display a comma on a list view

[Netpower8]

Is there a way to display a comma on a list view? The comma is also a delimeter seperator for the list. Is there a command to set the comma as a comma not a delimeter. Thanks for the reply

[Charles Wilt]

Yes. First build your list as a string using a different delimeter.

Use SetList( list, delimeter ).

Thank you very much. This has been bothering me for some time

Hi Charles, this is my first post.
I am not able to display in a ListView items having a comma (I mean the full screen ListView, not a List). The solution you propose works for a List but not for a ListView.
Can you please post a working example that shows how to create a ListView with items separated by a custom delimiter, other than the comma?

This is my sample test script:

//Called when application is started.
function OnStart()
{
    var data = "Hi, Joe%how are you?";
    lay = app.CreateLayout( "linear", "VCenter,FillXY" ); 

    // this shows two lines (not what I want):
    // Hi
    // Joe%how are you?
    lvw1 = app.CreateListView(data);

    // ...so I create a standard list with custom delimiter
    // which displays the two lines that I want:
    // Hi, Joe
    // how are you?
    lst = app.CreateList();
    lst.SetList(data,"%");
    lay.AddChild(lst);
    app.AddLayout(lay);

    // now I try to assign this list to a new ListView
    // but the result is [object Object]
    lvw2 = app.CreateListView(lst);
}

BTW, reading the documentation on ListView methods at http://wiki.droidscript.me.uk/doku.php?id=built_in:lists after the examples, I noticed that many of them don't work; I tried ListView.AddItem, ListView.GetLength, ListView.InsertItem and few others: they exist for List but not for ListView, contrary to what the methods table claims. For example, The Debug log says "Script Error: Object has no method 'AddItem', Line 7, sample.js.".

Christian,
On the wiki comment, the page you linked to is the page about the List control, not the ListView, which is at http://wiki.droidscript.me.uk/doku.php?id=built_in:listview

It is a historical accident that list control referred to on the List page has been named ListView. That should probably be changed.

As regards your question about putting commas in a ListView, the simple fact seems to be that it cannot be done.

If you need something that looks/acts like a ListView, you will probably need to create a custom dialog.

I will post a sample function
myListView
in a couple of minutes.

[Steve Garman]

//Called when application is started.
function OnStart()
{

// myListView can take list,title,callback
lvw1= myListView("aaa,bbb,ccc","my title",lvw1_OnTouch);
lvw1.Show();

// this is more like what you are looking for

var data = "Hi, Joe%how are you?";

lvw2 = myListView();
lvw2.SetList(data,"%");
lvw2.Show();

}

function lvw1_OnTouch(item,body,icon,index)
{
app.ShowPopup(item);
lvw1.Dismiss();
}

function myListView(list,title,callback)
{
var lv = app.CreateDialog( title,"noXcancel" );
var lay = app.CreateLayout( "Linear", "" );
var lst = app.CreateList( list,1,1 );
lay.AddChild( lst );
lv.AddLayout( lay );
if(callback) lst.SetOnTouch( callback );
else lst.SetOnTouch(_Cb(lv,"dfltCb"))

lv.dfltCb=function()
{lv.Dismiss();}

lv.SetList = function(list, delim)
{
lst.SetList(list, "%");
}
return lv
}

Thanks Steve, your help was precious, I could use your sample in my project, and it works. So, the idea is to use a standard List instead of a ListView, but show it in a dialog that shows full screen and that can be dismissed. Great!

Thanks.

Thanks for the feedback Christian.

It is always good to know someone has understood the code and not just pasted it.

bit late to this but that really bugged me, found the html encoding of a comma so you use the html as your type for the create layout

BTW anyone, is there more options for lists other than these default lists? 

function OnStart()

{

    //Create a layout with objects vertically centered.

    lay = app.CreateLayout( "linear", "VCenter,FillXY" );    

 

    //Create a list and add it to layout.

    var data =

    "<font color='#ff0000'>Red&#44;comma here</font>,"+

    "<font color='#00ff00'>Green</font>,"+

    "<font color='#0000ff'>Blue</font>"

    lst = app.CreateList( data,-1,-1,"html" );

    lay.AddChild( lst );

    

    //Add layout to app.    

    app.AddLayout( lay );

}
