Question

下面列表ArrayList的方法就是我現在使用的代碼：

public void onDataChange(DataSnapshot dataSnapshot) { 

      for (DataSnapshot moviecatlog: dataSnapshot.getChildren()) { 
       Actors = (String) moviecatlog.child("Actors").getValue(); 
       Description = (String) moviecatlog.child("Description").getValue(); 
       Director = (String) moviecatlog.child("Director").getValue(); 
       Genre = (String) moviecatlog.child("Genre").getValue(); 
       Published = (String) moviecatlog.child("Published").getValue(); 
       MovieUrl = (String) moviecatlog.child("MovieUrl").getValue(); 
       Status = (String) moviecatlog.child("Status").getValue(); 
       ThumbUrl = (String) moviecatlog.child("ThumbUrl").getValue(); 
       Title = (String) moviecatlog.child("Title").getValue(); 
       id = (String) moviecatlog.child("id").getValue(); 


//     recyclerView.setAdapter(new RecyclerViewAdapter(moviecatlog)); 

       ar = new ArrayList<String>(); 

       ar.add(Actors); 
       ar.add(Description); 
       ar.add(Director); 
       ar.add(Genre); 
       ar.add(MovieUrl); 
       ar.add(Published); 
       ar.add(Status); 
       ar.add(ThumbUrl); 
       ar.add(Title); 
       ar.add(id); 

       recyclerView.setAdapter(new RecyclerViewAdapter(ar)); 

如何把這些數據用在一個ArrayList？現在，我只能一次放入所有數據，但最後它只顯示ArrayList中最後一項的屬性。

Arraylist actor=new Arraylist(); 
     notification = new ArrayList<HashMap<String, String>>(); 
     notification1 = new ArrayList<HashMap<String, String>>(); 

     HashMap<String, String> list = new HashMap<String, String>; 
      actoredata[]={om puri ,raj,}; 
      directore[]={mahesh bhatt,payrelal}; 
      for(i=0;i<actoredatalenth(),i++){ 


      list.put("actor", actore[i]))); 
     notification.add(list); 
      } 
      actore.add(notification); 
      for(i=0;i<directorelenth(),i++){ 


      list.put("actor", directore[i]))); 
     notification.add(list); 
      }actore.add(notification);
