recyclerview에서 여러보기를 갖는 방법

Question

RecyclerView에서 여러보기를 원합니다. "pauze"라는 단어가 전달되면 "card_view_row_pauze"를 사용하고 "pauze"라는 단어가 전달되지 않으면 "card_view_row"를 사용하고 싶습니다. 몇 가지 시도 (코드에 추가 한 주석 참조)하지만 작동하지 않았습니다. 나는 stackoverflow에 대한 답변을 찾았지만, 불행히도 그것을 구현할 수없는 것 같습니다. 그렇게하려면 어떻게해야합니까?

MyRecyclerViewAdapter.java

    private ArrayList<DataObject> mDataset; 
    private static MyClickListener myClickListener; 
    private Activity mActivity; 

    public static class DataObjectHolder extends RecyclerView.ViewHolder implements View .OnClickListener { 
     TextView label;

     public DataObjectHolder(View itemView) { 
      super(itemView);

Answer 1

당신은 PAUZE 및 행 XMLS와 두 ViewHolder을 만들어야합니다. 그리고 ItemViewType에서 데이터 소스의 값과 해당 Inflate 특정 ViewHolder에 따라 텍스트 값을 확인하십시오.

여기에 몇 가지 코드가 있습니다.

public int getItemViewType(int position) { 
     if (products.size()==0){ 
      return 0; 
     }else if (viewFormat== Constants.listV){ 
      return Constants.listV; 
     }else if (viewFormat==Constants.gridV){ 
      return Constants.gridV; 
     } 
     return super.getItemViewType(position); 
    } 

그리고 ViewHolder :

public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
    { 
     if (viewType== Constants.gridV){ 
      View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_items,parent,false); 
      return new MovieViewHolder(view); 
     }else if (viewType==Constants.listV) 
     { 
      View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.linear_item_view,parent,false); 
      return new OtherViewHolder(view); 
     }else{ 
      return null; 
     } 
    }
