Android Question Custom View / Designer

[Guenter Becker]

Hello,
my question is focused on building a desginerable custom control.

I knew that I can set/retrive the Designer "Text Properties" by code using the *Lbl View" of the "Public Sub DesignerCreateView (Base As Object, Lbl As Label, Props As Map)". But I'm missing to do the same with the Background Properties like Drawable/Border a.s.o. because I can not find the belonging Props in the Base Object or the mbase B4XView. I tried mbase.GetView but there is also no access to the Props. By the way I know that I can creat own DesignerProperties by code but I think the requested Props are still there and it will be silly to code them twice.

Question: Does Anyone can tell me how to get and set the Background Properties Values of the mbase View by code? A B4A code snipped would be fine.

Thank You in Advance
Guenter

mBase.Color = xui.Color_Red

or in the designer

Hey
Ok, I know that but what is with the other properties for the border, the gradient and the image? There are no properties listed in mbase for these.

because, mBase is a B4XView. Convert it to a panel and access it via the panel properties.

Ok, that is what I tried but it did not solve the problem!
If I do it (objPanel = mbase) the Panel View deals only with the properties Color and Background
Background = current Drawable state like ColorDrawable or GradientDrawable or BitmapDrawable
Color = Background Color if Background state is ColorDrawable

What I need to handle by code are all the values of the Background properties of the different Background states, in Detail:

Background = ColorDrawable, Properties: Color/Bordercolor/Borderwidth/radius?
Background = GradientDrawable, Properties: Orientation/First color/Second color?
Background = BitmapDrawable, Properties: ImageFile/Gravity?

Any Idea how to get access? If not I hope erel knew it?

Hello,
sorry but no one could give me a solution.
I found the first step of the solution. It is based on the background property of mbase.as(Panel) and than to use this with the javaobject like this
[CODE lang="b4x" title="This is in the DesignerCreatView Sub"]If GetType(mBase.As(Panel).Background) = "anywheresoftware.b4a.objects.drawable.ColorDrawable$GradientDrawableWithCorners" Then
Dim cd As ColorDrawable = mBase.As(Panel).Background
Dim jo As JavaObject = cd
Log($"Radius = ${jo.GetField("cornerRadius")}, BorderWidth = ${jo.GetField("borderWidth")}"$)
End If[/CODE]

I used the designer Base background properties to set the values for the colordrawable.
On the run I always get the error that the CD/mBase.As(Panel).Background is not initialized.

Anyone could give me an answer how to get the colordraw from the mbase background?

I suggest you to take a different approach and add custom properties for the colors you need. It will be simpler.

 

[Guenter Becker]

Hy Erel,
that is what I have done yet but it's not the elegant way because the values always there.
Ok, if it's not possible then I will take it.
Thank you
