I'm not sure what your code looks like, but some things you could try
are:
1) If you are using a thread to do all of the network calls, maybe
have something like
while(!pageIsDone) {
sleep(1000);
}
// then display data
And in your Activity class you can set the boolean pageIsDone to true
as soon as the necessary views have been loaded? Definitely probably
not the "preferred" way to do it though...
2) The "no thinker" way to do it would probably just be to start the
background thread after your UI display is done loading. I think this
is typically acceptable as your application will not timeout / ANR and
your user will not experience in "lag" in their experience of your
app. Note this can often be paired with some sort of progress dialog
to make it even "better"
Not sure if this will help but maybe its a start?
