Since we already have an item_chooser_dialog_row.xml:
https://cs.chromium.org/chromium/src/chrome/android/java/res/layout/item_choo...
I am wondering if that one can be reused by adding the ImageView to it instead
of creating a item_chooser_dialog_row_with_icon.xml? I noticed that there is
RelativeLayout:
https://cs.chromium.org/chromium/src/chrome/android/java/res/layout/web_notif...

And can set element.setVisibility(View.GONE); to hide a view, and
android:layout_alignWithParentIfMissing to make a view to take the missing
view's space.

If so, when the "connected"/"paired" status need to be added to the row, it will
be easier.
