Override Transitions

[GoogleCodeExporter]

I thought it could be cool to have an activity annotation for overriding 
pending transitions like this : 

@Transitions(R.anim.transition_in, R.anim.transition_out)

Generated code:
overridePendingTransition(R.anim.transition_in, R.anim.transition_out);

This would override all pending transitions for the activity but it could also 
be useful on Views.

What do you think ?

http://developer.android.com/reference/android/app/Activity.html#overridePending
Transition(int, int)

Call immediately after one of the flavors of startActivity(Intent) or finish() 
to specify an explicit transition animation to perform next.

This method is to be used on a per need basis. You can call many times in an 
activity life. Where / when would you want to call it ?

Well, I would like to call it anytime the activity invoke a new one or is 
called back.
For now, we have to do this trick ( overridePendingTransition ) each time we 
create a new intent ... 

This code is a repetition and should be specified only once in the activity.
But I agree this feature is not a priority :D

Ok. And what's the idea behing that change ? Why would you want to do that on 
each call to startActivity ?

As I said, that would be better to this only 1 time on the activity : 

@EActivity()
@Transitions(R.anim.transition_in, R.anim.transition_out)

instead of calling this :
overridePendingTransition(R.anim.transition_in, R.anim.transition_out);
each time we open a new intent or get back to the activity.

In some of my activities, I have to duplicate this line up to 10 to 20 times... 
And sometimes, I forget to apply the animations -_-" So the main idea is to 
specify these animations only 1 time, like an activity attribute

Ok, so you would want something like that :

    @Override
    public void startActivity(Intent intent) {
        super.startActivity(intent);
        overridePendingTransition(animIn, animOut);
    }

And this would be for all the startActivity* methods.

Do you usually put the exact same transition in finish(), with the same order 
(animIn / animOut) ? I would think it would be in the reverse order, because 
you are coming back.

What about pressing back in an activity ? Can you also change the animation 
when returning back ?

Actually, I'm not sure if what I'm asking is possible or not... it's not only 
on the startActivity because the overridePendingTransition is available only 1 
time ( for the next activity show / hide ). when the user press back, we must 
override the transition, when there is an activity result. 

Actually, it could also be easier to override the finish() method and add the 
overridePendingTransition() there.

I'm not sure...

I think you should try to implement this in an "Abstract" activity. Once it 
works the way you want in your abstract activity, copy it here and we'll see if 
we can do that in AA.

Since this issue hasn't moved much, I'll close it for now. If you come up with 
a better view of what you want and how to implement it, please post a new issue 
on https://github.com/excilys/androidannotations/issues (maybe a with link to 
this issue)
