Android : How to show loading icon on scrolling in android without using listview

I have Scroll view as a parent and four text view inside scroll view. I am adding data to these text view from my view class. say 15 times.now this will look like a scrolling list when i launch my app. my question is if i want to show loading symbol after say 10 items , how one can show this? Hare i am not using list view.Its just one XML and adding data externally through loop. any one know trick?

My code is some how like this- 1) textviews.xml

    <ScrollView>

      <TextView1/>
      <TextView2/>
      <TextView3/>
      <TextView4/>


    </ScrollView>

2) Viewclass.java

  Viewclass extends scrollview{

    for(int i=0;i<15;i++){

    View v=inflate textviews.xml;

     Textview1=(TectView)v.findviewbyid(R.id.textview1);
     Textview2=(TectView)v.findviewbyid(R.id.textview2);
     Textview3=(TectView)v.findviewbyid(R.id.textview3);
     Textview4=(TectView)v.findviewbyid(R.id.textview4);

     Textview1.setText("Hello1");
     Textview2.setText("Hello2");
     Textview3.setText("Hello3");
     Textview4.setText("Hello4");
     addView(v);
   }
 }

in above case how can i show loading icon after 7th element. Thanks a lot in advance!!
