Hi. I've been having the same problem - working on a card game, and I need to do some actions when the player picks a card. The card may be left face up, or may be turned back over. The problem I was having, as above, was that if I handled all the logic in the onClick(), it didn't display the face of the card, as I'd already flipped it back over before the onClick function finished (which was when the view refreshed).
So... I've moved all the logic about whether the card should stay face-up or flip over again into a separate function, called in a new thread. Brilliant. Almost works great (the card shows its face), but it doesn't quite. For some reason, it's failing on the line ((ImageView) gridview.getChildAt(mIntFirstCardID)).setImageResource (R.drawable.cardback); I've done some debug, and it's finding the gridview object fine, it's finding the child imageview fine, it's finding the drawable ID fine, but it's still bugging out with "...has stopped unexpectedly". Any ideas? Is there some weird property on setImageResource which means I can't call it outside the main thread? Anyone's help would be gratefully received... Thanks!
