I am currently working on an android app, and I’m having an issue with displaying XML layout In Android Studio, everything looks fine, but in the VM it doesn’t look too good.
This is how it looks in Android Studio:
And here is how it looks like when it’s displayed in VM:
I should probably mention that it is supposed to be a pop up window
Here is XML code:

Answer
Try adding,
app:layout_constraintEnd_toEndOf="@+id/TimerValluesBackground"
to your last TextView(@+id/secondValue) component.
