Android: change the class extends activities

Question

I have a MainActivity class that extends FragmentActivity and a SecondActivity that extends Fragment. Now I want to do a class BaseActivity and my classes extend it. How I can do? thanks.

public class MainActivity extends FragmentActivity implements LocationListener, OnClickListener{

    ...

    // THIS LINE USE FRAGMENTACTIVITY ONLY
    mapa = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapaMain)).getMap();

   ...

}

public class SecondActFragment extends Fragment implements OnClickListener, LocationListener { 

      ...
}

Java does not support multiple inheritance, therefore you cannot extend from Activity and Fragment in your base class. See [this post](http://stackoverflow.com/a/21824485/905349). — Tadej, Mar 17 '14 at 09:32

Why do you need a BaseActivity? create a class BaseFragmentActivity and extend FragmentActivity, override the things you need to override there and then you extend your MainActivity as BaseFragmentActivity instead

that's just a Fragment? Edit your post so it's easier to understand your intentions with this – Pontus Backlund Mar 17 '14 at 09:53
Yes and Fragments is a view, not an Activity, you use Activitys to host your fragments (FragmentActivity) – Pontus Backlund Mar 17 '14 at 10:38

I think you need two base classes - BaseActivity (or BaseFragmentActivity) and BaseFragment.
