Problem with pressed Button in AndroidStudio. I want to hold down on an imageview-button and drag it to an specific location, which should open afterwards an activity

[Zererat]

Honestly I dont know how to proceed. I looked up some feeds on this website and on stackoverflow got a bit confused and dont know how to get it done. The imageview button should be dragged (while holding it down) at a specific location of an other imageview and as long as my pressed thumb relocates to the other image, a activity should be called. In an earlier version, the activity was functional but not while moving the button while it was held down by my thumb. Hopefully someone knows an answer for this (for me a very challenging question.)
