Android Question Button text not scaling correctly

[ginsh]

Hi,

I have tried the below code and it works fine with Samsung S5 even if I increase the font size on the phone. But when I am testing the same in Samsung S6 & S7 it is not working. The text on the buttons are not scaled correctly.

Please anyone help me out.

Sub Process_Globals
   Dim access As Accessiblity
End Sub

Sub Globals

End Sub

Sub Activity_Create(FirstTime As Boolean)
   ResetUserFontScale(Activity)
End Sub

Sub ResetUserFontScale(p As Panel)
   For Each v As View In p
     If v Is Panel Then
       ResetUserFontScale(v)
     Else If v Is Label Then
       Dim lbl As Label = v
       lbl.TextSize = lbl.TextSize / access.GetUserFontScale
     Else If v Is Spinner Then
       Dim s As Spinner = v
       s.TextSize = s.TextSize / access.GetUserFontScale
     End If
   Next
End Sub

Could you post a small project, as a zip file, showing the problem so we could test it.

Hi,

Find attached the simple test code. I have tested this code in S6 & S7 and the
text on the buttons are not showing completely. But works fine with Samsung s5.

The problem is that the height of 28 of the buttons is too small.
Set their height to 40 and it will work OK !

Hi Klaus,

Thanks for your advice. What if i want to have a smaller size button?

You need to decrease the TextSize !
For a height of 28dip you need a TextSize of 8 to get the text displayed correctly.
To me, 28 dip on my Samsung S6, looks awfully small.

For a height of 28dip you need a TextSize of 8 to get the text displayed correctly.

Is there a specific ratio or formula for this so that we could follow this as a guideline while developing app.

You can also use java object to remove the padding of the button to make more text fit in. Search the forum for button padding.
