Android Question [Problem] Different devices different text sizes

[Juan Luis Lopez]

Hi i have some problems with sizes in different devices:

Here is the script from designer i wrote:

'All variants script
AutoScaleAll
iconsize=25%x
logosize= 30%x
margenV=5%y
IconMargin= IconSize*0.25
'Tamaños
ImLogo.Width=logosize

imVer.Height=60%x
imVer.Width=2dip

BtnOfertas.Width= iconsize
BtnOfertas.height= iconsize
BtnPinchos.Width= iconsize
BtnPinchos.height= iconsize
BtnLocation.Width= iconsize
BtnLocation.height= iconsize
BtnCodigos.Width= iconsize
BtnCodigos.height= iconsize

'Posiciones

imVer.Top= ImLogo.top + ImLogo.Height + MargenV
imVer.HorizontalCenter=50%x

ImHor.Top= imVer.Top+imVer.Height * 0.5

'Botones
   BtnOfertas.Width=IconSize
   BtnOfertas.Height= IconSize

ImWifi.height= 0.45*IconSize   
ImWifi.Left=imShare.Left + ImWifi.Width+  0.40 * ImWifi.width

And theese are the results in my different devices:
Hay can i put the label text size to be the same size in all of them i mean, above the sandwich icon in tablets the label is like 1/3 wide of the image of the sandwich but in the mobile phone its like 2/3 wide. and the text looks smaller in tablets in comparison to the screen than in the phone...
How can i fix it??
Any idea??
thanks!!

Tablet 10.1"

Tablet 7"

Yourssue is related to screen resolution, different devices, even if they have the same screen width and height, can have different resolutions (ie 72dpi,96dpi,etc). Font sizes are DPI dependat. The best way to ensure your text size, is to adjust your font size to your label height, measuring the "physical" size...
Take a look at the canvas object, there is a method to obtain a given string's physical height, depending on the font, and font size.
It shouldn't be to difficult to create a loop to get the desired font size

Are you using multiple variants? It is better not to use multiple variants and let AutoScaleAll increase the text size.

Hay can i put the label text size to be the same size in all of them

What exactly do you want !
The text size in your 3 devices IS the same, you defined TextSize = 16 !
As the dimensions of the icons on a 10'' screnn a double of those on a 5'' screen the text looks small on the big screen.
If you want the text proportional to the screen size you must calculate the ratio between the referenc screen size and the real screen size.
You are using AutoScaleAll at the beginning and change evrything after it, so in this case it is not useful becaus you change all the results from AutoScaleAll.
But, to change the TextSize you could use AutoScaleAll with an AutoScaleRate(1), and keep the other changes after it, not really elegant but possible.

 

[Juan Luis Lopez]

So i should put the autoscaleall sentence at the end of the script??

Erel im using only one variant.

Im trying and ill tell you the result

So i should put the autoscaleall sentence at the end of the script??

No.
It depends on how you want to manage the TextSize properties.
You haven't told us yet how you want the text sizes.
If you manage the text sizes in the script you can uncomment AutoScaleAll.

 

[Juan Luis Lopez]

Ok what i want is that the text look proportional in all devices. I use my galaxy express to test the apps. I use percentages to set positions and sizes of the controls. What i see is that te controls resize well because i use percentages of the screen size so they look proportional i nall devices. But the text size doesnt resize. What i want is that if my sandwich icon height is 5 times the height of the text in my phone, in my tablet it should be the same proportion.

Understand me? Sorry for my english

 

[klaus]

Understand me?

Yes, that's what I suspected, but your explanation is now different from the first post (... same size ...) and the reason why I asked it again to be sure that this is what you want.

What is the screen size of your reference layout ?
Use this in the Script:

'AutoScaleAll     ' uncomment AutoScaleAll
ReferenceSize = 5
TextSizeRatio = ActivitySize / ReferenceSize
'
'
lblPinchos.TextSize = 16 * TextSizeRatio

You need to replace 5 by the screen size (in inches) of your reference layout.
And multiply the TextSize properties of the other views.

 

[Juan Luis Lopez]

Sub EnBaseAlGalaxy(Size As Double) As Int
Dim RealInches As Double
Dim BaseInches As Double
Dim Ratio As Double
RealInches= GetDeviceLayoutValues.ApproximateScreenSize
BaseInches=4.589389937671455
Ratio = RealInches/BaseInches
Return Size * Ratio
End Sub

Now I use this to resize textsizes in other devices to look like the same proportion as in my Galaxy phone.
its quite accurate . thanks klaus!

 

[klaus]

You should use
Sub EnBaseAlGalaxy(Size AsDouble) As Float
instead of
Sub EnBaseAlGalaxy(Size AsDouble) As Int
because TextSize is a Float variable.

I think that BaseInches = 4.6 would be enough .
