Set Margin on RecyclerView programmatically

Question

I need to set the top margin on a RecyclerView programmatically, but I get this exception:

java.lang.RuntimeException: Unable to resume activity java.lang.Cla

I am also facing this type of issue, Use below code to handle margin issue of recyclerview.

    ViewGroup.MarginLayoutParams marginLayoutParams=
    (ViewGroup.MarginLayoutParams) recyclerView.getLayoutParams();

    // here i try to set only top margin, Get dimension from dimension file.
    int topMargin =  getResources()
    .getDimensionPixelSize(R.dimen.top_margin);

    marginLayoutParams.setMargins(marginLayoutParams.getMarginStart(),
    topMargin, marginLayoutParams.getMarginEnd(), marginLayoutParams.bottomMargin);

    recyclerView.setLayoutParams(marginLayoutParams);
