Loading Image From URL Into Imageview

Question

I'm trying to use the image from this url: http://www.bisonsoftware.us/hhs/image/1.png

I want to take this image and set it in a imageview, I'm just looking for the easiest way to do this.

I tried this solution but it seemed to not work for me, it gave an error saying malformedurlexception: Load image from url

Answer 1

Use the universal image library:

After adding this library with your project. write this code on necessary place

ImageLoader imageloader;
DisplayImageOptions options;
imageloader = ImageLoader.getInstance();
        String url="http://www.bisonsoftware.us/hhs/image/1.png";
        imageloader.init(ImageLoaderConfiguration.createDefault(getApplicationContext()));
        options = new DisplayImageOptions.Builder()
                .showImageForEmptyUri(R.drawable.ic_empty)
                .showImageOnFail(R.drawable.ic_error)
                .resetViewBeforeLoading(true).cacheOnDisk(true)
                .imageScaleType(ImageScaleType.EXACTLY)
                .bitmapConfig(Bitmap.Config.RGB_565).considerExifParams(true)
                .displayer(new FadeInBitmapDisplayer(300)).build();

imageloader.displayImage(url,imageview);

Try to implement like this. Its working for me for download image from url. And also don't forget to add Internet permission in manifest file,like this-<uses-permission android:name="android.permission.INTERNET"/>

import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;

import android.app.Activity;
import android.app.ProgressDialog;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;
import android.os.Bundle;
import android.widget.ImageView;

public class MainActivity extends Activity {
ProgressDialog progressDialog;
ImageView imageView;
Bitmap map = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    imageView = (ImageView) findViewById(R.id.imageView);
    new loadImage().execute();
}

public class loadImage extends AsyncTask<Void, Void, Void> {

    @Override
    protected void onPreExecute() {

        progressDialog = new ProgressDialog(MainActivity.this);
        progressDialog.setMessage("Please wait...");
        progressDialog.setCancelable(false);
        progressDialog.show();

    }

    @Override
    protected Void doInBackground(Void... params) {

        map = downloadImage("http://www.bisonsoftware.us/hhs/image/1.png");

        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        progressDialog.dismiss();
        imageView.setImageBitmap(map);
    }
}

// Creates Bitmap from InputStream and returns it
private Bitmap downloadImage(String url) {
    Bitmap bitmap = null;
    InputStream stream = null;
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inSampleSize = 1;

    try {
        stream = getHttpConnection(url);
        bitmap = BitmapFactory.decodeStream(stream, null, bmOptions);
        stream.close();
    } catch (Exception e1) {
        e1.printStackTrace();
    }
    return bitmap;
}

// Makes HttpURLConnection and returns InputStream
private InputStream getHttpConnection(String urlString) throws IOException {
    InputStream stream = null;
    URL url = new URL(urlString);
    URLConnection connection = url.openConnection();

    try {
        HttpURLConnection httpConnection = (HttpURLConnection) connection;
        httpConnection.setRequestMethod("GET");
        httpConnection.connect();
        if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
            stream = httpConnection.getInputStream();
        }
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return stream;
}

@Override
public void onDestroy() {
    super.onDestroy();
    if (progressDialog != null && progressDialog.isShowing()) {
        progressDialog.cancel();
    }
}

@Override
protected void onStop() {
    super.onStop();
    if (progressDialog != null) {
        progressDialog.dismiss();
        progressDialog = null;
    }
}  
}

Happy Coding :)

public class MainActivity extends Activity {

private Bitmap bitmap;
private ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    imageView=(ImageView)findViewById(R.id.imageView1);
    new downloadimage().execute();
}
private class downloadimage extends AsyncTask<Void, Void, Void>
{

    @Override
    protected Void doInBackground(Void... params) {
        URL url;
        try {
            url = new URL("http://www.bisonsoftware.us/hhs/image/1.png");
            bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());


        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


        return null;
    }
    @Override
    protected void onPostExecute(Void result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        imageView.setImageBitmap(bitmap);
    }
}
}

This is working for me.

If you just want to use native android code, you can download it using AsyncTask and then set it in onPostExecute.

Call it as:

//pass image view while creating AskyncTask object and pass url as parameter
new DownloadImageTask((ImageView) findViewById(R.id.yourImageView)).execute("your_url_here");

AsynTask to call:

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
    }
}

I just saw that a similar answer is also mentioned in the url which you've mentioned in the question. This is working for my app. If its gives MalformedUrlException, then you can try checking if url is proper and if needed encode it properly.

Answer 5

You can do it the hard way like Shobhit described, or there's a library that does the same thing(creates another thread to render the image) for you such as the aforementioned picasso or UniversalImageLoader: https://github.com/nostra13/Android-Universal-Image-Loader

Answer 6

Use the Picasso library https://square.github.io/picasso/

It would be just like this:

Picasso.with(context).load("http://www.bisonsoftware.us/hhs/image/1.png").into(imageView);
