我正在尝试使用 Retrofit 从 URL 获取书籍 xml 数据。但是当应用程序运行时,它显示错误。我是新来的所以请帮助我。这是错误信息:

    02-20 23:06:37.943 23835-23835/com.santossingh.reader E/error:
org.simpleframework.xml.core.ValueRequiredException: Unable to satisfy @org.simpleframework.xml.ElementList(data=false, empty=true, entry=, inline=true, name=work, required=true, type=void) on field 'works' public java.util.List com.santossingh.reader.AWS.GoodReadsModels.Results.works for class com.santossingh.reader.AWS.GoodReadsModels.Results at line 2

这是 XML 文件结构以及我的模型和类:

1- URL XML 文件的结构:

<?xml version="1.0" encoding="UTF-8"?>
<GoodreadsResponse>
<Request>
<authentication>true</authentication>
<key><![CDATA[xxxxx]]></key>
<method><![CDATA[search_index]]></method>

</work>
<results>

Here is the clarity of structure <imagelink> of structure XML file for more clarity.

2- Results.class 模型:

@Root (name = "results", strict = false)
public class Results {

@ElementList (name = "work", inline = true)
public List<Work> works;

public Results() {
}

public Results(List<Work> works) {
this.works = works;
}

public List<Work> getWorks() {
return works;
}

public void setWorks(List<Work> works) {
this.works = works;
}
}

2- Work.class 模型:

@Root(name = "work", strict = false)
public class Work {

@Path("best_book")
@Element(name = "id")
private int id;

@Path("best_book")
@Element (name = "title")
private String title;

@Path("best_book/author")
@Element(name = "name")
private String author;

@Path("best_book")
@Element (name = "image_url")
private String image;

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public String getAuthor() {
return author;
}

public void setAuthor(String author) {
this.author = author;
}

public String getImage() {
return image;
}

public void setImage(String image) {
this.image = image;
}
}

最佳答案

我找到了答案。在 Result.class 中,只需更改 @ElementList() 参数。这是解决方案:

错误-

    @ElementList(name = "work", inline = true)
public List<Work> works;

解决方案-

    @ElementList(inline = true, required = false)
public List<Work> works;

每当发生错误时,只需记住@ElementList() 中的两件事

1- inline=true
2- required=false
example : @ElementList(inline = true, required = false)
