When I do 5 times LOADLAYOUT, app is slowly

[petr4ppc]

Dear friends,

I know, that it can be one of basic question, but help me please.

When I open 5 different layouts in one scrollview via loadlayout, then scroll function is slow. I am trying to do:

1)
removeview

2)
If panel1.IsInitialized=True Then panel1.Enabled=false
If panel2.IsInitialized=True Then panel2.Enabled=false

but this can not solve my trouble. I have read forum, but I cant find something what help me..

When I push BACK BUTTON and then I start APP again, everything is OK, but when I open all of my layouts, scroll is slow again...

I am opening 10 small jpg images in each layout

Please very much, what can I do?
Thank you

Can you upload your project (File - Export as zip)?

It looks, that trouble was because I do everytime, when I load each layout and each image:

   If File.Exists(File.DirInternal,"image3.gif")=True Then 
     image3 = LoadBitmapSample(File.DirInternal, "image3.gif", 100%x*scale, 100%y*scale) 
     ImageView3.SetBackgroundImage(image3)    
   End If

and now I have in code only

When I start app first time then I read images:

 image3 = LoadBitmapSample(File.DirInternal, "image3.gif", 100%x*scale, 100%y*scale)

and when I load layout then I use:

   If File.Exists(File.DirInternal,"image3.gif")=True Then 
         ImageView3.SetBackgroundImage(image3)    
   End If

and it looks good...I hope....because I will add layouts with images

Hi petr4ppc,

If you have ever read Klaus 's Beginer Guide,You could see his technique.
load the Image only one time.

If FirstTime Then
Img3=LoadBitmap(File.DirInternal, "image3.gif")
End If
