/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>

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>

要在不使用style. XML或Java代码的情况下更改Switch样式，您可以将Switch定制为布局XML:

<Switch
        android:id="@+id/checkbox"
        android:layout_width="wrap_content"
        android:thumbTint="@color/blue"
        android:trackTint="@color/white"
        android:checked="true"
        android:layout_height="wrap_content" />

它的属性android:thumbTint和android:trackTint，允许你自定义颜色

下面是这个XML的可视化结果:

当开关状态改变时，我通过更新颜色过滤器解决了这个问题…

public void bind(DetailItem item) {
    switchColor(item.toggle);
    listSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                switchColor(b);
        }
    });
}

private void switchColor(boolean checked) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
        listSwitch.getThumbDrawable().setColorFilter(checked ? Color.BLACK : Color.WHITE, PorterDuff.Mode.MULTIPLY);
        listSwitch.getTrackDrawable().setColorFilter(!checked ? Color.BLACK : Color.WHITE, PorterDuff.Mode.MULTIPLY);
    }
}
