Android Question GetDeviceLayoutValues.ApproximateScreenSize VS ActivitySize

[MarcoRome]

Hi all, i have this problem. Why beetwen GetDeviceLayoutValues.ApproximateScreenSize and ActivitySize i have different Result ??

This is code in Activity_create

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("1")
' < 4.5
If GetDeviceLayoutValues.ApproximateScreenSize < 4.5 Then
    Label2.Text = "ApproximateScreenSize: " & GetDeviceLayoutValues.ApproximateScreenSize
' > 4.5 e < 8
Else If GetDeviceLayoutValues.ApproximateScreenSize > 4.5 AND GetDeviceLayoutValues.ApproximateScreenSize < 8 Then
    Label2.Text = "ApproximateScreenSize: " & GetDeviceLayoutValues.ApproximateScreenSize
'Tablet > 8
Else If GetDeviceLayoutValues.ApproximateScreenSize > 8 Then
    Label2.Text = "ApproximateScreenSize: " &  GetDeviceLayoutValues.ApproximateScreenSize
End If
 
End Sub

This is code in Design Script:

'All variants script
AutoScaleAll
 
Label1.Text = "ActivitySize: " & ActivitySize

The result is:
GetDeviceLayoutValues.ApproximateScreenSize = 3.60
ActivitySize = 3.23

Any idea ??

Thank's
Marco

ApproximateScreenSize is the size of the whole screen. ActivitySize is the size of the activity (without the top and bottom bars).

Erel, please clarify. What does the number mean?
a) Is it the horizontal Size? Vertical Size? Diagonal? Area?
b) Inches or Centimeters?

a) Diagonal
b) Incches

a) Diagonal
b) Incches

Thank you so much!

Is there a way to know the physical horizontal and vertical sizes, or at least, the screen's aspect ratio?

 

[Erel]

Dim lv As LayoutValues = GetDeviceLayoutValues
Log(lv.Height / lv.Scale / 160)
Log(lv.Width / lv.Scale / 160)

For more accurate results, you need to use the exact scales: https://www.b4x.com/android/forum/threads/same-physical-display-size.14037/#post-79434
