[android] Implementing SearchView in action bar


For Searchview use these code

  1. For XML

    <android.support.v7.widget.SearchView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/searchView">
    
    </android.support.v7.widget.SearchView>
    

  2. In your Fragment or Activity

    package com.example.user.salaryin;
    
    import android.app.ProgressDialog;
    import android.os.Bundle;
    import android.support.v4.app.Fragment;
    import android.support.v4.view.MenuItemCompat;
    import android.support.v7.widget.GridLayoutManager;
    import android.support.v7.widget.LinearLayoutManager;
    import android.support.v7.widget.RecyclerView;
    import android.support.v7.widget.SearchView;
    import android.view.LayoutInflater;
    import android.view.Menu;
    import android.view.MenuInflater;
    import android.view.MenuItem;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.Toast;
    import com.example.user.salaryin.Adapter.BusinessModuleAdapter;
    import com.example.user.salaryin.Network.ApiClient;
    import com.example.user.salaryin.POJO.ProductDetailPojo;
    import com.example.user.salaryin.Service.ServiceAPI;
    import java.util.ArrayList;
    import java.util.List;
    import retrofit2.Call;
    import retrofit2.Callback;
    import retrofit2.Response;
    
    
    public class OneFragment extends Fragment implements SearchView.OnQueryTextListener {
    
    RecyclerView recyclerView;
    RecyclerView.LayoutManager layoutManager;
    ArrayList<ProductDetailPojo> arrayList;
    BusinessModuleAdapter adapter;
    private ProgressDialog pDialog;
    GridLayoutManager gridLayoutManager;
    SearchView searchView;
    
    public OneFragment() {
        // Required empty public constructor
    }
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
    
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    
        View rootView = inflater.inflate(R.layout.one_fragment,container,false);
    
        pDialog = new ProgressDialog(getActivity());
        pDialog.setMessage("Please wait...");
    
    
        searchView=(SearchView)rootView.findViewById(R.id.searchView);
        searchView.setQueryHint("Search BY Brand");
        searchView.setOnQueryTextListener(this);
    
        recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
        layoutManager = new LinearLayoutManager(this.getActivity());
        recyclerView.setLayoutManager(layoutManager);
        gridLayoutManager = new GridLayoutManager(this.getActivity().getApplicationContext(), 2);
        recyclerView.setLayoutManager(gridLayoutManager);
        recyclerView.setHasFixedSize(true);
        getImageData();
    
    
        // Inflate the layout for this fragment
        //return inflater.inflate(R.layout.one_fragment, container, false);
        return rootView;
    }
    
    
    private void getImageData() {
        pDialog.show();
        ServiceAPI service = ApiClient.getRetrofit().create(ServiceAPI.class);
        Call<List<ProductDetailPojo>> call = service.getBusinessImage();
    
        call.enqueue(new Callback<List<ProductDetailPojo>>() {
            @Override
            public void onResponse(Call<List<ProductDetailPojo>> call, Response<List<ProductDetailPojo>> response) {
                if (response.isSuccessful()) {
                    arrayList = (ArrayList<ProductDetailPojo>) response.body();
                    adapter = new BusinessModuleAdapter(arrayList, getActivity());
                    recyclerView.setAdapter(adapter);
                    pDialog.dismiss();
                } else if (response.code() == 401) {
                    pDialog.dismiss();
                    Toast.makeText(getActivity(), "Data is not found", Toast.LENGTH_SHORT).show();
                }
    
            }
    
            @Override
            public void onFailure(Call<List<ProductDetailPojo>> call, Throwable t) {
                Toast.makeText(getActivity(), t.getMessage(), Toast.LENGTH_SHORT).show();
                pDialog.dismiss();
    
            }
        });
    }
    
       /* @Override
        public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        getActivity().getMenuInflater().inflate(R.menu.menu_search, menu);
        MenuItem menuItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);
        searchView.setQueryHint("Search Product");
        searchView.setOnQueryTextListener(this);
    }*/
    
    @Override
    public boolean onQueryTextSubmit(String query) {
        return false;
    }
    
    @Override
    public boolean onQueryTextChange(String newText) {
        newText = newText.toLowerCase();
        ArrayList<ProductDetailPojo> newList = new ArrayList<>();
        for (ProductDetailPojo productDetailPojo : arrayList) {
            String name = productDetailPojo.getDetails().toLowerCase();
    
            if (name.contains(newText) )
                newList.add(productDetailPojo);
            }
        adapter.setFilter(newList);
        return true;
       }
    }
    
  3. In adapter class

     public void setFilter(List<ProductDetailPojo> newList){
        arrayList=new ArrayList<>();
        arrayList.addAll(newList);
        notifyDataSetChanged();
    }
