I not sure how to word this for a search, I have been trying. What I want to do is have a image view that moves with user touch. Basically you touch the image/label and it moves with your finger until release.

I did view this but this seems only capable of zoom/resize the image. I wish to move/drag the image wherever the user's finger is until it is released.

You are looking drag function if I understand

Here in this post is example of label. When you press and drag a label all over the screen.
Drag a label example

It will be easy for you to make it to drag a image.

TouchImageView can do exactly what you want.

You can set it's Bitmap property - pass a Bitmap.
Then set both MinScale and MaxScale to 1 and you'll have a draggable Bitmap which cannot be zoomed in or out.

You can see from that post that someone else also wanted a draggable but not zoomable version.
I shall make time to update the library and either add an option to disable zooming or create a new draggable but not zoomable library.

The attached sounds like what you are looking for. It doesn't use any external libraries.

I found this in my B4A folder, but I don't remember where it came from and I couldn't find it on here by searching. Maybe whoever wrote it will recognize it and claim it.

Thanks for thnx for the examples!

I am toying around with which I can use in a game and be interactive with another layer or a position on the screen.

This will get me started in the right direction. I know what I'm attempting is probably not difficult to the experts here, but I'll learn a lot trying to get this done. :sign0104:
