Android 2022 -最简单直接的方法:

的变化

/res/values/themes.xml

FROM

<!-- Secondary brand color. -->
<item name="colorSecondary">@color/teal_200</item>
<item name="colorSecondaryVariant">@color/teal_700</item>

TO

<!-- Secondary brand color. -->
<item name="colorSecondary">@color/purple_500</item>
<item name="colorSecondaryVariant">@color/purple_700</item>

您可以为开关小部件自定义样式 在自定义样式时使用颜色重音作为默认值

<style name="switchStyle" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorPrimary</item>    <!-- set your color -->
</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"

<androidx.appcompat.widget.SwitchCompat
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                app:thumbTint="@color/white"
                app:trackTint="@drawable/checker_track"/>

在checker_track.xml中:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/lightish_blue" android:state_checked="true"/>
    <item android:color="@color/hint" android:state_checked="false"/>
</selector>

创建自己的9-patch图像，并将其设置为切换按钮的背景。

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>

编辑:

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">
