如何更改 Android 应用程序中时间选择器的颜色？

Question

As you can see from the image below, I'm using the time picker in my app.
I need to change the color but don't know how...
Thanks for the help.

Answer 1

This can be easily achieved from xml (5.0+ only)

v21/themes.xml

<style name="Theme"
       parent="MyTheme.Base">

    <item name="android:dialogTheme">@style/Theme.Dialog</item> <!-- TimePicker dialog -->
    <item name="android:alertDialogTheme">@style/Theme.Dialog</item> <!-- Alert dialog -->

</style>

<style name="Theme.Dialog"
       parent="android:Theme.Material.Light.Dialog">

    <item name="android:colorAccent">@color/...</item>
    <item name="android:colorPrimary">@color/...</item>
    <item name="android:colorPrimaryDark">@color/...</item>

</style>

Edit Please note that as of Android Support Library 22.1.0 there is a new AppCompatDialog available! http://android-developers.blogspot.de/2015/04/android-support-library-221.html

Answer 2

Try this code

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TimePicker" parent="Theme.AppCompat.Light.Dialog">
        <item name="android:windowIsFloating">true</item>
        <item name="colorAccent">@color/primary</item>
        <item name="colorControlActivated">@color/secondary</item>
        <item name="android:colorPrimary">@color/primary</item>
        <item name="android:colorPrimaryDark">@color/primary</item>
        <item name="android:buttonBarNegativeButtonStyle">@style/DatePickerTheme.ButtonBarButtonStyle</item>
        <item name="android:buttonBarPositiveButtonStyle">@style/DatePickerTheme.ButtonBarButtonStyle</item>
    </style>

    <style name="DatePickerTheme.ButtonBarButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
        <item name="android:textColor">@color/primary</item>
    </style>
</resources>

The first one is colorAccent, the second is colorControlActivated and the last one does not belong to the timepicker, it belongs to dialog so you should apply the an style similar to this post
