Android Question Filter a list

[deyvitm]

As I can do this in BA4, filter a list ??

List<"NameObjec"> newList = List.FindAll(s => s.Campo1 == "valo1" && s.Campo2 == "valor2");

Thx

No.

You need to create a sub which do the search for you and then return a new list with the results of the filtering.

And there will be an example of good practice for this type of search ?, to be an optimal search, please??

Maybe it is better to do the search when reading the values fro a database.

The routine will be fast if it is just a few (hundrets) of items in the list.

Where does the content from the list come from? A Database?

My data comes from json webservice response, then I keep them in a list, which must filter combobox to fill in the entire application and unfortunately the webservice brings all the data in general

Something like this @deyvitm https://www.b4x.com/android/forum/threads/class-searchview.48576/#content. Changing the example in the link to work from a JSON feed should be easy enough using the information provided on this great community...
