My code: holder.icon.setImageResource(current.imageUrl); here the imageUrl is been declared in String. But setImageResource takes only int. Can anyone provide me a solution how to get a string or is there anyother method available for it?

I think u are fetch the image from internet.

 private Bitmap getBitMapFromUrl( String imageuri){
        HttpURLConnection connection=null;

        try {
            URL url=new URL(imageuri);
            connection= (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream is=connection.getInputStream();
            Bitmap mybitmap=BitmapFactory.decodeStream(is);
            return mybitmap;

        } catch (MalformedURLException e) {
            e.printStackTrace();
            return null;
        }}

pass the string value and return the bitmap.

 holder.icon.setImageBitmap(getBitmapFromUrl());

you are using the "setImageResource" !

it expects a Resource (usually a drawable resource), hence the int requirement.

the download solution suggested by @Mayuri Joshi might fit your needs, if not, please provide more information regarding what it is you are trying to accomplish :)

You have to download the image firstly

public static Bitmap loadBitmap(String url) {
    Bitmap bitmap = null;
    InputStream in = null;
    BufferedOutputStream out = null;

    try {
        in = new BufferedInputStream(new URL(url).openStream(), IO_BUFFER_SIZE);

        final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
        out = new BufferedOutputStream(dataStream, IO_BUFFER_SIZE);
        copy(in, out);
        out.flush();

        final byte[] data = dataStream.toByteArray();
        BitmapFactory.Options options = new BitmapFactory.Options();
        //options.inSampleSize = 1;

        bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,options);
    } catch (IOException e) {
        Log.e(TAG, "Could not load Bitmap from: " + url);
    } finally {
        closeStream(in);
        closeStream(out);
    }

    return bitmap;
}

Then use the Imageview.setImageBitmap to set bitmap into the ImageView
