如何在没有日期选择器控制的情况下在android窗体中设置出生日期

Question

我正在做一个项目，该项目有一个注册表单，其中有一个出生日期字段。所以我尝试使用日期选择器控件。但很难在控件中设置最大和最小日期。此外，蜂窝之前的版本与蜂窝之后的版本也不同。以下是我使用的代码。

                    .append(" "));
           }
        };
}

蜂窝之前版本的自定义类：

package com.example.datepickercustom;
import android.app.DatePickerDialog;
import android.content.Context;
import android.widget.DatePicker;
public class DatePickerDialogWithMaxMinRange extends DatePickerDialog {
     static int maxYear=2005; 
     static int maxMonth=11;
     static int maxDay=31;
     int minYear=1955;
     int minMonth=0;
     int minDay=1;

    public DatePickerDialogWithMaxMinRange(Context context,  OnDateSetListener callBack,int minYear,int minMonth,int minDay,int maxYear,int maxMonth,int maxDay) {
        super(context,callBack, maxYear, maxMonth, maxDay);
        this.minDay = minDay;
        this.minMonth = minMonth;
        this.minYear = minYear;
        DatePickerDialogWithMaxMinRange.maxDay = maxDay;
        DatePickerDialogWithMaxMinRange.maxMonth = maxMonth;
        DatePickerDialogWithMaxMinRange.maxYear = maxYear;
    }
    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        super.onDateChanged(view, year, monthOfYear, dayOfMonth);
            if (year > maxYear ||monthOfYear > maxMonth && year == maxYear||
                     dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth){
                view.updateDate(maxYear, maxMonth, maxDay);
                }else if(year < minYear ||monthOfYear < minMonth && year == minYear||
                     dayOfMonth < minDay && year == minYear && monthOfYear == minMonth){
                 view.updateDate(minYear, minMonth, minDay );
                }
    }
}

我的问题是，上面的内容似乎很长，很难设定出生日期。有比这更好的方法吗？

Answer 1

DatePicker具有setMinDate和setMaxDate方法。用它们设置最短和最长日期非常容易。

你在这下面是什么意思？：

蜂窝工作之前的版本与蜂窝工作之后的版本不同蜂窝

当然有区别。DatePicker与当前的安卓版本匹配，对于任何控件，都应该有的差异。

您可以使用第三方库来显示日历视图，然后单击即可选择所需日期。我也使用了时间广场的利布，目的相同，非常好。看看这里。还有另一个很好的库检查THIS
在对话框中使用它们，并在完成日期选择后取消对话框。如前所述，您还可以在所需的任何日期范围内显示视图。所以你可以设置一个最长和最短日期。只需正确阅读用法及其简单有效的
