Xamarin C＃Android通话记录

我的设备的通话记录有问题。代码根本没有返回日志，它给出了错误的数据。Xamarin C＃Android通话记录

代码：

public void ReadCalls() 
    { 
     try { 
      Android.Content.Context myContext = Android.App.Application.Context; 
      string myDateToCheck = myServiceRef.myTimeToCheck("CallLog"); 
      if (myDateToCheck==null || myDateToCheck=="") 
      {myDateToCheck = "0";} 

      ICursor cursor = myContext.ContentResolver.Query( Android.Net.Uri.Parse ("content://call_log/calls"), null, "Date > ?", new string[]{myDateToCheck }, "Date ASC"); 
      if (cursor.MoveToFirst()) { 
       while (!cursor.IsAfterLast) { 
        if (cursor.GetLong (cursor.GetColumnIndex (CallLog.Calls.Date)) > long.Parse (myDateToCheck)) { 
         string Number = cursor.GetString (cursor.GetColumnIndex (CallLog.Calls.Number)); 
         string Name = cursor.GetString (cursor.GetColumnIndex (CallLog.Calls.CachedName)); 
         if (Name == null || Name == "") { 
          Name = "Unknown"; 
         } 
         string Date = cursor.GetString (cursor.GetColumnIndex (CallLog.Calls.Date)); 
         string Duration = cursor.GetString (cursor.GetColumnIndex (CallLog.Calls.Duration)); 
         string Type = cursor.GetString (cursor.GetColumnIndex (CallLog.Calls.Type)); 
         if (Number == "0") { 
          Number = "Unknown"; 
         } else if (Number == "-1") { 
          Number = "Unknown"; 
         } 
         long num = long.Parse (Date); 
         Java.Text.SimpleDateFormat simpleDateFormat = new Java.Text.SimpleDateFormat ("yyyy-MM-dd HH:mm:ss"); 
         DateTime dateTime = new DateTime (1970, 1, 1).AddMilliseconds ((double)num); 
         dateTime = dateTime.AddMilliseconds (simpleDateFormat.TimeZone.GetOffset (num)); 
         if (Type == "1") { 
          Type = "Outgoing"; 
         } else if (Type == "2") { 
          Type = "Incoming"; 
         } else if (Type == "3") { 
          Type = "Missed Call"; 
         } 
         // now need to write it to a database 


         MyCallLog myLine = new MyCallLog { 
          TheNumber = Number , 
          TheName = Name , 
          TheTime = dateTime.ToString() , 
          TheDirection = Type , 
          TheDuration = Duration 
         }; 
         string output = Newtonsoft.Json.JsonConvert.SerializeObject (myLine); 
         myServiceRef.myDatabaseConnection (output); 
        } else { 
         break; 
        } 
        cursor.MoveToNext(); 
       } 
      } 

     }catch{ 


     } 
    }

的数量始终是 “-1”。该名称始终为空，且始终为传出呼叫。

它给出了一个日期戳但不准确。

DB搜索的很多之后，我发现这个URI只存储最新的数据，完整的历史并不存储在URI，它在其他地方..固定我的时间问题，为什么-1，但我需要找到如何获取所有的历史记录，所有在网上的例子不包括这 – Migz

//static class to convert milisecond to datetime  
static class ConvertToDate 
{ 
    static readonly DateTime UnixEpochStart = DateTime.SpecifyKind(new DateTime(1970, 1, 1), DateTimeKind.Utc); //Coverting date in to universal 

    public static DateTime ToDateTimeFromEpoch(this long epochTime) 
    { 
     DateTime result = UnixEpochStart.AddMilliseconds(epochTime); 
     return result; 
    } 
}

以上代码可能对您有所帮助。我也是Xamarin及以上代码给出了我适当的日期时间。如果您有任何疑问，请让我知道。

包括使用calllog = Android.Provider.CallLog.Calls;在命名空间 –
