@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.cart_search_menu, menu);

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setMaxWidth(Integer.MAX_VALUE);
        
        SearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                
                // your code
                
                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                // your code
                return false;
            }
        });
        return true;

Check this screenshot try this

in menu file:

<item
    android:id="@+id/actionTenantSearch"
    android:icon="@drawable/ic_search"
    android:title="@string/search"
    app:showAsAction="ifRoom|collapseActionView"
    app:actionViewClass="androidx.appcompat.widget.SearchView"
    />

In kotlin file:

  private var searchItem : MenuItem? = null
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
    inflater.inflate(R.menu.search_tenant_menu, menu)
    searchItem = menu.findItem(R.id.actionTenantSearch)

    val searchView = searchItem?.actionView as SearchView
    searchView.setOnQueryTextListener(object :
        SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(s: String): Boolean {
            CommonUtils.showToast(requireContext(), s)
            searchView.clearFocus()
            return true
        }

        override fun onQueryTextChange(s: String): Boolean {

            return true
        }
    })
    super.onCreateOptionsMenu(menu, inflater)
}

@vaibhav have you implemented filterable class to your listview or recyclerview. After that call that filterable method in on your search query. You will get appropriate reault Like this

public class Adaptername extends RecyclerView.Adapter<ContactAdapter.MyViewHolder> implements Filterable {

}

CustomFilter filter;

@Override
public Filter getFilter() {
    if (filter == null) {
        filter = new CustomFilter();
    }
    return filter;
}

class CustomFilter extends Filter {
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        // TODO Auto-generated method stub
        FilterResults results = new FilterResults();
        if (constraint != null && constraint.length() > 0) {
            //CONSTARINT TO UPPER
            constraint = constraint.toString().toUpperCase();
            ArrayList<AllInOnetItem> filters = new ArrayList<AllInOnetItem>();
            //get specific items
            for (int i = 0; i < filterList.size(); i++) {
                if (filterList.get(i).getName().toUpperCase().contains(constraint)) {
                    AllInOnetItem p = new AllInOnetItem(filterList.get(i).getName(), filterList.get(i).getNumber(),filterList.get(i).getEmail());
                    filters.add(p);
                }
            }
            results.count = filters.size();
            results.values = filters;
        } else {
            results.count = filterList.size();
            results.values = filterList;
        }
        return results;
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        // TODO Auto-generated method stub
        allInOnetItems = (ArrayList<AllInOnetItem>) results.values;
        notifyDataSetChanged();
    }
}

I changed the sequence of code lines after that it worked fine.

Before:

super.onCreate(savedInstanceState);
Toolbar toolbar = findViewById(R.id.category1_toolbar);
setSupportActionBar(toolbar);
setContentView(R.layout.activity_product_list);

After:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_list);
Toolbar toolbar = findViewById(R.id.category1_toolbar);
setSupportActionBar(toolbar);
