Limitations of views and spinners in one panel

Hello.

I have troubling with a lot of views and spinners in one panel.
Somehow I didn't manage to connect a main spinner with different
other spinners using visibility functions.

Strangely enough, no problem with other views like textview.

I wonder if there are limitations regarding the combination of a lot
of spinners and other views within one panel and b4a.

Hope someone out there knows the answer.

grtz.

Hi Klaus,

Thanks for your reply.

My project isn't finished yet so I will give you a part of my code instead,
with explanation what I want to achieve in the end.

Sub Spinner2_ItemClick (Position As Int, Value As Object)

If Value = "Show Spinner9" Then Kleding = True
Spinner9.Visible = True

If Value = "Show edtTitel" Then Kleding = True
edtTitel.Visible = True

If Value = "Hide edtModel" Then Kleding = True

If Value = "Hide edtBouwjaar" Then Kleding = True
edtBouwjaar.Visible = False


// groupcode above is one of the 12 other similar groupcodes that
you have to read as follows:

Spinner2 is the most important spinner of all the spinners on this panel.

Here you select item 'Kleding', the spinner9 will be visible, together with
edtTitel text, but hide the 2 textviews (edtModel and edtBouwjaar)

The rest of the views on this panel will stay visible or just invisible.

I have 12 spinners and 3 textviews in one panel.

But everytime I select an item in Spinner2, I always get the wrong spinner getting visible.

If I use one groupcode instead of 12 on this panel, then everything goes well.

So it looks to me that either b4a/android can not handle a lot of spinners and views in one panel
or maybe it's just me who doesn't know how to code in the right way. //

I hope you can figure it out.

grtz.

I think that you need to post more of your code as the above statement is not consistant witht the code.

Also you have not applied THIS post to the code.

It would be better to see the project, it does not matter if it is finished or not as long as we can see what is meant to be happening. I do however understand that it may be an app that you want to keep to yourself until it is finished.

Hi Kickaha,

Sorry, this will be an app for the store, free or not.
That's why I can't expose it right now.

Yes, I already applied your suggestion and worked only if I
use one group of code instead of 12.

And if I select another item of the main spinner2, I still see
the spinner that was belong to the other item of Spinner2.

So, basically for now I'm really stuck, after many attempts.

It worked though thanks to all the advises on this forum,
but unfortunately not for 100%.

Erel said in a different thread that Android can not handle too much views
or complcated animations in a single panel.
I hope that's not the issue in my case.

I agree with kickaha, without more code and explanations it is impossible to give you a concrete advise.

- You say:

This code below from your post shows the contrary.
B4X: 
If Value = "Show Spinner9" Then Kleding = True 
Spinner9.Visible = True

- I'm afraid that you don't understand how Spinners do work.
You say:
Here you select item 'Kleding', the spinner9 will be visible, together with
edtTitel text, but hide the 2 textviews (edtModel and edtBouwjaar
Click to expand...
But if you select 'Kleding' that means that Value = Kleding !
So Value can not be "Show Spinner9", "Show edtTitel" etc.

- Views limitation:
Erel said in a different thread that Android can not handle too much views or complcated animations in a single panel.

Erel said: 'If the panel is full of views then it might be more difficult for Android to animate it.'
The number of views you have on your panel is not a problem.


- I would suggest you a code like this one:

At the beginning all views are hidden and acording to the selected value you show the needed views and set the variables to the needed values.
You should give the Spinners more meaningful names like you did for the EditText views.

But without more code and explanations we must guess what you really want to do, but cannot give you concrete advices.

Best regards.

Hi KLaus,

Thanks for your time and effort.

I showed an example that worked the best, just one of the many attempts.
So I didn't show the one from Kickaha.

According to your code: I also had a config with 'spinner.visible = False'.
But not in combination with your 'select....case...end select' approach.

Ï'm gonna try your config. and you will hear some result from me soon.

Update:

Thanks to Erel , Kickaha and Klaus and after many attempts, I finally got the solution for this issue.

I made a tutorial sample for this and might be useful to anyone dealing with the same problem.

Before uploading it for the public, I would like that Erel, Kickaha or Klaus wants to
test it first to be sure of.

Just let me know, guys.

grtz.
