从android中的日期选择器和时间选择器投射和获取值

Casting and getting values from date picker and time picker in android

提问by Rahul Kalidindi

I have a DatePickerand a TimePickerin my app. Can anyone tell me how to get the values of the date and time that are selected??? What i mean to say is, for EditTextwe can declare as

我的应用程序中有一个DatePicker和一个TimePicker。谁能告诉我如何获取所选日期和时间的值？？？我的意思是，因为EditText我们可以声明为

final EditText name = (EditText) this.findViewById(R.id.nametext);

and we can cast the data of it by using name.getText().toString().

我们可以使用name.getText().toString().

So similarly how can we get the values of DatePicker and TimePicker to a String???

那么类似地，我们如何将 DatePicker 和 TimePicker 的值转换为字符串？？？

DatePicker has

日期选择器有

getYear() 
getMonth() 
getDayOfMonth()

to make a Date object from a DatePicker you'd do new Date(datePicker.getYear() - 1900, datePicker.getMonth(), datePicker.getDayOfMonth());

从 DatePicker 创建一个 Date 对象，你会这样做 new Date(datePicker.getYear() - 1900, datePicker.getMonth(), datePicker.getDayOfMonth());

Note that this constructor was deprecated in API level 1- please refer to andrescanavesi's answerfor a more appropriate way of creating a Date object.

请注意，此构造函数在 API 级别 1 中已弃用- 请参阅 andrescanavesi 的回答以获取更合适的创建 Date 对象的方法。

TimePicker has

时间选择器有

getCurrentHour()
getCurrentMinute()

I use this:

我用这个：

    /**
 * 
 * @param datePicker
 * @return a java.util.Date
 */
public static java.util.Date getDateFromDatePicket(DatePicker datePicker){
    int day = datePicker.getDayOfMonth();
    int month = datePicker.getMonth();
    int year =  datePicker.getYear();

    Calendar calendar = Calendar.getInstance();
    calendar.set(year, month, day);

    return calendar.getTime();
}

date=(EditText)findViewById(R.id.date_of_birth_textfield);

date.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

           // mMonth = monthOfYear;
           // mDay = dayOfMonth;

        }
    };

private void updateDisplay() {
        date.setText(
                new StringBuilder()
                // Month is 0 `based` so add 1


                .append(mYear).append("-").append(mMonth + 1).append("-").append(mDay).append(""));
        //date.setText(fmtDateAndTime.format(c.getTime()));

}

I'd suggest looking at the DateFormatclass in android. Be careful to import the DateFormat mentioned in the android docs. After that, whatever formatting you want to achieve is really simple. For a basic Aug 12, 2012 you can do this.

我建议查看android中的DateFormat类。小心导入 android 文档中提到的 DateFormat。之后，您想要实现的任何格式都非常简单。对于基本的 2012 年 8 月 12 日，您可以执行此操作。

DatePicker myDatePicker = (DatePicker) findViewById(R.id.mydatepicker);
String selectedDate = DateFormat.getDateInstance().format(myDatePicker.getCalendarView().getDate());

Look at the DateFormatclass to get various other configurations.

查看DateFormat类以获取各种其他配置。

Combined all the answers and made a code snippet out of it.

结合所有答案并从中制作代码片段。

Import datePicker on the top of your class:

在班级顶部导入 datePicker：

import android.widget.DatePicker;

Inside your class declare the following variable:

在您的类中声明以下变量：

private DatePicker dobPicker;

And here is the code to be done in button click event:

这是要在按钮单击事件中完成的代码：

 dobPicker = (DatePicker)findViewById(R.id.dobPicker);
        Integer dobYear = dobPicker.getYear();
        Integer dobMonth = dobPicker.getMonth();
        Integer dobDate = dobPicker.getDayOfMonth();
        StringBuilder sb=new StringBuilder();
        sb.append(dobYear.toString()).append("-").append(dobMonth.toString()).append("-").append(dobDate.toString()).append(" 00:00:00");
        String dobStr=sb.toString();

Where in R.id.dobPicker, dobPicker is your datePicker in the layout xml file. This gives you a string at the end, which could be stored or sent to the server.

在 R.id.dobPicker 中，dobPicker 是布局 xml 文件中的 datePicker。这会在最后为您提供一个字符串，该字符串可以存储或发送到服务器。

Simple Method for Getting Date and Time from a DatePicker and a TimePicker

从 DatePicker 和 TimePicker 获取日期和时间的简单方法

Caveat: it uses JodaTime's DateTimeas the return. You can modify it to use whatever you like.

警告：它采用JodaTime的DateTime作为回报。您可以修改它以使用您喜欢的任何内容。

 // Gets the Date and Time from a DatePicker and TimePicker and return a JodaTime DateTime from them, in current timezone.
 //
 private DateTime getDateTimeFromPickers( int DatePickerId, int TimePickerId ) {
     DatePicker dp = (DatePicker) findViewById(DatePickerId);
     TimePicker tp = (TimePicker) findViewById(TimePickerId);

     String year    = Integer.toString(dp.getYear()) ;
     String month   = StringUtils.leftPad( Integer.toString(dp.getMonth() + 1), 2, "0" );
     String day     = StringUtils.leftPad( Integer.toString(dp.getDayOfMonth()), 2, "0" );
     String hour    = StringUtils.leftPad( Integer.toString(tp.getCurrentHour()), 2, "0" );
     String minutes = StringUtils.leftPad( Integer.toString(tp.getCurrentMinute()), 2, "0" );

     String dateTime = year + "-" + month + "-" + day + "T" + hour + ":" + minutes + ":00.000";

     return DateTime.parse(dateTime);
 }

Hope that helps.

希望有帮助。

I would do it as:

我会这样做：

    Calendar calendar = Calendar.getInstance();
    calendar.set(dp.getYear(), dp.getMonth(), dp.getDayOfMonth(), Tp.getCurrentHour(), Tp.getCurrentMinute());
    DateFormat gmtFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    TimeZone gmtTime = TimeZone.getTimeZone("GMT");
    gmtFormat.setTimeZone(gmtTime);
    String mydate = ""+ gmtFormat.format(calendar.getTime());

p.s dp and tp are date pickers and time picker in android.

ps dp 和 tp 是 android 中的日期选择器和时间选择器。

StringBuilder sb=new StringBuilder();
        sb.append(myYear).append("-").append(myMonth).append("-").append(myDay);
    String str=sb.toString();
    edittext.setText(str);

Try bellow with Format Ex: 24 December 2014.

试试下面的格式，例如：2014 年 12 月 24 日。

            DatePicker datePicker = (DatePicker) findViewById(R.id.datepicker_inspection);
            SimpleDateFormat df = new SimpleDateFormat("dd MMMM yyyy");
            String inspectiondate = df.format(new Date(datePicker.getYear() - 1900, datePicker.getMonth(), datePicker.getDayOfMonth()));
