Android Question Display problem on different devices

[yaniv hanya]

I am developing an app that is supposed to run on multiple screen sizes,
so the size of the controls I calculate in a designer script.
On some devices everything works well, but on one device it comes out twisted.
Do you have any idea why?

This is how it looks on lenovo tab 7

This is how it looks on samsung j2

and This is how it looks on LG g6

Do you have any idea why?
the line in the designer that sets the text size are

timeLb.Top=mainPnl.Height*0.10
timeLb.Height=mainPnl.Height*0.18
timeLb.TextSize=mainPnl.Height*0.10

hebDateLb.Top=mainPnl.Height*0.27
hebDateLb.Height=mainPnl.Height*0.1
hebDateLb.TextSize=mainPnl.Height*0.04

fDateLb.Top=mainPnl.Height*0.34
fDateLb.SetLeftAndRight(0,100%x)
fDateLb.Height=mainPnl.Height*0.1
fDateLb.TextSize=mainPnl.Height*0.04

1. Please use [code]code here...[/code] tags when posting code.
2. Linear scaling of the layout is a mistake in most cases. Better to use anchors and remove all of this code.
3. This line is wrong:

fDateLb.TextSize=mainPnl.Height*0.04

Just delete it.

It is wrong because Panel.Height value depends on the device scale and text size is scaled internally (you don't use dip units when setting the text size).

Is there no way to calculate the size of the letters I need while running.
There are other labels that are created only at runtime, according to changing information,
the size of which I calculate only by screen size so I can determine the textsize in them?

These routines might help:.

SizeToFit routines (MeasureStringWidth, MeasureStringHeight, MeasureMultilineStringHeight)

Routines to adjust a label to fit its text/adjust text size to fit a label: * SizeToFitWidth - given a width (and using the label's font), adjust the label's height * SizeToFitHeight - given a height (and using the label's font), adjust the label's width * SizeFontToFit - given some text for the...
