I have a couple of widgets that I would like to appear on each
Activity within my application. I've been trying to set up an
AbstractHandler that extends Activity that implements these common
bits of code, and then have each of my Activity classes extend that,
and then have those classes implement just the components that are
important to them. That's pretty basic stuff.
My problem is that when I set up the layout in XML in the concrete
class, it over writes the layout in the abstract class, and I then
lose the common widgets.
A general sketch of the problem.
public abstract class Foo extends Activity{
public void onCreate(Bundle bundle){
super.onCreate(bundle);
// I want these buttons inherited by every Activity in my
application.
setContentView(R.layout.abstractbuttons);
}
}
public class Bar extends Foo{
public void onCreate(Bundle bundle){
super.onCreate(bundle);
// These buttons are specific to this Activity, but by setting
the content view differently, I lose the
// Buttons in Foo.
setContentView(R.layout.specificbuttons);
}
}
So I guess what I want is a way to merge to XML layouts.
Is that possible?
Many thanks,
-J
