Android - loading a big Activity

Question

I am running an activity from another one but I have to inflate like 200 views so it takes 3-4 seconds to start. How do you recommend me to do? Should I make a loading screen? If yes, how hould I do that?

EDIT: is it possible to load the onCreate() of an activity at the beggining of the app and show the activity later ?

This guy here had the same problems. Just take a look: http://stackoverflow.com/questions/8179092/how-to-show-splash-image-while-loading-activity — weletonne, Aug 20 '15 at 08:48
No I will not share my app on internet. I want to publish my app. I have a simple xml with 3 or 4 views and then I inflate it 150 times more or less with a row that has one textview and 2 checkboxes — Roman Panaget, Aug 20 '15 at 09:36

Yes you should make a loading screen, 3-4 seconds are too long for a user to wait without a loading screen (most will think app is frozen and kill it).

You can try this:

put you interface into a fragment instead activity
load blank activity with setContentView()
launch a ProgressDialog or something else
inflate the fragment
when inflating is finished, display the fragmetn in the activity and dismiss the dialog

You can't use a dialog while executing setContenView() – Roman Panaget Aug 20 '15 at 09:02
My bad, the "inflate" made me think he was using a fragment in the second activity. – Damien Belard Aug 20 '15 at 09:05
And how should I know when the loading has finished? – Roman Panaget Aug 20 '15 at 09:19
