我在自定义对话框中创建了一个日期选择器，而不像通常人们那样在DatepickerDialog中创建。 问题是当我尝试限制过去的日期时，在运行时应用程序崩溃时，日志cat out i附加。我的代码[附件]可能会遗漏一些内容，请帮忙。

答案 0 :(得分：0)
抱歉，对于错误编程，无法在init中调用view.UpdateDate（）（匿名内部类类型..） 这就是为什么崩溃在那里，虽然当DatePickerDialog对象被这样采用时，同样的逻辑是适用的：
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated
.................................
.................................
same logic as above code works for this scenario.
But i had used a Custom Dialog to increase UI Flexibility, so here's the perfect solution:
1. 1st get the Time in Millis for the Past Date[Called Min Date to be set in Date Picker]
2. If it is Current Date then do not use current time System.getCurrentTimeinMillis(); as it's always greater than the Actual date's Initial Time so using this will crash DatePicker. Instead send this current date to a date to time converter function as i had mentioned below:
public void getCurrDate()
{
Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
return ""+(month+1)+"/"+day+"/"+year;
}
String input = getCurrDate();
Date date;
try {
date = new SimpleDateFormat("MM/dd/yyyy", Locale.ENGLISH).parse(input);
long milliseconds = date.getTime();
if(milliseconds>0){
datePicker.setMinDate(milliseconds);
//This Function will work fine, to set a future constraint use setMaxDate(long time);
}
else
{
//whatever else cond...
}
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
