我正在尝试按应用指定的时区设置日期选择器。我在应用当前选择和 minDates 方面取得了一定的成功，但我无法更改今天的日期(日期选择器对话框中的粗体数字)。我上传了一张图片，其中显示了日期选择器使用 getDefult 时区来设置今天的日期而不是指定的时区。
如何指定今天的日期？
billDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
billDateDialog.show();
billDateDialog.updateDate(billDateCal.get(Calendar.YEAR), billDateCal.get(Calendar.MONTH), billDateCal.get(Calendar.DAY_OF_MONTH));
}
});
billDateDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
long correctedTime = new DayLightSavings(BillsAdd.this, year, monthOfYear, dayOfMonth, timeZone).getCorrectedTime();
billDateCal.setTimeInMillis(correctedTime);
billDate.setText(dateFormatter.format(billDateCal.getTimeInMillis()));
}
},billDateCal.get(Calendar.YEAR), billDateCal.get(Calendar.MONTH), billDateCal.get(Calendar.DAY_OF_MONTH));
long oneDay = TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS);
long oldRawOffset = TimeZone.getDefault().getRawOffset();
long newRawOffset = timeZone.getRawOffset();
long rawOffset = oldRawOffset - newRawOffset;
billDateDialog.getDatePicker().setMinDate(Calendar.getInstance().getTimeInMillis() + oneDay - rawOffset);
最佳答案
您可以查看此代码。这可能对您有所帮助...
//Create calendar instance
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
// Launch Date Picker Dialog
final DatePickerDialog dpd = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
// Display Selected date in textbox
tvStartdate.setText(dayOfMonth + "-"
+ (monthOfYear + 1) + "-" + year);
tvStartdate.setTextColor(Color.BLACK);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String formatedDate = sdf.format(new Date(year - 1900, monthOfYear, dayOfMonth));
sd = formatedDate;
}
}, year, month, day);
dpd.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
dpd.show();
