The Scots finished their World Cup qualifying campaign with victories over Macedonia and Croatia, raising hopes they will give a better account of themselves in the Euro 2016 qualifiers.
Hanley played in Friday's match with USA at Hampden, and he is looking forward to facing Norway on Tuesday in Molde.
"We need to head to Norway and hope we can keep our wee run going," Hanley said. "It's all about momentum as we prepare for the next European Championship campaign.
"I think there is a difference in the mood in the camp from a few months ago. Before when we went into these games like Croatia away, we had nothing to lose.
"We were always positive but that's not the same as believing you will win. But now that we are on the back of a wee run and our performances have picked up, we can take a bit of confidence into the games."
Meanwhile, striker Steven Fletcher and versatile Charlie Mulgrew have both been ruled out of the Norway friendly.
Celtic ace Mulgrew, who has been deployed in defence and midfield for club and country, sustained a knee injury in the 0-0 draw with USA.
The 27-year-old has been given permission to return to Celtic, with consideration being given to the club's Champions League schedule.
Fletcher has also left the squad, after his recent return to action with Sunderland following a shoulder problem.
