I am writing this tutorial as lot of people are asking me about loading an image into imageview. Just by adding url to ImageView won’t load directly. Instead we need to store the image into cache (temporary location) and attach to ImageView. This can be achieved just by calling couple of lines and don’t forget to add required classes to your project.

Download Code

1. Create a new project in Eclipse IDE by navigating to File ⇒ New ⇒ Android Project and fill the required details.
2. Inorder to load images from an url we first need to store the image in a temporary location and once it is downloaded it should be added to ImageView. To create a temporary file we need to access device external storage. Add required permission to AndroidManifest.xml file.

To access internet required permission is – INTERNET
To access external storage required permission is – WRITE_EXTERNAL_STORAGE

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.androidhive.imagefromurl"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".AndroidLoadImageFromURLActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    
    <!-- Internet Permissions -->
    <uses-permission android:name="android.permission.INTERNET" />
    
    <!-- Permission to write to external storage -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

</manifest>

3. For testing purpose create a simple ImageView in your main.xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Loading image from url"
        android:layout_margin="10dip" />
    
    <ImageView android:id="@+id/image"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_margin="10dip"/>

</LinearLayout>

4. Open your main activity and type the following code. Whenever you wan’t to show an image from url just call the following code.

imgLoader.DisplayImage(image_url, loader, image);
// image_url - is image url path
// loader - loader image, will be shown before loading image
// image - is ImageView
package com.androidhive.imagefromurl;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;

public class AndroidLoadImageFromURLActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        // Loader image - will be shown before loading image
        int loader = R.drawable.loader;
        
        // Imageview to show
        ImageView image = (ImageView) findViewById(R.id.image);
        
        // Image url
        String image_url = "https://api.androidhive.info/images/sample.jpg";
        
        // ImageLoader class instance
        ImageLoader imgLoader = new ImageLoader(getApplicationContext());
        
        // whenever you want to load an image from url
        // call DisplayImage function
        // url - image url to load
        // loader - loader image, will be displayed before getting image
        // image - ImageView 
        imgLoader.DisplayImage(image_url, loader, image);
    }
}

5. Add following classes in your project and run the project.

    realy thanks man… works fine…

  • David Dimalanta

    There is a problem with the ImageLoader class. You see, when I added the BitmapFactory.Options o2 under decodeFile(File f) method, I get an “Unreachable Code” error status. What should I do?

  • Smart guy

    no image will be show only loader image is shown help me whats the problem

  • David Dimalanta

    Raise the REQUIRED_SIZE.

  • David Dimalanta

    This tutorial is the worst! It is due by updates, instead of the image loaded properly from the URL, I got corrupted image as a result. Look at my sample.

  • Udhay

    Reading image from URL can be performed inside AsynTask as it should not affect the current Activity. Using AysnTask will run downloading image from URL as separate thread.

    • chemechaos

      I had a similar problem. The imageview id in your layout file isn’t matching with the declaration in your activity, or you shouldn’t put int but loader inside setImageResource,

  • chemechaos

    Because I needed to reload the image every time my app loaded, I added clearCache(); before queuePhoto(url, imageView);

        • Anish Panthi

          Sorry for the late reply. use the following code:

          private Bitmap decodeFile(File f) {
          try {
          // //decode with inSampleSize
          BitmapFactory.Options o2 = new BitmapFactory.Options();
          // o2.inSampleSize=scale;
          return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
          } catch (FileNotFoundException e) {
          }
          return null;
          }

    • Kamran Ahmed Ansari

      The reference of the ImageView you passed into the ImageLoader class points to null. In simple words, check your findViewById(R.id.image) part of the code. It must be returning null.
