Creating abstract Activity classes

Question

I am working on creating abstract activity classes for my application that I will reuse for each activity.

1. Super Class: android.app.Activity

2. My Abstract Class extends android.app.Activity myActivity

3. Example activty in my application extends myActivity.

I will have 10-20 of these exampleActivity.

How can I write my abstract class (#2) to force my example class to override methods in android.app.Activity like onCreate() and onStart()?

Is this possible in Java?

Answer 1

Not really.

However you can create abstract functions myOnCreate and myOnStart and call those in your abstract class implementation of onCreate and onStart.

You might also want to make onCreate/onStart final, although it's difficult to see what the benefit is of forcing myOnCreate instead of onCreate.
