Android日期时间选择器在一个对话框中

标签： android android-fragments material-design datetimepicker

我正在为我的Android应用使用素材private implicit class CounterMap[A](map: Map[A, Int]) { def updateCounter(k: A): Map[A, Int] = map + (k → map.getOrElse(k, 0) + 1) } Date选择器。但我希望在一个对话框中合并Time和Date选择器。

我关注this one。但是我需要在选择日期之后选择时间。

请建议可行的方法。

您可以在TimePicker设置日期后致电DatePicker。像这样...... 

    String date_time = "";
    int mYear;
    int mMonth;
    int mDay;

    int mHour;
    int mMinute;

    et_show_date_time = (EditText) findViewById(R.id.et_show_date_time);
    btn_set_date_time = (Button) findViewById(R.id.btn_set_date_time);

    btn_set_date_time.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            datePicker();

        }
    });

日期选择器：

    private void datePicker(){

    // Get Current Date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    DatePickerDialog datePickerDialog = new DatePickerDialog(this,
            new DatePickerDialog.OnDateSetListener() {

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

                    date_time = dayOfMonth + "-" + (monthOfYear + 1) + "-" + year;
                   //*************Call Time Picker Here ********************
                   tiemPicker();
                }
            }, mYear, mMonth, mDay);
       datePickerDialog.show();
    }

时间选择器

 private void tiemPicker(){
    // Get Current Time
    final Calendar c = Calendar.getInstance();
    mHour = c.get(Calendar.HOUR_OF_DAY);
    mMinute = c.get(Calendar.MINUTE);

    // Launch Time Picker Dialog
    TimePickerDialog timePickerDialog = new TimePickerDialog(this,
            new TimePickerDialog.OnTimeSetListener() {

                @Override
                public void onTimeSet(TimePicker view, int hourOfDay,int minute) {

                    mHour = hourOfDay;
                    mMinute = minute;

                    et_show_date_time.setText(date_time+" "+hourOfDay + ":" + minute);
                }
            }, mHour, mMinute, false);
    timePickerDialog.show();
}

下面是经过测试的Kotlin代码，用于将DatePickerDialog和TimePickerDialog组合在一起。由于Kotlin中封闭的支持，它变得更加简单。以下函数应放在您的Fragment或Activity中。 requireContext()方法是Fragment的成员。如果您使用的是Activity，请改用applicationContext。

private fun pickDateTime() {
    val currentDateTime = Calendar.getInstance()
    val startYear = currentDateTime.get(Calendar.YEAR)
    val startMonth = currentDateTime.get(Calendar.MONTH)
    val startDay = currentDateTime.get(Calendar.DAY_OF_MONTH)
    val startHour = currentDateTime.get(Calendar.HOUR_OF_DAY)
    val startMinute = currentDateTime.get(Calendar.MINUTE)

    DatePickerDialog(requireContext(), DatePickerDialog.OnDateSetListener { _, year, month, day ->
        TimePickerDialog(requireContext(), TimePickerDialog.OnTimeSetListener { _, hour, minute ->
            val pickedDateTime = Calendar.getInstance()
            pickedDateTime.set(year, month, day, hour, minute)
            doSomethingWith(pickedDateTime)
        }, startHour, startMinute, false).show()
    }, startYear, startMonth, startDay).show()
}

在按钮的onClickListener中调用上述函数，如下所示：

button.setOnClickListener { pickDateTime() }

如果要根据用户设置以12小时制或24小时制显示时钟，请将false替换为DateFormat.is24HourFormat(requireContext())

如果您需要在日期选择后立即选择时间，则只需在选择日期后自动显示TimePickerDialog。这是最简单的方法。

当您选择日期时，如果您选择日期时触发了侦听器，则只需将所选日期传递到TimePickerDialog，并在mdtp_time_picker_dialog.xml中进行一些自定义即可添加TextView显示所选文字。

另一个选项是合并mdtp_time_picker_dialog.xml和mdtp_date_picker_dialog.xml，它们是日期选择器对话框和时间选择器对话框的根布局。您可以将时间选择器部件可见性设置为GONE，并在需要切换选择器时切换可见性。

第二个解决方案更难实现，因为除了布局之外，您还必须合并所有控件和侦听器。

如果您希望用户看到两个选择器，我认为您实际上需要自己设计一个新视图。那个库布局不适合这个。

用Google搜索这个问题，发现Enamul Haque的答案很有用。稍微修改了他的代码并得到了这个结果。它的快速解决方案将得到改进，但效果很好）

public class DateTimePicker {

    public void setDateResultCallback(@Nullable ResultCallback<Date> dateResultCallback) {
        this.dateResultCallback = dateResultCallback;
    }

    public long getTime() {
        return calendar.getTimeInMillis();

    private void closeDialogs() {
        if (datePickerDialog != null) {

        public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
            calendar.set(Calendar.YEAR, year);
            calendar.set(Calendar.MONTH, month);
            calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

        }
    };

    private TimePickerDialog.OnTimeSetListener timeSetListener = new TimePickerDialog.OnTimeSetListener() {

    }

    private void timePicker(@NonNull Context context) {
        timePickerDialog = new TimePickerDialog(context,
                timeSetListener,
                calendar.get(Calendar.HOUR_OF_DAY),

    }

    public void release() {
        closeDialogs();
        dateResultCallback = null;
    }

}

通过方法showDialog（...）调用Dialogs，可以在不再需要时释放对象（在活动f.e中的onDestroy（）中）。 再一次 - 感谢Enamul Haque的想法。

使用这个简单的代码..我在我的项目中使用此代码.. 

final Calendar currentDate = Calendar.getInstance();
date = Calendar.getInstance();
            DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(), new DatePickerDialog.OnDateSetListener() {

                @Override
                public void onDateSet(DatePicker datePicker, int year, int monthOfYear, int dayOfMonth) {

                    date.set(year, monthOfYear, dayOfMonth);
                    new TimePickerDialog(getContext(), new TimePickerDialog.OnTimeSetListener() {

您可以在Android中使用Date一步一步获得Time和Pickers。

Calendar getDate = Calendar.getInstance();

         cDay = getDate.get(Calendar.DAY_OF_MONTH);
         cMonth = getDate.get(Calendar.MONTH);
         cYear = getDate.get(Calendar.YEAR);

         timePickerDialog = new TimePickerDialog(DesignActivity.this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                final String AM_PM ;

                if (hourOfDay > 12) {
                    hourOfDay -= 12;
                    AM_PM = "pm";
                } else if (hourOfDay == 0) {
                    hourOfDay += 12;
                    AM_PM = "am";
                } else if (hourOfDay == 12)
                    AM_PM = "pm";
                else
                    AM_PM = "am";

                hour1 = hourOfDay;
                minutes1 = minute;

                DatePickerDialog datePicker = new DatePickerDialog(DesignActivity.this, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {

                        cYear = year;
                        cMonth = month;
                        cDay = dayOfMonth;

                        editText.setText(hour1 + ":" +minutes1 + AM_PM  + "     " + cDay + "/" + cMonth + "/" + cYear);

                    }
                },cYear,cMonth,cDay);

                datePicker.show();

            }
        },hour1,minutes1,false);

        timePickerDialog.show();

    }
});

基于@ Yogesh Umesh Vaity's answer，我制作了一个对象，用于在Kotlin中显示DateTimePicker。

class DateTimePicker(val context: Context, var pickTime:Boolean = false, var calendar: Calendar = Calendar.getInstance(),
                     var callback: (it : DateTimePicker) -> Unit) {

    companion object{
        @JvmStatic
        fun getFormat(format : String) : String{
            when(format){
                "d" -> return "dd/MM/yyyy"
                "t" -> return "HH:mm"
                "dt" -> return "dd/MM/yyyy HH:mm"
            }
            return "dd/MM/yyyy"
        }
    }

    fun show(){
        val startYear = calendar.get(Calendar.YEAR)
        val startMonth = calendar.get(Calendar.MONTH)
        val startDay = calendar.get(Calendar.DAY_OF_MONTH)
        val startHour = calendar.get(Calendar.HOUR_OF_DAY)
        val startMinute = calendar.get(Calendar.MINUTE)

        DatePickerDialog(context, DatePickerDialog.OnDateSetListener { _, year, month, day ->
            if(pickTime) {
                TimePickerDialog(context, TimePickerDialog.OnTimeSetListener { _, hour, minute ->
                    calendar.set(year, month, day, hour, minute)
                    callback(this)
                }, startHour, startMinute, true).show()
            } else {
                calendar.set(year,month,day)
                callback(this)
            }
        }, startYear, startMonth, startDay).show()
    }

    fun showTime(){
        val startYear = calendar.get(Calendar.YEAR)
        val startMonth = calendar.get(Calendar.MONTH)
        val startDay = calendar.get(Calendar.DAY_OF_MONTH)
        val startHour = calendar.get(Calendar.HOUR_OF_DAY)
        val startMinute = calendar.get(Calendar.MINUTE)

        TimePickerDialog(context, TimePickerDialog.OnTimeSetListener { _, hour, minute ->
            calendar.set(startYear, startMonth, startDay, hour, minute)
            callback(this)
        }, startHour, startMinute, true).show()
    }
}

您可以像这样使用Activity中的对象：

// Open Date Picker only and set an EditText
DateTimePicker(this){
    val sdf = SimpleDateFormat(DateTimePicker.getFormat("d"), Locale.getDefault())
    editText.setText(sdf.format(it.calendar.time))
}.show()

// Open Date Picker then Time picker and set an EditText
DateTimePicker(this, true){
    val sdf = SimpleDateFormat(DateTimePicker.getFormat("dt"), Locale.getDefault())
    editText.setText(sdf.format(it.calendar.time))
}.show()

// Open Time Picker only and set an EditText
DateTimePicker(this){
    val sdf = SimpleDateFormat(DateTimePicker.getFormat("t"), Locale.getDefault())
    editText.setText(sdf.format(it.calendar.time))
}.showTime()

// Use your own calendar object if you prefer to use your pre-configured calendar
val myCalendar = Calendar.getInstance()
myCalendar.set(Calendar.YEAR, 1995)
DateTimePicker(this, false, myCalendar){
    val sdf = SimpleDateFormat(DateTimePicker.getFormat("d"), Locale.getDefault())
    editText.setText(sdf.format(it.calendar.time))
}.show()
