CardView in Android With Example

CardView is a relatively new feature in Android development that offers a visually appealing way to present various types of data. It introduces rounded corners and elevation to create a sleek and modern look in user interfaces. This component is commonly used in many Android applications, especially for displaying items in lists or within a Recycler View.

Overview of CardView

• CardView is a versatile Android widget that enhances the visual appearance of user interfaces.
• It extends Framelayout, allowing for easy integration across different Android platforms.
• One of the primary purposes of CardView is to provide a rich and sophisticated feel to app designs.

Implementation Steps

Step 1: Create a new Android Studio Project

• Begin by initiating a new project in Android Studio.
• Click on "File" > "New" > "New Project" to start the project creation process.
• Ensure that you select "JAVA" as the language and opt for an "Empty Activity" template.

Step 2: Add material dependency in build.gradle file

• Navigate to "Gradle Scripts" and open the "build.gradle (app)" file.
• Add the required material dependency to the file.
• After adding the dependency, sync your project by clicking on the "Sync Now" option that appears in the top right corner.

Step 3: Add Google repository in the build.gradle file

• Within the build.gradle file of your application project, include the Google repository.
• Ensure that you have the necessary repositories configured to access Jetpack components.

Step 4: Create a simple CardView

• Locate the "activity_main.xml" file in the "app/res/layout" directory.
• Add a new CardView widget to the XML layout to implement a basic CardView.

CardView Widget Overview

• CardElevation Property: Adds elevation to the card view.
• CardCornerRadius: Provides radius to the card view.
• CardBackgroundColor: Specifies the background color of the card view.
• CardMaxElevation: Sets the maximum elevation for the card view.
• CardPreventCornerOverlap: Adds padding to prevent intersections with rounded corners.
• CardUseCompatPadding: Adds padding for consistency across different API versions.

Widgets Inside CardView

• ImageView: Displays an image within the card view.
• TextView: Shows text content in the card view.

Running Your App

Step 5: After configuring, run your application on the emulator or device to view the output.

Cardview Attributes

• cardBackgroundColor: Used to set the background color of the card.
• cardElevation: Determines the elevation of the card. Excessive values may affect design aesthetics.
• cardCornerRadius: Sets the radius around the corners of the card, influencing its edge curvature.
• cardUseCompactPadding: Can be set to true or false. When true, the card applies padding for improved UI appearance.
