DatePicker datePicker = (DatePicker)findViewById(R.id.new_date_picker);

datePicker.init(year, month, day, new OnDateChangedListener() {  

@Override public void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) {  

if(isDateAfter(view)){  

Toast.makeText(MainActivity.this, "到职日期选择正确", 0).show();    

}else{ Toast.makeText(MainActivity.this, "到职日期应该在今天之后,请重新选择", 0).show();    
       } 

}

private boolean isDateAfter(DatePicker tempView) {  

Calendar mCalendar = Calendar.getInstance();  

Calendar tempCalendar = Calendar.getInstance();  

tempCalendar.set(tempView.getYear(), tempView.getMonth(), tempView.getDayOfMonth(), 0, 0, 0);  

if(tempCalendar.after(mCalendar))  

return true;
