我遇到了一些在片段中显示snackbar的问题。我可以为一个Activity设置一个很好的snackbar，但是当我在片段中尝试时，它就不会出现，也没有错误。

小吃店内碎片

Snackbar snackbar = Snackbar.make(rootView, "Snackbar test", Snackbar.LENGTH_SHORT);
View sbView = snackbar.getView();
TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(Color.YELLOW);
snackbar.show();

分片中的rootView

rootView = inflater.inflate(R.layout.fragment_possible_recipes, container, false);
