Hello Again Im dying for some android screen transitions. I know we there is nothing as fun as IOS transitions, but it would be nice for some android screen transitions. Does anyone out there have any special code snippet for android screen transitions? I love the android screen transition that vertically flips.

Hi @feraco, loads of code snippets on the net, I use a few in the quiz app in my profile. Here's a zoom in/zoom out example: Create a file in your 'anim' folder (in the res folder) called zoom_in.xml and add this code to the file: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/decelerate_interpolator"> <scale android:fromXScale="0.0" android:toXScale="1.0" android:fromYScale="0.0" android:toYScale="1.0" android:pivotX="50%p" android:pivotY="50%p" android:duration="1200" /> </set> Create a zoom_out.xml file too: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/decelerate_interpolator" android:zAdjustment="top"> <scale android:fromXScale="1.0" android:toXScale=".5" android:fromYScale="1.0" android:toYScale=".5" android:pivotX="50%p" android:pivotY="50%p" android:duration="1200" /> <alpha android:fromAlpha="1.0" android:toAlpha="0" android:duration="1200"/> </set> In the activity where you want to use the transition add: overridePendingTransition(R.anim.zoom_in, R.anim.zoom_out) In the onCreate method, just after the layout inflator, so it looks like this: //inflate this screens layout file... LayoutInflater vi = (LayoutInflater)thisActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); thisScreensView = vi.inflate(R.layout.screen_quiz, null); overridePendingTransition(R.anim.zoom_in, R.anim.zoom_out); That's it.

O Great! Im trying this now. Thank you. Where did you find this?

All paths lead from stackoverflow.com lol! I'll get back to you on that. I know there are some examples on the android developer site and there's a compatibility library on github called nineoldandroids for pre-honeycomb animations which is very cool. I'll dig out some links and post back later.

Your the best thank you so much! Ill search to check it out.

haha! no problem @feraco. Here are some links: About animations + some code examples http://developer.android.com/guide/topics/graphics/view-animation.html fade in/fade out http://stackoverflow.com/a/5145226 left to right http://stackoverflow.com/a/5151774 grow from middle/shrink to middle http://stackoverflow.com/a/8570948 The above examples are used the same way as I posted above, nineoldandroids is different but pretty straightforward. http://nineoldandroids.com/ I've got a list of links somewhere, I can't find it... If I do, I'll post it.

Hi feraco, any joy with the transitions?

Yes Those transitions are very nice. right now im using the zoom in zoom out for all screens it works great! I saw an android app that has a really cool screen flip from up to down. but you had to pull it, like a page curl. I dont know how to describe it more than that. Have you seen this?

Excellent! I think I know what you mean, I'm sure I've seen something similar on stackoverflow, haven't tried it though, it looks complicated! Ontouchlisteners and stuff.. I've got a bounce transition that you might like? The screen drops down from the top and bounces a couple of times when it hits the bottom. bounce.xml in the anim folder: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/bounce_interpolator"> <translate android:fromYDelta="-100%p" android:toYDelta="0" android:duration="2000"/> </set> code in the onCreate: overridePendingTransition(R.anim.bounce, R.anim.bounce);

Hey the app is called flipbook for android. Im looking on the stackoverflow now it has a really cool transition.

Here it is http://openaphid.github.io/blog/2012/05/21/how-to-implement-flipboard-animation-on-android/ Im not sure how to implement this.

Not a chance! lol! Just tried now, can't even get the demo running. It's a heck of a lot of code just to flip pages. Would be cool though.. The library's running ok, I'll take a longer look later, but I think it'll take too much modifying of bt screens. In fact, I think it uses fragments which bt don't support yet, although in a few weeks that might have changed.

How do we create screen transitions with the new android core?
