I am making an android application where i got a seekbar for some music. I got the seekbar to show the music playing status, where i currently am in the music playback. But how can i setup a listener so that i can say that the mediaplayer would play a specific place on a track? I know the code for setting the play time in mediaplayer, but how can i handle the click events from seekbar? like onClick() or anything similar?

You’ll want to implement
SeekBar.OnSeekBarChangeListener, then implement the onProgressChanged method.This is called when the progress is changed (eg a user click somewhere on the seekbar), and will provide you with the new position.
Example:
Don’t forget to register the OnSeekBarChanged listener with seekBar.setOnseekBarChangeListener
