Android:如何在DatePicker元素中更改所选日期的颜色? [英] Android: How to change the selected date's color in a DatePicker element?

问题描述

我是android编程的新手，我想在布局中使用DatePicker元素.我能够成功使用它，但无法弄清楚如何更改其选定的日期颜色.我已经在该站点上阅读了许多主题，他们谈论在DatePickerDialog中更改颜色.我已经尝试对DatePicker元素采用类似的方法，但是无法做到.我可以使用calendarTextColor属性更改日期的textColor.我的布局文件代码如下:

I am new to android programming and I want to use DatePicker element in my layout. I am able to use it successfully but I can't figure out how to change its selected date color. I have read many threads on this site and they talk about changing color in a DatePickerDialog. I have tried to follow similar approaches for the DatePicker element but could not do it. I can change the date's textColor using calendarTextColor attribute. My code for layout file is as follows:

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center">

            <DatePicker
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/datePicker"
                android:datePickerMode="calendar"
                android:spinnersShown="false"
                android:layout_gravity="center"

                android:layout_marginTop="-52dp"
                android:layout_marginBottom="-20dp"
                style="@style/MyDatePickerStyleTheme"
                />

</LinearLayout>

这是对应的styles.xml代码:

And here is the corresponding styles.xml code:

<style name="MyDatePickerStyleTheme" parent="@android:style/Theme.Holo.Light.Dialog">
    <item name="colorAccent"> #00ff00 </item>

    <item name="android:datePickerStyle">@style/MyDatePickerStyle</item>
    <item name="android:colorPrimary"> #00ff00 </item>
    <item name="android:colorPrimaryDark"> #00ff00 </item>
    <item name="android:colorAccent"> #00ff00 </item>
    <item name="android:backgroundTint"> #00ff00 </item>
    <!-- <item name="android:calendarTextColor"> #00ff00 </item> -->


</style>

<style name="MyDatePickerStyle">
    <item name="android:calendarTextColor"> #00ff00 </item>
</style>

我想补充一些要点:

Some extra points I like to add:

如果将
1. android:calendarTextColor属性放在MyDatePickerStyleTheme中，则该属性有效，但在MydatePickerStyle中放入时，该属性不起作用.
   换句话说，后来的主题样式没有任何作用.
2. 在不同的android版本(Lollipop和Marshmallow)上，相同的代码提供了截然不同的布局.
3. 我现在只想更改选定的日期颜色，但是如何以一种很好的方式更改日期和其他样式之间的间距.

1. android:calendarTextColor attribute is working if I put it inside MyDatePickerStyleTheme but not working when putting inside MydatePickerStyle.
   In other words the later theme style is not having any effect.
2. On different android versions (Lollipop and Marshmallow), same code gives very different looking layouts.
3. I just want to change selected date color for now, but how to change spacing between the dates and other styles in a good manner.

任何帮助将不胜感激.

推荐答案

添加到您的styles.xml

Add to your styles.xml

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

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

然后在布局的视图中添加 android:theme 属性，而不是 style

Then in the layout where is your view, add the android:theme attribute, instead of the style

<DatePicker
     android:theme="@style/MyDatePickerDialogTheme"
     android:id="@+id/datePicker"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" />
