Cardview width not matching parent

Question

I need to create a Recyclerview. For that I have created an cardview model to be displayed in a recyclerview. Even though i have given match parent to the layouts, the width of cardview is not fitting the parent. Its width is showing approximately up to half of the screen(not matching parent) Do anyone can support?.please advise better way to do this.

You've provided layout of item. Please also provide layout that has the RecyclerView as your item layout seems to be just fine. — ror, Jun 24 '20 at 05:20
I guess you might have set your recycler view width to wrap content or some specific width change it to match_parent — AgentP, Jun 24 '20 at 05:22
Change the `inflate()` call in `onCreateViewHolder()` to `inflate(R.layout.downloads_elements, parent, false)`. I would also mention that you do not want to use `getBaseContext()` for the `LayoutInflater`. Just use the `Activity` itself; otherwise, your items won't have the appropriate themes and styles applied. — Mike M., Jun 24 '20 at 05:59
@MikeM. Width is getting to match parent now. But only one item is showing in Recyclerview — Irfan, Jun 24 '20 at 06:03
Actually, that `` is rather pointless if it's only ever going to have one child. You could get rid of that, and just make the `` the root. — Mike M., Jun 24 '20 at 06:06
