列出你的布局。xml:

public class MainActivity extends AppCompatActivity {

ProductAdapter。java类：

public ProductAdapter(Context context, List<Product> productList) {
    this.context = context;
    this.productList = productList;
}

@Override
public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.list_layout, null);


    ProductViewHolder productViewHolder = new ProductViewHolder(view);

    return new ProductViewHolder(view);
}

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

    Product product = productList.get(position);
    holder.textView_Title.setText(product.getTitle());
    holder.textView_Desc.setText(product.getDesc());

    holder.imageView.setImageDrawable(context.getResources().getDrawable(product.getImage()));
}

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

class ProductViewHolder extends RecyclerView.ViewHolder {


    ImageView imageView;
    TextView textView_Title;
    TextView textView_Desc;


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

        imageView = itemView.findViewById(R.id.imageView);
        textView_Title = itemView.findViewById(R.id.textView_Name);
        textView_Desc = itemView.findViewById(R.id.textView_Desc);
    }
}

}

改变这个

<android.support.v7.app.AlertController.RecycleListView
        android:id="@+id/recyclerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:dividerHeight="5dp">
    </android.support.v7.app.AlertController.RecycleListView>

到

<android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
          />

警报控制器。RecycleListView和RecycleView都不同。
