Snackbar action getView()

in my Activity I have implement OnClickListener interface

MainActivity extends AppCompatActivity implements View.OnClickListener

init snackbar like this:

snackbar = Snackbar.make(view, R.string.msg, Snackbar.LENGTH_LONG);
snackbar.setAction(R.string.action_undo, this);

but I cannot handle it on implemented OnClickListener interface method

@Override
public void onClick(View v) {
    // this not work!
    // snackbar id is different from snackbar action id
    if (v.getId() == snackbar.getView().getId()) {

    }
}

Someone know how to get action view from snackbar?
