Placeholder text (design process only) in Android layout?

Question

Is it possible to create placeholder text that is only visible during the layout design process in Android Studio?

For example, say I have 2 TextViews in a linear layout that are going to be dynamically populated. During the design phase, I use placeholder text to ensure I get padding and such correct. I often forget to remove placeholder text, so during loading of the new data, the old data will appear for a split second... looks tacky.

It would be cool if there was a field similar to android:placeholderText="This is placeholder text" that would only display in the preview. There isn't such a thing that I've happened to have missed is there?

Yes it is (these days), and I believe that this is probably what you're looking for:
