输出：com.mahdi.roomdatabase.data.entity.Cantact.@85c7ce6

Codes:

    Observer<DatabaseNew> observer = new Observer<DatabaseNew>() {
        @Override
        public void onChanged(DatabaseNew databaseNew) {

            searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    getDatabasefromDb(query);
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    getDatabasefromDb(newText);
                    return true;
                }
            });

        }
    };
    mainModel.getLiveData().observe(this, observer);
}

private void getDatabasefromDb(String searchText) {
    searchText = "%" + searchText + "%";
    contacts=databaseNew.getDatabaseInfo(SearchActivity.this, searchText);

    arrayAdapter = new ArrayAdapter(SearchActivity.this, android.R.layout.
            simple_list_item_1, contacts);
    listView.setAdapter(arrayAdapter);
}

public List<Contact> getDatabaseInfo(Context context, String Query) {
    return getContactDAO(context).getContactList(Query);
}
