First, you need to add some colors in the colors.xml file located in the res/values directory.


<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="black">#FF000000</color>
    <color name="white">#FFFFFFFF</color>
    <color name="primaryColor">#512DA8</color> <!-- Deep Purple -->
    <color name="primaryDarkColor">#311B92</color>
    <color name="accentColor">#FF6F00</color>  <!-- Amber -->
    <color name="backgroundColor">#F3F4F6</color> <!-- light grey -->
    <color name="buttonColor">#00ACC1</color> <!-- Teal -->
    <color name="textColor">#212121</color>
</resources>


Now you need to set the style in your themes.xml file located in the res/values directory.


<style name="Theme.DoctorApp" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <item name="colorPrimary">@color/primaryColor</item>
        <item name="colorPrimaryVariant">@color/primaryDarkColor</item>
        <item name="colorOnPrimary">@android:color/white</item>
        <item name="colorAccent">@color/accentColor</item>
        <item name="android:colorBackground">@color/backgroundColor</item>
        <item name="android:textColor">@color/textColor</item>
        <item name="android:buttonStyle">@style/Widget.MaterialComponents.Button</item>
    </style>


I have added a button click animation. If you want to use this animation, make sure to create a directory named animator inside the res folder, and within it, create a resource file named button_press.xml. If you do not wish to use the animation, you can remove the related code from the Java file.

button_press.xml


<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <objectAnimator
            android:propertyName="translationZ"
            android:duration="100"
            android:valueTo="2dp"
            android:valueType="floatType" />
    </item>
    <item>
        <objectAnimator
            android:propertyName="translationZ"
            android:duration="100"
            android:valueTo="6dp"
            android:valueType="floatType" />
    </item>
</selector>
