Unless I'm misunderstanding something, couldn't you just provide a public
method on your LinearLayout subclass that will do the desired work for you?
As an example, I wrote a subclass to RelativeLayout for one of my apps that
contained a Gallery widget, some text views, and some image views. In order
to change things at runtime I provided some convenience methods on my
RelativeLayout class that provided the necessary behavior for me...
Here is some sample code that would illustrate how to provide access to a
text view and change its text:
public class TestRelLayout extends RelativeLayout
{
...
public void setTitleText(String text)
{
m_titleTextView.setText(text);
}
...
}
