Hi All,
This is probably going to be extremely simplistic, but I have an
activity that does some work and is supposed to update the text view
to let the user know where the process is at (some sort of progress
indicator basically). But for some reason none of my textview updates
make it to the screen until the activity has basically completed, by
which time updates are pointless!
After the oncreate of the Activity class I have this ...
TextView tv = new TextView(this);
tv.setText("Starting.");
setContentView(tv);
and then throughout the class at various points (at the moment just
one long procedure .... yeah I know ...) I have ...
tv.setText("Working...");
etc. etc. but none of these appear while it's executing. I've tried
setting invalidate() but that doesn't seem to make it redraw. The
actual procedure itself runs fine (takes about 10-15 seconds). Do I
have to do some fancy threading to update the UI or what?
Cheers,
Tom.
