ImageView in Android using Jetpack Compose
Last Updated : 20 Feb, 2025
Images, graphics, and vectors attract many users as they provide a lot of information in a very informative way. ImageView in Android is used to display different types of images, from drawables to Bitmaps. In this article, we will take a look at the implementation of an ImageView in Android using Jetpack Compose.
Attributes of ImageView Widget
Attributes | Description |
|---|
| painter | the painter resource used to draw the image. Here, painterResource is used to load an image from the resources. |
| bitmap | to add a bitmap for your image inside imageview. |
| modifier | to add padding to imageview |
| contentScale | to add scaling to our image to fit our image inside imageview |
| alpha | to add alpha to our imageview. |
| colorFilter | to add colors to our imageview. |
| blendMode | to add color effects to our imageview. |
contentDescription | to describe the content of the image for accessibility. |
alignment | to align the content within the bounds of the Image |
Step-by-Step Implementation
Step 1: Create a New Project
To create a new project in the Android Studio Canary Version please refer to How to Create a new Project in Android Studio Canary Version with Jetpack Compose.
Step 2: Add an Image to the drawable folder
After creating a new project we have to add an image inside our drawable folder for displaying that image inside our ImageView. Copy your image from your folder's location and go inside our project. Inside our project Navigate to the app > res > drawable > Right-click on the drawable folder and paste your image there.
Step 3: Working with the MainActivity.kt file
After adding this image navigates to the app > java > MainActivity.kt and add the below code to it. Comments are added inside the code for a detailed explanation.
MainActivity.kt:
MainActivity.kt package org.geeksforgeeks.demo import android.os.Bundle import androidx.activity.ComponentActivity import androidx.activity.compose.setContent import androidx.activity.enableEdgeToEdge import androidx.compose.foundation.* import androidx.compose.foundation.layout.* import androidx.compose.foundation.shape.CircleShape import androidx.compose.material3.* import androidx.compose.runtime.Composable import androidx.compose.ui.* import androidx.compose.ui.graphics.* import androidx.compose.ui.layout.ContentScale import androidx.compose.ui.res.painterResource import androidx.compose.ui.tooling.preview.Preview import androidx.compose.ui.unit.dp import org.geeksforgeeks.demo.ui.theme.DemoTheme class MainActivity : ComponentActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) enableEdgeToEdge() setContent { DemoTheme { // A surface container using the // 'background' color from the theme Surface( // to add background color for our screen. color = MaterialTheme.colorScheme.background, ) { // at below line we are calling // our function for image view. ImageExample() } } } } } @Composable fun ImageExample() { Column( // we are using column to align our // imageview to center of the screen. modifier = Modifier .fillMaxWidth() .fillMaxHeight(), // below line is used for specifying // vertical arrangement. verticalArrangement = Arrangement.Center, // below line is used for specifying // horizontal arrangement. horizontalAlignment = Alignment.CenterHorizontally, ) { // below line is used for creating a variable // for our image resource file. val painter = painterResource(id = R.drawable.gfg_logo) // below is the composable for image. Image( // first parameter of our Image // is our image path which we have created // above painter = painter, contentDescription = "Sample Image", // below line is used for creating a modifier for our image // which includes image size, padding and border modifier = Modifier .height(300.dp) .width(300.dp) .padding(16.dp) .border(2.dp, Color.Black, CircleShape), // below line is used to give // alignment to our image view. alignment = Alignment.Center, // below line is used to scale our image // we are using fit for it. contentScale = ContentScale.Fit, // below line is used to define the opacity of the image. // Here, it is set to the default alpha value, DefaultAlpha. alpha = DefaultAlpha, ) } } // @Preview function is use to see preview // for our composable function in preview section. @Preview(showSystemUi = true) @Composable fun ImageExamplePreview() { // we are passing our composable // function to display its preview. ImageExample() } Output:
