英文:
Wrong datPicker format in editText
问题
我有一个日期选择器（datePicker），我想在从中获取日期时在编辑框（editText）中显示它，但格式不对。
例如，我选择了 1 月 01 日 2020 年。
但在编辑框内显示的是 2020/0/1 而不是 2020/01/01。
打开日期选择器：
new SpinnerDatePickerDialogBuilder()
.context(AddProjectActivity.this)
.callback(AddProjectActivity.this)
.spinnerTheme(R.style.NumberPickerStyle)
.showTitle(true)
.showDaySpinner(true)
.defaultDate(2017, 0, 1)
.maxDate(2100, 0, 1)
.minDate(2020, 0, 1)
.build()
.show();
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
meEdtDate.setText(year + "/" + (monthOfYear + 1) + "/" + dayOfMonth);
date = getDate(year, monthOfYear, dayOfMonth);
}
private Date getDate(int year, int monthOfYear, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(year, monthOfYear, dayOfMonth);
return calendar.getTime();
}
将日期设置到编辑框中：
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
String dateStr = simpleDateFormat.format(projectEntity.getDate());
meEdtDate.setText(dateStr);
英文:
I have a datePicker that I want to display in the editText when I take the date from it, it has the wrong format.
For example, I
Jan / 01/2020
I choose.
But inside text editing
It shows 2020/0/1 instead of 2020/01/01
open datePicker:
new SpinnerDatePickerDialogBuilder()
.context(AddProjectActivity.this)
.callback(AddProjectActivity.this)
.spinnerTheme(R.style.NumberPickerStyle)
.showTitle(true)
.showDaySpinner(true)
.defaultDate(2017, 0, 1)
.maxDate(2100, 0, 1)
.minDate(2020, 0, 1)
.build()
.show();
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
meEdtDate.setText(year + "/" + monthOfYear + "/" + dayOfMonth);
date = getDate(year, monthOfYear, dayOfMonth);
}
private Date getDate(int year, int monthOfYear, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(year, monthOfYear, dayOfMonth);
return calendar.getTime();
}
set date to editText:
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
String dateStr = simpleDateFormat.format(projectEntity.getDate());
meEdtDate.setText(dateStr);

这是使用当前包java.time中的类来处理日期的解决方案。
您可以像这样根据年份、月份和日期创建一个LocalDate：
private static LocalDate getDate(int year, int monthOfYear, int dayOfMonth) {
return LocalDate.of(year, monthOfYear, dayOfMonth);
}
然后可以将其格式化为字符串，就像这样：
LocalDate date = getDate(2020, 1, 1);
String dateString = date.format(DateTimeFormatter.ofPattern("yyyy/MM/dd"));
英文:
Here is a solution using classes from the current package, java.time, for date handling.
You can create a LocalDate from year, month and day like this
private static LocalDate getDate(int year, int monthOfYear, int dayOfMonth) {
return LocalDate.of(year, monthOfYear, dayOfMonth);
}
And then format it into a String like this
LocalDate date = getDate(2020, 1, 1);
String dateString = date.format(DateTimeFormatter.ofPattern("yyyy/MM/dd"));
