更改Android 5.0的Datepicker对话框颜色 [英] Change Datepicker dialog color for Android 5.0
问题描述
是否可以更改android 5.0的datepicker（以及timepicker）配色方案？
我已经尝试设置重音色， t工作（无论是否有 android：）：
！ - colorPrimary用于默认动作栏背景 - >
< item name =colorPrimary> @ color / purple< / item>
<！ - colorPrimaryDark用于状态栏 - >
< item name =colorPrimaryDark> @ color / purple_tint< / item>
<！ - colorAccent用作colorControlActivated
的默认值，用于绘制小部件 - >
< item name =colorAccent> @ color / purple_tint< / item>
从原始：
如下所示：
Neil的建议导致全屏 DatePicker 是父主题的选择：
;！ - Theme.AppCompat.Light不是一个对话框主题 - >
< style name =DialogThemeparent =** Theme.AppCompat.Light **>
< item name =colorAccent> @ color / blue_500< / item>
< / style>
此外，如果你去这条路线，你必须在创建 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（）;
在我看来，这不是很好。应该尝试将样式保留在java和styles.xml / themes.xml中。
我同意Neil的建议，有一点改变父主题可以说， Theme.Material.Light.Dialog ）将会得到你想要的结果。但是，另一种方式是：
在第一次检查时，我们遇到了 datePickerStyle ，它定义了以下内容： code> headerBackground （您想要更改的内容）， dayOfWeekBackground 以及其他一些文本颜色和文本样式。 / p>
覆盖此应用程序主题中的此属性将无法正常工作。 DatePickerDialog 使用可由属性 datePickerDialogTheme 分配的单独主题。因此，为了使我们的更改生效，我们必须在覆盖 datePickerDialogTheme 之前覆盖 datePickerStyle
这里我们去：
覆盖 datePickerDialogTheme 在您的应用程式基础主题中：
< style name =AppBaseThemeparent =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您的应用程序的基础主题：它可以是 Theme.Material.Dialog 或 Theme.Material.Light。对话框：
< style name =MyDatePickerDialogThemeparent =android：Theme.Material。 Light.Dialog>
< item name =android：datePickerStyle> @ style / MyDatePickerStyle< / item>
< / style>
我们已经覆盖了 datePickerStyle code> MyDatePickerStyle 。父母的选择将再次取决于您的应用程序的基础主题： Widget.Material.DatePicker 或 Widget.Material.Light.DatePicker 。根据您的要求定义：
< style name =MyDatePickerStyleparent =@ android：style / Widget.Material .Light.DatePicker>
< item name =android：headerBackground> @ color / chosen_header_bg_color< / item>
< / style>
目前，我们只是覆盖 headerBackground 默认情况下设置为？attr / colorAccent （这也是Neil建议改变背景的原因）。但是有很多定制可能：
dayOfWeekBackground
dayOfWeekTextAppearance
headerMonthTextAppearance
headerDayOfMonthTextAppearance
headerYearTextAppearance
headerSelectedTextColor
yearListItemTextAppearance
yearListSelectorColor
calendarTextColor
calendarSelectedTextColor
如果您不想要这么多的控件（自定义），则不需要覆盖 datePickerStyle 。 colorAccent 控制大部分 DatePicker的颜色。所以，在 MyDatePickerDialogTheme 内的 c> colorAccent 中，只能执行
< style name =MyDatePickerDialogThemeparent =android：Theme.Material.Light.Dialog>
< item name =android：colorAccent> @ color / date_picker_accent< / item>
<！ - 不需要重写'datePickerStyle' - >
<！ - < item name =android：datePickerStyle> @ style / MyDatePickerStyle< / item> - >
< / style>
覆盖 colorAccent 为您提供额外的好处更改确定& CANCEL 文字颜色也是如此。不是很糟糕。
这样你就不必向 DatePickerDialog的构造函数提供任何样式信息。一切都已经正确连接：
DatePickerDialog dpd = new DatePickerDialog（this，new DatePickerDialog.OnDateSetListener（）{
@覆盖
public void onDateSet（DatePicker view，int year，int monthOfYear，int dayOfMonth）{
}
}，2015，5，22）;
dpd.show（）;
Is it possible to change the datepicker (and also the timepicker) colour scheme for android 5.0?
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>
From original:
To something like this:
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>
Moreover, if you go this route, you have to specify the theme while creating the 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();
This, in my opinion, is not good. One should try to keep the styling out of java and inside styles.xml/themes.xml.
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:
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.
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.
Here we go:
Override datePickerDialogTheme inside your app's base theme:
<style name="AppBaseTheme" parent="android:Theme.Material.Light">
....
<item name="android:datePickerDialogTheme">@style/MyDatePickerDialogTheme</item>
</style>
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>
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>
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
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>
Overriding colorAccent gives you the added benefit of changing OK & CANCEL text colors as well. Not bad.
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();
