私のアプリケーションでは、日付ピッカーを使用して日付を設定しています。日付ピッカーの最大日付をシステムの日付に従って今日の日付に設定したいのですが、日付ピッカーの最大日付を今日の日付として設定する方法がわかりません。この問題を解決するために。
私の日付ピッカーのコーディングは:
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;
}
setMaxDate()
を使用します。
たとえば、return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay)
ステートメントを次のように置き換えます。
DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
dialog.getDatePicker().setMaxDate(new Date().getTime());
return dialog;
今日の日付(および時刻)を取得し、最大日付として適用します。
Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Mounth -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());
またWEはこれを行うことができます(これを確認してください Stackoverflow answer System.currentTimeMillis()対Calendarメソッド)
long now = System.currentTimeMillis() - 1000;
dp_time.setMinDate(now);
dp_time.setMaxDate(now+(1000*60*60*24*7)); //After 7 Days from Now
この行を置き換えてみてください:
return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
それらによって:
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;
私はあまりにも多くのソリューションを試しましたが、どちらも機能していませんでした。私の半日を無駄にした後、最終的にソリューションを作りました。
このコードは、最小および最大の日付、月、年、およびそれを変更するだけで、DatePickerDialogを表示します。
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();
出力:-前および将来のカレンダーを無効にする
private int pYear;
private int pMonth;
private int pDay;
static final int DATE_DIALOG_ID = 0;
/**inside oncreate */
final Calendar c = Calendar.getInstance();
pYear= c.get(Calendar.YEAR);
pMonth = c.get(Calendar.MONTH);
pDay = c.get(Calendar.DAY_OF_MONTH);
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,
mDateSetListener,
pYear, pMonth-1, pDay);
}
return null;
}
protected void onPrepareDialog(int id, Dialog dialog) {
switch (id) {
case DATE_DIALOG_ID:
((DatePickerDialog) dialog).updateDate(pYear, pMonth-1, pDay);
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
}
};
これを試してみてください。ありがとう
mainコードでこのコードを直接使用して、あなたに役立つことを願っています...

EightFoldsDatePickerDialog.Javaをプロジェクトにコピーします

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

私はこれを次のように解決しました
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());

カスタム日付ピッカー を作成できます。これはすべてのAPIレベルで機能します。
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);
}
}
最大日付を設定
final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(getActivity(),
myDateListener, year, month, day);
pickerDialog.setMaxDate(System.currentTimeMillis());
pickerDialog.show();
DatePicker dp = (DatePicker) findViewById(R.id.datePicker1);
dp.setMaxDate(new Date().getTime());
