How to show SnackBar in Android

SomeClass.java

Snackbar.make(parentLayout, "Some Message", Snackbar.LENGTH_LONG) //you can just to pass built-in layout android.R.id.content
        .setAction("Action", new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //handle click here
            }
        })
        .show();

//P.S. Usage built-in layout android.R.id.content:
//getActivity().findViewById(android.R.id.content);
