Question

我希望在Google Play商店等垂直回收视图中创建水平回收视图，并通过排列和显示获取数据，我看到此示例http://android-pratap.blogspot.co.uk/2015/12/horizontal-recyclerview-in-vertical.html 但是不要在recyclerview中使用volley显示数据，如何使用此API在recyclelerview horizontallerview中的recyclerview horizontal recyclerview中使用volley 显示数据？ API：http://monaasoft.com/indianfm/api/test.json 请帮帮我

数据

public class Data {


private String title;
private List<Section> section;


public Data(){

}

public Data(String title,List<Section> sections){
    this.title=title;
    this.section=section;
}


public String getTitle() {
    return title;
}

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

public List<Section> getSection() {
    return section;
}

public void setSection(List<Section> section) {
    this.section = section;
}


 }

科

public class Section {
private String name;
private String image;


public Section(){

}


public Section(String name,String image){
    this.name=name;
    this.image=image;
}

public String getImage() {
    return image;
}

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

public String getName() {
    return name;
}

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


 }
