Android Question Get value from view in customlistview

[RUNO]

I have customlistview with many columns containing from image and label containing panel.
How I get text from label if user clicked on image .

 

[Andrew (Digitwell)]

the image you uploaded is too small for me to see clearly, however,

you can assign the label to the tag of the image on creation (after load layout)

img.tag = lbl

then in the click event

private img as b4xview = sender
if (img.tag is label) then
log("text of label is "&img.tag.as(label).text)
end if

Thanks @Andrew (Digitwell)

Your screenshot means absolutely nothing as it's way too small.

Look at the code in the link below...

✅ Part 1 Basics - Creating long lists using xCustomListView with Lazy Loading - Newer developers

Hello All After thinking about it yesterday and having a quick chat with Erel, I decided that my previous long list examples were not basic enough for newer B4X developers, so I put together a minimal xCLV with LL code example together with comments in the code module. There are no themes...

@Andrew (Digitwell) 's solution works well if applied correctly. But, your explanation of your problem is not good. If you cannot express it well in English, your best bet is to upload your project or at least a clear copy of you designer item layout tree and the items layout where you will not need binoculars to see it. With your cooperation, your issue can be solved.
Also, take a look at @Peter Simpson 's project. It helped me a lot, way back when I needed a push.

Thank you all for your attention to my problem
Maybe I couldn't explain the problem, so I upload a piece of code for you, maybe one of you can help me and all of you are able to that.
my code too primitive.

Here is a working version.

The comments with DIG: show the changes I have made.

• You should respond to the click on the Imageview not the clv.
• You weren't taking the data from the CLV row in Visiblerangechanged, I'm not sure why this worked before.

I would most probably make more use of functions if I were to write this for example.

[B4X] "Code Smells" - common mistakes and other tips

"Code smells" are common patterns that can indicate that there is a problem in the code. A problem doesn't mean that the code doesn't work, it might be that it will be difficult to maintain it or that there are more elegant ways to implement the same thing. Remember that not everything is clear...

www.b4x.com

For example,

            m = MyList.Get(i+2)
            Dim link1 As String=URL &"ad1/image/pic/"& m.Get("folder")&"/"&m.Get("image")
            Dim id As Int=m.Get("id")
            Dim j As HttpJob
            j.Initialize("", Me)
            j.Download(link1)
            Wait For (j) JobDone(j As HttpJob)
            If j.Success Then
                id3  = CreateItem(link1,id,j.GetBitmap)
            End If

could become a function which takes a parameter and returns an image data

private sub getimageandcreateitem(idx as int) as resumeablesub
private m as map
m = MyList.Get(id)
            Dim link1 As String=URL &"ad1/image/pic/"& m.Get("folder")&"/"&m.Get("image")
            Dim id As Int=m.Get("id")
            Dim j As HttpJob
            j.Initialize("", Me)
            j.Download(link1)
            Wait For (j) JobDone(j As HttpJob)
            If j.Success Then
                return  CreateItem(link1,id,j.GetBitmap)
            else
                return null
            End If
end sub

then getDT can be

    For i = 0 To MyList.Size-1  Step 3
        Log(i)

        wait for (getimageandcreateitem(i)) complete (r As ImageData)
        id1 = r
 
        If (i+1) <MyList.Size Then
            wait for (getimageandcreateitem(i+1)) complete (r As ImageData)
            id2 = r
         
        Else
            ' id2.title = DIG: Bug here
            id2  = CreateItem("","",Null)
        End If
        If (i+2) <MyList.Size Then
            wait for (getimageandcreateitem(i+2)) complete (r As ImageData)
            id3 = r
        Else
            'id3.Title = DIG: Bug Here
            id3  = CreateItem("","",Null)

        End If

which is much easier to maintain

EDIT: Fixed bugs in example code above - copy/paste error (download file is correct)
