Expand and collapse CardView

Question

What is the proper way to expand a CardView?

Answer 1

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.

Answer 2

If you are using CardViews inside a ListView or RecyclerView see my answer for recommended way of doing it: RecyclerView expand/collapse items

If you are just using CardView the do this in your on onClickListener of cardview:

TransitionManager.beginDelayedTransition(cardview); detailsView.setVisibility(View.VISIBLE); 

By default keep the visibility of your detailsView to be GONE in your xml.
