Я хочу ограничить выбор даты, чтобы установить дату, указанную выше текущей системы. скажите мне, как проверить дату datepicker.Как ограничить дату текстового поля datepicker на будущую дату. он должен разрешить только предыдущую дату.
Create Custom Dialog an show toat on date greater then current date
final Dialog dialog = new Dialog(SettingActivity.this);
dialog.setContentView(R.layout.date_picker_view);
dialog.setTitle("Select Date");
final TextView tvTime = (TextView) dialog
.findViewById(R.id.tv_time);
final DatePicker datePicker = (DatePicker) dialog
.findViewById`enter code here`(R.id.datePicker1);
Button set = (Button) dialog.findViewById(R.id.button_time_set);
Button cancel = (Button) dialog
.findViewById(R.id.button_time_cancel);
datePicker
.setDescendantFocusability(DatePicker.FOCUS_BLOCK_DESCENDANTS);
Calendar originalDate=Calendar.getInstance();
Calendar previousWeekDay = (Calendar) originalDate.clone();
previousWeekDay.add(Calendar.YEAR, -35);
previousWeekDay.set(Calendar.MONTH, 0);
previousWeekDay.set(Calendar.DAY_OF_MONTH, 1);
datePicker.init(previousWeekDay.get(Calendar.YEAR), previousWeekDay.get(Calendar.MONTH), previousWeekDay.get(Calendar.DAY_OF_MONTH), null);
final Calendar calendar = Calendar.getInstance();
final int mDay = calendar
.get(Calendar.DAY_OF_MONTH)+1;
calendar.set(Calendar.DAY_OF_MONTH, mDay);
set.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
Calendar cal=Calendar.getInstance();
cal.set(datePicker.getYear(), datePicker.getMonth(), datePicker.getDayOfMonth());
if(cal.after(calendar)){
Toast.makeText(SettingActivity.this, "DOB not more then current date", Toast.LENGTH_SHORT).show();
handler.etDOB.setText("");
}else{
date_selected = String.valueOf(datePicker.getDayOfMonth())+"/"+String.valueOf(datePicker.getMonth()+1)+"/"+String.valueOf(datePicker.getYear());
handler.etDOB.setText(datePicker.getDayOfMonth()+"-"+AccessRecordForPDF.MONTHS[datePicker.getMonth()+1]+"-"+String.valueOf(datePicker.getYear()));
dialog.dismiss();
}
}
});
cancel.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
dialog.show();
}
});
And create dialog.xml

Поскольку уровень API 11 существует способ для этого:
1.DatePicker.setMaxDate (длинный MaxDate)
2.Если он должен работать в предыдущих версиях, использование этот метод:
