TLDR (too long didn’t read)
- When trying to get the height of a Android device, make sure you do it in an pixel density independent way:
- correct way to get height:
val displayMetrics = Resources.getSystem().displayMetrics
val heightPixels = displayMetrics.heightPixels //exact physical pixel amount(different on certain devices)
val density = displayMetrics.density //density multiplier
val pixelDensityIndependentHeight =heightPixels / density
val height = Resources.getSystem().displayMetrics.heightPixels
//as previously mentioned, this height will change depending on the
// device's pixel density and it can really mess up your UI
Why does this matter?
- I have created THIS UI FEATURE which relies heavily on my app being able to understand the height of the device and dividing it into 3 sections. If I don’t use the height in a
pixel density independent way(unfortunately I did this) the UI will look different on different devices. Which obviously is not ideal - So to summarize, make sure you are conscious of pixel densities in your UI
Conclusion
