Question

我创建了一个Android应用程序，因为我想要号码的最后通话详细信息。

使用 CallLog.Calls.DURATION 我收到最后一个通话详情。

我的代码是 -

    StringBuffer sb = new StringBuffer();
    Uri contacts = CallLog.Calls.CONTENT_URI;
    Cursor managedCursor = context.getContentResolver().query(contacts, null, null, null, null);
    int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
    int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
    int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
    int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
    sb.append("Call Details :");

    if(managedCursor.moveToFirst())
    {
        String phNumber = managedCursor.getString(number);
        String callType = managedCursor.getString(type);
        String callDate = managedCursor.getString(date);
        String callDayTime = new Date(Long.valueOf(callDate)).toString();
        // long timestamp = convertDateToTimestamp(callDayTime);
        String callDuration = managedCursor.getString(duration);
        int calld=Integer.parseInt(callDuration);

        String dir = null;
        int dircode = Integer.parseInt(callType);
        switch (dircode) {
        case CallLog.Calls.OUTGOING_TYPE:
            dir = "OUTGOING";
            break;

        case CallLog.Calls.INCOMING_TYPE:
            dir = "INCOMING";
            break;

        case CallLog.Calls.MISSED_TYPE:
            dir = "MISSED";
            break;
        }
        sb.append("\nPhone Number:--- " + phNumber + " \nCall Type:--- " + dir + " \nCall Date:--- " + callDayTime + " \nCall duration in sec :--- " + calld);
        sb.append("\n----------------------------------");            

    }

    managedCursor.close();
    System.out.println(sb);

在一台设备中，我使用managedCursor.moveToFirst()获取最后一个通话详情，在另一台设备中，我使用managedCursor.moveToLast()获取最后一个通话详情。

如何使用单一代码实现它？

您可以向查询添加ORDER BY子句，以便在调用时按顺序对它们进行排序。

Cursor managedCursor = context.getContentResolver().query(contacts, null, null, null, CallLog.Calls.DEFAULT_SORT_ORDER);

OR

Cursor managedCursor = context.getContentResolver().query(contacts, null, null, null, CallLog.Calls.DATE + " DESC");

CallLog.Calls.DURATION在不同的设备中给出不同的结果
