Add the edit data function in recycler view using interfaces

My code is working fine, it adds the data when refresh the page and it deletes the data on long press, but when I refresh the page duplicates the same data that was added before secondly I want to add the edit function in edit data button but I have no idea how to do this. Geeks help me to sort this issue.

Question 1:
The documentation is kinda unclear, but I guess using setRefreshing(false) is not enough.
Notify the widget that refresh state has changed. Do not call this when refresh is triggered by a swipe gesture.
#param refreshing Whether or not the view should show refresh progress.
So try adding setEnabled(false).
Question 2:
Use the method set(int index, String element) of ArrayList<String>.
If you want to ask your user for a new string to insert there, you could use an AlertDialog (popup) and pass an EditText to setView. When the user clicks the OK-button, you can obtain the text using EditText#getText().toString().
Use recyclerAdapter.notifyDataSetChanged() to refresh.

Slide image with recyclerview in full screen android

I have created a wallpaper app where I'm loading images from the firebase database in recyclerview. When I click on recyclerview item(image) that item's image URL is sent to the next activity and then that URL is loaded into imageView using glide.
I want to change this to something like Image-Slider. By clicking on the recyclerView item I want to show that image in full screen and 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

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);
CustomIntent.customType(itemView.getContext(), "fadein-to-fadeout");
}
});
} else {
premiumImage.setVisibility(View.GONE);
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);
CustomIntent.customType(itemView.getContext(), "fadein-to-fadeout");
}
});
}
}

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);

Few Days ago, I had been looking for similar requirement for showing slid-able image View.
This situation can be solved using ViewPager in Android.
You can use following Tutorials for building such Slide Image View using ViewPager

How to show the time when an item in a recyclerview was created?

I want to make this:
I have a RecyclerView, wherein for each item I create I want to show the time when the item was created. I want to display the time within this item.
My code:
public class VerIncidencia extends AppCompatActivity {
private FirebaseRecyclerAdapter mAdapter;
private DatabaseReference mDatabase;
String idIncidencia;
String idEmpresa;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ver_incidencia);
String uid = FirebaseAuth.getInstance().getUid();
idIncidencia = getIntent().getStringExtra("INCIDENCIA_KEY");
idEmpresa = getIntent().getStringExtra("EMPRESA_KEY");
mDatabase = FirebaseDatabase.getInstance().getReference().child("incidencia").child(uid);
RecyclerView recyclerView = findViewById(R.id.list_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
Query postsQuery = mDatabase;
FirebaseRecyclerOptions options = new FirebaseRecyclerOptions.Builder<Incidencia>()
.setQuery(postsQuery, Incidencia.class)
.setLifecycleOwner(this)
.build();
mAdapter = new FirebaseRecyclerAdapter<Incidencia, IncidenciaViewHolder>(options) {
#Override
protected void onBindViewHolder(#NonNull IncidenciaViewHolder holder, final int position, #NonNull final Incidencia empresa) {
holder.departamento.setText(empresa.departamento);
holder.prioridad.setText(empresa.prioridad);
holder.motivo.setText(empresa.motivo);
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(VerIncidencia.this, VerIncidenciaCompleta.class);
intent.putExtra("INCIDENCIA_KEY", getRef(position).getKey());
startActivity(intent);
}
});
}
#Override
public IncidenciaViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_incidencia, parent, false);
return new IncidenciaViewHolder(view);
}
};
recyclerView.setAdapter(mAdapter);
}
}
ViewHolder:
public class IncidenciaViewHolder extends RecyclerView.ViewHolder{
TextView departamento;
TextView prioridad;
TextView motivo;
public IncidenciaViewHolder(View itemView) {
super(itemView);
departamento = itemView.findViewById(R.id.departamento);
prioridad = itemView.findViewById(R.id.prioridad);
motivo = itemView.findViewById(R.id.motivo);

{
showEnterAnimation();
}
mClose_fb.setOnClickListener(new View.OnClickListener() {
#Override

}
});
}
public void showEnterAnimation()
{
Transition transition = TransitionInflater.from(this).inflateTransition(R.transition.fabtransition);
getWindow().setSharedElementEnterTransition(transition);
transition.addListener(new Transition.TransitionListener() {

});
}
public void animationRevealClose()
{
