  android:layout_width="fill_parent"
  android:layout_above="@+id/score_layout">
  <HorizontalScrollView android:layout_height="wrap_content" 
  android:id="@+id/scrollView1" 
  android:layout_width="fill_parent" 
  >
      <LinearLayout android:layout_width="fill_parent"

        if(score=="WD" || score=="NB")
        {
            addscoreball.setTextAppearance(this,R.style.plainText);
        }
        else{
            addscoreball.setTextAppearance(this,R.style.BoldText);
        }

        addscoreball.setText(score);
        addscoreball.setSingleLine(true);
        addscoreball.setBackgroundDrawable(getResources().getDrawable      (R.drawable.white_ball));
        addscoreball.setGravity(Gravity.CENTER_HORIZONTAL);
        addscoreball.setGravity(Gravity.CENTER_VERTICAL);
        LinearLayout.LayoutParams addscoreball_Params = 
            new LinearLayout.LayoutParams(35,35);  
        scoreballlayout.addView(addscoreball,addscoreball_Params);

You have to update your UI when new element is added

first initialize HorizonatlScrollView using the following code

HorizontalScrollView s = (HorizontalScrollView) findViewById(R.id.HorizontalScrollView01);

when a new element is added use the following line there to scroll your HorizontalScrollView

runOnUiThread(new Runnable() {

            public void run() {
                // TODO Auto-generated method stub
                s.fullScroll(HorizontalScrollView.FOCUS_RIGHT);

            }
        });

Thanks Deepak

There is a scrollTo method, see http://developer.android.com/reference/android/widget/HorizontalScrollView.html#scrollTo(int, int)
