Question

我的应用程序中有两个SeekBar。一个显示小时，另一个显示间隔为15分钟（0,15,30,45）。

我的初始值设置为10.30。我在TextView中显示更改的时间。

现在，如果用户仅增加分钟搜索栏（例如15分钟），则textView应显示10.45。（即10.30 + 00:15）。同样，如果用户进一步将分钟搜索栏增加到30或45，则TextView应分别显示11:00和11:15。

目前，一切正常，直到分钟达到15分钟。但是当我将SeekBar增加到30或45时，TextView会显示10:60和10:75。

这是我的代码： -

int hourLimit=10, minLimit=30;
    seekBarHour.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
    {


        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
        {


        }



        public void onStartTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub
        }

        public void onStopTrackingTouch(SeekBar seekBar) 
        {
            if(progressChangedHours == 0 && progressChangedMins==0)
            {
                txtReachingBy.setText("Reaching by:"+" "+String.valueOf(hourLimit)+":"+String.valueOf(minLimit)+":"+today.second);
            }
            if(progressChangedHours==0 && mins >=60)
            {
                hour = 1;
            }
            else
            {
            hour = hourLimit + progressChangedHours;

            }
            timeString = String.valueOf(hour)+":"+String.valueOf(mins)+":"+today.second;
            txtReachingBy.setText("Reaching by:"+" "+timeString);
        }





    }); 

    seekBarMins.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
    {


        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
        {
            progressChangedMins = progress;
            int stepSize = 15;

            progressChangedMins = (progressChangedMins/stepSize)*stepSize;

        }



        public void onStartTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub
        }

        public void onStopTrackingTouch(SeekBar seekBar) 
        {

            if(progressChangedMins == 0)
            {
                txtReachingBy.setText("Reaching by:"+" "+String.valueOf(hourLimit)+":"+String.valueOf(30)+":"+today.second);
            }
            else
            {


                mins = minLimit +progressChangedMins;
                if(progressChangedHours==0 && mins!=0)
                {
                    hour = hourLimit;
                }
                else if(progressChangedHours>=0 && mins>=60)
                {
                    hour = hour+1;
                    mins = mins-60;
                }


                timeString = String.valueOf(hour)+":"+String.valueOf(mins)+":"+today.second;
                txtReachingBy.setText("Reaching by:"+" "+timeString);
            }
        }



    });

修改

：我使用Date来解决我的问题的一部分： -

    DateFormat sdf = new SimpleDateFormat("hh:mm:ss");
        Date date;
        try 
        {
            date = sdf.parse(initialTime);
            cal= Calendar.getInstance();
            cal.setTime(date);

            txtReachingBy.setText("Reaching By:"+" "+ cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE));
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

seekBarMins.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
        {


            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
            {
                progressChangedMins = progress;
                int stepSize = 15;

                progressChangedMins = (progressChangedMins/stepSize)*stepSize;
                seekBar.setProgress(progressChangedMins);
                if(progressChangedHours ==0 && progressChangedMins!=0)
                {
                    lblLateBy.setText("Late By (Hrs):"+" " + String.valueOf(progressChangedHours) +":"+String.valueOf(progressChangedMins));
                }

                else
                lblLateBy.setText("Late By (Hrs):"+" " + String.valueOf(progressChangedHours) +":"+String.valueOf(progressChangedMins));



            }



            public void onStartTrackingTouch(SeekBar seekBar) {
                // TODO Auto-generated method stub
            }

            public void onStopTrackingTouch(SeekBar seekBar) 
            {

                if(progressChangedMins==0)
                {
                    timeString = cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE)+":"+today.second;
                }
                else
                {
                cal.add(Calendar.MINUTE, progressChangedMins);

                timeString = cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE)+":"+today.second;
                }
                txtReachingBy.setText("Reaching by:"+" "+timeString);

            }



        });

如果我将搜索栏拇指一次拖动到一个值，现在一切正常。进度值将添加到初始时间。但是如果我将它拖动到一个值，初始时间随着加法而改变，那么如果我再拖动它，则进度值将被添加到新时间而不是初始值。

给我输出为： -

Drag 1-> 15 mins > Time expected 10.45 (Fine)
Drag 2-> 30 mins > Time expected 11.00 Output I get -> 10.45+00.30 = 11.15

我该如何解决这个问题？

如果分钟超过60 android，则增加小时
