How do I load an Image by URL using Picasso Library on Kotlin?

This example demonstrates how to create a WebView in an Android App using Kotlin.

Step 1 − Create a new project in Android Studio, go to File ? New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

Example

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:paddingStart="16dp"    android:paddingTop="16dp"    android:paddingEnd="16dp"    tools:context=".MainActivity">    <TextView       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:text="Load ImageView by URL"       android:textColor="@color/colorPrimary"       android:textSize="20sp"       android:textStyle="bold" />    <ImageView       android:id="@+id/image_view"       android:layout_width="fill_parent"       android:layout_height="300dp"       android:layout_marginTop="16dp" />    <TextView       android:layout_width="fill_parent"       android:layout_height="match_parent"       android:gravity="center|bottom"       android:textSize="24sp"       android:textStyle="bold" /> </LinearLayout>

Step 3 − Add the following dependency to build.gradle(Module:app)

implementation 'com.squareup.picasso:picasso:2.5.2'

Step 4 − Add the following code to src/MainActivity.kt

Example

import android.os.Bundle import android.widget.ImageView import androidx.appcompat.app.AppCompatActivity import com.squareup.picasso.Picasso class MainActivity : AppCompatActivity() {    override fun onCreate(savedInstanceState: Bundle?) {       super.onCreate(savedInstanceState)       setContentView(R.layout.activity_main)       title = "KotlinApp"       val imageView: ImageView = findViewById(R.id.image_view)       val url = "https://cdn.pixabay.com/photo/2018/01/14/23/12/nature-3082832__340.jpg"       Picasso.with(this).load(url).into(imageView)    } }

Step 5 − Add the following code to androidManifest.xml

Example

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.myapplication">    <application       android:allowBackup="true"       android:icon="@mipmap/ic_launcher"       android:label="@string/app_name"       android:roundIcon="@mipmap/ic_launcher_round"       android:supportsRtl="true"       android:theme="@style/AppTheme">       <activity android:name=".MainActivity">          <intent-filter>             <action android:name="android.intent.action.MAIN" />             <category android:name="android.intent.category.LAUNCHER" />          </intent-filter>       </activity>    </application> </manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen
