I found it easier to navigate to new Activities that extend some
NavigationDrawerActivity base then having one uber-Activity that manages *every
single fragment* from the navigation drawer.

Re: [android-developers] Master Detail Flow with Fragment or Activity

2016-05-31 Thread Amitai Rosenberg 
I see. However, I am already using multiple fragments on the same Activity with 
the Navigation Drawer, like Google suggests. 

One question though: I am trying to implement a shared content element 
transition from my main activity to the details activity. The problem is that 
the content on the first activity is inside a fragment, and calling an intent 
with a shared element transition to the details activity doesn't work.  (If I 
use a fragment for the details this is easier to do). 

Any ideas?
Thanks!

Having one activity manage two fragments on a phone (or small screen
device) adds complexity and responsibility to that Activity. Ideally each
Activity does exactly one thing represented by a screen - either showing a
master list or showing the details of item, in this case.

This also makes it easier to test and re-use. Suppose you want to jump into
an item detail from somewhere other than the master page (deeplinking for
example). If you have the one activity now it has to handle deeplink logic
then bypass the first screen to move to the detail fragment. Then what
happens when you go back? You shouldn't be going back to master (that's
"up"), so now you're jumping through hoops to get the desired behavior.
Keep them separate and life is ultimately easier.

Are you asking why have two activities on phones, each with one fragment,
vs one activity that swaps out two fragments?

[android-developers] Master Detail Flow with Fragment or Activity

2016-05-26 Thread Amitai Rosenberg 


I'm making an Android app from which the user can choose content to read.
There is a list of books, and once the user chooses one, it opens a new 
screen with the content, and a second navigation drawer for navigating 
through the book.


I'm not sure if this screen should be a fragment or an Activity.

I see a lot of recommendations to use fragments, but if you choose a 
Master/Detail Flow template in Android Studio, it creates an *Activity* for 
the details (at least for small screen sizes).

Why is this?

I'd be happy for some guidelines and explanations.

Thanks!
