Android Question How to create an _ItemClick in a custome listview to click an Item

AndyChang · Nov 15, 2017

Dear Sir
I use Panel to build a listview which has string and bitmap shown together as my attached png.
The way of coding to build the listview is just like my second png.
Could anyone can give me a simple sample and show me how to create the _ItemClick
Thanks a lot for your response.

Post CODE as TEXT using Code Tags.

You are using Label2.Initialize("") Why you left the EVENTNAME Empty???????

AndyChang · Nov 15, 2017

Thanks Sir Manfred,
I have update the code to Label2.Initialize("Label2") and also fill all the other empty event_names.
But I still don't know how to establish a routine to get the item(position or index) when I click one of the many items.
Please help me.

lv.Initialize("lv")
lv_ItemClick is the click event I'm not at home to see how I do it

Thank you Ricky.

In my case, which View name should I use in the View_ItemClick. should I change the word View to Panel5 or scvorder or ...

Ricky D · Nov 15, 2017

It has 2 arguments I think #1 is the index and #2 is definitely Value as object

I use the customlistview

Ricky D · Nov 15, 2017

You can name it anything. I usually put in the name of the view

Dim tblShifts As Table
tblShifts.Initalise(me, "Shifts")

Sub Shifts_CellClicked(col As Int, row As Int)
End Sub

Sub Creat_Insert_f1design_and_show
    GetTableinfo2
    Listview1.RemoveView
    Listview1.Initialize("ListView1")
    Listview1.SingleLineLayout.Label.TextSize=20
    Listview1.SingleLineLayout.Label.TextColor=Colors.White
    Listview1.Clear
    For i=0 To TablenameCount -1
        Listview1.AddSingleLine(Tablename(i))
    Next
    Activity.AddView(Listview1, 0%x, 48%y, 47%x, 43%y)
End Sub

As The above example, I create a Listview named Listview1 (all text no image data)
Then I use the way as below to get the ItemClick position(index). It works very well.
Now I need to add image data into the list. So I use Panel to Add the line as I post before. It work well. But I don't know how to apply the code below to the new application, so that I can get the ItemClick position(index)
I need help very much. I guess that it should be very similar to the code below.

B4X:

Sub ListView1_ItemClick (Position As Int, Value As Object)
    ListView1_ItemClick_Select = True
    Dim recordID As Int
    Tablenm1 = Tablename(Position)
    Log("TableNow= "&Tablenm1)
    lblcommand.Text = "目前的設計檔案是 " & Tablenm1
    Log("fileProcessNow = "&fileProcessNow)
    TableNameNOW = Tablenm1
    If fileProcessNow = "Self" Then
        Cursor1 = SQL1.ExecQuery("SELECT itemno FROM " & Tablenm1 )
        Log("***  after cursor1 ****")
        For recordID = 0 To 9
            Cursor1.Position = recordID
            Itemno(recordID) = Cursor1.GetString("itemno")
            Log("Itemno= "&Itemno(recordID))
        Next

Where are you getting the Value and doing something with it?

Dear Ricky
I create a set of sqlite databases which content a lot of nail art data. I want to create an APP to help nail art user to design their own nail art.
This is the last function that I need to write. Please help me. Thank you very much.

You'll need to zip up your code so we can look for you. We can't do it with just snippets

You should use CustomListView. Everything will be simpler.

Dear Erel
I do need to learn CustomListView. But when I search the Key word [CustomListView] I find yourpost in 2012 7/15 (as below)
https://www.b4x.com/android/forum/t...xible-list-based-on-scrollview.19567/#content

B4A Library CustomListView - A flexible list based on ScrollView
Discussion in 'Additional libraries, classes and official updates' started by Erel, Jul 15, 2012.

It is too complicated for me to use.
I found a CustomView item in Designer Add View list, but I think it is not the CustomListView
Is there any simple example which can teach me step by step about the most basic CustomListView include _ItemClick
Andy

AndyChang · Nov 15, 2017

Dear Ricky
My APP is a little bit large because of the database size. I have to cut down a lot before I transfer the code to you.
So I prefer to learn CustomerListView first (as Erel suggest). If I can have a simple example which can teach me step by step about the most basic CustomListView include _ItemClick then it will be very helpful to me to solve the problem.
Thank you Ricky
Andy

    label4.Text = OrderQty(I)
    Panel5.AddView(label4,260dip,5dip,20dip,30dip)

'    Build the UnitPrice  part

    Dim label5 As Label
    label5.Initialize("label5") : label5.Color=Colors.Black : label5.Tag="label5" : label5.TextSize = 16
    label5.Text = OrderUnitPrice(I)

    Panel5.AddView(label6,330dip,5dip,70dip,30dip)
   
    PanelTop=PanelTop+PanelHeight+1dip

End Sub

Each time when I call this Sub I create a new item list in my ListView. There may have several item list in the screan. Each item list is an item of order.
This is the way I create my ListView
Then I need to create an _ItemClick for user to choose one item in the ListView
How to write this Sub code (what is the listname XXX when I write the Sub XXX_ItemClick)
What is the following code necessary to write in the Sub, so that I can get the position(index) that the user click

Dear Klaus
I found a post which you gave an example about how to add image to CustomListView. The Url is as below
https://www.b4x.com/android/forum/t...lexible-list-based-on-scrollview.19567/page-6
I learn from your example about CustomListView. My application needs to combine image and text data in the same line.
How can I achieve the task. Can you give me an example like you post in 2013
Thank you so much.
Andy
