android - How can I get height of ImageView in RecyclerView.Adapter -

i'm using recyclerview , staggeredgridlayoutmanager, displaying cardview imageview , textview in it. images should square, in layout resource file set android:layout_width="match_parent" , need set height equal width. tried in adapter, extends recyclerview.adapter in onbindviewholder method, getmeasuredwidth returning 0. i'm setting adapter recyclerview in activity's onresume method. how can this?

i suppose case when onresume method finished, image not set on ui screen yet because cost time. bitmap asynchronous framework might you, xutils or [universalimageloader][1]. can scale when bitmap downloaded completely, or can image width server, there might other solutions too.
