[android-developers] Re: Loading random image when activity is brought up...Not working any ideas?
If you could send the src project, it would be wonderful.
Still, i feel setTag isn't a good option, you should use
setImageDrawable with drawable object.
I would have used setImageResource(q) to change the image inside the
onClick function of the button.
for that, the ImageView needs to be accessible inside onClick too.
I don't think there's a need to refresh the activity, you can change
the image without restarting the whole activity
Also, just try to see what random number or Random() class's object is
giving.
I have seen many times that it generates same integer every time if
the limit (0-max) is short.
check this too.
for LogCat, what i do is i print messages from my code using
System.out.println() and have created a filter in LogCat which
separates all the output tagged with System.out
it helps me, maybe it can help you too, to find out what ur code is
doing at times.
Enjoy.

peace of mind. Looking at it I see nothing wrong. Neither does

Lets just forget about the button, say i literally did just want a
different image to come up whenever the page was visited. Anyone see
the error? This has been bugging me for days.

Perhaps you should just look at finding (findViewById()) the ImageView
and assigning it to a member field (you're currently finding it and
assigning it on the stack), then in your onClick() override just do
mMyImageView.setImageDrawable() (or whatever) to re-set what the
rendered image should be?
