java - ProgressDialog appears too late -

following code:

    public void onclick(view view) {       dialog=new progressdialog(view.getcontext());     dialog.setcancelable(true);     dialog.setmessage("initializing please wait");     dialog.settitle("loading");      dialog.setprogressstyle(progressdialog.style_spinner);     dialog.setprogress(0);     dialog.setmax(100);     dialog.show();     progressstatus=0;     new thread(new runnable() {              @override             public void run() {                 // todo auto-generated method stub                 while(progressstatus<10)                 {                     progressstatus=performtask();                   }                 /*dismiss progress bar*/                 myhandler.post(new runnable() {                      @override                     public void run() {                         // todo auto-generated method stub                         dialog.dismiss();//dismiss dialog                         toast.maketext(getbasecontext(),msg,toast.length_short).show();                        progressstatus=0;                         myprogress=0;                      }                 });              }             /* task*/             private int performtask()             {                 try {                     //---simulate doing work---                     thread.sleep(1000);                     } catch (interruptedexception e)                     {                     e.printstacktrace();                     }                     return ++myprogress;                 }         }).start(); }
