如何更改 Android 5.0 的 DatePicker 对话框颜色

Overriding this attribute in your app's theme will not work. DatePickerDialog uses a separate theme assignable by the attribute datePickerDialogTheme. So, for our changes to take affect, we must override datePickerStyle inside an overriden datePickerDialogTheme.

我们开始吧:

在应用的基本主题中覆盖 datePickerDialogTheme:

Override datePickerDialogTheme inside your app's base theme:

<style name="AppBaseTheme" parent="android:Theme.Material.Light">
    ....
    <item name="android:datePickerDialogTheme">@style/MyDatePickerDialogTheme</item>
</style>

定义 MyDatePickerDialogTheme.父主题的选择取决于您应用的基本主题:它可以是 Theme.Material.Dialog 或 Theme.Material.Light.Dialog:

Define MyDatePickerDialogTheme. The choice of parent theme will depend on what your app's base theme is: it could be either Theme.Material.Dialog or Theme.Material.Light.Dialog:

<style name="MyDatePickerDialogTheme" parent="android:Theme.Material.Light.Dialog">
    <item name="android:datePickerStyle">@style/MyDatePickerStyle</item>
</style>

我们已经用样式 MyDatePickerStyle 覆盖了 datePickerStyle.父级的选择将再次取决于您应用的基本主题是什么:Widget.Material.DatePicker 或 Widget.Material.Light.DatePicker.根据您的要求定义它:

We have overridden datePickerStyle with the style MyDatePickerStyle. The choice of parent will once again depend on what your app's base theme is: either Widget.Material.DatePicker or Widget.Material.Light.DatePicker. Define it as per your requirements:

<style name="MyDatePickerStyle" parent="@android:style/Widget.Material.Light.DatePicker">
    <item name="android:headerBackground">@color/chosen_header_bg_color</item>
</style>

目前，我们只覆盖默认设置为 ?attr/colorAccent 的 headerBackground(这也是 Neil 建议在更改背景时起作用的原因).但是可以进行很多自定义:

Currently, we are only overriding headerBackground which by default is set to ?attr/colorAccent (this is also why Neil suggestion works in changing the background). But there's quite a lot of customization possible:

dayOfWeekBackground
dayOfWeekTextAppearance
headerMonthTextAppearance
headerDayOfMonthTextAppearance
headerYearTextAppearance
headerSelectedTextColor
yearListItemTextAppearance
yearListSelectorColor
calendarTextColor
calendarSelectedTextColor

如果您不想要这么多的控​​制(自定义)，则无需覆盖 datePickerStyle.colorAccent 控制大部分 DatePicker 的 颜色.因此，在 MyDatePickerDialogTheme 中仅覆盖 colorAccent 应该可以工作:

If you don't want this much control (customization), you don't need to override datePickerStyle. colorAccent controls most of the DatePicker's colors. So, overriding just colorAccent inside MyDatePickerDialogTheme should work:

<style name="MyDatePickerDialogTheme" parent="android:Theme.Material.Light.Dialog">
    <item name="android:colorAccent">@color/date_picker_accent</item>

    <!-- No need to override 'datePickerStyle' -->
    <!-- <item name="android:datePickerStyle">@style/MyDatePickerStyle</item> -->
</style>

重写 colorAccent 为您提供更改 OK 的额外好处 &CANCEL 文本颜色也是如此.还不错.

Overriding colorAccent gives you the added benefit of changing OK & CANCEL text colors as well. Not bad.

这样您就不必向 DatePickerDialog 的 构造函数提供任何样式信息.一切都已正确接线:

This way you don't have to provide any styling information to DatePickerDialog's constructor. Everything has been wired properly:

DatePickerDialog dpd = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

    }
 }, 2015, 5, 22);

 dpd.show();
