Question

我是android编程的初学者，我无法理解为什么我的项目中的HomeAdapter类的onBindViewHolder实现有错误。

***This my HomeAdapter.***

这是我的课程，我想用我的recyclerview和cardview。

public class HomeAdapter extends RecyclerView.Adapter<HomeAdapter.MyViewHolder> {
   private Context mContext;
    private List<Products> productsList;


        public class MyViewHolder extends RecyclerView.ViewHolder {
            public TextView title,count;
            public ImageView thumbnail,overflow;

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

                title=(TextView)itemView.findViewById(R.id.list_item);
                count=(TextView)itemView.findViewById(R.id.list_count);
                thumbnail=(ImageView) itemView.findViewById(R.id.thumbnail);
                overflow=(ImageView) itemView.findViewById(R.id.overflow);
            }
        }
        public  HomeAdapter(Context mContext,List<Products> productsList){
            this.mContext=mContext;
            this.productsList=productsList;
        }
        @Override
        public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View itemView= LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_view,parent,false);

            return new MyViewHolder(itemView);
        }

        @Override
        public void onBindViewHolder(final MyViewHolder holder, int position) {
            Products products=productsList.get(position);
            holder.title.setText(products.getName());
            holder.count.setText(products.getNumOfProducts());

            Glide.with(mContext).load(products.getThumbnail()).into(holder.thumbnail);

            holder.overflow.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    showPopUpMenu(holder.overflow);
                }
            });

        }

我的custom_view。 强调文字

 <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:layout_margin="5dp"
            android:id="@+id/card_view"
            android:elevation="3dp"
            card_view:cardCornerRadius="0dp">
            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent">
                <ImageView
                    android:id="@+id/thumbnail"
                    android:layout_width="match_parent"
                    android:layout_height="160dp"
                    android:background="?attr/selectableItemBackgroundBorderless"
                    android:clickable="true"
                    android:scaleType="fitXY"/>
                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:id="@+id/list_item"
                    android:layout_below="@+id/thumbnail"
                    android:paddingLeft="10dp"
                    android:paddingTop="10dp"
                    android:paddingRight="10dp"
                    android:textSize="15dp"
                    android:textColor="#8E00aa"/>
                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_below="@+id/list_item"
                    android:id="@+id/list_count"
                    android:textSize="12dp"
                    android:paddingLeft="10dp"
                    android:paddingBottom="5dp"
                    android:paddingRight="10dp"
                    />
                <ImageView
                    android:layout_width="20dp"
                    android:layout_height="30dp"
                    android:id="@+id/overflow"
                    android:layout_alignParentRight="true"
                    android:layout_below="@+id/thumbnail"
                    android:layout_marginTop="10dp"
                    android:scaleType="centerCrop"
                    android:src="@drawable/navbar"/>
            </RelativeLayout>
        </android.support.v7.widget.CardView>

    </LinearLayout>

这是onBindViewHolder上的错误

请关注这个问题

Answer 1

将此holder.count.setText(String.valueOf(products.getNumOfProducts()));更改为products.getNumOfProducts()。我猜int返回@echo off cd %~pd0 for /f "delims=" %%i in ('svnversion') do set VERSION=%%i @echo %VERSION%值，而android正在寻找该int值的资源值，但无法找到它。所以你应该给出字符串值。
