Java Android日期时间选择器在一个对话框中
我正在为我的Android应用程序使用材料Java Android日期时间选择器在一个对话框中,java,android,kotlin,material-design,datetimepicker,Java,Android,Kotlin,Material Design,Datetimepicker,我正在为我的Android应用程序使用材料日期时间选择器。但是我想将日期和时间选择器组合在一个对话框中 我跟在后面。但是我需要在日期选择之后选择时间 请建议执行此操作的可能方法。尝试以下代码： CustomDateTimePicker.java import android.app.Activity; import android.app.Dialog; import android.content.DialogInterface; import android.view.Gravity; im

如果需要在选择日期后立即选择时间，只需在选择日期后自动显示
TimePickerDialogTimePickerDialogmdtp\u time\u picker\u dialog.xml中进行一些自定义，就可以添加TextView
来显示选定的文本
另一个选项是合并mdtp\u time\u picker\u dialog.xml
和mdtp\u date\u picker\u 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零件可见性设置为GONE
，并在需要切换选择器时切换可见性
第二种解决方案更难实现，因为除了布局之外，还必须合并所有控件和侦听器
如果希望用户同时看到这两个选择器，我认为实际上需要自己设计一个新视图。该库布局不适用于此。您可以在DatePicker
设置日期之后调用TimePicker
。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();
}

再次感谢Enamul Haque的创意。使用这个简单的代码。。我正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() {

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

date.set(Calendar.MINUTE, minute);

// Toast.makeText(getContext(),"The choosen one " + date.getTime(),Toast.LENGTH_SHORT).show();
datetime.setText(new SimpleDateFormat("dd-MMM-yyyy h:mm a").format(date.getTime()));
}

您可以在Android中使用选择器
逐个获取日期
和时间
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();
}
});
如果您需要更多关于
.Kotlin
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中对闭包的支持，它变得更简单。以下函数应放在片段
或活动
中。requireContext（）
方法是Fragment
的成员。如果您使用的是活动
，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() }
就这样
如果您想根据用户的设置以12小时或24小时格式显示时钟，请将false
替换为DateFormat.is24HourFormat（requireContext（））
基于@，我制作了一个对象，用于在Kotlin中显示日期时间选择器
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()
}
}
您可以使用活动中的对象，如下所示：
// 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()
您可以检查此ResultCallback日期ResultCallback
Calendar getDate = Calendar.getInstance();
cDay = getDate.get(Calendar.DAY_OF_MONTH);
cMonth = getDate.get(Calendar.MONTH);
cYear = getDate.get(Calendar.YEAR);
