当前尝试从时间选择器reminderHour 中获取两个不同的值，即selectedHour 和remindMin，即selectedMin。以为我让它工作得很好，但今天早上发现了另一个错误。

eReminderTime.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Calendar mcurrentTime = Calendar.getInstance();
                int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
                int minute = mcurrentTime.get(Calendar.MINUTE);
                TimePickerDialog mTimePicker;
                mTimePicker = new TimePickerDialog(AddPayment.this, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {



                        reminderHour = selectedHour;
                        reminderMin = selectedMinute;


                        if (selectedHour < 10)
                        {
                            if(selectedMinute == 0)
                            {
                                eReminderTime.setText("0" + selectedHour + ":00" + selectedMinute);
                            }
                            else if(selectedMinute < 10)
                            {
                                eReminderTime.setText("0" + selectedHour + ":0" + selectedMinute);
                            }
                            else
                            {
                                eReminderTime.setText("0" + selectedHour + ":" + selectedMinute);
                            }
                        }

                        if (selectedHour == 0)
                        {
                            if(selectedMinute == 0)
                            {
                                eReminderTime.setText("0" + selectedHour + ":00" + selectedMinute);
                            }
                            else if(selectedMinute < 10)
                            {
                                eReminderTime.setText("0" + selectedHour + ":0" + selectedMinute);
                            }
                            else
                            {
                                eReminderTime.setText("0" + selectedHour + ":" + selectedMinute);
                            }
                        }

                        if(selectedMinute == 0)
                        {
                            eReminderTime.setText("" + selectedHour + ":00" + selectedMinute);
                        }
                        if(selectedMinute < 10)
                        {
                            eReminderTime.setText("" + selectedHour + ":0" + selectedMinute);
                        }
                        else
                        {
                            eReminderTime.setText( "" + selectedHour + ":" + selectedMinute);
                        }


                    }
                }, hour, minute, true);

                mTimePicker.setTitle("Select Time");
                mTimePicker.show();

            }
        });

这是我的时间选择器的代码。我不希望时间加在一起，因为我需要将小时值与分钟值分开存储。

我尝试查找 SimpleDateFormat 但无法正常工作。这是我试过的代码

                    SimpleDateFormat simpleHour = new SimpleDateFormat("kk");
                    SimpleDateFormat simpleMin = new SimpleDateFormat("mm");

                    formatHour = simpleHour.format(selectedHour);
                    formatMin = simpleMin.format(selectedMinute);

                    reminderHour = Integer.parseInt(formatHour);
                    reminderMin = Integer.parseInt(formatMin);

                    Toast.makeText(getApplicationContext(), formatHour, 0).show();
                    Toast.makeText(getApplicationContext(), formatHour, 0).show();

你到底想要什么输出？如果只是这样：

01:32

然后很容易自己生成一个字符串，而不用担心日期格式等。

//Add leading zeros if required
String hours = (String) ((selectedHour < 10) ? "0" + selectedHour 
                                             : Integer.toString(selectedHour));
String minutes = (String) ((selectedMinute < 10) ? "0" + selectedMinute 
                                             : Integer.toString(selectedMinute));
String prettyTime = hours + ":" + minutes;

那是因为单独的hh和mm不是有效的格式。尝试将分钟和小时值组合在一起，当您收到组合值时，通过将它们分开split()

例如;

 SimpleDateFormat simpleHour= new SimpleDateFormat("hh:mm");
 String strTime = sdf.format(new Date());
 String[] pieces=strTime.split(":"); 
 Log.i("Hour: ",pieces[0]);
 Log.i("Miniute: ",pieces[1]);
