When user clicks a button, these 3 lines are executed: button = new ImageButton(context); button .setImageResource(R.drawable.buttonJPG); layout.addView(button, new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
I observe that during the first add, it takes about 3.5 seconds. Subsequent adds are much quicker at about 0.5 sec. On actual devices, it will be many times slower. thanks, Anil On Apr 3, 6:29 pm, "Romain Guy" <[EMAIL PROTECTED]> wrote: > I highly doubt this number since during a scroll, ListView basically > adds and removes Views all the time.
