ArrayListObservable.onDisplay / onHide

[Chris Blume]

I looks like the current release and even early build of v0.6 doesn't have onDisplay and onHide in ArrayListObservable.

I don't see it in master: https://github.com/gueei/AndroidBinding/blob/master/Core/AndroidBinding/src/gueei/binding/collections/ArrayListObservable.java

I also don't see it in the develop branch: https://github.com/gueei/AndroidBinding/blob/develop/Core/AndroidBinding/src/gueei/binding/collections/ArrayListObservable.java

But it looks like it was available in the v0.4 branch? https://code.google.com/p/android-binding/source/browse/branches/v0.4/AndroidBinding/src/gueei/binding/collections/ArrayListObservable.java?r=361

I ask because I seem to be running into a memory problem where scrolling through an infinite list is loading too many bitmaps (one per row) and my app crashes with an out-of-memory error. I think I should cache the bitmap to flash and unload the bitmaps from main memory when hidden. Or maybe when too far away from the visible range. But I can't seem to get onDisplay and onHide...

Thanks!

Hi,

Please refer to other thread about memory issue:

https://groups.google.com/forum/#!topic/androidbinding/nIO2EbgUIf4

The hide/display/onLoad is not handled in ArrayListObservable, but in the Adapter: https://github.com/gueei/AndroidBinding/blob/master/Core/AndroidBinding/src/gueei/binding/collections/CollectionAdapter.java

It's there in v0.6, don't worry. ICSDemo is using it too.
