Использование getFragmentManager в ListActivity

Question

Я просто хочу знать, возможно ли это с первого раза. Я создал custom listView based on the tutorial I read from Sai Geetha. Ну, он отлично работает на моем приложении, за исключением того, что ему нужно расширить ListActivity вместо FragmentActivity. Теперь мне сложно настроить и добавить диалог для этого, так как мне нужно применить диалог фрагмента, и я не могу использовать getFragmentManager(), так как я не работаю с FragmentActivity. Есть ли другой способ сделать это, не жертвуя ListActivity? Благодаря!

Вот мой код до сих пор

XML:

conversation_list_view

<?xml version="1.0" encoding="utf-8"?> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:orientation="vertical" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent"> 

    <ListView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:id="@id/android:list" 
      android:layout_marginLeft="10dp" 
      android:layout_marginRight="10dp" 
      android:layout_marginBottom="5dp" 
      android:layout_marginTop="20dp"/> 
</LinearLayout>

Answer 1

Вы можете использовать ListFragment внутри FragmentActivity вместо использования ListActivity.
