How Change style of TimePicker Dialog

Question

Is it possible to change the TimePicker colour scheme?

I've tried, but the TimePicker pop-up opens on full screen.

 TimePickerDialog mTimePicker;

    mTimePicker = new TimePickerDialog(AddAlarm.this,R.style.Time_picker, new TimePickerDialog.OnTimeSetListener() {
        @Override
        public void onTimeSet(TimePicker timePicker, int selectedHourLocal, int selectedMinuteLocal) {

        }
    }, hour, minute, false);//Yes 24 hour time
    mTimePicker.setTitle("Select Time");
    mTimePicker.show();

And the style is

 <style name="Time_picker">
    <item name="android:numbersTextColor" tools:targetApi="lollipop">#ffffff</item>
    <item name="android:numbersBackgroundColor" tools:targetApi="lollipop">#643B85</item>
    <item name="android:numbersSelectorColor" tools:targetApi="lollipop">#88000000</item>
    <item name="android:headerBackground">#643B85</item>
</style>

Answer 1

Use one of the five built-in AlertDialog themes:

THEME_TRADITIONAL - The traditional (pre-Holo) alert dialog theme

THEME_HOLO_DARK - The holographic alert theme with a dark background

THEME_HOLO_LIGHT - The holographic alert theme with a light background

THEME_DEVICE_DEFAULT_DARK - The device's default alert theme with a dark background.

THEME_DEVICE_DEFAULT_LIGHT - The device's default alert theme with a light background.

For instance:

       MyTimePickerDialog timePickerDialog = new MyTimePickerDialog (AddAlarm.this,
        TimePickerDialog.THEME_HOLO_DARK, timeSetListener, 0, 0, true);
