如何在適配器類中創建接口

Question

我在適配器類中創建接口，但它給了我錯誤的接口，期望在這裏。如何在適配器類中實現接口。我做了適配器和主類，但顯示錯誤的接口預計在這裏。

public class Dashboard_Adapter extends ArrayAdapter<Dashboard_Model_File> implements RecyclerSwipeAdapter<Dashboard_Adapter.SimpleViewHolder> { 
    ArrayList<Dashboard_Model_File> dashboard_model_files_obj; 

    LayoutInflater vi; 
    int Resource; 
    ViewHolder holder; 

    public Dashboard_Adapter(Context context, int resource, ArrayList<Dashboard_Model_File> objects) { 
     super(context, resource, objects); 
     vi = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     Resource = resource; 
     dashboard_model_files_obj = objects; 
    } 

    Typeface font1 = Typeface.createFromAsset(getContext().getAssets(), "fonts/cabin.regular.ttf"); 

    public static class SimpleViewHolder extends RecyclerView.ViewHolder { 
     SwipeLayout swipeLayout;

你都賺不到的接口，你想實現一個。並根據錯誤，似乎這個接口不存在。
