Hi I want to add Floating Action Button on a Fragment Class, but when ever I add implements AppCompatActivity I get this error: 

"getLoaderManager()' in 'android.support.v4.app.Fragment' 
clashes with 'getLoaderManager()' in 'android.app.Activity'; attempting to use incompatible return type"

public class home extends Fragment implements AppCompatActivity{

```
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.home, container, false);
    return rootView;

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });

}

```

}
