如何设置最大日期在数据采集器对话框在安卓？

在我的应用程序使用日期选择器设置日期。我想设置日期选择器的最大日期为今天的日期根据系统的日期。我不知道如何设置日期选择器的最大日期为今天的日期。谁能帮我解决这个问题。

我的约会选择代码是:

private int pYear;
private int pMonth;
private int pDay;
static final int DATE_DIALOG_ID = 0;


final Calendar c = Calendar.getInstance();
pYear = c.get(Calendar.YEAR);
pMonth = c.get(Calendar.MONTH);
pDay = c.get(Calendar.DAY_OF_MONTH);


// Date picker
public Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:


DatePickerDialog.OnDateSetListener pDateSetListener = new DatePickerDialog.OnDateSetListener() {


public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {


pYear = year;
pMonth = monthOfYear;
pDay = dayOfMonth;


e_dob.setText(new StringBuilder()
// to set date in editext
.append(pDay).append("/").append(pMonth + 1)
.append("/").append(pYear).append(" "));
}
};
return new DatePickerDialog(this, pDateSetListener, pYear, pMonth,
pDay);


}
return null;
}

break;
}
}
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// write your code here to get the selected Date
}
};

试试这个，应该可以，谢谢

您可以尝试替换这一行:

return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);

通过这些:

DatePickerDialog dpDialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
DatePicker datePicker = dpDialog.getDatePicker();


Calendar calendar = Calendar.getInstance();//get the current day
datePicker.setMaxDate(calendar.getTimeInMillis());//set the current day as the max date
return dpDialog;
小开
最佳答案

使用 setMaxDate()。

例如，将 return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay)语句替换为以下内容:

    DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
dialog.getDatePicker().setMaxDate(new Date().getTime());
return dialog;
小开

获取今天的日期(和时间) ，并应用他们作为最大日期。

Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Mounth -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());

我们也可以这样做(检查这个 堆栈溢出答案中的 System.currentTimeMillis () vs Calendar 方法)

long now = System.currentTimeMillis() - 1000;
dp_time.setMinDate(now);
dp_time.setMaxDate(now+(1000*60*60*24*7)); //After 7 Days from Now
小开

您可以创建 自定义日期选择器，这是所有 api 级别的工作。

public class CustomDatePickerDialog extends DatePickerDialog {


int maxYear;
int maxMonth;
int maxDay;


public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
super(context, callBack, year, monthOfYear, dayOfMonth);
}


public void setMaxDate(long maxDate) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
getDatePicker().setMaxDate(System.currentTimeMillis());
} else {
final Calendar c = Calendar.getInstance();
c.setTimeInMillis(maxDate);
maxYear = c.get(Calendar.YEAR);
maxMonth = c.get(Calendar.MONTH);
maxDay = c.get(Calendar.DAY_OF_MONTH);
}
}


@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
super.onDateChanged(view, year, monthOfYear, dayOfMonth);
} else {
if (year > maxYear)
view.updateDate(maxYear, maxMonth, maxDay);


if (monthOfYear > maxMonth && year == maxYear)
view.updateDate(maxYear, maxMonth, maxDay);


if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
view.updateDate(maxYear, maxMonth, maxDay);
}
}

设定最大日期

final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(getActivity(),
myDateListener, year, month, day);
pickerDialog.setMaxDate(System.currentTimeMillis());
pickerDialog.show();
小开

我通过跟踪解决了这个问题

final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
datePickerDialog = new DatePickerDialog(getActivity(), this, year, month, day);
datePickerDialog.getDatePicker().setMinDate(c.getTimeInMillis());

希望能对你有所帮助

用法

将 EightFoldsDatePickerDialog.java 复制到项目中

EightFoldsDatePickerDialog datePickerDialog=new EightFoldsDatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
//Do something with date
Toast.makeText(this, "Year "+year+" month "+month+" day "+dayOfMonth, Toast.LENGTH_SHORT).show();
}
},year,month,day);   // give any  year , month , day values, this will be opened by default in dialog


datePickerDialog.setMinDate(2017,8,7); //arguments are   year , month , date (use for setting custom min date)
datePickerDialog.setMaxDate(2017,8,25);  //arguments are   year , month , date (use for setting custom max date)


// datePickerDialog.setTodayAsMinDate();   // sets today's date as min date
// datePickerDialog.setTodayAsMaxDate();    // sets today's date as max date


datePickerDialog.show();

结果

试试这个

我已经尝试了太多的解决方案，但是没有一个是有效的，在浪费了我的半天之后，我终于找到了一个解决方案。

这段代码只是向您显示一个 DatePickerDialog，其中包含最小和最大日期、月份和年份，只需修改即可。

final Calendar calendar = Calendar.getInstance();
DatePickerDialog dialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker arg0, int year, int month, int day_of_month) {
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, (month+1));
calendar.set(Calendar.DAY_OF_MONTH, day_of_month);
String myFormat = "dd/MM/yyyy";
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());
your_edittext.setText(sdf.format(calendar.getTime()));
}
},calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());// TODO: used to hide previous date,month and year
calendar.add(Calendar.YEAR, 0);
dialog.getDatePicker().setMaxDate(calendar.getTimeInMillis());// TODO: used to hide future date,month and year
dialog.show();

禁用以前和将来的日历

下面是一个 Kotlin 扩展函数:

fun EditText.transformIntoDatePicker(context: Context, format: String, maxDate: Date? = null) {
isFocusableInTouchMode = false
isClickable = true
isFocusable = false


val myCalendar = Calendar.getInstance()
val datePickerOnDataSetListener =
DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
myCalendar.set(Calendar.YEAR, year)
myCalendar.set(Calendar.MONTH, monthOfYear)
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
val sdf = SimpleDateFormat(format, Locale.UK)
setText(sdf.format(myCalendar.time))
}


setOnClickListener {
DatePickerDialog(
context, datePickerOnDataSetListener, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)
).run {
maxDate?.time?.also { datePicker.maxDate = it }
show()
}
}
}

用法:

活动内容:

editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())

片段:

editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())
