Android Question Show/hide a list item on CustomListView with Lazy loading

[toby]

I'm wondering if there is an easy way to show or hide, on the fly, a whole list item, the panel and all child views, on a customListView. Different inputs show different items as user types.

For example, the whole list ( 7 list items in all) is "monday", "tuesday", "wednesday", "thursday", "friday", "saturday", "sunday",

For a list of weekdays containing "t", the list should show: "tuesday", "thursday", "saturday", with 4 items hidden
For a list of weekdays containing "tu", the list should be: "tuesday" and "saturday", with 5 item hidden


Any idea or advice is welcome.

Why use lazy loading with such short list?

You can remove items that you want to hide and later insert them back. You can also call ResizeItem and make them zero sized.

The real list has around 300 items.

The suggestion above will work with lazy loading as well.

What I want is similar to, if not same as, how the B4XSearchTemplate behaves. When each character is entered or deleted, the list shows the filtered result immediately with a smooth transition. Can that be done easily or it requires some expertise?

This link shows an app I downloaded demonstrating similar functionality,

You can also call ResizeItem and make them zero sized.

This sounds a very good suggestion for your goal. You have a searchtext edit box, read the TextChanged event, then go through the xclv setting panel sizes to zero or "standard" depending on the check against the current filter.

Edit: this could be of inspiration too

Thanks to the power of b4x and your valuable helps, implementing the feature is much easier than I originally thought. Attached is a working sample.
