更改日期选择器对话框颜色为Android 5.0 [英] Change Datepicker dialog color for Android 5.0
问题描述
是否有可能改变的日期选择器（以及timepicker）为Android 5.0的配色方案？
Is it possible to change the datepicker (and also the timepicker) colour scheme for android 5.0?
我tryed设置口音的颜色，但是这并不能正常工作（带或不带机器人：）：
I've tryed setting the accent colours, but this doesn't work (both with and without android:):
<!-- colorPrimary is used for the default action bar background -->
<item name="colorPrimary">@color/purple</item>
<!-- colorPrimaryDark is used for the status bar -->
<item name="colorPrimaryDark">@color/purple_tint</item>
<!-- colorAccent is used as the default value for colorControlActivated
which is used to tint widgets -->
<item name="colorAccent">@color/purple_tint</item>
这是原文：

要像这样：

推荐答案
之所以尼尔的建议将导致在全屏的DatePicker 是父主题的选择：
The reason why Neil's suggestion results in a fullscreen DatePicker is the choice of parent theme:
<!-- Theme.AppCompat.Light is not a dialog theme -->
<style name="DialogTheme" parent="**Theme.AppCompat.Light**">
<item name="colorAccent">@color/blue_500</item>
</style>
此外，如果你走这条路，你必须在创建指定主题 DatePickerDialog ：
// R.style.DialogTheme
new DatePickerDialog(MainActivity.this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
//DO SOMETHING
}
}, 2015, 02, 26).show();
这在我看来，是不好的。每个人都应该尽量保持造型的Java应用和内部styles.xml /的themes.xml。
This, in my opinion, is not good. One should try to keep the styling out of java and inside styles.xml/themes.xml.
我不同意，尼尔的建议下，带着几分改变（改变父主题说， Theme.Material.Light.Dialog ）会得到你想要的结果。但是，这里的另一种方式：
I do agree that Neil's suggestion, with a bit of change (changing the parent theme to say, Theme.Material.Light.Dialog) will get you the desired result. But, here's the other way:
在第一次检查，我们遇到 datePickerStyle 这件事定义，如： headerBackground （你正在尝试变化）， dayOfWeekBackground ，和一些其他的文本颜色和文本样式。
On first inspection, we come across datePickerStyle which defines things such as: headerBackground(what you are trying to change), dayOfWeekBackground, and a few other text-colors and text-styles.
覆盖这个属性在你的应用程序的主题将无法正常工作。 DatePickerDialog 的属性使用一个单独的主题分配 datePickerDialogTheme 。因此，对于我们的更改生效，我们必须替换 datePickerStyle 内部的重写 datePickerDialogTheme
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.
在这里，我们去：
覆盖 datePickerDialogTheme 您的应用程序的基本主题里面：
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 。父主题的选择将取决于你的应用程序的基本主题是：它可以是 Theme.Material.Dialog 或 Theme.Material.Light。对话：
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>
我们已经覆盖 datePickerStyle 的风格 MyDatePickerStyle 。家长的选择将再次取决于你的应用程序的基本主题是：要么 Widget.Material.DatePicker 或 Widget.Material.Light.DatePicker 。其定义为按您的要求：
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 headerBackground 在缺省情况下设置为？ATTR / colorAccent （这也是为什么尼尔建议在改变背景的作品）。但还有相当多的定制成为可能：
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
如果你不想这么多控制（定制），你并不需要重写 datePickerStyle 。 colorAccent 控制大多数的的DatePicker的的颜色。因此，仅仅覆盖 colorAccent 在 MyDatePickerDialogTheme 应该工作：
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 让你改变确定＆放大器的好处; 取消文本颜色为好。不坏。
Overriding colorAccent gives you the added benefit of changing OK & CANCEL text colors as well. Not bad.
这样，您就不必提供任何样式信息 DatePickerDialog的的构造。一切都已经连接正常：
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();
