩下的就是将文件写入.csv文件.请告诉我如何在android中创建.csv文件.

我正在尝试在我的应用程序中开发警报功能,该应用程序在固定时间由用户指定的工作日运行.这里的问题是我的调度程序运行了所有天而不是在指定的一天运行.这是我为此写的代码请帮助解决这个问题

Calendar calNow = Calendar.getInstance();
                SimpleDateFormat simpDate;
                simpDate = new SimpleDateFormat("kk:mm:ss");
                if(in_Date==1)
                {
                    calNow.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    calNow.set(Calendar.MINUTE, minute);
                    calNow.set(Calendar.SECOND, 0);
                    calNow.set(Calendar.MILLISECOND, 0);
                }
            else if(in_Date==2)
                {
                    calNow.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    calNow.set(Calendar.MINUTE, minute);
                    calNow.set(Calendar.SECOND, 0);
                    calNow.set(Calendar.MILLISECOND, 0);
                    calNow.set(Calendar.DAY_OF_WEEK,in_SelectedDay);
                }
                etTime.setText(simpDate.format(calNow.getTime()));
                Seconds=calNow.getTimeInMillis();

private void setAlarm(){

    //etTime.setText(simpDate.format(calNow.getTime()));

    Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

     if(in_Date==1)
     {

       alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, Seconds,alarmManager.INTERVAL_DAY,pendingIntent);
     }
    else if(in_Date==2)
    {

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, Seconds,1 * 60 * 60 * 1000,pendingIntent);
    }

}

我通过在单独的文本框中输入日期,从下拉列表中选择年份并在文本框中输入年份来输入出生日期.现在我想检查输入的日期不能大于jquery中的当前日期.请帮忙怎么样？

var CurrentMonth = date.getDate() + '/' + date.getMonth() + '/' + date.getFullYear();
    var SelectedDate = $('[id$=spDate]').val() + '/' + $('[id$=drpMonth]').val() + '/' + $('[id$=txtYear]').val();
    if (CurrentDate > SelectedDate) {
        return false;
    } 

我在 onCreate() 方法的第一个活动上创建应用程序文件夹，但文件夹没有创建。这是代码

 if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
        File fil = new File(this.getFilesDir().getPath()+File.separator+"MyContactsBackUp");
        fil.mkdirs();

} else {
    File directory = new File(Environment.getExternalStorageDirectory()+File.separator+"MyContactsBackUp");
    directory.mkdirs();
}

虽然在2008年的VS 2012投掷异常时以M/d/yyyy格式传递日期,但在2008年工作正常请建议如何解决此问题.下面是代码

 String date = drpMonth.SelectedItem.Value + "/" + drpDay.SelectedItem.Value + "/" + drpYear.SelectedItem.Value;
            try
            {


                objUsers.DateOfBirth = Convert.ToDateTime(date);
            }

我是android的新手,我想获取联系人并在列表视图中显示.这是我在asynctask.please中获取联系人的代码,帮助我们在获取每个联系人后更新列表视图.

protected Void doInBackground(Void... params) {
         ContentResolver cr = ReadContactsActivity.this.getContentResolver();
         Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
                null, null, null, null);

         if (cur.getCount() > 0) {
             while (cur.moveToNext()) {
                 String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                 String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                 if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                     Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
                                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                                            new String[]{id}, null);
                     while (pCur.moveToNext()) {
                           String phone = pCur.getString(
                                  pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        //li.add("Name:"+name+",Number:"+phone);
                           publishProgress("Name:"+name+",Number:"+phone);
                     }
                     pCur.close();
                     }
                 }
             }
        return null;
    }
