Question

我正在尝试在我的应用程序中实现以下功能。如果用户选择某个日期（开始日期），则我的应用程序将能够显示该特定日期之后和今天之前的未接来电，去电和来电计数。我已经实现了代码，如果我不放置任何过滤器，则它可以正常工作并正确计数所有呼叫日志。我已经使用IF条件块添加了dateFilter。但这不起作用。

我还尝试了相关问题中的一些方法，这些方法指示我们修改查询，但没有任何效果。您能帮我找到失踪的物品吗？这是我的功能。

/* Operation of Counting the call logs will be performed */
void performCount() {

        Cursor dataCursor = getApplicationContext().getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null,
                null);

        /* Date choosen by user, to get the Call logs after this date */

        Date startDate=new Date(2018,5,5);
        Toast.makeText(getApplicationContext(),startDate.toString(),Toast.LENGTH_SHORT).show();

        /* Tried Solution but it doesn't work */
        /*
        dataCursor = getApplicationContext().getContentResolver().query(CallLog.Calls.CONTENT_URI,
                new String[] { CallLog.Calls.DATE, CallLog.Calls.DURATION,
                        CallLog.Calls.NUMBER, CallLog.Calls._ID },
                CallLog.Calls.DATE + ">?",
                new String[] { String.valueOf(startDate.getTime())},
                CallLog.Calls.NUMBER + " asc");

            */

        int PhoneNumber=dataCursor.getColumnIndex(CallLog.Calls.NUMBER);
        int TypeofCall=dataCursor.getColumnIndex(CallLog.Calls.TYPE);
        //int DurationofCall=dataCursor.getColumnIndex(CallLog.Calls.DURATION);
        int dateofCall=dataCursor.getColumnIndex(CallLog.Calls.DATE);






        /*Traverse the Result Set */

        while(dataCursor.moveToNext()){
            //Log.d("Running","In while loop");
            String pNumber=dataCursor.getString(PhoneNumber);
            String typeNumber=dataCursor.getString(TypeofCall);
            int tnumber=Integer.parseInt(typeNumber);

            String dateString=dataCursor.getString(dateofCall);
            Date dateobject= new Date(Long.valueOf(dateString));

            Log.d("Date: ",dateobject.toString());
            //String durationNumber=dataCursor.getString(DurationofCall);


            if(dateobject.after(startDate)){
                Log.d("Running","In IF CONDITIOn");
                if(tnumber==CallLog.Calls.MISSED_TYPE){
                    missedCallsCount+=1;
                }
                else if(tnumber==CallLog.Calls.OUTGOING_TYPE){
                    OutgoingCallCount+=1;
                }
                else if(tnumber==CallLog.Calls.INCOMING_TYPE){
                    IncomingCallsCount+=1;
                }
            }


        }

        dataCursor.close();



        return;
    }

}
