Create An Android ImageView Programmatically in Kotlin

Hello Readers! In this post, we are going to learn about how to use android imageView programmatically in kotlin in the application. We will also learn how to add imageView to linearLayout programmatically in android application.

Getting Started

At first, we will create android project. Then, we will create and use imageView programmatically in kotlin file.

1. Creating New Project in Kotlin

Follow the steps below to create new project. Please ignore the steps if you have already created a new project.

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as DynamicImageView. Then, check Include Kotlin Support and click next button.
3. Select minimum SDK you need. However, we have selected 17 as minimum SDK. Then, click next button
4. Then, select Empty Activity => click next => click finish.
5. At this point, You will get a newly created android project successfully.

Now, we will modify xml and kotlin file to use imageView dynamically.

2. Modify Values Folder

No values folders have been modified. So, we are not going to mention them here.

3. Modify Layout Folder

Open res/layout/activity_main.xml file. Then, add below code into it.

<?xml version="1.0" encoding="utf-8"?>

		android:text="Change Image"/>


In activity_main.xml file, we have defined linearLayout and button widget. LinearLayout, with id rootContainer, will also act as container for the imageView created programmatically in the application.

4. Create Android ImageView Programmatically / Dynamically in Kotlin

Open app/src/main/java/com.tutorialwing.dynamicimageview/MainActivity.kt file. Then, add below code into it.

package com.tutorialwing.dynamicimageview

import android.os.Bundle
import android.widget.Button
import android.widget.ImageView
import android.widget.LinearLayout

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {

        val imageView = ImageView(this)
        imageView.layoutParams = LinearLayout.LayoutParams(160, 160) // value is in pixels

        val imgResId = R.drawable.ic_launcher_background
        var resId = imgResId

        val button = findViewById<Button>(
        button?.setOnClickListener {
            resId = if (resId == R.drawable.ic_launcher_background) R.mipmap.ic_launcher else R.drawable.ic_launcher_background

        val linearLayout = findViewById<LinearLayout>(
        // Add ImageView to LinearLayout

We have created imageView programmatically in kotlin file (i.e. MainActivity.kt) in the application. After that, we have set layout params, image resource in it. Then, we have set click listener on button to change the image in imageView whenever button is clicked.

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml file

Code inside src/main/AndroidManifest.xml file is –

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.dynamicimageview"

		<activity android:name=".MainActivity">
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>


When we run the program, we will get output as shown above.

That’s end of our tutorial on Creating Android ImageView Programmatically in Kotlin.
