最近在开发的过程中使用到了TimePicker,需求是可选择24小时制的时间日期,然后发现设置setIs24HourView(true)之后,再使用TimePicker的getCurrentHour得到的却是12小时制,也就是下午的时间,比如14点会显示为2点,那到底是什么原因呢?
小编在实现的过程中代码如下:
/**
* 日期选择器弹窗
* @param activity
* @param textView
*/
public static void showDatePickerDialog(Activity activity, final TextView textView) {
Calendar calendar = Calendar.getInstance();
new TimePickerDialog(activity, TimePickerDialog.THEME_HOLO_LIGHT, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mHour = String.valueOf(hourOfDay);
mMinute = String.valueOf(minute);
if(hourOfDay < 10){
mHour = "0" + hourOfDay;
}
if(minute < 10){
mMinute = "0" + minute;
}
textView.setText(mYear + "-" + mMonth + "-" + mDay +" "+ mHour + ":" + mMinute + ":00");
}
}
,calendar.get(Calendar.HOUR)
,calendar.get(Calendar.MINUTE),true).show();
new DatePickerDialog(activity, DatePickerDialog.THEME_HOLO_LIGHT,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
mYear = String.valueOf(year);
mMonth = String.valueOf(monthOfYear + 1);
mDay = String.valueOf(dayOfMonth);
if (monthOfYear < 9) {
mMonth = "0" + mMonth;
}
if (dayOfMonth < 10) {
mDay = "0" + mDay;
}
}
}
// 设置初始日期
,calendar.get(Calendar.YEAR)
,calendar.get(Calendar.MONTH)
,calendar.get(Calendar.DAY_OF_MONTH)).show();
}
最后各方查阅终于得到答案,其实就是日期格式类型的问题:
代码中:
calendar.get(Calendar.HOUR)
修改为下面这两种方式实现都可以:
calendar.get(Calendar.HOUR_OF_DAY)
或
calendar.get(Calendar.getInstance().HOUR_OF_DAY)
当然,可能有些需求代码并不是这样实现的,但问题是一样的,比如下面这种:
TimePicker picker = (TimePicker) findViewById(R.id.timePicker1);
picker.setIs24HourView(true);
Calendar calendar = Calendar.getInstance();
picker.setCurrentHour(calendar.get(calendar.HOUR_OF_DAY));
这样问题就完美解决了!
希望可以帮助到开发中遇到此问题的,喜欢的可以点个关注哦,谢谢!
