It works for me!

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/temperatureLabel"
        android:layout_alignTop="@+id/circleImageView"
        android:layout_alignBottom="@+id/circleImageView"
        android:layout_alignLeft="@+id/circleImageView"
        android:layout_alignRight="@+id/circleImageView"
        android:gravity="center|center_vertical|center_horizontal"
        android:textColor="#f25019"
        tools:text="100"
        android:layout_alignParentRight="false"
        android:layout_centerInParent="true" />

it works due to "android:layout_centerInParent="true" "

Thank you!

Tried that and it didn't work, fussed with it some more and I just realized I had android:layout_centerInParent setting to an @id instead of a "true". Since I had added it into the XML, didn't catch it till I noticed the field was still blank in the design view properties. Still don't know why it worked regardless on the android studio emulator and not Genymotion, but now they are both working properly.

The center in parent didn't work for me. I found out it worked in the Android Emulator, but not the Genymotion. Anyone else experiencing this or know a reason why this might be the case?

I'm also seeing the results on the right in my Genymotion emulator, although I'm not sure why. Setting android:layout_centerInParent to true fixed it for me.

There's some additional text views in here since I proceeded through the course.

The Daily Forecast XML:
