Android Question fontsize multiple layout

tempo fa dovevo ricorrere al problema sul font ma che non ho mai preso in considerazione, oggi devo lanciare un prodotto e devo risolvere, non ho capito molto delle varie risoluzioni con i fontsize, chiedo aiuto per risolvere il problema

time ago I had to resort to the problem on the font but I never considered, now I have to launch a product and I have to solve, I did not understand a lot of the different resolutions with fontsize, ask for help to solve the problem

Code:

Public Sub fonsize(size As Float)

Dim LayoutVal As LayoutValues = GetDeviceLayoutValues 'Preleva dimensione del dispositivo
Dim Dens As Float = Density 'Preleva la densità del dispositivo
Dim Scale As Int = LayoutVal.Scale

If Scale = 1 Then ' for low-density
size = (size * 2) / Dens
Else If Scale = 2 Then ' for medium-density
size = size / Dens
Else If Scale = 3 Then ' for high-density
size = (size * 1.5) / Dens
Else If Scale = 4 Then ' for extra-high-density
size = (size * 2) / Dens
Else If Scale = 5 Then ' for extra-extra-high-density
size = (size * 2.5) / Dens
Else If Scale = 6 Then ' for extra-extra-extra-high-density (launcher icon only; see note above)
size = (size * 3) / Dens
End If

Return size

End Sub

Thank

 

I do not use design but written the Institute code, AutoScaleAll, in this case as the use!!

 

Take a look at this discussion

http://www.b4x.com/android/forum/threads/max-text-size.54101/

 

But how should it be done as it's not always possible to use the designer to create views. For instance I'm designing a class that could be used full screen but can just as likely be used on a panel occupying a quarter of the available screen space. Using the MeasureString approach as used here http://www.b4x.com/android/forum/threads/max-text-size.54101/ works but for some reason the MeasureStringHeight needs a slight adjustment and applying a fixed scaling value of 1.75 seems to be the only option other than to use the alternative method which is to use the StringUtils and Reflection libraries which then adds a larger overhead to the class which I am attempting to keep as minimal as possible.

 

Thanks for the explanation and the link (I've not read this before as I mistakenly thought it related only to the designer).
But for me @Erel the real question remains which is why does Canvas.MeasureStringWidth work to produce the correct size of text but Canvas.MeasureStringHeight does not seem to work?

 

Thanks for the clarification.
