adding views dynamically

I am using the following layout and want to add textviews one below another dynamically(depending on the data I want to display)

main.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:id="@+id/contain"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >




    </LinearLayout>


</ScrollView>

So I tried this

public class Feeds extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent intent=getIntent();
        Bundle b=intent.getExtras();
      String s= b.getString("datapack");

      Log.w("String",s);
      String data[]=s.split("#");




String temp="";
      LinearLayout l=(LinearLayout)findViewById(R.id.contain);
      LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
              (LayoutParams.WRAP_CONTENT), (LayoutParams.WRAP_CONTENT));

      RelativeLayout relative = new RelativeLayout(getApplicationContext());
      relative.setLayoutParams(lp);


      for(int i=1;i<data.length;i++)
      {Log.w("i data",data[i]);
          temp=temp  + data[i] + ",";
          Log.w("tag",temp);
          if(i%5==0)
          {Log.w("data",temp);
              TextView tv = new TextView(getApplicationContext());
              tv.setLayoutParams(lp);
              tv.setId(i);
              tv.setText(temp);
              relative.addView(tv, lp);
              temp=null;

          }

      }
      l.addView(relative);




    }
}

I am using Scrollview for the first time so that is crating a bit of problem but the main problem is that the textviews in the relative layout overlap one another.How can I specify the gap between each view??

I don't see where you are defining the positions for each textview, ie layout_below, layout_toLeftOf... If no positions are defined the relative layout stacks each view in the upper left corner.

Addition

It seems digulino and I agree. I would like to add that you should be able to get the layout scheme you want with only a RelativeLayout inside a ScrollView, maybe a HorizontalScrollView too if you want horizontal scrolling with fling gesture support.

If you're adding views into a RelativeLayout you have to set where the view will be placed, different than LinearLayout that you only need to add the views inside there.

Trye to change to this

LinearLayout layout= new LinearLayout (getApplicationContext());
  layout.setLayoutParams(lp);

And here you go a little tip. Do not do this

if(i%5==0)
{Log.w("data",temp);

try to do this

if(i%5==0){
   Log.w("data",temp);

it's better to read and understand
