In listview I click an audio to start but when I scroll I see other audios has stared too

I have a ListView of audios which have seek bar in it . When I click the play button of one of audios, it starts but when I scroll down I see that some other seekbars are also playing and when I scroll up again the first item that I clicked is no paused. I have searched a lot and it seems that there is a problem with position of item in list , the only solution I found was to use viewholder in adapter but it didn't work . does any one have a solution? thanks.
public class AudioAdapter extends ArrayAdapter<News> {
Context context;
boolean isPLaying = false;
public AudioAdapter(Context context, ArrayList<News> array) {
super(context, R.layout.list_item_news, array);
this.context = context;
}
public static class ViewHolder {
TextView txtTitle;
SeekBar seekBar;
TextView audioDuration;
ImageView btnPlayStop;
MediaPlayer mp;
Handler seekHandler;
int audioCurrentPosition;
}
public View getView(final int position, View convertView, ViewGroup parent) {
final News news = getItem(position);
final ViewHolder viewHolder;
if (convertView == null) {
viewHolder = new ViewHolder();
convertView = LayoutInflater.from(getContext())
.inflate(R.layout.list_item_audio, parent, false);
viewHolder.txtTitle = (TextView) convertView.findViewById(R.id.audioTitle);
viewHolder.seekBar = (SeekBar) convertView.findViewById(seek_bar);
viewHolder.audioDuration = (TextView) convertView.findViewById(R.id.txtDuration);
viewHolder.btnPlayStop = (ImageView) convertView.findViewById(R.id.btnPlayStop);
viewHolder.mp = new MediaPlayer();
viewHolder.seekHandler = new Handler();
convertView.setTag(viewHolder);
}
else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.txtTitle.setText(news.getTitle());
viewHolder.mp = MediaPlayer.create(context, R.raw.team);
viewHolder.audioCurrentPosition = news.getAudioPosition();
viewHolder.mp.seekTo(viewHolder.audioCurrentPosition * 1000);
viewHolder.audioDuration.setText(ms);
viewHolder.btnPlayStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if ( !isPLaying) {
viewHolder.mp.seekTo(viewHolder.audioCurrentPosition * 1000);
//play
isPLaying = true;
viewHolder.btnPlayStop.setImageResource(ic_media_pause);
viewHolder.mp.start();
viewHolder.seekBar.setMax( viewHolder.mp.getDuration() / 1000);
((Activity) context).runOnUiThread(new Runnable() {
#Override
public void run() {
if ( viewHolder.mp != null && viewHolder.mp.isPlaying()) {
int mCurrentPosition = viewHolder.mp.getCurrentPosition() / 1000;
viewHolder.seekBar.setProgress(mCurrentPosition);

}
}
});
} else {

#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if ( viewHolder.mp != null && fromUser) {
//Change the seekbar with finger
viewHolder.mp.seekTo(progress * 1000);
viewHolder.audioCurrentPosition = progress * 1000;
}
}
});
viewHolder.mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
//When mediaplayer finishes
isPLaying = false;
viewHolder.btnPlayStop.setImageResource(ic_media_play);
viewHolder.audioCurrentPosition = 0;
}
});
return convertView;
}
}

Since you are using ViewHolder pattern, your views are being recycled and hence, your playing-indicator gets reused too...

Release your old MediaPlayer when you a new instance is started. For example:
protected void mediaplayerMethod(String filepath) {
Log.d(TAG, "mediaplayerMethod audio file path " + filepath);
if(mp != null){
mp.release();
}
mp = null;
mp = new MediaPlayer();
mp.setOnCompletionListener(AudioAdapter.this); // Important
seekBar.setOnSeekBarChangeListener(AudioAdapter.this);
utils = new Utilities();
playSong(filepath);
}
EDIT 1
You can try the below code
public class SoundTest extends Activity {
private ListView lv1;
private String lv_arr[]={"test 1","test 2","test 3","test 4","test 5"};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lv1=(ListView)findViewById(R.id.ListView01);
lv1.setAdapter(new ArrayAdapter<String>(this,R.layout.list_item, lv_arr));
lv1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
if (lv1.getItemAtPosition(position)=="test 1") {
MediaPlayer mp = MediaPlayer.create(getApplicationContext(),R.raw.sound1);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
}
if (lv1.getItemAtPosition(position)=="test 2") {
MediaPlayer mp = MediaPlayer.create(getApplicationContext(),R.raw.sound2);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
}
//And the rest of the audio 3,4,5.
}
});
}
}
The global variable MediaPlayer needs to be set private static. This has caught me several times.

How to implement the prev and next button in second activity using Simpleadapter in Fragment?

I integrated a Radiochannel list in a Fragment using Simpleadapter. Now I want implement the prev and next button in a second activity to switch between the List.
Now I passed data using Bundle, but by clicking the nextButton i can just increment the position one time, at the second click the app stops.

Use this lines of code:
MediaPlayer mp = new MediaPlayer();
playMySong(String songPath)
{
mp.reset();
mp.setDataSource(songPath);
mp.prepare();
mp.start();
}

Don't create MediaPlayer instance for individual row of list. Let it be property of Adapter because this will help us to detect whether this media player is playing some song currently or not
So do this
public class MyAdapter{
private MediaPlayer mediaPlayer=new MediaPlayer();// I am ignoring exact constructor
//now in your getView method do like this
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
//.............prev code
holder.imgPlay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
holder.imgPause.setVisibility(View.INVISIBLE);
holder.imgPlay.setVisibility(View.VISIBLE);
}else{
mp.reset();
mp.setDataSource(Uri.parse(Environment.getExternalStorageDirectory().getPath()+path + fileName));
mp.prepare();
mp.start();
//set other things
}
}
});
//......some code below
}
}
Hope this will help you !!!!

As you progress in your application, you will find out that there would be other activities or fragment which may try to play some music and you will fall in same circumstances, Otherwise you might think that you just want to stop music as you come out of this list activity.
instead of going though the hustle of managing the instance of MediaPlayer make just make it once in the Application inside a class which will handle your business for playing the music, in your current case what is happening is the MediaPlayer API of android keep getting the request for playing music and by no means that these API can't handle multiple request so they will keep on playing as you command them,
in your custom class you gotta check if your MediaPlayer instance is still playing or not like this...
player.isPlaying()
if it is playing than stop it, like this
player.stop()
and give it some new data what you want it to play.

correctly displays a seekbar in custom adapter

I have a list in which each element on a player. When I click on "start" and a song starts playing strip seekbar starts moving. when click on the "stop" the song stops playing and the strip stops. But if while moving the strip I scroll list and it goes off the screen, it starts to move another strip that is on the same position in the visible area of the screen.

EDIT:
I added geter and seter in recordBean
public int getSeekPos() {
return SeekPos;
}
public void setSeekPos(int seekPos) {
SeekPos = seekPos;
}
and
holder.seekBar.setProgress(recordBeans.get(position).getSeekPos());
holder.date.setText(" " + recordBeans.get(position).getDate());
and
#Override
public void onProgressChanged(final SeekBar seekBar, final int i, boolean b) {
if (b && (Integer)seekBar.getTag()==global_position) {
// mediaPlayer.seekTo(i);
recordBeans.get(position).setSeekPos(i);
}
}
but I think it left something extra in my code

The list item is being recycled when it leaves the screen.
You could try to call this in getView:
holder.seekBar.clearFocus();

This is a tricky process, but you can do this in the following way, as I have seen that you have created a List of RecordBean class. So what you can do is you have to create a Getter Setter in RecordBean for storing the position of you SeekBar like:
public void setSeekPos(int pos) {
this.pos = pos;
}
public int getSeekPos() {
return pos;
}
In your adapter below the line
holder.date.setText(" " + recordBeans.get(position).getDate());
set the progress of seekBar like this: holder.seekBar.setProgress(recordBeans.get(position).getSeekPos());
and inside the onProgressChanged add the following line recordBeans.get(position).setSeekPos(i);
This will resolve your issue.
Please let me know if it's working or not.
Thanks
