以 hh:mm 格式显示时间选择器

Question

我必须在单击编辑 text.So 时以 hh:mm 格式显示时间选择器，我使用了以下代码。

MainActivity.java:

  e6.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                    // TODO Auto-generated method stub
                    SimpleDateFormat sdf = new SimpleDateFormat("hh:mm");
                    Calendar mcurrentTime = Calendar.getInstance();
                    int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
                    int minute = mcurrentTime.get(Calendar.MINUTE);
                    TimePickerDialog mTimePicker;
                    mTimePicker = new TimePickerDialog(AddFlight.this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                            e6.setText(selectedHour + ":" + selectedMinute);

                        }
                    }, hour, minute, true);//Yes 24 hour time
                    mTimePicker.setTitle("Select Time");
                    mTimePicker.show();

            }
        });

它运行良好并显示时间 picker.But 我的问题是，当我在时间选择器中 select 04:15 时，它显示4:15。在4.I需要以hh:mm格式显示时间选择器之前不包括0。

任何人都可以帮助我 this.Thank 你。

Answer 1

你可以这样试试...

mTimePicker = new TimePickerDialog(AddFlight.this, new TimePickerDialog.OnTimeSetListener() {
    @Override
    public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
        String formattedTime = "";
        String sHour = "00";
        // converting hour to tow digit if its between 0 to 9. (e.g. 7 to 07)
        if(selectedHour < 10)
            sHour = "0"+selectedHour;
        else
            sHour = String.valueOf(selectedHour);


        e6.setText(sHour + ":" + selectedMinute);
    }
}, hour, minute, true);

Answer 2

刚才我提到了这个post并更改了单行：

这一行

e6.setText(selectedHour + ":" + selectedMinute);

至

e6.setText(String.format("%02d:%02d", selectedHour, selectedMinute));

Answer 3

就用这个方法，

private String getDD(int num) {
   return num > 9 ? "" + num : "0" + num;
}

Answer 4

只需将文本设置为“%02d:%02d”，如下所示：

e6.setText(String.format("%02d:%02d", selectedHour, selectedMinute));
