Xamarin Forms CollectionViews 在 Android 上的性能

Question

The CollectionViews on Xamarin are a really nice feature. Though, I am struggling to get a decent performance, when loading items. And this only happens on Android. It is slow and there is this flickering. Strangely, on iOS it works like a charm.

• The items have a grid, images (~15 Kb), labels buttons, about 9 visual elements
• Text, Images and Commands are bound to viewModel
• I'm using compiled bindings x:DataType=""

I am aware, that bindings are expensive. I've also tried AOT compilation. So, if anyone has some tips..

Thanks!

While you haven't posted any code which makes it possibly for this to happen for any apparent reason, there is just one very likely answer - you are doing too much work on UI thread. That is likely to affect Android much more than iOS because of their different underlying architectures.
