Accessible Seek Bar?

[J.J. Meddaugh]

I notice some Android apps have included an accessible seek bar where you can slide left and right on the D-pad to move the audio position.

I am talking to a dev interested in adding this but they need a bit of guidance on how to accomplish this. Would someone be able to point me in the right direction so I can help the dev?

Thanks much.

I believe that works with the default seek bar: http://developer.android.com/reference/android/widget/SeekBar.html

As was already stated, the default seekbar is already fairly accessible. It may or may not be necessary to call setKeyProgressIncrement(int) to indicate how much the arrows should change the seekbar's current position:

http://developer.android.com/reference/android/widget/AbsSeekBar.html#setKeyProgressIncrement%28int%29

Not sure if there is a default. Also, it'd be nice to call setContentDescription() on the seekbar to give an accessible indicator of how far along it is. See, for instance, the seekbar in the iBlink Radio app for an example of this technique.

Thanks both of you. He likely didn't have the bar focusable, and I've passed along the info about the content description as well.

 

The app, BTW, is Audio Log HD and is otherwise a really cool recorder for high-quality wav files.
