Android的我怎麼能禁止過去的日期中的DatePicker

Question

我在Android的新的，請幫幫我，我該怎麼禁用過去的日期選擇日期，我不知道如何執行這個東西，

Answer 1

你可以做

datePicker.setMinDate(System.currentTimeMillis() - 1000); 

將今天的日期設置爲最短日期和所有過去的日期都被禁用。

日期選擇是的DatePicker的對象，如果你正在使用DatePickerDialog的對象，你可以做

datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000); 

Answer 2

我使用這個類日期選擇器。有了這個，你可以設定最低和最高日

public class Datepicker extends DialogFragment 
    implements DatePickerDialog.OnDateSetListener { 
TextView textView; 
Context context; 
private Boolean isMinDate; 
private DatePickerDialog datepic; 

public Datepicker() { 
} 

public Datepicker(TextView textView, Context context, Boolean isMinDate) { 
    this.context = context; 
    this.textView = textView; 
    this.isMinDate = isMinDate; 
} 

public Datepicker(TextView textView, Context context) { 
    this.context = context; 
    this.textView = textView; 

} 

@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    // Use the current date as the default date in the picker 
    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); 
    datepic = new DatePickerDialog(getActivity(), this, year, month, day); 
    datepic.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    if (isMinDate != null) { 
     if (isMinDate) { 
      setMinimumDate(c); 
     } else { 
      setMaximumDate(c); 
     } 
    } 
    // Create a new instance of DatePickerDialog and return it 
    return datepic; 
} 

@Override 
public void onDateSet(android.widget.DatePicker view, int year, int monthOfYear, int dayOfMonth) { 

    int month = monthOfYear + 1; 
    textView.setText(year + "-" + month + "-" + dayOfMonth); 
} 

public void setMinimumDate(Calendar mintime) { 
    datepic.getDatePicker().setMinDate(mintime.getTimeInMillis()); 
} 

public void setMaximumDate(Calendar maxTime) { 
    datepic.getDatePicker().setMaxDate(new Date().getTime()); 
}
