如何設置適配器以顯示ListFragment

Question

如何設置Adapter以顯示ListFragment ，我嘗試設置此底部的代碼不起作用

ListFragment僅顯示一個值（index = 0），而其他index不顯示

ChatGroupMembersFragment.java

public class ChatGroupMembersFragment extends ListFragment {


    ArrayList<ChatApiFriendListGroupModel> chatApiFriendListGroupModelArrayList = new ArrayList<>();
    ArrayList<ChatApiFriendListGroupModel> chatApiFriendListGroupModels = new ArrayList<>();
    private AdapChatGroupMembers adapChatGroupMembers;
    public static ArrayList<ChatApiFriendListGroupModel> f =new ArrayList<>();

    public static ChatGroupMembersFragment newInstance(ChatApiFriendListGroupModel member) {


        f.add(member);



        return new ChatGroupMembersFragment();
    }



    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        Log.d("ChatGroupMembersFragmen","onViewCreated");
        ShareData.tx_home_titlebar.setText(getActivity().getResources().getString(R.string.tx_group_member));


        Member();
    }

    private void Member() {



        for (ChatApiFriendListGroupModel chatApiFriend: f){


            chatApiFriendListGroupModelArrayList.add(chatApiFriend);

        }



        adapChatGroupMembers = new AdapChatGroupMembers(getActivity(), chatApiFriendListGroupModelArrayList);
        setListAdapter(adapChatGroupMembers);
        adapChatGroupMembers.notifyDataSetChanged();
    }


}

和myadapter

 public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHoder = new ViewHolder();
        LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if (convertView==null){
            convertView =  layoutInflater.inflate(R.layout.fragment_chat_group_members,parent ,false);
            viewHoder.tx_name_member = (TextView) convertView.findViewById(R.id.tx_name_member);
            viewHoder.img_profile_member =(ImageView) convertView.findViewById(R.id.img_profile_member);

            viewHoder.tx_name_member.setTypeface(MainActivity.typeface_normal);
            convertView.setTag(viewHoder);
        }else {
            viewHoder = (ViewHolder) convertView.getTag();
        }

        viewHoder.tx_name_member.setText(chatApiFriendListGroupModelArrayList.get(position).getMembers().get(position).getFirstname());

        return convertView;
    }

並且它在列表視圖中僅顯示一個（ get(0).getFirstName(); ）

和My Data在FirstName中有6個值（ get(0-6).getFirstName() ）

如何獲取所有值以顯示ListFragment ？

Answer 1

您的ArrayList似乎只有一個元素，您可以在此處添加：

f.add(member);

因此，以下調用僅在位置為0時返回元素：

chatApiFriendListGroupModelArrayList.get(position);

如果我正確理解並且getMembers()返回了正確的數據集，則可能需要執行以下操作：

viewHoder.tx_name_member.setText(chatApiFriendListGroupModelArrayList.get(0)
   .getMembers().get(position).getFirstname());

並相應地重寫getCount() ：

@Override
public int getCount() {
    return chatApiFriendListGroupModelArrayList.get(0)
        .getMembers().size();
}
