How can I use SeekBar's OnSeekBarChangeListener to seek to a specific point in a MediaPlayer object?
I have some Android code to stream an audio file from the internet and play the stream after 10 seconds.
I am using a SeekBar to view the buffering status and playing status. I want to play the audio starting from the middle of the buffered stream. For that, I move the SeekBar point to the middle, but I cannot play the audio from the middle; it will go back and start from the beginning. How can I get the seeked position and how can I play the audio from that particular position?
Here is my SeekBar code. How can I make this code use the OnSeekBarChangeListener properly?
seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
// TODO Auto-generated method stub
if (arg2 && mediaPlayer.isP开发者_运维知识库laying()) {
//myProgress = oprogress;
arg1=mediaPlayer.getCurrentPosition();
mediaPlayer.seekTo(arg1);
}
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
});
arg1=mediaPlayer.getCurrentPosition();
mediaPlayer.seekTo(arg1);
You are forcing the player to seek to the current position, and not to the positon retuned by the Seekbar
Remove the line: arg1=mediaPlayer.getCurrentPosition();
and it should work. Of course after MediaPlayer.prepare()
set SeekBar.setMax(MediaPlayer.getDuration())
, so seeking will be accurate.
I think you have to make a thread... I have some code given below which you can try to implement.
public void run() {
try
{
while(song1.getDuration()!=song1.getCurrentPosition())
{
skbar.setProgress(song1.getCurrentPosition());
//bStop.setText(song1.getCurrentPosition());
}
if (song1.getDuration()==song1.getCurrentPosition())
Log.v("log","Sanket");
t.suspend();
}
catch (Exception e)
{
Log.e("log",e.toString());
}
}
