TimePickerDialog时间选择器，选择0-9分钟时，显示为10:0 9:1的样式，要改成 10:00 09:01的样式 的解决方式

    /**
     * 设置时间选择器
     */
    private void setTimePickerDialog() {
        Calendar mCalendar = Calendar.getInstance();
        mCalendar.setTimeInMillis(System.currentTimeMillis());
        final int hour = mCalendar.get(Calendar.HOUR_OF_DAY);
        int minute = mCalendar.get(Calendar.MINUTE);
        new TimePickerDialog(this,new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view,int hourOfDay,int minute)
            {
                //使用三元运算符来满足需求
                String sHour = hour < 10 ? "0" + hour : "" + hour;
                String sMinutes = minute < 10 ? "0" + minute : ""
                        + minute;
                //指定一个textview来显示时间
                textview.setText(sHour + ":" + sMinutes);
            }
        }, hour, minute, true).show();
    }
