B4A v2.30 beta - loadlayout problem

[wl]

Hello,

It seems 2.30 beta has a problem loading a layout on a panel. It generates a Java exception that the layout could not be loaded.

Dim p As Panel
p.Initialize("panel")
p.LoadLayout("filterpanel")

I reverted back to v2.25 and there it works (again).

Same problem with me also. It was worked up to 2.22 .

Can you post the stack trace from the logs (and also upload the layout file)?

Erel,

As I uninstalled the B4A 2.3 beta and other info could be relevant: I will send the project including the few steps to take to reproduce the problem to support ?

I see it and it will be fixed.

The problem happens because you load the layout before adding the panel to its parent (so the panel doesn't have a known size yet).

 

[wl]

ok thanks !

Besides the errors related to loading a layout into a panel (which I know now is related to undeclared panel's size and fixable) I have a problem loading correct layout variants (and it's the same in 2.2). To be short, if I don't have a specific variant for the device I'm testing, the app will always pick the smallest variant I have in the layout file, like 320x480.
I don't know, may be it's by design; I searched the tutorials and posts but couldn't find any info on how b4a picks the layout variant if it cannot find a matching set.
Example: I have the following variants: 800x1280/1280x800, 600x1024/1024x600, 320x480/480x320 all in one layout file. When device's screen is exact match, it's fine, it picks the right layout variant. But if I load the app on 1440x900 screen, it picks 480x320 layout, though logically the best match would be 1280x800. Same thing about let's say 1280x720 (i use this size on my hardware accelerated VM simulator to capture apps' promo videos at 720p) - it picks 480x320 instead of much closer 1024x600 variant.

This is not related to this issue.

The variants you wrote have no meaning without the scale value.

Please start a new thread and upload the layout file.

Erel,


Just to let you know: while awaiting your fix I reinstalled 2.30 beta ans siwtched the order of the code (first adding the panel before loading the layout).

This worked, but in this way the rightmost control in my panel was not shown.

Just to let you know...

I did the same yesterday, worked for me too, no other problems so far.

 

[Erel]

This worked, but in this way the rightmost control in my panel was not shown.

Have you checked whether it is the layout script that causes this issue?

The script would not have worked correctly in the first case as the size of the panel was 0.

Same here - I just did the following and it worked again

I had the same problem, I switched this following from

If PnlLayouts.IsInitialized Then
Activity.RemoveViewAt(0)
End If

PnlLayouts.Initialize("")
PnlLayouts.LoadLayout(Layout)
Activity.AddView(PnlLayouts, 0, 0, 100%x, 100%y)

to

If PnlLayouts.IsInitialized Then
Activity.RemoveViewAt(0)
End If

PnlLayouts.Initialize("")
Activity.AddView(PnlLayouts, 0, 0, 100%x, 100%y)
PnlLayouts.LoadLayout(Layout)

and it started working

Erel My CustomTabHost now doesn't work because of this.

How do I get around this problem?

Do I have to rewrite all my internal code for the class?

regards, Ricky

***** Disregard - I am using the AddTab feature of the class to get around this issue

 

[Erel]

How do I get around this problem?

This issue is only in the beta version. V2.30 which will soon be released will not be affected.

Erel,

I got an email with a link to the 2.30 download a week (or 2) ago.

Is this the beta or the fixed version?

 

[Erel]

That is the beta version. The stable version will be released next week.

 

[sorex]

Cool, I'll just wait for the stable version then. Thanks

Panel.LoadLayout error in v2.30

Hello,

I still have this problem in v2.30...

Here is a code where I am getting this:

svcClient.Initialize(100%y)
svcClient.Panel.LoadLayout("frmClientDetails")

Any ideas what to do here?

Thanks,
Elad.

 

[Erel]

Are you sure that you are running v2.30 (check it in the About box)?

Can you post the stack trace from the logs?

 

[drmover]

Yes, I am sure - I checked it again...

Can you please guide me how can I post the stack trace from the logs?

Thanks,
Elad.
