Slide image with recyclerview in full screen android

问题

I have create wallpaper app where I'm loading images from firebase database in recyclerview. When I click on recyclerview item(image) that item's image url sent to next activity and then that url loaded into imageView using glide.

Now I want to change this to something like Image-Slider. By clicking on recyclerView item I want to show that image in full screen and also want to slide from left or right(next or previous).But I don't know how to do that.

Here is my code.

        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new GridLayoutManager(getContext(), 3));
        adapter = new FeaturedAdapter(list);
        recyclerView.setAdapter(adapter);

        databaseReference = FirebaseDatabase.getInstance().getReference().child("Wallpaper All");
        Query query = databaseReference.orderByChild("dark").equalTo(true);
        query.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

                list.clear();
                for (DataSnapshot dataSnapshot1 : dataSnapshot.getChildren()) {

                    FeaturedModel model = dataSnapshot1.getValue(FeaturedModel.class);
                    list.add(model);
                    
                }

                adapter.notifyDataSetChanged();

            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

                Log.e("TAG_DATABASE_ERROR", databaseError.getMessage());

            }
        });

FeaturedAdapter.java

public class FeaturedAdapter extends RecyclerView.Adapter<FeaturedAdapter.ViewHolder> {

    private List<FeaturedModel> featuredModels;

    }

    @Override

        holder.setData(featuredModels.get(position).getImageLink()
                , position,
                featuredModels.get(position).isPremium());

                    }

This can be solved by using ViewPager or ViewPager2 in Android

First create an Adapter

ImageSwiperAdapter2.java

public class ImageSwiperAdapter2 extends RecyclerView.Adapter<ImageSwiperAdapter2.ImageSwiper> {

    private List<FeaturedModel> list;
    private Context context;

    public ImageSwiperAdapter2(List<FeaturedModel> list, Context context) {
        this.list = list;
        this.context = context;
    }

    @NonNull
    @Override
    public ImageSwiper onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.slidingimages,
                parent, false);

        return new ImageSwiper(view);
    }

    @Override
    public void onBindViewHolder(@NonNull final ImageSwiper holder, int position) {

        Random rnd = new Random();
        int color = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
        holder.relativeLayout.setBackgroundColor(color);

        Glide.with(context.getApplicationContext())
                .load(list.get(position).getImageLink())
                .listener(new RequestListener<Drawable>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                        holder.relativeLayout.setBackgroundColor(Color.TRANSPARENT);
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                        holder.relativeLayout.setBackgroundColor(Color.TRANSPARENT);

                        return false;
                    }
                })
                .into(holder.imageView);


    }

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

    class ImageSwiper extends RecyclerView.ViewHolder {


        private ImageView imageView;
        

        public ImageSwiper(@NonNull View itemView) {
            super(itemView);

            imageView = itemView.findViewById(R.id.imageView);
          

        }


    }
}

In ViewActivity/SwiperActivity.java

public class SwiperActivity extends AppCompatActivity {

    private ViewPager2 viewPager;
    private List<FeaturedModel> list;
    private ImageSwiperAdapter2 adapter2;


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

        viewPager = findViewById(R.id.view_pager);
        
        final int pos = getIntent().getIntExtra("pos", 0);

        Singleton singleton = Singleton.getInstance();

        list = new ArrayList<>();
        list = singleton.getListSin();

        adapter2 = new ImageSwiperAdapter2(list, this);

        viewPager.setAdapter(adapter2);
        viewPager.setCurrentItem(pos);

        viewPager.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
                super.onPageScrolled(position, positionOffset, positionOffsetPixels);
            }

            @Override
            public void onPageSelected(int position) {
                super.onPageSelected(position);

                Toast.makeText(SwiperActivity.this, "Selected: " + position, Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onPageScrollStateChanged(int state) {
                super.onPageScrollStateChanged(state);
            }
        });

    }

}

You can pass the list and clicked item position in FeaturedAdapter.

In your FeaturedAdapter's setData method

private void setData(final String url, final int position, boolean premium) {
          Glide.with(itemView.getContext().getApplicationContext()).load(url).into(imageView);

            final Singleton a = Singleton.getInstance();
            a.setListSin(featuredModels);

            if (premium) {

                premiumImage.setVisibility(View.VISIBLE);

                itemView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        Intent setIntent = new Intent(itemView.getContext(), SwiperActivity.class);
                        
                        setIntent.putExtra("pos", position);
                        itemView.getContext().startActivity(setIntent);

Since the ViewActivity must show all the images(when slided) it must contain the adapter with the set of image urls. Instead of using an ImageView, use a RecyclerView in the ViewActivity and attach the adapter. In your code, do the following to make the recycler view horizontal and add slide functionality.

    recyclerView = view.findViewById(R.id.recycler_view);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL,false));
    SnapHelper snapHelper = new PagerSnapHelper();
    snapHelper.attachToRecyclerView(recyclerView);
