How to show Snackbar when Activity starts?

Question

I want to show android Snackbar (android.support.design.widget.Snackbar) when the activity starts just like we show a Toast.

Answer 1

Simple way to show some text:

Snackbar.make(view, "Sample Text", Snackbar.LENGTH_SHORT).show();

and to show text with button:

Snackbar.make(view, "Sample Text", Snackbar.LENGTH_SHORT).setAction("Ok", new View.OnClickListener() {
            @Override 
            public void onClick(View view) {

            } 
        }).show();
