Android DatePicker：根据CURRENT日期禁用PREVIOUS日期

概述我的应用程序中有一个DatePicker,它以这种方式设置：布局：<TextViewandroid:id="@+idraveltext"android:layout_width="wrap_content"android:layout_height="wrap_content"

我的应用程序中有一个DatePicker,它以这种方式设置：

布局：

            <TextVIEw                androID:ID="@+ID/traveltext"                androID:layout_wIDth="wrap_content"                androID:layout_height="wrap_content"                androID:layout_weight="1.11"                androID:text="Date Of Travel"                androID:textStyle="bold" />             <EditText            androID:ID="@+ID/txtDate"            androID:layout_wIDth="wrap_content"            androID:layout_height="wrap_content"            androID:layout_weight="1" >        </EditText>              <button            androID:ID="@+ID/btnCalendar"            androID:layout_wIDth="30dp"            androID:layout_height="42dp"            androID:layout_marginRight="50dp"            androID:background="@drawable/date" >        </button>        </linearLayout>

全球价值观：

button btnCalendar;EditText txtDate;private int mYear, mMonth, mDay;

OnCreate：

btnCalendar = (button) findVIEwByID(R.ID.btnCalendar);    txtDate = (EditText) findVIEwByID(R.ID.txtDate);    btnCalendar.setonClickListener(this);

方法 ：

 @OverrIDepublic voID onClick(VIEw v) {    if (v == btnCalendar) {        // Process to get Current Date        final Calendar c = Calendar.getInstance();        mYear = c.get(Calendar.YEAR);        mMonth = c.get(Calendar.MONTH);        mDay = c.get(Calendar.DAY_OF_MONTH);        // Launch Date Picker Dialog        DatePickerDialog dpd = new DatePickerDialog(this,                new DatePickerDialog.OnDateSetListener() {                    @OverrIDe                    public voID onDateSet(DatePicker vIEw, int year,                            int monthOfYear, int dayOfMonth) {                        // display Selected date in textBox                        txtDate.setText(dayOfMonth + "-"                                + (monthOfYear + 1) + "-" + year);                    }                }, mYear, mMonth, mDay);        dpd.show();    }   }

现在我的问题是,如何根据CURRENT日期禁用PREVIoUS日期？

请帮忙.谢谢.

解决方法:

private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {    // the callback received when the user "sets" the Date in the    // DatePickerDialog    public voID onDateSet(DatePicker vIEw, int yearSelected,            int monthOfYear, int dayOfMonth) {        year = yearSelected;        month = monthOfYear + 1;        day = dayOfMonth;        // Set the Selected Date in Select date button        txtarrivedate.setText(year + "-" + month + "-" + day);    }};

//当调用showDialog()方法时,方法会自动调用

   @OverrIDe   protected Dialog onCreateDialog(int ID) {    switch (ID) {    case 1:        // create a new DatePickerDialog with values you want to show        DatePickerDialog da = new DatePickerDialog(this, mDateSetListener,                mYear, mMonth, mDay);        Calendar c = Calendar.getInstance();        c.add(Calendar.DATE, 1);        Date newDate = c.getTime();        da.getDatePicker().setMinDate(newDate.getTime());        return da;        // create a new TimePickerDialog with values you want to show    case 2:        // create a new DatePickerDialog with values you want to show        DatePickerDialog da1 = new DatePickerDialog(this,                mDateSetListener2, mYear, mMonth, mDay);        Calendar c1 = Calendar.getInstance();        c1.add(Calendar.DATE, 1);        Date newDate2 = c1.getTime();        da1.getDatePicker().setMinDate(newDate2.getTime());        return da1;    }    return null;}

仅使用用于调用对话框
的ShowDialog(1);
