微调模式下的时间选取器对话框

Question

在我的项目中，我使用TimepickerDialog来显示TextView中的时间。我的Timepickerdialog显示为时钟，但我希望它显示为旋转器。我该怎么做？

Answer 1

使用此代码显示时间选取器作为微调器

public void showCustomTimePicker()
{
final Calendar myCalender = Calendar.getInstance();
int hour = myCalender.get(Calendar.HOUR_OF_DAY);
int minute = myCalender.get(Calendar.MINUTE);

TimePickerDialog.OnTimeSetListener myTimeListener = new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
if (view.isShown()) {
myCalender.set(Calendar.HOUR_OF_DAY, hourOfDay);
myCalender.set(Calendar.MINUTE, minute);
}
}
};
TimePickerDialog timePickerDialog = new TimePickerDialog(getActivity(), android.R.style.Theme_Holo_Light_Dialog_NoActionBar, myTimeListener, hour, minute, true);
timePickerDialog.setTitle("Choose hour:");
timePickerDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
timePickerDialog.show();
}

Answer 2

使用此代码

TimePickerDialog picker = new TimePickerDialog(MainActivity.this,android.R.style.Theme_Holo_Light_Dialog_NoActionBar,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker tp, int sHour, int sMinute) {
//eText.setText(sHour + ":" + sMinute);
}
}, 2, 3, false);
picker.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
picker .show();

Answer 3

Kotlin：

我使用以下代码使时间选择器处于微调器模式。

private fun showTimePicker() {
// Use the current time as the default values for the picker
val c = Calendar.getInstance()
val hour = c.get(Calendar.HOUR_OF_DAY)
val minute = c.get(Calendar.MINUTE)
// date picker dialog
val timeSetListener = TimePickerDialog.OnTimeSetListener { timePicker, hour, minute ->
c.set(Calendar.HOUR_OF_DAY, hour)
c.set(Calendar.MINUTE, minute)
mSelectedTime = SimpleDateFormat("HH:mm").format(c.time)
root.tvTime.text = mSelectedTime
}
val timePickerDialog = TimePickerDialog(requireContext(),AlertDialog.THEME_HOLO_LIGHT, timeSetListener, hour, minute,
DateFormat.is24HourFormat(requireContext()))
timePickerDialog.show()
}

Answer 4

您所需要的只是指定一个主题并添加下一个样式属性

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="TimePicker" parent="Theme.AppCompat.Light.Dialog">
<item name="android:timePickerMode">spinner</item>
</style>
</resources>

以下是一些相关信息

Answer 5

为微调器模式添加android:timePickerMode = "1"

和

android:timePickerMode="2"时钟模式。

编辑

在TimePickerDialog的构造函数中使用这样的主题

TimePickerDialog timePickerDialog = new TimePickerDialog(DateTimePickerDialogActivity.this, android.R.style.Theme_Holo_Light_Dialog, onTimeSetListener, hour, minute, is24Hour);

Answer 6

TimePickerDialog nTimePickerDialog = new TimePickerDialog(this, 2,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker pTimePicker, int hr, int min) {
TextView.setText(MessageFormat.format("{0}:{1}", hr, min));
}
},
mHour, mMin, false);
nTimePickerDialog.setTitle("Select Intervals");
nTimePickerDialog.show();
