How to dismiss a Snackbar using its own Action button?

Android design support library now includes support for Snackbar.

I've used the following code to create one:

Snackbar.make(findViewById(R.id.root_layout), result, Snackbar.LENGTH_LONG)
        .setAction("Dismiss", new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        }).show();

The snackbar can be dismissed by a swipe. However, I also want to dismiss it using its own Action Button (created using the setAction function).

However there doesn't seem to be any function available that can do that.

For Java,

The .make method returns a Snackbar object. Save an instance of that object by making it final. Then, in the onClick(), call .dismiss:

final Snackbar snackBar = Snackbar.make(findViewById(android.R.id.content), "Snackbar Message", Snackbar.LENGTH_LONG);

        snackBar.setAction("Action Message", new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Call your action method here
                snackBar.dismiss();
            }
        });
        snackBar.show();

For Kotlin,

        Snackbar.make(
            findViewById(android.R.id.content),
            "Snackbar Message",
            Snackbar.LENGTH_INDEFINITE
        ).setAction("Action Message") {
            // Call action functions here
        }.show()
