Display image in Android Studio but not on the phone

Question

As you can see below, this shows Android Studio:

However, when I run this application on my phone, viewing the list shows only a blank image (ie a space) above it, where it should be "somewhere above the rainbow."

View mode works great. It consists of one image and two textual representations. (This representation of the image works if it helps). If any of this possibly interferes, I will post the code here, but it's hard for me to believe.

The only thing I did not know about was to use the relative view when defining the cells to represent the list in a separate XML file. I don’t understand why not, but this is the only thing I could think of.
