B4A Library Wrapper for KenBurnsView - an animated ImageView

Inman · Mar 26, 2014

Ken Burns Effect is a visual effect developed by director Ken Burns to animate photos, mostly in documentaries.

Now there is an ImageView available for Android called KenBurnsView that allows us to use this effect

https://github.com/flavioarfaria/KenBurnsView

Please develop a wrapper for this ImageView

I'm using B4A V4 and have added the library to my libraries, restarted the IDE however, the library does not get listed on CustomType, please see attachment. Can you please help on me to get this to work?

Thanks

Erel · Jan 6, 2015

You don't need to restart the IDE. You can right click on the libraries list and choose Refresh.

Have you checked the library in the libraries list?

I can't see the views in front of the kenburnsview, seems like it won't sendtoback...
Is there a way around this?

Erel · May 26, 2015

Yes. Put it in a panel and add the other views above this panel (not as children of this panel).

@Erel, also is there a way to skip the first transition (since it starts in the top-left corner and takes a while to get to the middle of the image...

Erel · Jun 9, 2015

No. You can't change the transition.

The image is shown and kenburn effect is displayed... after few seconds... CRASH!

Looks like theme cause the crash.

B4X:

SetApplicationAttribute(android:theme, "@android:style/Theme.Holo.NoActionBar.TranslucentDecor")

With Holo works ok...

B4X:

SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")

I've used this thread to fix my problem... i don't know if this is the best way:

B4X:
