Question

我想要保存JsonObject项目以改进 DataModel ，但在运行应用程序时，我会在LogCat my dataModels 中显示错误：

public class R_CatModel {

    @SerializedName("id")
    public Integer id;

}

CatCategory dataModel：

public class R_CatCategory {

    public String getCatTitle() {

    public void setCatTitle(String catTitle) {
        this.catTitle = catTitle;
    }

    @SerializedName("title")

我的POJO课程：

public class R_CatModelResponse {

    public String Cat_status;
    @SerializedName("count")
    public int Cat_count;
    @SerializedName("pages")
    public int Cat_pages;
    @SerializedName("category")
    public Retrofit_ColoniesModel category;
    @SerializedName("posts")
    public List<R_CatModel> Cat_posts;

    public String getCat_status() {
        return Cat_status;
    }

    public void setCat_status(String cat_status) {
        Cat_status = cat_status;
    }

    public int getCat_count() {
        return Cat_count;
    }

    public void setCat_count(int cat_count) {
        Cat_count = cat_count;
    }

    public int getCat_pages() {
        return Cat_pages;
    }

    public void setCat_pages(int cat_pages) {
        Cat_pages = cat_pages;
    }

    public Retrofit_ColoniesModel getCategory() {
        return category;
    }

    public void setCategory(Retrofit_ColoniesModel category) {
        this.category = category;
    }

    public List<R_CatModel> getCat_posts() {
        return Cat_posts;
    }

    public void setCat_posts(List<R_CatModel> cat_posts) {
        Cat_posts = cat_posts;
    }
}

我的适配器代码：

@Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {

        ((DataViewHolder) holder).main_category.setText(Html.fromHtml(mDateSet.get(position).getCategories().getCatTitle()));

但是在运行应用程序时，请显示 logCat ：

Error : com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 3901 path $.posts[0].categories

如何解决此问题并在我的适配器中加载 jsonObject ？谢谢所有＆lt; 3

Answer 1

您期望categories有一个类别。

@SerializedName("categories")
public R_CatCategory categories;

当你得到一个清单时。

"categories": [{
    "id": 1,
    "slug": "%d8%b3%d8%b1%da%af%d8%b1%d9%85%db%8c",
    "title": "\u0633\u0631\u06af\u0631\u0645\u06cc",
    "description": "\u062a\u0648\u06cc \u0627\u06cc\u0646 \u06a9\u0644\u0648\u0646\u06cc \u0647\u0645\u0647 \u0686\u06cc\u0632 \u0648\u0627\u0633\u0647 \u0633\u0631\u06af\u0631\u0645 \u0628\u0648\u062f\u0646 \u0647\u0633\u062a. \u067e\u0633 \u0628\u062f\u0648 \u0628\u0631\u0648 \u062a\u0648\u0634",
    "parent": 0,
    "post_count": 29
}],

因此，定义一个能够处理JSON数组的类型。

@SerializedName("categories")
public List<R_CatCategory> categories;
