Hi Zsolt, sorry for upsetting you. I was just wondering why what I'm trying to work out before was not working.
I also tried your suggestion, I am setting the layout margins programmatically since I have to do some computations first. ImageView pearlImage = new ImageView(this); pearlImage.setImageDrawable(transformedImage); // set onClickListeners, etc. LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); lp.setMargins(100, 100, 0, 0); // test values only but eventually would have to compute for this pearlImage.setLayoutParams(lp); The margins are not being set. I might be missing something in this approach. Thanks, Zarah. On Jun 23, 3:22 pm, Zsolt Vasvari <[email protected]> wrote: > You are just not listening, but doing it your own way.
