Android Question Get All Items Values into Arrays

[Adamdam]

Dear All,

From this tutorial: [B4X] [XUI] CustomListView - lazy loading / virtualization

I create CustomListView which has EditText, CheckBox, ..
I need to copy all items data into array of strings, like the following code:
this code is not right, I need to correct it:

Dim StrArray(100) as string
Dim ValArray(100) as int
.
.
For i = 0 to maxItems
StrArray( i ) = CustomListView...EditText1 ( i ) ' this code not right , I need to correct it.
ValArray( i ) = CustomListView...CheckBox1 ( i ) ' this code not right , I need to correct it.
Next



wait for correct previous codes to copy all items data into Arrays as above.
Thanks in advance.

Best regards

dont know if this works.. but this might give you a hint

Dim StrArray(100) as string
Dim ChkValue(100) as Boolean

For i = 0 to CustomListView.GetSize - 1

dim pnl as panel = CustomListView.GetPanel(i)

dim lbl as label = pnl.GetView(0)
dim chk As CheckBox = pnl.GetView(1)

StrArray( i ) = lbl.text
ChkValue(i) = chk.Checked


Next

thanks Mr. ronell for your answer,
I test your code, but it give me error, " not initialized " . how can repair this error ??

another question, i have many/different objects in each CustomListView, how can i know the orders of these objects in panel ?

best regards

make sure the customlistview is initialized/loaded in the activity before using the loop.

i have many/different objects in each CustomListView, how can i know the orders of these objects in panel

i rewrite the code so that you dont need to know the order of the views

Dim StrArray() as string
Dim ChkValue() as Boolean

For i = 0 to CustomListView.GetSize - 1

dim pnl as panel = CustomListView.GetPanel(i)

 
    For Each v As View In pnl.GetAllViewsRecursive
        If v Is Label Then
         
            dim lbl as label = v

            StrArray(i) = lbl.text

        Else if v is CheckBox then

            dim chk as CheckBox = v

            ChkValue(i) = chk.Checked

        End If
    Next

Next

Refer to the order in Designer ViewTree for Item/Row layout ... this dictates the index of the CLV panels views.

note you can also directly reference a views properties without declaring another view. ie:

For i = 0 to CustomListView.GetSize - 1
    dim pnl as panel = CustomListView.GetPanel(i)
    StrArray( i ) = pnl.GetView(0).Text     ' 1st view listed in Designer ViewTree for CLV Item/Row layout
    '............

Dear Mr. Ronell, and Dear Mr. Mangojack
Many thanks for your interesting and for your answering.

Mr. Ronell, your code work well,
sure I initialize the customListView first and it even filled by user,
I try to make little change as: (not work)
Dim vv As View = pnl.GetView(2)
Dim lbl1 As Label = vv
Log(lbl1.Text)
while your code work well, Are you have solution to run my little change ?


Mr. Mangojack, for the ordering, you are right,
but the code you attached not work, where parameter "Text" not defined with "pnl.GetView(0).Text"

best regards

but the code you attached not work, where parameter "Text" not defined with "pnl.GetView(0).Text"

you need to adapt the index to the correct view index you used in your layout as mentioned by @mangojack

StrArray( i ) = pnl.GetView(0).Text ' 1st view listed in Designer ViewTree for CLV Item/Row layout

If you expect a more congrete help/answer then it is better to upload a small project which shoes the issue.

Dear Mr. DonManfred, Dear Mr. Ronell

Many thanks for your interest and answering.
attached example.
still have one problem : all objects work well except CheckBox ( not work )
(in attached example : press done button to see all information of cards in log)

Hope to find solving for the problem of CheckBox.

Best regards

 

[Adamdam]

Dear Mr. DonManfred, Dear Mr. Ronell

Are you test the previous attached example ?

Hope to find solving for the problem of CheckBox, it nod defined so, it not read.

Best regards

 

[mangojack]

The reason you were having problems / errors .. The Card List has all views placed on a secondary panel which had to be accessed first.

There is no need to loop thru all views testing for there type prior to accessing them. Deal with them directly.

I am still unsure what you are trying to do in regards to 2nd array and checkbox value / state ? (post #1)

Try the attached project ... Click and Study code in the DoneBn_Click sub.



PS: Apologies on behalf of Mr. DonManfred & Mr. Ronell not replying ... I believe they were at the Races .

Dear Mr. Mangojack,
Many thanks
It work well,

Thanks

Dear Mr. Mangojack, Many thanks .It work well, Thanks

I have uploaded an edited sample .
I mistakenly declared the panels as Panels instead of B4XViews , which allows direct access to panel Views properties.
