ImageView class is used to display any kind of image resource in the android application either it can be or (it is a general abstraction for anything that can be drawn in Android). ImageView class or android.widget.ImageView inherits the android.view.View class which is the subclass of Kotlin.Any class. Application of ImageView is also in applying tints to an image in order to reuse a drawable resource and create overlays on background images. Moreover, ImageView is also used to control the size and movement of an image. 

Adding an ImageView to an activity

Whenever ImageView is added to an activity, it means there is a requirement for an image resource. Thus it is oblivious to provide an Image file to that ImageView class. It can be done by adding an image file that is present in the Android Studio itself or we can add our own image file. Android Studio owns a wide range of drawable resources which are very common in the android application layout. The following are the steps to add a drawable resource to the ImageView class.

Note: The steps are performed on Android Studio version 4.0

Open the activity_main.xml file in which the image is to be added 

activity.xml file in which image is to be added

Switch from code view to the design view of the activity_main.xml file. 

Design view of the activity.xml file

For adding an image from Android Studio Drag the ImageView widget to the activity area of the application, a pop-up dialogue box will open choose from the wide range of drawable resources and click “OK”. 

Adding a drawable resource to the activity

For adding an image file other than Android Studio drawable resources: 
Click on the “Resource Manager” tab on the leftmost panel and select the “Import Drawables” option. 

Select Import Drawables option to add image file

Select the path of the image file on your computer and click “OK”. After that set, the “Qualifier type” and “value” of the image file according to your need and click “Next” then “Import”. 

Providing value to Qualifier type for the image

Drag the ImageView class in the activity area, a pop-up dialogue box will appear which contain your imported image file. Choose your image file and click “OK”, your image will be added to the activity. 

Adding image to the activity

Note: After adding an image set its constraints layout both vertically and horizontally otherwise it will show an error.

XML Attributes of ImageView 

XML Attribute


android:idTo uniquely identify an image view
android:src/app:srcCompatTo add the file path of the inserted image
android:backgroundTo provide a background color to the inserted image
android:layout_widthTo set the width of the image
android:layout_heightTo set the height of the image
android:paddingTo add padding to the image from left, right, top, or bottom of the view
android:scaleTypeTo re-size the image or to move it in order to fix its size


Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio.

Step 2: Working with the activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file. 


<?xml version="1.0" encoding="utf-8"?>
        app:srcCompat="@drawable/full_logo" />
        app:srcCompat="@drawable/logo" />

Note: All the attributes of the ImageView which are starting with app:layout_constraint are the vertical and horizontal constraints to fix the image position in the activity. This is very necessary to add the constraint to the ImageView otherwise, all the images will take the position (0, 0) of the activity layout.  

Step 4: Working with the MainActivity file

Go to the MainActivity file and refer to the following code. Below is the code for the MainActivity file. Comments are added inside the code to understand the code in more detail. Since in the activity, only 2 images have been added and nothing else is being done like touching a button, etc. So, the MainActivity file will simply look like the below code. 


import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
    protected void onCreate(Bundle savedInstanceState) {


import android.os.Bundle
class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?)
