Glitch while rendering the RecyclerView list items

Everything is working fine in the weather app. Only thing is that, after I press the "Hour" button, the list shows up but instead of the icon and summary label being laid out evenly between the time and temperature labels, both the icon and summary label overlap on top of each other. The problem fixes itself if I scroll down; the views return to normal and when I scroll back up, those "glitched" items are back to normal. I'm using an emulator running the old Android v4.1, so what could have gone wrong?

I figured it out. The one line that says android:layout_centerInParent="true" in the ImageView is what was causing the problem. I erased it and it went away.
