如何在活动中显示Snackbar消息？

<androidx.coordinatorlayout.widget.CoordinatorLayout
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Your activity content here -->

</androidx.coordinatorlayout.widget.CoordinatorLayout>

CoordinatorLayout coordinatorLayout = findViewById(R.id.coordinatorLayout);
Snackbar snackbar = Snackbar.make(coordinatorLayout, "Snackbar message", Snackbar.LENGTH_SHORT);

snackbar.setBackgroundTint(Color.BLUE);
snackbar.setTextColor(Color.WHITE);

snackbar.setAction("Undo", new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Perform action when the "Undo" button is clicked
    }
});

snackbar.show();
