android - How to create relativelayouts with java code? -

i need learn creating relativelayouts java code instead of xml code.

for example, nice understand how build xml java code:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent" >  <button         android:id="@+id/btnbutton1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="button 1"/> <button         android:id="@+id/btnbutton2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="button 2"         android:layout_torightof="@+id/btnbutton1"/>       <button         android:id="@+id/btnbutton3"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="button 3"         android:layout_below="@+id/btnbutton1"/> </relativelayout>
