You can use 3rd party http://square.github.io/picasso/

Picasso.with(context).load("imageURL").into(image);

add dependency in Gradle

compile 'com.squareup.picasso:picasso:2.5.2'

You need to get that image from the net.

I recommend you to use Picasso. Add it to your project putting this line into the dependences in your Gradle file:

compile 'com.squareup.picasso:picasso:2.5.2'

And displayed with:

Picasso.with(this).load("URL").into(imageView);

The image is really huge? – MiguelCatalan Feb 04 '16 at 19:24
fullHD or HD, but only 600kb – Marco Ghigo Feb 04 '16 at 19:30
Picasso don't block the ui thread, somthing else is causing you this error. Can you post your code? – MiguelCatalan Feb 05 '16 at 07:49
I add the code in the answer – Marco Ghigo Feb 05 '16 at 16:53
I discovered that one or two imgage are in 4k resolution, and picasso can' t load it. I tried with .resize() but nothing... – Marco Ghigo Feb 05 '16 at 17:08

From an online source? Something along these lines: image.setImageUri(Uri.parse("http://..."))

This is not a good choice, as downloading the image will be done on the main application thread, freezing the UI. – CommonsWare Feb 04 '16 at 17:46

As everyone has mentioned how to use Piccaso , I would like to mention the question is more focused on how to add this ImageView dynamically to the Layout, you can certainlly check the code on github, it's been tested.

LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ImageViewDynamicallyActivity_linear_layout);
// this would be the linear layout to which you can add the `ImageView`

ImageView imageView = new ImageView(this);

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(layoutParams);
// you can make a lot of changes to the `imageview` attributes here
linearLayout.addView(imageView);

Picasso.with(getApplicationContext()).load("http://image.3bmeteo.com/images/newarticles/w_663/immagine-nasa-visible-infrared-imaging-radiometer-suite-viirs-3bmeteo-66721.jpg").into(imageView);

I am assuming you would have added Picasso dependency to your build.gradle file for the app module.

compile 'com.squareup.picasso:picasso:2.5.2'

@MarcoGhigo, i don't think so that using picasso would freeze the UI, I think it takes time to load the image from the URI — Pankaj Nimgade, Feb 05 '16 at 03:52
