How to restrict date picker from accepting current and future dates in android i am using google api...any idea..?

推荐答案

1. 从 API 级别 11 开始，就有了一种方法:

1. Since API level 11 there is a method for that:

DatePicker.setMaxDate(long maxDate)

如果它必须在以前的版本中工作，请使用此方法:

If it has to work in previous versions, use this method:

public void init(int year, int monthOfYear, int dayOfMonth, DatePicker.OnDateChangedListener onDateChangedListener)

您可以传递您自己的 OnDateChangedListener，它将无效日期重置"为最新的有效日期:

You could pass your own OnDateChangedListener which "resets" invalid dates to the newest valid one:

DatePicker picker = ...
int year = ...
int monthOfYear = ...
int dayOfMonth = ...
picker.init(year, monthOfYear, dayOfMonth, new DatePicker.OnDateChangedListener() {

    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        // check if current date is OK
        boolean dateOk = ...
        if (!dateOk) {
            // correct the date, but be sure the corrected date is OK
            // => otherwise you might get endless recursion
            year = ...
            monthOfYear = ...
            dayOfMonth = ...
            // update the date widget with the corrected date values
            view.updateDate(year, monthOfYear, dayOfMonth);
        }
    }
});
