How can I reuse the Activity code?

Question

We can use <include /> to include a layout into another.

I'm including activity_main.xml into activity_second.xml using <include />.

activity_main.xml has a <TextView /> and a <Button />. And the <Button /> has a handler doThis(View v){..} in MainActivity.java

How do I reuse the Button Handler in the SecondActivity.java

Answer 1

You can use Fragments for that
