现在调用日志列表视图屏幕截图

我只是不想在我的数据库中重复值。因此，我的列表视图中将一次显示一个联系人姓名，并且我还希望与其号码关联的呼叫数量。通过查询插入数据库时，我可以通过使用唯一关键字获得独特的价值，但我没有任何关于计算我从该数字得到的电话的信息。

我正在使用以下代码从数据库中获取调用日志。现在我只是访问通话记录并显示它。我没有存储在数据库中。我不知道如何计算来自特定号码的呼叫数量并将其显示在前面。它显示在呼叫日志应用程序中。

      Cursor callLogCursor = getContentResolver().query(
            android.provider.CallLog.Calls.CONTENT_URI, null, null, null,
            android.provider.CallLog.Calls.DEFAULT_SORT_ORDER);
    if (callLogCursor != null) {
        while (callLogCursor.moveToNext()) {
            String id = callLogCursor.getString(callLogCursor
                    .getColumnIndex(CallLog.Calls._ID));
            String name = callLogCursor.getString(callLogCursor
                    .getColumnIndex(CallLog.Calls.CACHED_NAME));
            String cacheNumber = callLogCursor.getString(callLogCursor
                    .getColumnIndex(CallLog.Calls.CACHED_NUMBER_LABEL));
            String number = callLogCursor.getString(callLogCursor
                    .getColumnIndex(CallLog.Calls.NUMBER));
            long dateTimeMillis = callLogCursor.getLong(callLogCursor
                    .getColumnIndex(CallLog.Calls.DATE));
            long durationMillis = callLogCursor.getLong(callLogCursor
                    .getColumnIndex(CallLog.Calls.DURATION));
            int callType = callLogCursor.getInt(callLogCursor
                    .getColumnIndex(CallLog.Calls.TYPE));

            String duration = getDuration(durationMillis * 1000);

            String dateString = getDateTime(dateTimeMillis);


            if (cacheNumber == null)
                cacheNumber = number;
            if (name == null)
                name = "";
            Uri image = null;

            try {
                String conId = fetchContactIdFromPhoneNumber(cacheNumber);
                long contId = Long.parseLong(conId);
                image = getPhotoUri(contId);
            }catch(Exception e) {
                Log.e("Exception", e.getMessage());
            }


                CallLogModel callLogModel = new CallLogModel(image, name, cacheNumber,
                        duration, dateString);


            if (callType == CallLog.Calls.OUTGOING_TYPE) {
                outgoingList.add(callLogModel);

            } else if (callType == CallLog.Calls.INCOMING_TYPE) {
                incomingList.add(callLogModel);

            } else if (callType == CallLog.Calls.MISSED_TYPE) {
                missedcallList.add(callLogModel);

            }

        }

        callLogCursor.close();
    }
}

您可以尝试使用group by子句如下：

String[] columns = new String[] { CallLog.Calls._ID, CallLog.Calls.NUMBER, CallLog.Calls.CACHED_NAME };
Cursor cursor = getContentResolver().query(URI_CALL, columns, null, null, null);

呼叫日志列表视图中没有重复
