android-mediaplayer

问题 I've created a dialog for selecting a notification sound for an app. I'm querying the notification sounds by getting a cursor from the RingtoneManager: RingtoneManager manager = new RingtoneManager(this); manager.setType(RingtoneManager.TYPE_NOTIFICATION); Cursor cursor = manager.getCursor(); I then store the full path to it by concatenating the sound path with the name. This works fine when I set the selected sound as the notification sound but I can't get media player to play it on

问题 Basically, we want to build a paged horizontal scroll view with one video player on each page; Video should auto-play and auto-pause/stop when page focus is changed. So I decided to use a ViewPager to show video Fragments. Each fragment has its own SurfaceView and MediaPlayer for video playing.

问题 I am relative new to Android development. I am working on an app where it is a specific client requirement that I have a scrollable list of videos. These videos must be playable within the scrolling list as embedded views. My first thought was to use VideoViews in a ListView and use a custom ArrayAdapter to instantiate the VideoViews.
