Question

我的应用中有DatePicker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：

 @Override
public 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。感谢。

Answer 1

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);
    }
};

//当您调用showDialog()方法

时，方法会自动被调用

   @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）;

Answer 2

试试这个：

// set date picker with current date
DatePickerDialog date = new DatePickerDialog(this, datePickerListener, mYear,mMonth,mDay){
            // Comapre the date selected in picker with the current date.      
            @Override
            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
            {   
                if (year < mYear)
                    view.updateDate(mYear,mMonth,mDay);

                if (monthOfYear < mMonth && year == mYear)
                    view.updateDate(mYear,mMonth,mDay);

                if (dayOfMonth < mDay && year == mYear && monthOfYear == mMonth)
                    view.updateDate(mYear,mMonth,mDay);

            }
        };
        return date;
    }        

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {

    // as soon as the dialog box is closed, this method will be called.
    public void onDateSet(DatePicker view, int selectedYear,
            int selectedMonth, int selectedDay) {
        mYear = selectedYear;
        mMonth = selectedMonth;
        mDay = selectedDay;

        // set selected date into textview
        txtDate.setText(new StringBuilder().append(mMonth + 1)
                .append("-").append(mDay).append("-").append(mYear)
                .append(" "));    

    }
};

Answer 3

只需尝试此解决方案：

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

Answer 4

我认为您实际上无法禁用日期选择器。但是一旦选择了日期，您就可以使用当前日期对其进行验证，并让用户重新选择将来的日期。如果用户选择过去的日期，您可以发送Toast消息。

Answer 5

在你的onDateSet中你可以在日期验证，就像你想在今天的日期之后设置日期一样，然后在onDateSet方法中添加以下代码

            Calendar cl = Calendar.getInstance();
            cl.set(year, monthOfYear, dayOfMonth);
            if (cl.after(Calendar.getInstance())) { 
                    //set your date
            }else{
                    //do nothing
            }

希望这对你有用

Answer 7

我已经设置了一个名为startbtn和listener的按钮，以便每当用户单击该按钮时，它将提示一个日期选择器对话框，并将日期设置为一个名为startet的TextView

//getting calendar instance
    calendar = Calendar.getInstance();
    year = calendar.get(Calendar.YEAR);
    month = calendar.get(Calendar.MONTH);
    day = calendar.get(Calendar.DAY_OF_MONTH);

startbtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DatePickerDialog startDatePicker = new DatePickerDialog(Search.this, new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    startet.setText(dayOfMonth + "-" + (month + 1) + "-" + year);
                    startDay = dayOfMonth;
                    startMonth = month + 1;
                    startYear = year;
                }
            }, year, month, day);
            //Disable date before today
            startDatePicker.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
            startDatePicker.show();
        }
    });
