Where and How to call requestChildRectangleOnScreen()?

Question

Hiho, I am trying to initialize the presented child from my HorizontalScrollView but it doesn't seem to work.

How do I automatically scroll to the rightmost child of my ScrollView? Ideally inside to initialization code of the View, so that the user doesn't even see the left children first?

        san_startimg.setOnClickListener(new OnClickListener() { 
            @Override
            public void onClick(View arg0) {
//              
//              Log.v("Pos",Integer.toString(jump));
//              boolean gan_check= hv.requestChildRectangleOnScreen(navagtion_bar.getChildAt(jump), rectangle, immediate);
//              System.out.println("Gan_Check"+gan_check);
                if(gan_check == true)
                {
                    Log.v("Success","Sankar");
                    int kemp=0;
                    final Rect rectangle1=new Rect(0,0,120,120);
                    gan_check=hv.requestChildRectangleOnScreen(navagtion_bar.getChildAt(kemp), rectangle1, immediate);
                    System.out.println("Inside If"+gan_check+" "+"kemp"+kemp+"rectangle1"+rectangle1);
                }

            }
            });
             final Rect rectangle1=new Rect(15,15,15,15);
            san_endimg.setOnClickListener(new OnClickListener() { 
                @Override
                public void onClick(View arg0) {

                    Log.v("Pos",Integer.toString(jump));
                    gan_check = hv.requestChildRectangleOnScreen(navagtion_bar.getChildAt(jump), rectangle1, immediate);
                    System.out.println("Gan_Check"+gan_check);

                }
                });
