Android: Access activity from handler

I have the following handler:

public class SiteListener implements OnItemClickListener{
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
    }
}

I want to be able to call the following:

myActivity.getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.site_info, siteInfoFragment)
            .commit();

How do I gain access to the activity from SiteListener? Is there a way using the adapterView?

You can cast FragmentActivity with view to get the instance of FragmentActivity.

FragmentActivity activity = ((FragmentActivity)view.getContext());
activity.getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.site_info, siteInfoFragment)
            .commit();

Pass a reference to the activity to the SiteListener when you create it.

EDIT Add code example:

public class SiteListener implements OnItemClickListener{
    private MyActivity myActivity;

    public SiteListener(MyActivity myActivity) {
        this.myActivity = myActivity;
    }

    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
        myActivity.getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.site_info, siteInfoFragment)
            .commit();

    }
}
