You should use LinearLayout to automatically add one TextView after another.

Assuming you can't live without RelativeLayout, you'll need to dynamically generate ids for all TextView you create in order to put one view under another. Here is example:

public class HelloWorld extends Activity
{       
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {       
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);

        RelativeLayout layout = (RelativeLayout)findViewById(R.id.layout);

        Random rnd = new Random();
        int prevTextViewId = 0;     
        for(int i = 0; i < 10; i++)
        {                       
            final TextView textView = new TextView(this);
            textView.setText("Text "+i);     
            textView.setTextColor(rnd.nextInt() | 0xff000000);            

            int curTextViewId = prevTextViewId + 1;
            textView.setId(curTextViewId);
            final RelativeLayout.LayoutParams params = 
                new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, 
                                                RelativeLayout.LayoutParams.WRAP_CONTENT);

            params.addRule(RelativeLayout.BELOW, prevTextViewId);
            textView.setLayoutParams(params);

            prevTextViewId = curTextViewId;
            layout.addView(textView, params);
        }              
    }    
}
