Their are mainly 8 files use in this project

1. src/MainActivity.java :-This MainActivity.java file used to add SearchView in RecyclerView and display filtered result.

2. res/layout/activity_main.xml :-activity_main.xml is the layout file(xml code of RecyclerView) of MainActivity.java.

3. res/layout/customitem.xml :-creating custom layout of image and text .

6. Src/drawable :-images store here that are used in app.

7.dependencies in build.gradle(Module:app)

Dependencies{

    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:recyclerview-v7:25.3.1'
    compile 'com.android.support:cardview-v7:25.3.1'
}

8. menu file searchfile.xml (res/menu/searchfile.xml )

Starting the code here -----

STEP 1. Create a new Project WRCSearchFilter in Android Studio.

STEP 2. Add this dependencies in build.gradle(Module:app) and then sync this library

Dependencies{
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:recyclerview-v7:25.3.1'
    compile 'com.android.support:cardview-v7:25.3.1'
}

STEP 3. save and Paste this images in res/drawable folder

download click link Images(Recyclerview with searchview filter)

Step 4.Create menu file searchfile.xml(res/menu/serachfile.xml)

Searchfile.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<item
    android:id="@+id/search"
    android:icon="@drawable/ic_search_white_24dp"
    android:orderInCategory="300"
    android:title="search here..."
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="ifRoom|collapseActionView" />

</menu>

STEP 5. Create java file Item.java

1. src/Item.java :- Generate Setter and getter here.

Item.java

package com.example.amitrawat.rcsearchfilter;

/** * Created by amit rawat on 11/27/2017. */public class Item {

private String name;

private int photo;

public Item(String name, int photo) {

this.name = name;

this.photo = photo;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getPhoto() {

return photo;

}

public void setPhoto(int photo) {

this.photo = photo;

}

STEP 6. Create xml file customitem.xml

1. res/layout/customitem.xml :- creating custom layout of image and text .

Customitem.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:cardCornerRadius="10dp"
app:cardUseCompatPadding="true">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="5dp">

    <ImageView
        android:id="@+id/product_image"
        android:layout_width="100dp"
        android:layout_height="80dp"
        android:padding="0.75dp"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/product_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:layout_toRightOf="@+id/product_image"
        android:text="title"
        android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
</android.support.v7.widget.CardView>

STEP 7. Create java file MainActivityAdapter.xml

1. src/MainActivityAdapter.java :- MainActivityAdatper.java is the adapter class of RecyclerView that is used in MainActivity.java class.

MainActivityAdapter.java

package com.example.amitrawat.rcsearchfilter;

import android.content.Context;

import android.support.v7.widget.RecyclerView;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

import android.widget.TextView;

import android.widget.Toast;

import java.util.ArrayList;

import java.util.List;

/** * Created by amit rawat on 11/27/2017. */public class MainActivityAdapter extends

RecyclerView.Adapter<MainActivityAdapter.Holderview>{

private List<Item> productlist;

private Context context;

public MainActivityAdapter(List<Item> productlist, Context context) {

this.productlist = productlist;

this.context = context;

}

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

View layout= LayoutInflater.from(parent.getContext()).

inflate(R.layout.customitem,parent,false);

return new Holderview(layout);

}

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

holder.v_name.setText(productlist.get(position).getName());

holder.v_image.setImageResource(productlist.get(position).getPhoto());

holder.itemView.setOnClickListener(new View.OnClickListener() {

@Override public void onClick(View view) {

Toast.makeText(context, "click on " + productlist.get(position).getName(),

Toast.LENGTH_LONG).show();

}

});

}

@Override public int getItemCount() {

return productlist.size();

}

public void setfilter(List<Item> listitem)

{

productlist=new ArrayList<>();

productlist.addAll(listitem);

notifyDataSetChanged();

}

class Holderview extends RecyclerView.ViewHolder

{

ImageView v_image;

TextView v_name;

Holderview(View itemview)

{

super(itemview);

v_image=(ImageView) itemview.findViewById(R.id.product_image);

v_name = (TextView) itemView.findViewById(R.id.product_title);

}

STEP 8. Write code in java file MainActivity.java and xml file activity_main.xml

1.res/layout/activity_main.xml :-activity_main.xml is the layout file(xml code of RecyclerView) of MainActivity.java.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp"
tools:context="com.example.amitrawat.rcsearchfilter.MainActivity">

<android.support.v7.widget.RecyclerView
    android:id="@+id/listshow"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fadeScrollbars="true" />

</RelativeLayout>

2 src/MainActivity.java :-This MainActivity.java file used to add SearchView in RecyclerView and display filtered result.

MainActivity.java

package com.example.amitrawat.rcsearchfilter;

import android.graphics.Color;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

import android.support.v7.widget.LinearLayoutManager;

productlists.add(new Item("Ducati Scrambler 2017 Mach 2.0",

R.drawable.scramblermach));

productlists.add(new Item("yamaha Fazer 2017 25",

R.drawable.yamahafazer));

listshowrcy = (RecyclerView) findViewById(R.id.listshow);

listshowrcy.setHasFixedSize(true);

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);

listshowrcy.setLayoutManager(linearLayoutManager);

adapter = new MainActivityAdapter(productlists, MainActivity.this);

listshowrcy.setAdapter(adapter);

}

@Override public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.searchfile, menu);

final MenuItem myActionMenuItem = menu.findItem(R.id.search);

searchView = (SearchView) myActionMenuItem.getActionView();

changeSearchViewTextColor(searchView);

((EditText) searchView.findViewById(

android.support.v7.appcompat.R.id.search_src_text)).

setHintTextColor(getResources().getColor(R.color.white));

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

@Override public boolean onQueryTextSubmit(String query) {

if (!searchView.isIconified()) {

searchView.setIconified(true);

}

myActionMenuItem.collapseActionView();

return false;

}

@Override public boolean onQueryTextChange(String newText) {

final List<Item> filtermodelist=filter(productlists,newText);

adapter.setfilter(filtermodelist);

return true;

}

});

return true;

}

private List<Item> filter(List<Item> pl,String query)

{

query=query.toLowerCase();

final List<Item> filteredModeList=new ArrayList<>();

for (Item model:pl)

{

final String text=model.getName().toLowerCase();

if (text.startsWith(query))

{

filteredModeList.add(model);

}

return filteredModeList;

}

//for changing the text color of searchview private void changeSearchViewTextColor(View view) {

if (view != null) {

if (view instanceof TextView) {

((TextView) view).setTextColor(Color.WHITE);

return;

} else if (view instanceof ViewGroup) {

ViewGroup viewGroup = (ViewGroup) view;

for (int i = 0; i < viewGroup.getChildCount(); i++) {
