This post will guide you to create simple and awesome animation using RecyclerView on Its items.
RecyclerView with CardView is now becoming standard in Android where someone wants to display information in list style.
RecyclerView provides best memory optimizations by reusing list cells.
In today’s world developers are making awesome tricks and building beautiful apps, So in this post i am going to tell you how you can create some awesome and cool animation by using RecyclerView and CardView
What is in this post:
1.Creating a android application with android studio
2.Creating a MainActivity
3.Editing activity_main layout.xml
3.Creating a ItemsAdapter for RecyclerView
4.Creating a layout for Adapter’s single item.
In first step Create a project in Android studio with name CardAnimation and create MainActivity
To use recycler view and card view you need to add these libraries into app’s build.gradle file.

1 2 3 4 |
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' compile 'com.squareup.picasso:picasso:2.5.2' |
Now edit you MainActivity’s layout file and put following contents
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:background="@color/appBackground" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.codezlab.cardanimation.activites.MainActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/recycler_view" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_centerHorizontal="true" android:layout_centerVertical="true" /> </RelativeLayout> |
Now your MainActivity code will be like

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |
public class MainActivity extends AppCompatActivity { private RecyclerView mRecyclerView; private ItemsAdapter itemsAdapter; private List<String> imagesList; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); imagesList=new ArrayList<>(); imagesList.add("https://cdn.pixabay.com/photo/2016/11/26/00/18/car-1859759__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2016/11/18/12/44/wristwatch-1834241__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2015/08/13/17/24/vintage-1950s-887272__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2014/09/03/20/15/legs-434918__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2016/11/22/22/55/buildings-1851047__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2014/12/10/10/27/straw-carts-563005__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2014/07/20/10/40/bottle-397697__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2014/06/17/02/54/car-370173__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2015/04/10/00/39/snack-715534__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2016/08/30/18/45/grilled-1631727__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2013/11/21/12/25/orange-214872__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2016/02/05/15/34/pasta-1181189__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2014/08/20/23/10/raspberries-422979__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2015/02/05/05/58/peanut-624601__340.jpg"); imagesList.add("https://cdn.pixabay.com/photo/2015/04/10/00/41/food-715539__340.jpg"); mRecyclerView=(RecyclerView)findViewById(R.id.recycler_view); mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); itemsAdapter=new ItemsAdapter(this,imagesList); mRecyclerView.setAdapter(itemsAdapter) } } |
In above code i am using a List to store images url which will be loaded at runtime by image loader and image caching library Picasso, Also you need to add internet permission in manifest file so that above images can be downloaded.
Now ItemsAdapter is a custom adapter class which extends RecyclerView.Adapter.

package com.codezlab.cardanimation.adapters; import android.content.Context; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.animation.AnimationUtils; import android.widget.ImageView; import com.codezlab.cardanimation.R; import com.squareup.picasso.Picasso; import java.util.List; /** * Created by coderzlab on 10/6/17. */ public class ItemsAdapter extends RecyclerView.Adapter<ItemsAdapter.CardViewHolder>{ private List<String> list; private Context mContext; public ItemsAdapter(Context mContext,List<String> list) { this.mContext=mContext; this.list = list; } @Override public CardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { return new CardViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.card_single_item, parent, false)); } @Override public void onBindViewHolder(CardViewHolder holder, int position) { Picasso.with(mContext).load(list.get(position)).into(holder.imageIV); holder.getView().setAnimation(AnimationUtils.loadAnimation(mContext,R.anim.zoom_in)); } @Override public int getItemCount() { return list.size(); } protected class CardViewHolder extends RecyclerView.ViewHolder{ private View view; protected ImageView imageIV; public CardViewHolder(View itemView) { super(itemView); this.view=itemView; this.imageIV=(ImageView)itemView.findViewById(R.id.imageIV); } public View getView() { return view; } } } |
Inside onCreateViewHolder we need to inflate custom layout which contains CardView and and ImageView
Create a file with name card_single_item.xml
and place following contents inside file

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content"> <android.support.v7.widget.CardView android:layout_width="match_parent" android:layout_height="wrap_content"> <ImageView android:id="@+id/imageIV" android:layout_width="match_parent" android:layout_height="wrap_content" android:adjustViewBounds="true" android:scaleType="centerCrop" android:minHeight="200dip" /> </android.support.v7.widget.CardView> </LinearLayout> |

1 2 3 4 5 6 7 |
@Override public void onBindViewHolder(CardViewHolder holder, int position) { Picasso.with(mContext).load(list.get(position)).into(holder.imageIV); holder.getView().setAnimation(AnimationUtils.loadAnimation(mContext,R.anim.zoom_in)); } |
Is the main logic for animation and image loading is inside onBindViewHolder method
As you can see there is zoom_in animation file has been used to animate cardview
Now you need to create a anim directory inside app’s resources folder and create
a zoom_in.xml file
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:fillAfter="true" > <scale xmlns:android="http://schemas.android.com/apk/res/android" android:duration="500" android:fromXScale="0.7" android:fromYScale="0.7" android:pivotX="50%" android:pivotY="50%" android:toXScale="1" android:toYScale="1" > </scale> </set> |
Now you have done all the things to make card zoom in animation.

Hmm it appears like your website ate my first comment (it was extremely long) so
I guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your blog.
I too am an aspiring blog blogger but I’m still new to the whole thing.
Do you have any helpful hints for inexperienced blog writers?
I’d definitely appreciate it.
