Expand and collapse CardView

Use an expandable list view with cardview

or even

You can use wrap content as height of cardview and use
textview inside it below title, so on click make the textview visible
and vice-versa.

but isn’t it bad design ?

nope it isn’t if you give some transition or animation when it’s expanded
or collapsed

If you want to see some default transition then just write android:animateLayoutChanges=”true” in parent layout.
