Can't load image from raw to imageview

I want to load image using setImageResource, from raw folder to imageview, But I get Expected resource of type drawable error.

I'm using android studio, Before that when I was using Eclipse everything was fine. I don't want to use drawable folder.

You can try it 

   InputStream imageStream = this.getResources().openRawResource(R.raw.name);
   Bitmap bitmap = BitmapFactory.decodeStream(imageStream);
   imageview.setImageBitmap(bitmap);

Using a raw resource for setImageResource() is not documented behavior.

Not really. While your code runs, it might not on all past, present, and future versions of Android. This is why there is a compiler warning.

because drawable scaled down images depend of device

Use drawable-nodpi for drawables that should not be scaled based upon screen density. That is usually not a good idea, but perhaps you have a reason for it.

A safer approach for using a raw resource would be to use openRawResource() on Resources to get an InputStream, then use BitmapFactory to read in the bitmap.

You are welcome to suppress the warning with @SuppressWarnings("ResourceType"), but do not complain when your app stops working.
