    This is due to the size of the image and due to processing it mainly in the UI stream. The solution is to reduce the picture and / or display it asynchronously.

    The latter can be done using either to display images - UIL or Picasso.

    • Unfortunately, Picasso cannot cope with such a problem, I compressed the image to a more acceptable quality. - Evgeny Suetin
    • @YevgeniySuyetin, I didn’t quite understand what you mean, but after I displayed the pictures as UIL, lags in ScrollView disappeared. - Yuriy SPb ♦
    • Unfortunately, when there was a picture of good quality, then the lags did not disappear, the amount of allocated RAM was about 200mb and it saw 1 picture on the screen - Evgeny Suetin
    • @ YevgenySuyetin, what if UIL is th? .. Are you talking about Picasso? - Yuriy SPb ♦
    • When I started using UIL, I had already applied compression, so it wasn’t possible to check. - Eugene Suetin
