Android Question Screen Size

[Mehrzad238]

I know that there is a lot of question about screen size on this forum but I need to know which one is the right one to use
my phone is Xiaomi Redmi 8 with a 6.2-inch screen size but the result says another thing!

    Dim lv As LayoutValues
    lv = GetDeviceLayoutValues
    Log( Sqrt(Power(lv.Height / lv.Scale / 160, 2) + Power(lv.Width / lv.Scale / 160, 2)))
    Log(Sqrt(Power(800 /160, 2) + Power(480 / 160, 2)))
    
    Dim r As Reflector
    r.Target = r.GetContext
    r.Target = r.RunMethod("getResources")
    r.Target = r.RunMethod("getDisplayMetrics")
    Dim xdpi As Double = r.GetField("xdpi")
    Dim ydpi As Double = r.GetField("ydpi")
    
    Dim lv As LayoutValues
    lv = GetDeviceLayoutValues
    Log( Sqrt(Power(lv.Width / xdpi, 2) + Power(lv.Height / ydpi, 2)))

What are you trying to do? accessing xdpi and ydpi is wrong unless you are building a "ruler" app.

It doesn't work like this. If you asked a question and found the answer then post it.

I have problems with the design and one of them is screen size, for example, I have a 6-inch screen device works just fine when I am going on 5.5-inch views going to each other and I thought that this could help me with that, can anyone guide me with this?

Yes. The above is not relevant. You should use anchors and designer script. Watch the visual designer video tutorial: https://www.b4x.com/etp.html
