B4i Library [class] SearchView

This class is similar to B4A SearchView class. It allows the user to filter a list of items based on a term (prefix matches first followed by other matches).

It uses the new RichString class to highlight the matching terms. Note that the scrolling and filtering performance in release mode are very good. It can be a bit jumpy in debug mode.


New version of SearchView is now available. It is implemented as a custom view. It also properly handles the keyboard state.

Is it possible to add an item with more than just one line? I believe with the equivalent in B4A you can add singleline and doubleline. Is it possible to add a custom view or something (i.e., an entry with a line and an icon?)

 

[Erel]

Edit CustomListView.SetCache and set lbl.Multiline = True.

You can further customize it with any view you like.

Erel, thank you very much!

How do I put default text on it
there is no sv.text = "something"

and second question, how do I do sv2.enabled = false
since I want to enable it only after sv1.text has something in it
(sv1 = cities, sv2 = streets)
I wish to load only the relevant streets by city

 

[Erel]

Go over the code, most of it is not too complicated and change it in any way you like.

 

[Erel]

I've uploaded a new version of SearchView that is based on TableView instead of CustomListView. This change simplifies the code and improves the performance (in the previous implementation there were caches and two steps loading that now are not required).

I am getting error that my IDE is older (I am using 1.80)

 

[Erel]

Please ignore it. Currently the latest version is 1.80 and it should work fine with this project.

Erel,

Is there any way to add a border to searchview

 

[Erel]

Yes, add lv.SetBorder or et.SetBorder in the Initialize sub.

 

[kemanlam]

where is the "cities.txt" files in the zip file?

 

[Erel]

It should be in the Files folder.

I have updated Erel's SearchView with using the iOS native SearchViewController (like in iMessage, Whatsapp, Viber,...)

It is just the basic wrapping so you can contribute to it.

For current users of SearchView you do not need modify anything in your code.

Project attached.

Very nice!

Can this program operate against a "csv" file?

 

[Erel]

You need to create a List with the strings that should go to the SearchView. The data can come from any source you like including CSV (use StringUtils.LoadCSV).

This works very well on most text files. However I have 271 "Div/state" files...the entire list of cities
in the world. The 3 one I tested is "UK.TXT" which is a simple ascii list of the cities in the UK.
I get "encode-error" when I try to open it:"Error reading file. Incorrect encoding"

I have checked the file and can not find any weird letters?

 

[John Woodsmall]

In the "New" from:"narek-adonts" search view above (which I have added to my app) it does not seem to return a value to
the sv_ItemClick(Value As String)
.
On the first one (above) it works correctly. But on the new one which looks great(i would love to use it)
it does not seem to return a value. All i did was replace the new *.bas to my app.

Open the file with Notepad++ and change its encoding to UTF8:

However this file is too large for SearchView to index. It will probably be quite slow.
