Intent intent = new Intent(secondActivity.this,details_page.class);
intent.putExtra("image",menuItemmmmm.getImageResource());
intent.putExtra("name",menuItemmmmm.getOilName());
intent.putExtra("details1",details.get(position));
intent.putExtra("details2",details2.get(position));
intent.putExtra("details3",details3.get(position));
intent.putExtra("details4",details4.get(position));
intent.putExtra("details5",details5.get(position));

intent.putExtra("howToUse",howToUse.get(position));
startActivity(intent);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu,menu);
MenuItem searchItem = menu.findItem(R.id.search);
SearchView searchView =(SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.getFilter().filter(newText);
return false;
}
});
return true;

RecyclerviwAdapter

Avtivity that i send data to it
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.details_of_oil);
imageView= findViewById(R.id.image_name);
Pdetails =findViewById(R.id.deltail_Text1);
Pdetails2 =findViewById(R.id.deltail_Text2);
Pdetails3 =findViewById(R.id.deltail_Text3);
Pdetails4 =findViewById(R.id.deltail_Text4);
Pdetails5 =findViewById(R.id.deltail_Text5);
Pdetails6 =findViewById(R.id.deltail_Text6);
price = findViewById(R.id.price);
toolbar =findViewById(R.id.toolBar);
setSupportActionBar(toolbar);
if (getSupportActionBar()!=null)
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Bundle extra = getIntent().getExtras();
if (extra != null){
int image = extra.getInt("image");
String name = extra.getString("name");
String detail1 = extra.getString("details1");
String detail2 = extra.getString("details2");
String detail3 = extra.getString("details3");
String detail4 = extra.getString("details4");
String detail5 = extra.getString("details5");
String detail6 = extra.getString("details6");
String TpriceT = extra.getString("howToUse");
imageView.setImageResource(image);
toolbar.setTitle(name);
Pdetails.setText(detail1);
Pdetails2.setText(detail2);
Pdetails3.setText(detail3);
Pdetails4.setText(detail4);
Pdetails5.setText(detail5);
Pdetails6.setText(detail6);
price.setText(TpriceT);
}
}
Glad you solved the issue. Below is the adapter code for 2nd solution:
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> implements Filterable {
private List<MenuItem> MenuItemsList;
private List<Integer> filteredId;
private RecyclerViewOnItemClick recyclerViewOnItemClick;
public RecyclerViewAdapter(List<MenuItem> nMenuItemsList, RecyclerViewOnItemClick NrecyclerViewOnItemClick) {
this.MenuItemsList = nMenuItemsList;
this.recyclerViewOnItemClick = NrecyclerViewOnItemClick;
filteredId = new ArrayList<>();
setDefaultIds(filteredId);
}
private void setDefaultIds(List<Integer> dataList) {
dataList.clear();
for (int i = 0; i < MenuItemsList.size(); i++) dataList.add(i);
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.menu_item, parent, false);
ViewHolder holder = new ViewHolder(view, recyclerViewOnItemClick);
return holder;
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
MenuItem menuItem = MenuItemsList.get(filteredId.get(position));
holder.image.setImageResource(menuItem.getImageResource());
holder.imageName.setText(menuItem.getOilName());
}
@Override
public int getItemCount() {
return filteredId.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

imageName = itemView.findViewById(R.id.image_name);
parentLayout = itemView.findViewById(R.id.RelativeLayout);
this.recyclerViewOnItemClick = recyclerViewOnItemClick;
itemView.setOnClickListener(this);
}
@Override
public void onClick(View view) {
recyclerViewOnItemClick.onItemClick(filteredId.get(getAdapterPosition()));
}
}
@Override
public Filter getFilter() {
return filter;
}
private Filter filter = new Filter() {
//run on background thread
@Override

List<Integer> filterList = new ArrayList<>();
if (charSequence == null || charSequence.length() == 0) {
// if search text is empty add all original list values to filterlist
setDefaultIds(filterList);
} else {
String filterPattern = charSequence.toString().toLowerCase().trim();
// Perform search on whole original list
MenuItem menuu;
for (int i = 0; i < MenuItemsList.size(); i++) {
menuu = MenuItemsList.get(i);
if (menuu.getOilName().toLowerCase().contains(filterPattern)) {

}
}
}
