অ্যান্ড্রয়েডে হরিজন্টাল (Horizontal) ListView তৈরি করা (RecyclerView)

RecyclerView + LinearLayoutManager.HORIZONTAL দিয়ে হরিজন্টাল তালিকা

পুরানো HorizontalListView বা ListView পরিবর্তে আধুনিক পদ্ধতিতে RecyclerView ব্যবহার করে হরিজন্টাল স্ক্রোলযোগ্য তালিকা তৈরি করা হয়। CardView দিয়ে কার্ড স্টাইল দেয়া হয়েছে।

ধাপ ১: প্রজেক্ট তৈরি করুন

Android Studio-তে নতুন প্রজেক্ট শুরু করুন।

ধাপ ২: Gradle ডিপেন্ডেন্সি

implementation 'androidx.recyclerview:recyclerview:1.2.1'
implementation 'androidx.cardview:cardview:1.0.0'

ধাপ ৩: লেআউট (activity_main.xml)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="https://schemas.android.com/apk/res/android"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="16dp"
    android:orientation="vertical">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

ধাপ ৪: আইটেম লেআউট (res/layout/movie_list.xml)

<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView 
    xmlns:android="https://schemas.android.com/apk/res/android"
    android:layout_width="250dp"
    android:layout_height="100dp"
    android:layout_margin="8dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="8dp">

        <TextView
            android:id="@+id/title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_toStartOf="@id/year"
            android:textColor="#222222"
            android:textSize="16sp"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/year"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentEnd="true"
            android:textColor="#999999" />

        <TextView
            android:id="@+id/genre"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true" />

    </RelativeLayout>
</androidx.cardview.widget.CardView>

ধাপ ৫: মডেল (MovieModel.java)

package com.example.sample;

public class MovieModel {
    private String title, genre, year;

    public MovieModel() {}
    public MovieModel(String title, String genre, String year) {
        this.title = title; this.genre = genre; this.year = year;
    }
    // Getter/Setter...
    public String getTitle() { return title; }
    public void setTitle(String title) { this.title = title; }
    public String getGenre() { return genre; }
    public void setGenre(String genre) { this.genre = genre; }
    public String getYear() { return year; }
    public void setYear(String year) { this.year = year; }
}

ধাপ ৬: অ্যাডাপ্টার (MoviesAdapter.java)

package com.example.sample;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import java.util.List;

public class MoviesAdapter extends RecyclerView.Adapter {
    private List moviesList;

    static class MyViewHolder extends RecyclerView.ViewHolder {
        TextView title, year, genre;
        MyViewHolder(View view) {
            super(view);
            title = view.findViewById(R.id.title);
            genre = view.findViewById(R.id.genre);
            year = view.findViewById(R.id.year);
        }
    }

    public MoviesAdapter(List moviesList) {
        this.moviesList = moviesList;
    }

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

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        MovieModel movie = moviesList.get(position);
        holder.title.setText(movie.getTitle());
        holder.genre.setText(movie.getGenre());
        holder.year.setText(movie.getYear());
    }

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

ধাপ ৭: MainActivity.java - সেটআপ

package com.example.sample;

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.DefaultItemAnimator;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {
    private List movieList = new ArrayList<>();
    private MoviesAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RecyclerView recyclerView = findViewById(R.id.recyclerView);
        adapter = new MoviesAdapter(movieList);

        // হরিজন্টাল লেআউট ম্যানেজার
        LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
        recyclerView.setLayoutManager(layoutManager);

        recyclerView.setItemAnimator(new DefaultItemAnimator());
        recyclerView.setAdapter(adapter);

        prepareMovieData();
    }

    private void prepareMovieData() {
        movieList.add(new MovieModel("Mad Max: Fury Road", "Action & Adventure", "2015"));
        movieList.add(new MovieModel("Inside Out", "Animation, Kids & Family", "2015"));
        movieList.add(new MovieModel("Star Wars: Episode VII", "Action", "2015"));
        movieList.add(new MovieModel("Shaun the Sheep", "Animation", "2015"));
        movieList.add(new MovieModel("The Martian", "Sci-Fi & Fantasy", "2015"));
        // আরও যোগ করুন...
        adapter.notifyDataSetChanged();
    }
}

ফলাফল

হরিজন্টাল স্ক্রোলযোগ্য কার্ড তালিকা দেখাবে, প্রতিটি কার্ডে মুভির নাম, জ্যানর, এবং বছর।
