CardView with An ImageView Inside It

In this Android tutorial, you'll learn how to create a visually appealing user interface using a 'CardView' widget. Inside the 'CardView', you'll place an 'ImageView' that displays an image fetched from the '@drawable/mobile_icon'. This tutorial will teach you essential concepts such as working with layouts, incorporating images into your app, and enhancing user experience with material design elements like 'CardView'.

using a ‘CardView’ with an ‘ImageView’ inside it, where the ‘ImageView’ displays an image from ‘@drawable/mobile_icon’

1. Add CardView Dependency: First, ensure you have the ‘CardView’ dependency in your ‘build.gradle’ file (Module: app). Add this line if it's not already there:

     implementation 'androidx.cardview:cardview:1.0.0'

2.Update activity_main.xml: Here's how your ‘activity_main.xml’ should look:


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        app:cardCornerRadius="8dp">


        <ImageView
            android:id="@+id/imageView"
            android:layout_width="match_parent"
            android:layout_height="200dp" <!-- Set height as per your requirement -->
            android:scaleType="centerCrop" <!-- Adjust scale type as per your image aspect ratio -->
            android:src="@drawable/mobile_icon" />


    </androidx.cardview.widget.CardView>


</RelativeLayout>

CardView with ImageView - Layout and Customization Guide

    • In this layout:

      • The CardView wraps around the ImageView.
      • Adjust layout_width, layout_height, and other attributes (cardCornerRadius for rounded corners, for example) based on your design requirements.
      • The ImageView inside the CardView uses android:src="@drawable/mobile_icon" to set the image. Replace mobile_icon with the name of your drawable resource file without the file extension (e.g., mobile_icon.png would be referenced as @drawable/mobile_icon).

  2. Adjust as Needed: Modify the dimensions (layout_width, layout_height) and other attributes (cardCornerRadius, scaleType) of both CardView and ImageView according to your specific design preferences.

  3. Ensure Correct Imports: Make sure your activity_main.xml imports the correct namespaces, especially xmlns:app="http://schemas.android.com/apk/res-auto" for CardView attributes.

  4. Further Customization: You can further customize the CardView and ImageView with additional attributes like padding, margins, elevation, etc., as per your app's design requirements.

This layout should give you a CardView containing an ImageView that displays the image mobile_icon.png from your drawable resources. Adjust the dimensions and other attributes as needed to fit your application's UI design.
