[Mike1970]

hi everyone

I've to do this also in B4i
Thanks!

Hey @Mike1970.
I presume that if you have to do it in both B4A and B4i, you could probably modify xCLV to do that for you. Yes, you could look at modifying an xCLV layout to hold 2 cards/panels and populating them one at a time for your needs.

You watch Erel answer with a link where he has already done this and I've missed it on the forum lol

Edited: I've just remembered this from guess who lol...

xCustomListView with Four Columns of Imageviews and many Rows

I wanted to accomplish what Erel did in the below link in post #3, but with 4 or multiple columns of imageviews not one imageview column. https://www.b4x.com/android/forum/threads/applying-lazy-loading-to-xcustomlistview-with-imageviews-bitmap-files.101299/ I have a list of bitmap files to show...

Enjoy...

Ouh, interesting!! Thanks!
Later I will take a look!

ok I took a look, and he did like I firstly thought, i've to modify it a bit to catch the _ItemClick event correclty

If the two columns are not aligned then it might be simpler to use two CLVs for this. You can make them scroll together by handling the ScrollChanged event.

Now that's a good idea, actually that's a great idea @Erel.

Seeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee, I knew that was going to happen, I predicted it in an earlier post

See the attached project.

Works quite good. If the user scrolls several lists at the same time then there will be some distortions however they will be resolved quite quickly.

Nice, real nice Erel.
So I tested your ScrollingMultipleCLV with For i = 1 To 1000, it's working extremely smoothly on all three mobile phones that I have in my hand right now in release mode.

Oh yes, it also works perfectly fine on my test iPhone too. I just copied and pasted the code from B4A to B4i and also views in the layout file

Thank you...
