Accessing Android Views in Java files

Question

I've designed a RelativeLayout with children elements such as TextView and ImageView. What I want to do is to create a RelativeLayout object from my created RelativeLayout in XML, that way I can access to its children elements and modify them (change image from ImageView and change the text from TextView). How can I do this? It would be kind of like this.

RelativeLayout lay = new "myrelativelayout";
ImageView img = lay.children[0];
TextView txt = lay.children[1];

Thanks!

XML:

<RelativeLayout
    android:id="@+id/relative_layout_id"
         ...>
    <TextView
        android:id="@+id/textview_id"
        .../>
</RelativeLayout>

Activity onCreate:

RelativeLayout lay = (RelativeLayout) findViewById(R.id.relative_layout_id);

To change children use:

TextView child = (TextView) findViewById(R.id.textview_id);
child.setText(text);

or:

View child = lay.getChildAt(i);
