Activity transition in Android?

You can do this with Activity. OverridePendingTransition(). You can define simple transition animations in an XML resource file.

A good tutorial on this can be found here.

Thanks iandisme. OverridePengingTransition is API level 5. Is it not possible to do this for level 3 (Android 1.5)?

Yes. You can tell the OS what kind of transition you want to have for your activity. @Override public void onCreate(Bundle savedInstanceState) { super.

OnCreate(savedInstanceState); getWindow(). SetWindowAnimations(ANIMATION); ... } Where ANIMATION is an integer referring to a built in animation in the OS.

GetWindow(). SetWindowAnimations(android.R.anim. Fade_in) doesn't result in the push transition that was used by default, but it's not a fade transition either.

The new activity just appears over the previous one in a Nexus One device. – hgpc Aug 2 '10 at 16:33 1 That's because this isn't asking for a resource, it's asking for the id of a transition animation built into the OS.Developer.android.Com/intl/fr/reference/android/view/…) – CaseyB Aug 2 '10 at 16:43 Can you provide an example? I can't find the constant.Thanks.

– hgpc Aug 2 '10 at 17:11 1 It seems setWindowAnimations only accepts style resources.GetWindow(). SetWindowAnimations(android.R.style. Animation_Toast) is the closest I've found to a fade in, but it fades from black, not the previous activity.

– hgpc Aug 2 '10 at 17:48 It doesn't have to be built in animation in the OS, you can definite a custom one in values. – ilija139 Aug 5 at 12:17.

Here's the code to do a nice smooth fade between two Activities.. Create a file called fadein. Xml in res/anim Create a file called fadeout. Xml in res/anim If you want to fade from Activity A to Activity B, put the following in the onCreate method for Activity B.

Before setContentView works for me. OverridePendingTransition(R.anim. Fadein, R.anim.

Fadeout); If the fades are too slow for you, change android:duration in the xml files above to something smaller.

4 Just to add to this. OverridePendingTransition() will need to be called again, right after the OS decides to close your Activity. I just put another identical call to overridePendingTransition(fadein,fadeout) in the Activity's onPause() method.

Otherwise, you'll see the Activity fade in, but not fade out when closed. – Nate Aug 24 at 1:10.

You cannot use overridePendingTransition in Android 1.5. OverridePendingTransistion came to Android 2.0. If you're gonna go through this without any error you have to compile for the target (1.5 or higher) using the ordinary animations (or you own) or you have to compile for the target (2.0 or higher) using overridePendingTransistion. Summary: You cannot use overridePendingTransistion in Android 1.5. You can though use the built-in animations in the OS.

That is not correct. Animations are in Android well before 1.6 and you can use overridePendingTransistion with reflection to still target 1.5. – hgpc Aug 2 '10 at 17:46 Well, my mistake. Updated my post.

You can surely do your own animations and customizing them as you want in 1.5. But you can still not use overridePendingTransition since it started to appear in API-level 5. – Julian Assange Aug 2 '10 at 17:57.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
