我尝试过日期选择器正在运行

I tried date picker is working

物料日期选择器

//Creating a MaterialDatePicker.Builder instance that gives us a single date selector.
val builder : MaterialDatePicker.Builder<*> = MaterialDatePicker.Builder.datePicker() // 1
//Building-up the MaterialDatePicker by calling a builder.build function
val picker : MaterialDatePicker<*> = builder.build()  // 2
//Display the Material Date Picker.
picker.show(requireActivity().supportFragmentManager, picker.toString())   // 3

简单的时间选择器

  val cal = Calendar.getInstance()
            val timeSetListener = TimePickerDialog.OnTimeSetListener { _, hour, minute ->
                cal.set(Calendar.HOUR_OF_DAY, hour)
                cal.set(Calendar.MINUTE, minute)
                //textView.text = SimpleDateFormat("HH:mm").format(cal.time)
            }
            val time = TimePickerDialog(context, timeSetListener, cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE), true)
            time.setTitle("")
            time.show()

推荐答案

要使用材料时间选择器，请将以下依赖项添加到项目的build.gradle文件中:

To use MATERIAL TIME PICKER, add the following dependency to your project's build.gradle file:

   implementation 'com.google.android.material:material:1.3.0-alpha02'

科特林时间选择器使用的材料:1.3.0-alpha02

Kotlin time picker using material:1.3.0-alpha02

val timePickerDialog = MaterialTimePicker.newInstance();
            timePickerDialog.show(requireActivity().supportFragmentManager, "fragment_tag");
            // Types of formats for the time pickeer
            timePickerDialog.setTimeFormat(TimeFormat.CLOCK_12H)//CLOCK_24H
            timePickerDialog.setListener { dialog: MaterialTimePicker ->
                val newHour = dialog.hour
                val newMinute = dialog.minute
}
