button - Progress Bar in android -


i have tried implement progressbar in application gets displayed when click on button plays sound.

i have done coding run time exception , application not starting. here posting code reference.

holder.imgplaybtn.setonclicklistener(new view.onclicklistener()              {                  public void onclick(view v)                  {                     progressdialog progressdialog;                     onclicklistener mycontext = this;                     progressdialog = new progressdialog((context) mycontext);                     progressdialog.setprogressstyle(progressdialog.style_horizontal);                     progressdialog.setmessage("...");                     progressdialog.setcancelable(false);                  }             });

can body please me?

thanks, david,

progressdialog = new progressdialog((context) mycontext); wrong, can use instead of it: 

 progressdialog = new progressdialog(v.getcontext());

and also, forgot call show() method show progressbar dialog box, write below line @ end:

progressdialog.show();
