I am developing a chat app, and when I open a chat with images (that I am loading using Fresco), it scrolls automatically. Initially, I was using Picasso for loading image, but I tried changing it with other libraries, but the issue remained same. Can anyone guide me what could be the issue or what is the right direction to fix the issue?

Are you sure this is related to Fresco? Just try to remove image inflating (don't set image url) and if you have the same issue. – Ihor Bykov Oct 10 '18 at 19:11

@zohad check in your code where you call `scrollToPosition` – Ihor Bykov Oct 10 '18 at 19:24

Not in adapter, Do you interact with Layout manager to scroll? – Ihor Bykov Oct 10 '18 at 19:27

Try this call
recyclerView.scrollToPosition(yourListMessages.size() - 1);
It will set to bottom of your list of messages

To avoid this issue, either use image placeholders while an image is loading or establish a minimum size for your cell that's close to the size of the image once it's loaded. It looks your cell is re-sized to fit the image when loading is done, causing rest of the content in your recycler view to shift to accommodate new cell size.
Another thing to try is to set a defined height on your ImageView and use any of the options from android:scaleType to match how you display an image in your cell based on your needs.

Well now that you know what the issue is, I am sure you will find a way to deal with it. I have no idea of your business requirements to suggest any more solutions. – C0D3LIC1OU5 Oct 10 '18 at 19:30

@zohaibkhaliq If any of these answers helped you, you should upvote/accept it. – C0D3LIC1OU5 Oct 15 '18 at 19:20

@zohaibkhaliq You should post the solution you found as a separate answer if it's different from any of the answers here. This way people who have the same issues will be able to resolve them, – C0D3LIC1OU5 Oct 15 '18 at 21:27

Delayed the call to scrollToPosition until recycler view item gets loaded.

This looks like a workaround. List cells shouldn't resize once an image is loaded. – C0D3LIC1OU5 Oct 16 '18 at 21:10
