Hi guys, do you know how to use properly cardView. I am trying something like this:

cardView(){
    lparams(height = wrapContent, width = matchParent){

    }
}

And it looks like there is no lparams here. But if I do something like

verticalLayout(){
    cardView(){
        lparams(height = wrapContent, width = matchParent){

        }
    }

}

it is there. So it looks like I can’t use cardView like root view?

What do you mean? No such method? That’s because lparams methods are declared inside _LinearLayout, _RelativeLayout, _FrameLayout and so on. You can’t use lparams on any root view, try using explicit layoutParams = SomeLayout.LayoutParams(...).

How you mean I can’t use lparams on any root view? I can use it with
linearLayout(). So, why can’t I do the same with cardView ?

[mkojadinovic]

Oh, I understand now. There is no defined lparams method for cardView, but I can use layoutParams explicitly

Thanks. 👍

It’s because the lparams is in reference to the a view’s parent view. If there is no parent view, you can’t use lparams for any view.

However, you can specifically set layoutParams, as you mentioned. If CardView were inside another viewgroup, you could use lparams.
