View view = snack.getView();
FrameLayout.LayoutParams params =(FrameLayout.LayoutParams)view.getLayoutParams();
params.gravity =  Gravity.CENTER_HORIZONTAL | Gravity.TOP;
// calculate actionbar height
TypedValue tv = new TypedValue();
int actionBarHeight=0;
if (getTheme().resolveAttribute(R.attr.actionBarSize, tv, true))
{
    actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
// set margin
params.setMargins(0, actionBarHeight, 0, 0);

view.setLayoutParams(params);
snack.show();
