I created a library that you can create your custom themes and change them dynamically with ripple animation.

check it here: https://github.com/imandolatkia/Android-Animated-Theme-Manager

also in this repository, there is a sample app that you can see what should you do.

First, create a folder inside /app/src/main/res/ directory & name it values-night. It will show in Android Studio as values(night) in the project pane. Then for each configuration you need separate files. Such as colors, styles etc. Here colors and style are main.

Here is a sample:

For normal mode

colors.xml (as you wish)

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#6C63FF</color>
    <color name="colorPrimaryDark">#6C63FF</color>
    <color name="colorAccent">#03DAC5</color>
    
    <color name="mainText">#2D313D</color>
    <color name="textAlt">#8D8F97</color>

    <color name="mainBackground">#ffffff</color>
</resources>

and styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

For Night mode

Now in /app/src/main/res/values-night/ directory do the same as above. Just change the color that matches night mode. For instance:

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#6C63FF</color>
    <color name="colorPrimaryDark">#2D313D</color>
    <color name="colorAccent">#03DAC5</color>
    
    <color name="mainText">#ffffff</color>
    <color name="textAlt">#8D8F97</color>

    <color name="mainBackground">#2D313D</color>
</resources>

and styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

To switch from one mode to another, add these line in activity:

switch_btn.setOnClickListener(View.OnClickListener {
    if(isNightModeOn){
        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO)
        switch_btn.text = "Enable Dark Mode"
    } else {
        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
        switch_btn.text = "Disable Dark Mode"
    }
})
