android - How to make toast (method not resloved) -

toast.maketext(this, "note deleted", toast.length_short).show(); 

why method cannot resloved? following wrong format?

1) sure have imported toast class

2) if it's inside activity, code work.

3) if it's inside fragment, need context show this:

toast.maketext(getactivity(),"note deleted",toast.length_short).show();
