在垂直recyclerview創建水平recyclerview像谷歌播放商店與凌空

我想創建水平recyclerview內像垂直recyclerview像谷歌播放存儲和獲取數據與齊射和顯示，我看到這個示例http://android-pratap.blogspot.co.uk/2015/12/horizontal-recyclerview-in-vertical.html 但不使用volley顯示數據在recyclerview ，如何使用這個API來顯示數據在回收站水平回收站內垂直回收站查看排球？ API：http://monaasoft.com/indianfm/api/test.json 請幫助我在垂直recyclerview創建水平recyclerview像谷歌播放商店與凌空

數據

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; 
} 


}
