Android Question CustomLayoutDialog without padding

[rraswisak]

base on thread https://www.b4x.com/android/forum/threads/customlayoutdialog-with-customlistview.82259/ , while SetSize is 100%x and 100%y, is it possible to make the dialog show without padding around it ?

many thanks

ok, i just figure it out, no need to adjust the padding, just make the dialog color to transparent

from sample above link, i modify Activity_Click event to this:

Sub Activity_Click
   Dim cd As CustomLayoutDialog
   Dim cdlg As Object = cd.ShowAsync("Choose item", "", "", "", Null, False)
   cd.SetSize(100%x, 100%y)

   Dim jo As JavaObject = cdlg
   Dim warna As ColorDrawable
   warna.Initialize(Colors.Transparent,0)
   jo.RunMethodJO("getWindow",Null).RunMethod("setBackgroundDrawable", Array(warna))

   Wait For Dialog_Ready (DialogPanel As Panel)
   DialogPanel.LoadLayout("CustomDialogLayout")
   For i = 1 To 20
       CLVDialog.AddTextItem("Item #" & i, i)
   Next
   Wait For CLVDialog_ItemClick (Index As Int, Value As Object)
   Log("Selected item: " & Value)
   cd.CloseDialog(DialogResponse.POSITIVE)
End Sub

I confirm that transparent dialog will not work on android 4, so i really need any help here...

Please upload a small project with the relevant layout.

here with small project how i show the dialog, in android 4 (emulator and real device) the dialog color still white while in android 7 the color was transparent as expected.

Thank you for your enlightment

This is not the correct way to build the dialog. You should instead set the size of the dialog to match the actual content.

Tips:
1. Remove the call to AutoScaleAll as the exact size is important here.
2. Code to set the dialog:

cd.ShowAsync("", "", "", "", Null, False)
cd.SetSize(280dip + 32dip, 220dip - 14dip)
Wait For Dialog_Ready (DialogPanel As Panel)
Log(DialogPanel)
DialogPanel.LoadLayout("1")

3. The panel with the content should be at the top of the layout.

Erel, what if the Panel has corner radius set ?, the background still visible on each corner

 

[Erel]

That's true. You can use round corners on newer devices only.
