Answer 1

You've to provide the location of your newly added view. As @Adinia said, with no position, it will be aligned to the top by default. So you can use the following code to do it with RelativeLayout;

RelativeLayout containerLayout = (RelativeLayout) findViewById(R.id.container);

for (int i = 0; i < 20; i++) {

    TextView dynaText = new TextView(this);

    dynaText.setText("Some text " + i);
    dynaText.setTextSize(30);

    // Set the location of your textView.
    dynaText.setPadding(0, (i * 30), 0, 0);

    containerLayout.addView(dynaText);
}

If you want to show multiple textviews one after the other, then you should go with LinearLayout.

You may also add Dynamic textview to relative layout. Here with i have attached some code this may help you.

    RelativeLayout ll=(RelativeLayout) findViewById(R.id.rl);
    for(int i = 0; i < 20; i++) 
    {
       TextView cb = new TextView(this);
       cb.setText("YORUMLAR"+yorum[0]+i);
       cb.setTextSize(30);
       cb.setId(2000+i);
       RelativeLayout.LayoutParams TextViewLayoutParams = new RelativeLayout.LayoutParams(100,100);
       if (i != 0 )DispViewLayoutParams.addRule(RelativeLayout.BELOW, 2000 - (i-1));
       ll.addView(cb,TextViewLayoutParams); 
    }

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);
        }              
    }    
}
