Butterknife funktioniert nicht mit der Adapterklasse

Question

Ich habe eine Basis recyclerview erstellt und meine andere Klasse erweitert die Basisklasse. Ich habe das butterknife implementiert. Jedoch, wenn die andere Klasse die Basisklasse erweitert, bekomme ich die Ansicht als null.

Unten ist mein Basisklasse

public abstract class BaseAdapter<T> 
     extends RecyclerView.Adapter<BaseAdapter.MyViewHolder> { 

    private List<T> mObjects; 
    private Context context; 

    public BaseAdapter(final List<T> objects, Context context) { 
     this.mObjects = objects; 
     this.context = context; 
    } 
    @Override 
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View itemView = LayoutInflater.from(parent.getContext()) 
       .inflate(getActivityLayout(), parent, false); 
     ButterKnife.bind(this,parent); 
     return new MyViewHolder(itemView); 
    } 
    /** 
    * Adds the specified object at the end of the array. 
    * 
    * @param object The object to add at the end of the array. 
    */ 
    public void add(final T object) { 
     mObjects.add(object); 
     notifyItemInserted(getItemCount() - 1); 
    } 

    /** 
    * Remove all elements from the list. 
    */ 
    public void clear() { 
     final int size = getItemCount(); 
     mObjects.clear(); 
     notifyItemRangeRemoved(0, size); 
    } 

    @Override 
    public int getItemCount() { 
     return mObjects.size(); 
    } 

    public T getItem(final int position) { 
     return mObjects.get(position); 
    } 

    public long getItemId(final int position) { 
     return position; 
    } 

    /** 
    * Returns the position of the specified item in the array. 
    * 
    * @param item The item to retrieve the position of. 
    * @return The position of the specified item. 
    */ 
    public int getPosition(final T item) { 
     return mObjects.indexOf(item); 
    } 

    /** 
    * Inserts the specified object at the specified index in the array. 
    * 
    * @param object The object to insert into the array. 
    * @param index The index at which the object must be inserted. 
    */ 
    public void insert(final T object, int index) { 
     mObjects.add(index, object); 
     notifyItemInserted(index); 

    } 

    /** 
    * Removes the specified object from the array. 
    * 
    * @param object The object to remove. 
    */ 
    public void remove(T object) { 
     final int position = getPosition(object); 
     mObjects.remove(object); 
     notifyItemRemoved(position); 
    } 

    /** 
    * Sorts the content of this adapter using the specified comparator. 
    * 
    * @param comparator The comparator used to sort the objects contained in this adapter. 
    */ 
    public void sort(Comparator<? super T> comparator) { 
     Collections.sort(mObjects, comparator); 
     notifyItemRangeChanged(0, getItemCount()); 
    } 
    public class MyViewHolder extends RecyclerView.ViewHolder { 

     public MyViewHolder(View view) { 
      super(view); 
     } 
    } 
    protected abstract int getActivityLayout(); 
} 

Unter meinen Subclass

public class SubRecyclerAdapter extends BaseAdapter { 

     private Context context; 
     private List<LocationList> getLocationLists; 
     @Nullable 
     @BindView(R.id.branchimage) 
     ImageView branchimage; 
     public SubRecyclerAdapter(List<LocationList> getLocationLists,Context context) { 
      super(getLocationLists,context); 
      this.context=context; 
      this.getLocationLists=getLocationLists; 
     } 

     @Override 
     protected int getActivityLayout() { 
      return R.layout.locationlist; 
     } 

     @Override 
     public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
      Picasso.with(context) .load(getLocationLists.get(position).getBranch_image()) .placeholder(R.drawable.dummy_image) 
        .error(R.drawable.dummy_image) .into(branchimage); 
//branchimage is null here 
     }

Answer 1

Wenn Sie Buttermesser in Ihrem Adapter verwenden möchten, müssen Sie dies in Ihrem Ansichtshalter und onCreateViewHolder zu tun:

//View Holder for performance optimizations of the recycler view display 
    static class AddProductsViewHolder extends RecyclerView.ViewHolder{ 

     @InjectView(R.id.product_image) 
     ImageView productImage; 
     @InjectView(R.id.product_name) 
     TextView productName; 
     @InjectView(R.id.product_brand) 
     TextView productBrand; 

     public final View mView; 

     public AddProductsViewHolder(View itemView) { 
      super(itemView); 
      mView = itemView; 
      ButterKnife.inject(this, itemView); 
     } 
    } 

@Override 
    public AddProductsViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View productView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_row_products, parent, false); 
     return new AddProductsViewHolder(productView); 
    } 

Verbrauch:

@Override 
    public void onBindViewHolder(AddProductsViewHolder holder, int position) { 

     try{ 
      AddProductInfo addProductInfo = addProductInfoList.get(position); 

      if(!addProductInfo.getProductImage().isEmpty()){ 
      holder.productName.setText(addProductInfo.getProductName()); 
      holder.productBrand.setText(addProductInfo.getProductBrand()); 


     } 
     catch (Exception e){ 

     } 
    } 

Kommentar unten, wenn Sie irgendwelche Zweifel haben.

Mit der neuesten Version von Buttermesser Sie müssen nur ersetzen @InjectView mit @Bind
Das ist mein alter Code, aber ich denke, es ist Ihr Zweck dient.
