Develop a Multiple Horizontal Scroll with Vertical Scroll Within Single Screen Like Google Play Store

Hi guys after long time I comeback with a new post I hope it will be helpful for beginners and experienced android developers. Generally Android Developers got app requirement to develop multiple horizontal scroll view in single screen with vertical scroll like Google Play Store. Now a days it becomes trend to develop video streaming songs and movies apps like Netflix so, it's become popular view now. Now i'm going to explain how to develop view like Google Play Store. Also I will share the complete code in this app. In this blog I created a local JSON file in assets folder which stores all data in JSON formate latter which I parse in file MainActivity.java so, that developer no need worry to how to display parsed data through network call. If you want to display data from string array in string.xml then there is a blog (Create a Vertical Scroll and Horizontal Scroll App like Google Play Store) is already exist. I also follow this blog to create this blog. First create an android project in android studio. After create project add two dependencies of RecyclerView and CardView in build.gradle file which will be implemented later in the project.

build.gradle

compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'
compile 'com.android.support:cardview-v7:26.0.0-alpha1'

After adding dependencies never forgot to sync your project to avoid error. After that create two folder for model and adapter class within package. Create two model class in model folder SectionDataModel.java and SingleItemModel and generate Getter and Setter method.

SingleItemModel.java

package com.kit.googleplaystoresample.model;

import java.io.Serializable;

public class SingleItemModel implements Serializable {
    public String getSubcategory_id() {
        return subcategory_id;
    }

    public void setSubcategory_id(String subcategory_id) {
        this.subcategory_id = subcategory_id;
    }

    public String getSubcategory_name() {
        return subcategory_name;
    }

    public void setSubcategory_name(String subcategory_name) {
        this.subcategory_name = subcategory_name;
    }

    public SingleItemModel(String subcategory_id, String subcategory_name) {
        this.subcategory_id = subcategory_id;
        this.subcategory_name = subcategory_name;
    }

    private String subcategory_id, subcategory_name;

    public SingleItemModel() {

    }


}

SectionDataModel.java

package com.kit.googleplaystoresample.model;

import java.io.Serializable;
import java.util.ArrayList;

public class SectionDataModel implements Serializable {
    private String headerTitle;
    private ArrayList allItemInSection;

    public SectionDataModel() {
    }

    public SectionDataModel(String headerTitle, ArrayList allItemInSection) {
        this.headerTitle = headerTitle;
        this.allItemInSection = allItemInSection;
    }

    public String getHeaderTitle() {
        return headerTitle;
    }

    public void setHeaderTitle(String headerTitle) {
        this.headerTitle = headerTitle;
    }

    public ArrayList getAllItemInSection() {
        return allItemInSection;
    }

    public void setAllItemInSection(ArrayList allItemInSection) {
        this.allItemInSection = allItemInSection;
    }
}

After that create two adapter RecyclerViewDataAdapter.java and SectionListDataAdapter.java in adapter folder.

    }

    @Override

        ItemRowHolder rowHolder = new ItemRowHolder(v);
        snapHelper = new GravitySnapHelper(Gravity.START);
        return rowHolder;
    }

    @Override

        final String sectionName = dataList.get(position).getHeaderTitle();
     final    ArrayList singleSectionItems = dataList.get(position).getAllItemInSection();
        holder.itemTitle.setText(sectionName);
        SectionListDataAdapter adapter = new SectionListDataAdapter(singleSectionItems, mContext);
        holder.recyclerView.setHasFixedSize(true);
        holder.recyclerView.setLayoutManager(new LinearLayoutManager(mContext, LinearLayoutManager.HORIZONTAL, false));
        holder.recyclerView.setAdapter(adapter);
        holder.recyclerView.setRecycledViewPool(recycledViewPool);
        snapHelper.attachToRecyclerView(holder.recyclerView);
        holder.btnMore.setOnClickListener(new View.OnClickListener() {

               mContext.startActivity(intent);
            }
        });
    }

    @Override
