Get text

I am using this customlistview with some alterations it does almost everything I want....but one problem I can't solve is How to get the the text from all the lbl's so I can save it as a csv. I initially load a csv file but need to save it after user input,I've read all the posts in this thread but none help.
Any suggestions? Thanks Dave.

Didn't the map-function work ?

B4X:

sets.clear
sets.Put("TextinderMap", lbl1.Text)
File.WriteMap(Dir.Internal, "labels.map", sets)

You can use clv.GetPanel to get the base panel of each item. You can call Panel.GetViewAt(<your label index>) to get the label.

See the Button_Click event for an example.

Where is the library?

I wish people would include the library in the examples. Where can I find the CustomListView? I am a registered member so you can message me.

CustomListView is not a library, it's a custom class.

Cool Sig

@frapel

Now that's what I call a signature!
Very nice!

This would be a great example class to turn into B4A's new "custom view".

Erel · May 30, 2013

V1.10 is now available. This version adds designer support to CustomListView.

GMan · May 30, 2013

When i place a CustomView on an activity the TYPE-Field is disabled, so i cant change it to CustomListView ?

Erel · May 31, 2013

Have you added the class to your project?

GMan · May 31, 2013

Yes, and it shows in the top the correct version 1.1

I tried restarting B4A 2.71, but nothing changed...

klaus · May 31, 2013

What exactly did you do ?
I just tried it and it works perfect.

Best regards.

GMan · May 31, 2013

I have a blank activity and placed a CustomView on it - as written, the TYPE-part is still disabled.

Does this custom view work for you: [Class] AnotherDatePicker - A simple "web style" date picker ?

GMan · Jun 2, 2013

Hoi Erel,

yes, it works - also the CustomListView.

Reason why not working: i tried to choose the "wrong" TYPE-part in the part above.
As is saw laaaaater the CUSTOMTYPE-part should be selected and changed :sign0089:

I i would like to ask how can i make background transparent of the non-populated customlistview list because i would like to show activity color or image background instead of gray , Thanks in advance

Erel · Jun 3, 2013

You can change the background color in the Initialize sub:

B4X:

sv.Color = 0xFFD9D7DE 'this sets the dividers color

Change it to Colors.Transparent. As written in the comment the dividers color will also change.

Obv it works :sign0188:
Thanks Erel!!

Hi Erel,

I have added the custom list view from the designer.

Initially i am checking whether the checkbox is checked and if it true i am setting the checkbox.checked = true. After this it is calling the

Sub chk_CheckedChange(Checked As Boolean) and getting the below error - Null Pointer Exception.

Kindly let me know your Inputs.

B4X:

loadlanguagelistview_chk_checkedchange (B4A line: 105)

index = clv1.GetItemFromView(Sender)
java.lang.NullPointerException

Note : Before i was not bothered about the checkbox status and it was working fine.

Regards,
SK
