[android] Android Horizontal RecyclerView scroll Direction

I made a Horizontal RecyclerView and it works fine(thanks to this) but the direction of scroll and data are expand from left to right; then How can I change the RecyclerView scroll direction like in the picture below?

My Code:

StaggeredGridLayoutManager staggeredGridLayoutManager =
                new StaggeredGridLayoutManager(
                        2, //The number of Columns in the grid
                        LinearLayoutManager.HORIZONTAL);

This following code is enough

RecyclerView recyclerView;
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL,true);

 recyclerView.setLayoutManager(layoutManager);

XML approach using androidx:

<androidx.recyclerview.widget.RecyclerView
        android:layout_width="match_parent"
        android:id="@+id/my_recycler_view"
        android:orientation="horizontal"
        tools:listitem="@layout/my_item"
        app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" 
        android:layout_height="wrap_content">

It's about Persian language problem, Just need to rotate your ListView, GridView, or .... and after that rotate your cell. You can do it in xml android:rotate="360".

Try this in fragment :

layoutManager = new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false);

mRecyclerView.setLayoutManager(layoutManager);

    horizontal_recycler_view.setLayoutManager(horizontalLayoutManagaer);
    horizontal_recycler_view.setAdapter(horizontalAdapter);
}}

Adaper Class

CustomAdapter.java

public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder> {

private ArrayList<Arraylist> dataSet;

public static class MyViewHolder extends RecyclerView.ViewHolder {

    TextView textViewName;

    ImageView imageViewIcon;

    public MyViewHolder(View itemView) {
        super(itemView);
        this.textViewName = (TextView) itemView.findViewById(R.id.txtView);
        //this.textViewVersion = (TextView) itemView.findViewById(R.id.textViewVersion);
        this.imageViewIcon = (ImageView) itemView.findViewById(R.id.image);
        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v)
            {
                if (getPosition()==0)
                {
                    Toast.makeText(v.getContext(), " On CLick one", Toast.LENGTH_SHORT).show();

                } if (getPosition()==1)
                {
                    Toast.makeText(v.getContext(), " On CLick Two", Toast.LENGTH_SHORT).show();

                } if (getPosition()==3)
                {
                    Toast.makeText(v.getContext(), " On CLick Fore", Toast.LENGTH_SHORT).show();

                }

            }
        });
    }
}

public CustomAdapter(ArrayList<Arraylist> data) {
    this.dataSet = data;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent,
                                       int viewType) {
    View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.card_view, parent, false);

    //view.setOnClickListener(MainActivity.myOnClickListener);

    MyViewHolder myViewHolder = new MyViewHolder(view);
    return myViewHolder;
}

@Override
public void onBindViewHolder(final MyViewHolder holder, final int listPosition) {

    TextView textViewName = holder.textViewName;
   // TextView textViewVersion = holder.textViewVersion;
    ImageView imageView = holder.imageViewIcon;

    textViewName.setText(dataSet.get(listPosition).getName());
    //textViewVersion.setText(dataSet.get(listPosition).getVersion());
    imageView.setImageResource(dataSet.get(listPosition).getImage());
}

@Override
public int getItemCount() {
    return dataSet.size();
}}

Arraylist.java

public class Arraylist{
String name;
int image;

public Arraylist(String name, int image) {
    this.name = name;
    this.image=image;
}
public String getName() {
    return name;
}
public int getImage() {
    return image;
}}

MyData.java

public class MyData {
static String[] nameArray = {"Gas", "Insurance", "Electronics", "Other Services"};
static Integer[] drawableArray = {R.drawable.gas_gas, R.drawable.insurance, R.drawable.electric, R.drawable.services};}

For changing the direction of swipe you can use

reverselayout attribute = true.

In Kotlin,

val layoutManager = LinearLayoutManager(this@MainActivity,LinearLayoutManager.HORIZONTAL,true)
recyclerview.layoutManager = layoutManager

In Java,

 LinearLayoutManager layoutManager = new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,true);
 recyclerview.setLayoutManager(layoutManager);

Actually it reverses the layout.

If it shows like below

1.2..3....10

it will change to

10.9..8....1

For creating Horizontal RecyclerView there are many ways.

4 Ways To Create Horizontal RecyclerView In Android

In Recycler Layout manager the second parameter is spanCount increase or decrease in span count will change number of elements show on your screen

    RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(this, 2, //The number of Columns in the grid
,GridLayoutManager.HORIZONTAL,false);
                recyclerView.setLayoutManager(mLayoutManager);

Try this

I have tried all above answers it's showing me same vertically recycler view, so I have tried another example.

1. Initialize the adapter

   private Adapter mAdapter;
   

2. set the adapter like this

   mAdapter = new Adapter();
   LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
   recycler_view.setLayoutManager(linearLayoutManager);
   recycler_view.setAdapter(mAdapter);
   

Hope this will also work for you For Complete code please refer this link

//in fragment page: 

 recyclerView.setLayoutManager(new LinearLayoutManager(this.getActivity(), HORIZONTAL,true));

//this worked for me but before that please import :

implementation 'com.android.support:recyclerview-v7:28.0.0'

You can do it with just xml.

the app:reverseLayout="true" do the job!

<android.support.v7.widget.RecyclerView
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:divider="@null"
                        android:orientation="horizontal"
                        app:reverseLayout="true"
                        app:layoutManager="android.support.v7.widget.LinearLayoutManager" />

Just add two lines of code to make orientation of recyclerview as horizontal. So add these lines when Initializing Recyclerview.

  LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);

my_recycler.setLayoutManager(linearLayoutManager);
