Android datepicker min max date before api level 11

Question

I am trying to set the min and max date of the date picker in Android to before API level 11. I used the following code:

mDatePickerField = startDatePickerDi         


        

Answer 1

Edit your DatePicker.java adding the following 3 code excerpts.

Declare the variables used for limiting the minimum and maximum date.

// Variables for defining minimum date 
private int minimumDay;
private int minimumMonth;
private int minimumYear;

// Variables for defining maximum date 
private int maximumDay;
private int maximumMonth;
private int maximumYear;

After the constructors, your have to override onDateChanged method.

// Called every time the user changes DatePicker values
public void onDateChanged(DatePicker view, int year, int monthOfYear, 
        int dayOfMonth) {

    // Test if chosen date is before minimum date
    boolean beforeMinDate = false;
    boolean afterMaxDate = false;

    if(year < minimumYear){
        beforeMinDate = true;
    }
    else if(year == minimumYear){
        if(monthOfYear < minimumMonth){
            beforeMinDate = true;
        }
        else if(monthOfYear == minimumMonth){
            if(dayOfMonth < minimumDay){
                beforeMinDate = true;
            }
        }
    }

    // Test if chosen date is after maximum date
    if(!beforeMinDate){
        if(year > maxYear){
            afterMaxDate = true;
        }
        else if(year == maxYear){
            if(monthOfYear > maxMonth){
                afterMaxDate = true;
            }
            else if(monthOfYear == maxMonth){
                if(dayOfMonth > maxDay){
                    afterMaxDate = true;
                }
            }
        }
    }

    // If chosen date is before minimum date, update the date and internal
    // calendar to minimum date, else, check similarly fot the maximum
    // date, else, use the valid chosen date.
    if(beforeMinDate)
    {
        mCalendar.set(minimumYear, minimumMonth, minimumDay, 
                mCalendar.get(Calendar.HOUR_OF_DAY), 
                mCalendar.get(Calendar.MINUTE));
        updateDate(minimumYear, minimumMonth, minimumDay);
    }
    else if (afterMaxDate)
    {
        mCalendar.set(maximumYear, maximumMonth, maximumDay, 
                mCalendar.get(Calendar.HOUR_OF_DAY), 
                mCalendar.get(Calendar.MINUTE));
        updateDate(maximumYear, maximumMonth, maximumDay);
    }
    else
        mCalendar.set(year, monthOfYear, dayOfMonth, 
                mCalendar.get(Calendar.HOUR_OF_DAY), 
                mCalendar.get(Calendar.MINUTE));
}

And now, create setter methods for the minimum and maximum dates.

    // Method to define minimum permitted date for the picker.
    public void setMinimumDate(int minimumDay, int minimumMonth, 
            int minimumYear)
    {
        this.minimumDay = minimumDay;
        this.minimumMonth = minimumMonth;
        this.minimumYear = minimumYear;
    }

    //Method to define maximum permitted date for the picker.
    public void setMaximumDate(int maximumDay, int maximumMonth, 
            int maximumYear)
    {
        this.maximumDay = maximumDay;
        this.maximumMonth = maximumMonth;
        this.maximumYear = maximumYear;
    }

Second part, in the activity you call the DatePicker dialog, you need to set the minimum and maximum desired dates. The code below sets the current date as minimum and two years in the future as the maximum date.

    // Define current date as the minimum desired date
    Calendar c = Calendar.getInstance(); 
    int currentDay = c.get(Calendar.DAY_OF_MONTH);
    int currentMonth = c.get(Calendar.MONTH);
    int currentYear = c.get(Calendar.YEAR);
    inicioDateTimePicker.setMinimumDate(currentDay, currentMonth, 
            currentYear);

    // Define two years in the future as the maximum desired date
    Calendar c = Calendar.getInstance(); 
    int currentDay = c.get(Calendar.DAY_OF_MONTH);
    int currentMonth = c.get(Calendar.MONTH);
    int currentYear = c.get(Calendar.YEAR);
    inicioDateTimePicker.setMinimumDate(currentDay, currentMonth, 
            currentYear + 2);
