<resources>
    <style name="CustomDatePicker" parent="Theme.AppCompat.Light.Dialog">
        <item name="colorAccent">@color/your_color</item>
        <item name="android:windowBackground">@color/your_background_color</item>
    </style>
</resources>

DatePickerDialog datePickerDialog = new DatePickerDialog(this, R.style.CustomDatePicker, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        // 处理日期选择事件
    }
}, year, month, day);

datePickerDialog.show();

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
