Why does clicking on one card in RecyclerView open another card?

Question

Android

I have a RecyclerView to which ad cards are added. For example, at the moment 3 (for convenience, let's call them A, B, C) cards in the form of a tape have been added. One and a half cards can fit on the screen at the same time, for example, I click on A - B opens, scrolling through the tape I click on B - C opens. So, how can this be fixed? OnClick is attached to the card and through it I open a new activity, if it matters. This problem is solved only if the card is stretched to full screen, then the desired activity opens, but this solution is not what I need ...

been looking for a click handler for a long time

android:onClick="SelectInfoAd"

they don’t do that, it’s now accepted to process pressing differently. It is necessary to hang up a licener on a view in the code. In the viewholdor, you will have
a very eye-catching code, read the style code, for example, in Java from Google. They don’t write like that in Kotlin, but it doesn’t correspond to Java either. See what hotkey auto-formats the code in the studio
