Yes, its possible.
First you should get the youtube channel's videos. You can use httputils2 to download the channel's page, and then parse the content. The channels provide a little rss, that gives you the last 25 videos. You could also work with youtube lists (it can be a list from your youtube user, and it can contain all the videos of the users you want, but make sure its a public list), with this you don't have 25 limit videos as the channel's rss, but you will have to parse the html page as well.
Once you got everything parsed, you can populate the listview with, for example, the title of the videos, and when an item is clicked, you can start playing the video.
