到目前为止，最好从AppCompat中使用SwitchCompat。v7图书馆。然后，您可以使用简单的样式来更改组件的颜色。

values/themes.xml:

<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

它应该正确应用的方式是通过android:theme="@style/ theme。MyTheme” 这也可以应用到父样式，如EditTexts, RadioButtons, Switches, CheckBoxes和ProgressBars:

<style name="My.Widget.ProgressBar" parent="Widget.AppCompat.ProgressBar">

<style name="My.Widget.Checkbox" parent="Widget.AppCompat.CompoundButton.CheckBox">

Android 2022 -最简单直接的方法:

如果你想通过编程改变开关组件颜色，请使用下面的代码:

    binding.switchCompatBackupMedia.thumbTintList =
                ColorStateList.valueOf(Color.parseColor("#00C4D3"))
            binding.switchCompatBackupMedia.trackTintList =
                ColorStateList.valueOf(Color.parseColor("#00C4D31F"))

在Android Lollipop和以上版本中，在你的主题样式中定义它:

<style name="BaseAppTheme" parent="Material.Theme">
    ...
    <item name="android:colorControlActivated">@color/color_switch</item>
</style>

这招对我很管用——

1.values/styles.xml中的代码:

 <style name="SwitchTheme" parent="Theme.AppCompat.Light">
    <item name="android:colorControlActivated">#148E13</item>
</style>

2.在布局文件的交换机中添加以下代码行-:

android:theme="@style/SwitchTheme"
