B4A Library [Class] SearchView - More powerful alternative to AutoCompleteEditText

Erel · Jul 8, 2012

Edit: better to use B4XDialog + B4XSearchTemplate

SearchView is made of an EditText and ListView. When the user enters text into the EditText the ListView shows the items that start with this text or that contain the text (in this order).

This view is useful for allowing the user to select an item from many items.

Advantages over AutoCompleteEditText:

SearchView uses an internal index that is built when you call SetItems. This allows it to quickly find the matches.
SearchView also shows items that contain the input text (not just prefixes).
The class code can be further customized as needed.

Please start a new thread for this question.

There are two parts in code, that seems make no effect, if I comment them out.

1) in manifest-Editor

B4X:

SetActivityAttribute(main, android:windowSoftInputMode, adjustResize|stateHidden)

2) in Main

B4X:

Private Sub IME_HeightChanged (NewHeight As Int, OldHeight As Int)
    SearchView1.ActivityHeightChanged(NewHeight)
End Sub

For what are they? Do I need them?

Erel · Jun 28, 2017

They are used to resize the list when the keyboards shows.

SamuelP · Jun 28, 2017

I see. So that the last entries are not behind the keyboard.

If you check post#87 through post #90, your question is answered there.

As it is a class you can find them all looking at the source.

I'd like to ask does autocompleteedittext or this one do auto complete as I type? I mean does it fill the text portion with the first match of the list and then refine the list as I type more text

Erel · Oct 8, 2017

Yes. You can download the example and run it. It will take you 2 minutes to test...

Erel, would it be possible to attach the same list to multiple Editboxes?

I have dynamical added editboxes that would work with the same list, CoinBox1, Coinbox2, etc.

Is this possible?

Good timing. I'm just working on adding a search dialog to XUI Views. It will soon be released.

Erind Jushaj · Jan 15, 2019

The problem I had Erel is that because I am adding dynamically I cannot call the xxx_TextChanged as my editboxes have all the time a different name...

At the risk of getting in trouble for raising an old thread (again)

This is a very basic problem but i'm confused several times the question has been asked & answered! but always the same answer and no example (i am very visual and need to see it!!!)

B4X:

Sub Class_Globals
Private et As EditText
'change it to public!!

so

B4X:

Sub Class_Globals
Public et As EditText
'change it to public!!

should make et. available in my main module??

I need it as i want to clear the edit text when i have done with it. I could do it in the class. but it would be easier in Main..

Thanks

Yes. If you don't see it then press on Enter on that line. This issue is fixed for the next version of B4A.

Is it possible to add SearchView to activity via code?

Also in the thread about B4XSerializator, it is mentioned that SearchView has a limit of 500 list items. Is that still the case? I can't use B4XSerializator as the server is not in my control.

Erel · Apr 7, 2019

You can create a layout with only the SearchView and load it whenever needed. It must be added as a custom view.

There is no size limit.
