Android Question Click in view - CLVNested

[Lucas Eduardo]

Hello, i am trying to make a layout that have three views in each item of CLV and it's a CLVNested.

I did an example project to demonstrate that it's not working. Is there a way to do this with CLVNested ?

this is not working

Sub Label1_Click
    Dim index As Int = clvItem.GetItemFromView(Sender)
    Log("label1: "&index)
End Sub

Sub Label2_Click
    Dim index As Int = clvItem.GetItemFromView(Sender)
    Log("label2: "&index)
End Sub

CLVItem_ItemClick event is raised whenever an internal item is clicked.

You can see how it is handled in tpc_OnInterceptTouchEvent. It should be simple to pass the X offset and find the correct view based onit.

Sorry, i don't how to do this. Can you give an example?

Thank you.

Change CallSub2 to CallSub3 and add the X parameter to the event.

Change CallSub2 to CallSub3 and add the X parameter to the event.

CallSub3(ScrollingCLV, "Panel" & "ClickHandler", ScrollingCLV.GetRawListItem(innerIndex).Panel, X)

Thank you for your reply, i followed your suggest and i get this error
java.lang.Exception: Sub panelclickhandler signature does not match expected signature.

What could be?

java.lang.Exception: Sub panelclickhandler signature does not match expected signature.

have you added the new parameter to panelclickhandler?

 

[Lucas Eduardo]

I don't think so, i don't undestand where add this new parameter to panelclickhandler. Can you show me?

i tryed this, but gave me the same error

Sub CLVItem_ItemClick (Index As Int, Value As Object, test As Int)
    Log("test: "&test)
    Log("Value: "&Value)
    Log("Index: "&Index)
End Sub

Thank you.

You are correct. My previous suggestion will not work.
You can instead store the offset in a global variable and get it inside the event sub.

Sub CLVItem_ItemClick (Index As Int, Value As Object)
 Dim offset As Int = Nested.ClickedOffset

I did it but i don't know how to get the correct view.
i tryed this but gave me an error.

Dim lbl As Label = clvItem.GetPanel(Index).GetView(offset)

and

Dim lbl As Label = clvItem.GetPanel(clvItem.FindIndexFromOffset(offset)).GetView(0)

Probably not the correct way to get the view, can you show me the correct way?

Thank you.

Assuming that your items layouts are not too complicated it should be quite simple. Something like:

Dim pnl As B4XView = clvItem.GetPanel(Index)
For i = 0 To pnl.NumberOfViews - 1
Dim v As B4XView = pnl.GetView(i)
if v.Left <= offset And v.Left + v.Width >= offset Then
  Log("This view")
End If

 

[Lucas Eduardo]

clvItem.NumberOfViews

Is it the correct way to get total of NumberOfViews?

Public Sub getNumberOfViews As Int
    Return CLV.GetPanel(0).NumberOfViews
End Sub

or should be this?

For i = 0 To clvItem.GetPanel(0).NumberOfViews - 1

 

[Erel]

I've fixed my code. It should be pnl.NumberOfViews.

 

[Lucas Eduardo]

I'm never getting the Log("This view")
In my layout i just have two labels.

 

[Erel]

Debug it. Put a breakpoint and check the offset and the views.

 

[Lucas Eduardo]

pnl.NumberOfViews returns 0. Is it correct?

 

[Erel]

It is correct. If it is not what you expect then you did something wrong.
