Android Question catch SelectedIndexChanged event from custom control

Hello @lare
You should watch some of the video tutorials under learn (top of this page), once of the videos is about the IDE and letting the IDE auto create your sub events for you.

I get the IDE auto create subs for me.


Using the designer (Or you can get the IDE to auto create the correct sub vent for you)

Hi @Peter Simpson
I do not have problem with getting SelectedIndexChanged event of LocalB4XComboBox. I know that IDE can generate for me sub events. In the demo project that I attached, if you run it it works perfectly fine.


But I have problem, that I do not know how to do that same, with the B4XComboBox which is placed in custom control?!? It looks like that event (CustomCB1_SelectedIndexChanged) is never fired up, when I changed values in that combobox?

Is it even possible to send values, from ComboBox that is placed in custom control,
to the main activity form, when different value is selected in that ComboBox?

You should never add custom views like this.

Use the designer.

[B4X] I need 100 <custom view here>s. How to add programmatically?

Note that you will need to add Sleep(0) before you load the layout with the B4XComboBox, in DesignerCreateView.

Sorry Erel if I don't understand You, but did You mean that I can not make my custom view that consist of another custom view(in this case B4XComboBox)?

I added my custom view through the designer. I followed your example of 'LimitBarDemo2' and did the same.
I added New Module/Class Module/Custom View named it CustomCB and then I in designer add it on Layout(Add View/CustomView/CustomCB).
Then I define in Custom View class 'CustomCB' what I needed. But that is bad practice I suppose.




But then how I can use this of mine custom view on multiple activity if I need it???
If I add B4XComboBox directly on the activity like I did with LocalB4XComboBox then I can not easily reuse it?

No need to add these screenshots. They just make the thread unreadable.

No.

I say that you must add custom views with layout files.

Ok, sorry Erel, no more screenshots.
I will tray with layout files.
Thanks!
