How do you implement a snackbar that has the button at the bottom?

Question

Does anyone know how to add a button like this, and keep it showing?

This is my code:

.JAVA

private Button btnNewUser;
private LinearLayout linearLayoutContainer;
//OnCreate....
btnNewUser = findViewById(R.id.newUser);
linearLayoutContainer = findViewById(R.id.linearLayoutContainer);
btnNewUser.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Snackbar
                .make(linearLayoutContainer, "Message in Snackbar!", Snackbar.LENGTH_LONG)
                .show();
            }
        });
