How to Display Image From Image File Path in Android using Jetpack Compose?
ImageViews are used to display images in different formats within the Android Application. We can display images within our Image View from the image file name, bitmap, drawable file, and the image URL as well. In this article, we will take a look at How to load images from user devices within Image View using the image path within our Android Application using Jetpack Compose.
Step by Step Implementation
Step 1: Create a New Project in Android Studio
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. While choosing the template, select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version. We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project.
Step 2: Working with the MainActivity.kt file
Go to the MainActivity.kt file and refer to the following code. Below is the code for the MainActivity.kt file. Comments are added inside the code to understand the code in more detail.
Kotlin

Column( // on below line we are adding padding // padding for our column and filling the max size. Modifier .fillMaxSize() .fillMaxHeight() .fillMaxWidth(), // on below line we are adding // horizontal alignment for our column horizontalAlignment = Alignment.CenterHorizontally, // on below line we are adding // vertical arrangement for our column verticalArrangement = Arrangement.Center ) { Text( // on below line we are specifying text to display. text = "Image from File Path in Android" , // on below line we are specifying // modifier to fill max width. modifier = Modifier .fillMaxWidth() .padding( 20 .dp), // on below line we are // specifying text alignment. textAlign = TextAlign.Center, // on below line we are // specifying color for our text. color = Color.Black, // on below line we are // specifying font weight fontWeight = FontWeight.Bold, // on below line we // are updating font size. fontSize = 25 .sp, ) // on below line we are creating an image file and // specifying path for the image file on below line. val imgFile = File( "/storage/emulated/0/Download/GeekforBeginnerphoto.png" ) // on below line we are checking if the image file exist or not. var imgBitmap: Bitmap? = null if (imgFile.exists()) { // on below line we are creating an image bitmap variable // and adding a bitmap to it from image file. imgBitmap = BitmapFactory.decodeFile(imgFile.absolutePath) } Image( // on the below line we are specifying the drawable image for our image. // painter = painterResource(id = courseList[it].languageImg), painter = rememberImagePainter(data = imgBitmap), // on the below line we are specifying // content description for our image contentDescription = "Image" , // on the below line we are setting the height // and width for our image. modifier = Modifier .fillMaxWidth() .height( 200 .dp) .padding( 10 .dp) ) } } |
Now run our project to see the output of the application.
