如何从SupportMapFragment获取片段扩展中的主Activity

Question

我有： 的 MainActivity

fragment = new ListReportsFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content, fragment).commit();

使用这个简单的代码，我调用从SupportMapFragment

扩展的framgment

MyFragment

public class MyFragment extends SupportMapFragment {
  public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        MainActivity main = (MainActivity) getParentFragment().getActivity()
    }
}

但main的值始终为null。我如何发送或获取MainActivity？

Answer 1

更改

MainActivity main = (MainActivity) getParentFragment().getActivity();

带

MainActivity main = (MainActivity) getActivity();
