android - Image of item changes when scroll up and down listview -

i have used custom base adapter listview. each row contains progressbar, imagebutton , 2 textview. have made audio player each row play button (which changes image pause on clicking) , progressbar (which starts showing progress button clicks). problem arise when scroll list:

1) when scroll down , back, image of imagebutton returns play , progressbar clears progress although song still playing.

2) other items of listview starts showing pause images on imagebutton , progressbar shows progress of song being played(i think after every 6th row 7th 1 that). please me. here custom adapter:

public class audioadapter extends baseadapter {  context context; uri[] uris; layoutinflater layout; imagebutton previousbutton = null; progressbar previousprogressbar = null; static private handler myhandler = new handler();  public audioadapter(context context, int resource, uri[] uris) {     // todo auto-generated constructor stub      this.context = context;     this.uris = uris; }  class audioviewholder {     imagebutton play;     textview date, duration;     progressbar progressbar;      public audioviewholder(view v) { // todo auto-generated constructor         // stub         play = (imagebutton) v.findviewbyid(r.id.imagebutton_rowaudioplay);         date = (textview) v.findviewbyid(r.id.textview_rowaudiodate);         duration = (textview) v                 .findviewbyid(r.id.textview_rowaudioduration);         progressbar = (progressbar) v                 .findviewbyid(r.id.progressbar_rowaudioplay);      } }  @override public int getcount() { // todo auto-generated method stub     return uris.length; }  @override public view getview(int position, view convertview, viewgroup parent) {      view row = convertview;     final audioviewholder holder;     if (row == null) {          layout = (layoutinflater) context                 .getsystemservice(context.layout_inflater_service);         row = layout.inflate(r.layout.row_hometab_audio, parent, false);         row.setvisibility(view.invisible);         holder = new audioviewholder(row);         row.settag(holder);     } else {         holder = (audioviewholder) row.gettag();     }     holder.duration.settext(audioplayer.getaudiominutes(context,             uris[position])             + ":"             + audioplayer.getaudioseconds(context, uris[position]));     debugmessage.logmessage("inside audioadapter getview() . isrownull = "             + (row == null));     holder.progressbar.settag(position);     holder.play.settag(position);     holder.play.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated method stub             int row_position = (integer) v.gettag();             if (holder.play == previousbutton && audioplayer.isplaying)                 audioplayer.pauseaudio(holder);             else {                 if (holder.play == previousbutton                         && audioplayer.isplaying == false) {                     audioplayer.resumeaudio(holder);                     audioplayer.progressbarupdate(holder, myhandler);                 } else if (audioplayer.isplaying) {                     audioplayer.stopaudio(previousbutton,                             previousprogressbar);                     audioplayer.playaudio(context, uris[row_position],                             holder);                     audioplayer.progressbarupdate(holder, myhandler);                     holder.play                             .setimageresource(android.r.drawable.ic_media_pause);                     previousbutton = holder.play;                     previousprogressbar = holder.progressbar;                     audioplayer.isplaying = true;                 } else {                     audioplayer.playaudio(context, uris[row_position],                             holder);                     audioplayer.progressbarupdate(holder, myhandler);                     holder.play                             .setimageresource(android.r.drawable.ic_media_pause);                     previousbutton = holder.play;                     previousprogressbar = holder.progressbar;                     audioplayer.isplaying = true;                 }             }             audioplayer.onaudiofinished(holder);         }     });      row.setvisibility(view.visible);     return row; }  @override public object getitem(int position) {     // todo auto-generated method stub     return null; }   @override public long getitemid(int position) {     // todo auto-generated method stub     return 0; } 

here player:

anyone have idea?

the logic within click event, changes views assign images , visibility...that needs happen every getview() call.

so lets playing song x. if view scrolls off screen, , comes on screen...it'll fire off getview(). getview() call needs able restore view state of playing song.

so ideally, every getview() need way say, "hey, have uri. please tell me if it's playing , how many seconds along it." update views accordingly.
