Public class Activity1 extends Activity implements Onclicklistener{
Button b1,b2;
ProgressBar PB;  
@Override
Public void OnClick (View v) {
//To monitor the button, by ID to match
if (V.getid () ==r.id.button1) {
//Getporgress () Gets the length of the initial progress bar, multiplied by 2, increments one time, and then sets the progress bar by Setprogress ()
pb.setprogress ((int) (pb.getprogress ()));
        }
else{
pb.setprogress ((int) (pb.getprogress () *0.6));
        }       
    }

@Override
protected void OnCreate (Bundle savedinstancestate) {
Super.oncreate (savedinstancestate);
Setcontentview (R.LAYOUT.ACT1);
b1= (Button) Findviewbyid (R.id.button1);
B2= (Button) Findviewbyid (R.id.button2);
