How to add livedata to spinner

[towertech]

How can we use livedata in spinners? I have the following:

LiveData<List<Site>> sites = SiteDatabase.getInstance(this).siteDao().getAllSites();

Spinner spinner = findViewById(R.id.spinnerSites);
**What Goes Here!!*** adapter = new ArrayAdapter<Site>(this, android.R.layout.simple_dropdown_item_1line, sites);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);


Not sure how to proceed..

Thanks!!
