button below other button programmatically android

Question

i have in xml tis code:

<RelativeLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/mainLayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

    <Button
        android:id="@+id/examp1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/examp2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/examp1" />
</RelativeLayout>

I want to create these buttons programmatically and i use:

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

for (int i=0; i<1; i++)
{
     Button new_button = new Button(this);
     new_button.setText("blabla");
     new_button.setId(i);
     new_button.setLayoutParams(new LayoutParams(
                        ViewGroup.LayoutParams.WRAP_CONTENT,         
                        ViewGroup.LayoutParams.WRAP_CONTENT));

     mainLayout.addView(new_button);
}

How can I translate this command android:layout_below="@id/examp1" programmatically?

Use RelativeLayout.LayoutParams. Use addRule(), for your example use it with RelativeLayout.BELOW and the id (R.id.examp1)

So, i have to put each button on seperate layout, then use the addRule and then add each button to the layout? – Nikitas Jun 10 '11 at 12:52
What do you want to do? If you want to layout buttons one below another then use a LinearLayout with vertical orientation. If you still want to do this with a RelativeLayout you need to do it with the addRule() method over the same RelativeLayout, no need to put each button on a separate layout. – aromero Jun 10 '11 at 12:58
