[android-developers] Re: AutoScroll ListView at specified intervals without user intervention
I'm trying to automatically scroll the list view based on the playing of an audio file. The listview items will have English translation of what is being played in the audio which will be in a foreign language. So as the audi progresses, i need to keep the listview scrolling down. I will maintain a mapping file with timestamps to directly the scroll.

Although I'm not sure exactly what you are trying to accomplish. For example you say I want to show the first item .., but being a ListView you will probably see much more than one item.

Thanks for your input. On Jan 28, 10:55 am, YuviDroid yuvidr...@gmail.com wrote: Ok, now it's clearer :) The two links I gave you should help with auto-scroll part. With the time intervals you might use a Timer (http://developer.android.com/reference/java/util/Timer.html), or make use of the AlarmManager (http://developer.android.com/reference/android/app/AlarmManager.html). I'm not sure though if any of these will be precise enough, so that you remain perfectly in sync with the audio being played. Maybe there are some classes/methods that allow to do that better directly in the MediaPlayer (or SoundPool).
