What is the difference between Button and Androidx.appcompat.widget.AppCompatButton in Android Devel-CodePudding

I am trying to create a Sign Up page in the latest Android Studio Arctic. So I am trying to customize and style the buttons using Button Class, but no observable changes were made, until I used AppCompatButton, and all the styles and customization for the button were implemented. I want an elaboration between the two Views and why I could not make the changes using Button Class. Thanks.

These are the codes for AppCompatButton and Button

<androidx.appcompat.widget.AppCompatButton
                android:id="@ id/sign_up_text"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="5dp"
                android:background="@drawable/button_border_signin"
                android:elevation="0dp"
                android:text="Sign Up"
                android:textColor="#e0e0e0e0"
                android:textStyle="bold" />

Button

<Button
                android:id="@ id/sign_up_text"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="5dp"
                android:background="@drawable/button_border_signin"
                android:elevation="0dp"
                android:text="Sign Up"
                android:textColor="#e0e0e0e0"
                android:textStyle="bold" />

Possible Reason

You might be using some features that are not compatible for older versions in your background drawable file.

Difference between Button and AppCompatButton

An AppCompatButton is simply a Button which supports compatible features on older versions of the platform, including:

Allows dynamic tint of its background via the background tint methods in ViewCompat.
Allows setting of the background tint using R.attr.backgroundTint and R.attr.backgroundTintMode.
Allows setting of the font family using R.attr.fontFamily

This will automatically be used when you use Button in your layouts and the top-level activity / dialog is provided by appcompat. You should only need to manually use this class when writing custom views.
