ListView의 각 행에 Spinner를 삽입하는 방법

Question

Fragment의 onCreateView에 Spinner을 삽입하려면 어떻게해야합니까?

ViewGroup rootView = (ViewGroup)inflater.inflate(R.layout.fragment_list2, container, false); 

는 Spinner에 대한 잘못된 레이아웃으로 발생합니다하지만 PlanetAdapter에서 개체에 대한 올바른 레이아웃입니다 :
은 내가 Spinner에서 작성하는 경우.
이 방법으로 스피너를 Listview 아래에 놓고 Spinner를 Listview의 행 뷰로 만들 수 있습니다.
Spinner은 single_listview_item이라는 또 다른 레이아웃입니다.
아래에서 내가 지금까지 시도 것을 볼 수 있습니다

Answer 1

. 그런 다음 일반적으로 Fragment에 fragment_list2.xml을 부풀려 ListView (findViewById)을 찾고 Adapter을 인스턴스화하고 ListView (setAdapter)으로 설정합니다. Adapter은 single_listview_item.xml (따라서 Spinner)을로드하고 자체를 Adapter으로 설정해야합니다. Fragment 내부의 회 전자를 찾지 않아야합니다.로드 된 후에는 각 행마다 하나씩 여러 인스턴스를 가질 수 있기 때문입니다.

그래서, 당신의 Fragment의 onCreateView : 당신의 MyListAdapter의 getView 방법 다음

ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_list2, container, false); 
ListView listView = (ListView) rootView.findViewById(R.id.listview); 
ListAdapter listAdapter = new MyListAdapter(); 
listView.setAdapter(listAdapter); 

그리고, :

Spinner spinner = (Spinner) convertView.findViewById(R.id.spinner); 
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
          getContext(), 
          R.array.country_arrays, 
          android.R.layout.simple_spinner_item); 
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
spinner.setAdapter(adapter); 

는 기본적으로 다른 하나의 내부 Adapter의 인스턴스를, 그래서 다른 클래스 (MyListAdapter)를 만들어야합니다.
