大家晚上好，我一直在寻找解决错误的解决方案 android studio 的日志正在使用 RecyclerView 发送以显示带有改造的 JSON“产品”列表。
我已经阅读了与此错误相关的问题，但我无法找到满足我需求的正确答案。
Android：RecyclerView：没有附加适配器；跳过布局
这是 android studio 显示的错误日志
RecyclerView：没有附加适配器；跳过布局
RecyclerView：没有附加适配器；跳过布局
表面：getSlotFromBufferLocked：未知缓冲区：0xa3d9a700
OpenGLRenderer：endAllStagingAnimators 位于 0xa2b6bb00 (RippleDrawable) 上，句柄为 0xa200a310
java.lang.IllegalStateException：应为 BEGIN_OBJECT 但在第 1 行第 2 列路径 $ 处为 BEGIN_ARRAY
对于这个项目，使用了这个类和布局文件
“产品”类
public class Producto {
@SerializedName("id")
@Expose
private int id;
@SerializedName("name")
@Expose
private String name;
@SerializedName("status")
@Expose
private String status;
@SerializedName("price")
@Expose

@Expose
private boolean onSale;

private int totalSales;
@SerializedName("purchase_note")
@Expose
private String purchaseNote;
@SerializedName("categories")
@Expose
private List<Category> categories;
@SerializedName("menu_order")
@Expose
private int menuOrder;
/**
*
* @return
* The id
*/
public int getId() {
return id;
}
/**
*
* @param id
* The id
*/
public void setId(int id) {
this.id = id;
}
/**
*
* @return
* The name
*/
public String getName() {
return name;
}
/**
*
* @param name

*/
public void setName(String name) {
this.name = name;
}
/**

public String getStatus() {
return status;
}
/**

public void setStatus(String status) {
this.status = status;
}
/**

public String getPrice() {
return price;
}
/**

public void setPrice(String price) {
this.price = price;
}
/**

*/
public String getRegularPrice() {
return regularPrice;
}
/**
*
* @param regularPrice
* The regular_price
*/
public void setRegularPrice(String regularPrice) {
this.regularPrice = regularPrice;
}
/**
*
* @return
* The salePrice
*/
public String getSalePrice() {
return salePrice;
}
/**
*
* @param salePrice
* The sale_price
*/
public void setSalePrice(String salePrice) {
this.salePrice = salePrice;
}
/**

*/
public String getPriceHtml() {
return priceHtml;
}
/**

}
/**

public boolean isOnSale() {

}
/**
*

* The on_sale
*/
public void setOnSale(boolean onSale) {
this.onSale = onSale;
}
/**
*
* @return

*/
public int getTotalSales() {
return totalSales;
}
/**
*
* @param totalSales
* The total_sales
*/
public void setTotalSales(int totalSales) {
this.totalSales = totalSales;
}
/**

*/
public String getPurchaseNote() {

}
/**

*/
public void setPurchaseNote(String purchaseNote) {
this.purchaseNote = purchaseNote;
}
/**

*/
public List<Category> getCategories() {

public void setCategories(List<Category> categories) {

return menuOrder;
}
/**
*

*/
public void setMenuOrder(int menuOrder) {
this.menuOrder = menuOrder;
}
}
“类别”类（与private List<Category> categories;属性匹配）
public class Category {
@SerializedName("id")
@Expose
private int id;
@SerializedName("name")
@Expose
private String name;
@SerializedName("slug")
@Expose
private String slug;
/**
*
* @return

*/
public int getId() {
return id;
}
/**
*
* @param id
* The id
*/
public void setId(int id) {
this.id = id;
}
/**
*
* @return
* The name
*/
public String getName() {
return name;
}
/**
*
* @param name
* The name
*/
public void setName(String name) {
this.name = name;
}
/**
*
* @return
* The slug
*/
public String getSlug() {
return slug;
}
/**
*
* @param slug
* The slug
*/
public void setSlug(String slug) {
this.slug = slug;
}
}
两者都包含在名为“JSONproducts”的此类中的数组中
public class JSONproducts {
private Producto[] products;
private Category[] categories;
public Producto[] getProducts(){
return products;
}
public Category[] getCategories(){
return categories;
}
}
然后请求接口称为“LecturaProductos”
public interface LecturaProductos {
@GET("Products")
Call<JSONproducts> ListarProductos();
}
Recycler View 的数据适配器称为“Adaptador”
public class Adaptador extends RecyclerView.Adapter<Adaptador.ViewHolder> {
private ArrayList<Producto> productos;
private ArrayList<Category> categoria;
public Adaptador(ArrayList<Producto> productos, ArrayList<Category> categoria){
this.productos = productos;
this.categoria = categoria;
}
@Override
public Adaptador.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_view, parent, false );
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(Adaptador.ViewHolder holder, int position) {
holder.nom_pro_tv.setText(productos.get(position).getName());
holder.id_pro_tv.setText(productos.get(position).getId());
holder.cat_pro.setText(categoria.get(position).getName());
}
@Override
public int getItemCount() {
return productos.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
private TextView nom_pro_tv, id_pro_tv, cat_pro;
public ViewHolder(View itemView) {
super(itemView);
nom_pro_tv = (TextView)itemView.findViewById(R.id.nom_pro_tv);
id_pro_tv = (TextView)itemView.findViewById(R.id.id_pro_tv);
cat_pro = (TextView)itemView.findViewById(R.id.cat_pro_tv);
}
}
}
以及活动类“ListaProductos”
public class ListaProductos extends AppCompatActivity {
private RecyclerView recyclerView;
private ArrayList<Producto> product;
private ArrayList<Category> category;
private Adaptador adaptador;
public static final String BASE_URL= "https://mydomain.com.mx/wp-json/wc/v1/";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lista_productos);
showView();
}
private void showView(){
recyclerView = (RecyclerView)findViewById(R.id.prod_recycler_view);
recyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
cargarJSON();
}
private void cargarJSON(){
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
final LecturaProductos producto = retrofit.create(LecturaProductos.class);
Call<JSONproducts> productoCall = producto.ListarProductos();
productoCall.enqueue(new Callback<JSONproducts>() {
@Override
public void onResponse(Call<JSONproducts> call, Response<JSONproducts> response) {
JSONproducts jsonproducts = response.body();
product = new ArrayList<>(Arrays.asList(jsonproducts.getProducts()));
category = new ArrayList<>(Arrays.asList(jsonproducts.getCategories()));
adaptador = new Adaptador(product, category);
recyclerView.setAdapter(adaptador);
}
@Override
public void onFailure(Call<JSONproducts> call, Throwable t) {
Log.d("Error", t.getMessage());
}
});
}
}
以及使用的 Layout XML 文件
RecyclerView 布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_lista_productos"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="mx.com.corpcap.elrollorepartidor.ListaProductos">
<android.support.v7.widget.RecyclerView
android:id="@+id/prod_recycler_view"
android:layout_height="match_parent"
android:layout_width="match_parent"/></LinearLayout>
产品列表的 CardView 布局
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/nom_pro_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="16sp"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"/>
<TextView
android:id="@+id/id_pro_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/cat_pro_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v7.widget.CardView>
一切都很好，并且可以毫无问题地启动应用程序，但是当尝试访问信息时，它会发送此问题开头引用的日志消息。
