Android的日期选择器最低最高日期API级别11日前 [英] Android datepicker min max date before api level 11

问题描述

我想日期选取器在Android中的最小值和最大值设置日期之前API级11，我用下面的code：

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 = startDatePickerDialog.getClass().getDeclaredField("mDatePicker");
mDatePickerField.setAccessible(true);

DatePicker startDatePickerInstance =(DatePicker)mDatePickerField.get(startDatePickerDialog);
startDatePickerInstance.init(mYearMin, mMonthMin, mDayMin, new DatePicker.OnDateChangedListener() {
    @Override
    public void onDateChanged(DatePicker datePicker, int i, int i1, int i2) {
        Date maxDate = new Date(mYearMax, mMonthMax, mDayMax, 0, 0, 0);
        Date selectedDate = new Date(i, i1, i2, 0, 0, 0);
        if (selectedDate.after(maxDate)) {
            datePicker.updateDate(mYearMax, mMonthMax, mDayMax);                                        
        }
    }
}

不过， updateDate 方法火灾 onDateChanged 再次和日期选择器不会被更新。照片 任何人都可以帮助解决这个问题？

However, the updateDate method fires onDateChanged again and the date picker is not updated.
Can anyone help to solve the problem?

推荐答案

您可以设置范围的init日期选择器的方法。 例如与最小值：

You can set range with init datePicker method. Example with min value :

// Calendar
this.calendar = new GregorianCalendar();
this.datePicker = (DatePicker) findViewById(R.id.xxxxx);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    // (picker is a DatePicker)
    this.datePicker.setMinDate(this.calendar.getTimeInMillis());
} else {
    final int minYear = this.calendar.get(Calendar.YEAR);
    final int minMonth = this.calendar.get(Calendar.MONTH);
    final int minDay = this.calendar.get(Calendar.DAY_OF_MONTH);

    this.datePicker.init(minYear, minMonth, minDay,
            new OnDateChangedListener() {

                public void onDateChanged(DatePicker view, int year,
                        int month, int day) {
                    Calendar newDate = Calendar.getInstance();
                    newDate.set(year, month, day);

                    if (calendar.after(newDate)) {
                        view.init(minYear, minMonth, minDay, this);
                    }
                }
            });
    Log.w(TAG, "API Level < 11 so not restricting date range...");
}
