Answer 1

Above error due to passing wrong casting params :- because some time you set programattically parameter for linear layout but when you doing getLayoutParams() then it some time gives parent layout reference then it is gives above error .

FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) parentLayout.getLayoutParams();
        int leftMargin = (int) getResources().getDimension(R.dimen.exclusion_card_margin_left_right);
        int rightMargin = (int) getResources().getDimension(R.dimen.exclusion_card_margin_left_right);

        params.setMargins(leftMargin, 0, rightMargin, 0);
        parentLayout.setLayoutParams(params);
