Hello!

Not sure if it is alright to post on this thread, but love this library!

However- In B4A, any panels in the first LoadLayout are shown over the DraggableBottomCard. Even though the Draggable bottom card was initialized and created after LoadLayout?

I tried:
B4X: 
asdbc_main.BodyPanel.BringToFront
asdbc_main.Headerpanel.BringToFront
asdbc_main.DarkPanel.BringToFront
asdbc_main.BodyPanel.Parent.BringToFront

Thank you!


Edit- Figured it out, it was because of panel elevation on my form controls. Here was my fix:
B4X: 
Dim pp As Panel = asdbc_main.BodyPanel.Parent
pp.Elevation = 1dip

I use the DraggableBottomCard in the immersive mode of an Acticvity that fills the entire screen. On devices with a notch, the problem arises that when the card is fully opened (ExpandFull), the notch overlaps the header panel. Therefore I would like to be able to adjust the height of the header panel to react to a notch. I can determine the height of the notch myself. But I can't then adjust the height of the header panel. Would it please be possible to implement a setHeaderHeight(Height As Float) in addition to the getHeaderHeight()? Thanks a lot!

Thank you, but it is not the FirstHeight or SecondHeight I'm asking for but the HeaderHeight.

The notch height of a device only affects the HeaderHeigt when the card is fully opened in Immersive Mode. Therefore, I want to adjust the HeaderHeight when the card is fully opened and the device has a notch. In all other cases the HeaderHeight will not be adjusted.


Currently, I can only have the same HeaderHeight for both sizes. There is no way to change it.

Changing the height of the header is not provided. I have already spent 20 minutes implementing it, but I would have to make deep changes. So it will not be implemented for now.

I looked at your images, I recommend you to change the height of the body, everything else would look strange. Just take the height of the activity, subtract the height of the notch, then you have the perfect height.

Or just check during initialization if there is a notch and adjust the height of the header...
The notch does not spawn where the menu is expanded, but is there all the time...

Far from beeing perfect, but it seems to work in B4A:

B4X: 
Public Sub setHeaderHeight(pfltHeight As Float)
    Dim fltHeightDiff As Float
  
    fltHeightDiff = pfltHeight - g_header_height
  
    If fltHeightDiff = 0 Then
        Return
    End If
    g_header_height = pfltHeight
    If expand_state = 1 Then
        xpnl_card_header.SetLayoutAnimated(0,0,0,g_width,g_header_height)
        xpnl_card_body.SetLayoutAnimated(0,0,g_header_height,g_width,g_first_height + g_header_height)
    Else
        xpnl_card_header.SetLayoutAnimated(0,0,0,g_width,g_header_height)
        xpnl_card_body.SetLayoutAnimated(0,0,g_header_height,g_width,g_second_height)
    End If
    xpnl_card_header.Height = g_header_height * 2
    VisibleBodyHeightChanged
End Sub

This class works great on Android. Thank you Alexander!

Currently I’m struggling with it B4i. I added a reference to GestureRecognizer found here. Now it compiles without any error. But the menu does not show up at all. Probably I’m doing some wrong when initializing the card like this:

B4X: 
Private Sub Application_Start (Nav As NavigationController)
    NavControl = Nav
    MainPage.Initialize("MainPage")
    MainPage.RootPanel.LoadLayout("frm_main")
    NavControl.ShowPage(MainPage)
  
    asdbc_main.Initialize(Me,"asdbc_main")
    asdbc_main.Create(MainPage.RootPanel,MainPage.RootPanel.Height/2,MainPage.RootPanel.Height - 60dip,50dip,MainPage.RootPanel.Width - 20dip,asdbc_main.Orientation_MIDDLE)
    asdbc_main.HeaderPanel.LoadLayout("frm_header")
    asdbc_main.BodyPanel.LoadLayout("frm_body")
  
End Sub

I provided a simple B4i Example that can be used to test this issue. Any help is appreciated!

Thanks, Thomas
