How can I implement a GetViewByName function ?

[fiaful]

Hi there!

I would need to build a function that will return me a view, contained in a panel, knowing only the name of the view (no ID, no tags) ...

The panel is populated by a call to other loadlayout and later in a sub I can call asynchronously use the method call GetView, passing the index of the view that I intend to use.

But since the designer I insert my view by specifying the name, I also want to take just using their name!

I tried building a function in java like this:

int Id = pBA.context.getResources().getIdentifier(Name, "id", pBA.context.getPackageName());
Log.d("B4A", "GetViewByName - Id = " + Id);
View V = container.getObject().findViewById(Id);
Log.d("B4A", "GetViewByName - V = " + V);
return V;

but the Id returned is always 0 (probably because the id is not mapped in the R class)

how could I do? how do you do it?

you could post a snippet that works?

Thanks to all in advance for any response.

ah! I forgot an important detail!

the layout loaded in the panel, that I mentioned above, is used as items in a listview ...

then each item in the list contains all the objects loaded by the loadlayout.

this excludes the possibility of creating a global map containing the view of the layout!

it gets more complicated!

Views do not really have names.
You can however create such a mapping yourself:

Sub LoadLayoutToPanel(p As Panel, file As String)
p.LoadLayout(...)
dim m As Map
m.Initialize
m.Put("Button1", Button1)
m.Put("Button2", Button2)
...
p.Tag = m
End Sub

The result is that in the Tag property of each panel you will have a map that maps between the "names" and the views.
