Android DatePicker日期限制

Question

我在我的活动中使用DatePicket,

我想将用户选择的日期限制为今天的日期.

他们不应该选择比今天更大的日期.

谢谢.

Answer 1

是的,你可以非常轻松地完成这里的验证是例子:

if(dateObj1.before(dateObj2) || dateObj1.equals(dateObj2)){
//the program runs normally
}
else{
                new AlertDialog.Builder(PM_Edit.this)

                .setTitle("Wrong Data Input!")

                .setMessage("The end Date must be Before the start Date, please insert new Date values")

                .setNeutralButton("Ok",

                new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog,

                int which) {

                }

                }).show();
            }

DatePicker datePicker = (DatePicker)findViewById(R.id.new_date_picker);


datePicker.init(year, month, day, new OnDateChangedListener() {

    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) {

        if(isDateAfter(view)){
            Calendar mCalendar = Calendar.getInstance();
            view.init(mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH), this);
        }
    }


    private boolean isDateAfter(DatePicker tempView) {
        Calendar mCalendar = Calendar.getInstance();
        Calendar tempCalendar = Calendar.getInstance();
        tempCalendar.set(tempView.getYear(), tempView.getMonth(), tempView.getDayOfMonth(), 0, 0, 0);
        if(tempCalendar.after(mCalendar))
            return true;
        else 
            return false;
    }
});
