How to load an ImageView by URL in Android?

You'll 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
