End Sub
Sub button3_click

Activity.LoadLayout ("layout3")

You can try using Activity.RemoveAllViews before loading another layout.
(I do not know if this will work).

However, it is likely that you're trying to get something in a twisted way.
Probably you should use more Activities or, at least, more Panels (loading the layouts in them and displaying them when necessary).

Thanks LucaMs.., But Activity.RemoveAllViews didn't work properly.

Activity.RemoveAllViews will remove all views. It should work. Though as Luca wrote this is not the best design.

But, I have HorizontalScrollView with many Button, after the use of Activity.RemoveAllViews i got following problem

This is my code for main Layout:

Activity.LoadLayout("Main") 
itemSize = HsvMain.Width / 3
    HsvMain.Panel.Width = itemSize * 7
        Table = HsvMain.Panel
        Dim p As Panel
        p.Initialize("")
        p.Color = Rnd(0x90000000, -1)
        BtnHome.RemoveView
        BtnListing.RemoveView
        BtnConfig.RemoveView
        BtnAddBk.RemoveView
        BtnSearch.RemoveView
        BtnProfile.RemoveView
        BtnLogut.RemoveView
        BmpHome.Initialize(File.DirAssets,"Home.png")
        BtnHome.SetBackgroundImage(BmpHome) 
        HsvMain.Panel.AddView(BtnHome, itemSize*0, 0, itemSize, HsvMain.Panel.Height)
        HsvMain.Panel.AddView(BtnListing, itemSize*1, 0, itemSize, HsvMain.Panel.Height)
        HsvMain.Panel.AddView(BtnConfig, itemSize*2, 0, itemSize, HsvMain.Panel.Height)
        HsvMain.Panel.AddView(BtnAddBk, itemSize*3, 0, itemSize, HsvMain.Panel.Height)
        HsvMain.Panel.AddView(BtnSearch, itemSize*4, 0, itemSize, HsvMain.Panel.Height)
        HsvMain.Panel.AddView(BtnProfile, itemSize*5, 0, itemSize, HsvMain.Panel.Height)       
        HsvMain.Panel.AddView(BtnLogut, itemSize*6, 0, itemSize, HsvMain.Panel.Height)

'Load Next Layout
Sub btnSearch_click
Activity.LoadLayout ("Search")
'This Layout contain many views
End Sub

'Now i want to load Main layout again
Sub BtnMain_click
Activity.RemoveAllViews
Activity.LoadLayout("Main")
End Sub

Now i am getting Design problem like this..

You should use different Activities instead of removing and reloading layouts, thats the standard way Android works.
Or you could use Panels with the layouts and handle their Visible property.

Thanks klaus,..but is it possible to use same HorizontalScrollView in all activity..?

 

[klaus]

You should explain more in detail what exactly your user interface should do.

Thank u, I solved the problem with Panel...My code is..

panel1.Initialize("")
panel1.LoadLayout("Main")
Activity.AddView(panel1, 0, 0, 100%x, 100%y)
Initialize
