    To implement view Animation in Android follow the steps mentioned below:-

    1) Start a new project in android studio.

    2) Now create a new Android resource Directory under res directory then choose interpolater option in directory type and name it anim .

    3) Here is your MainActivity code

    MainActivity.java

    public class MainActivity extends Activity {
        private Button mFade,mBlink,mMove,mSlide,mClockwise;
        private ImageView mImage;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            mImage=(ImageView)findViewById(R.id.image123);
            mFade=(Button)findViewById(R.id.Fade);
            mClockwise=(Button)findViewById(R.id.Clockwise);
            mSlide=(Button)findViewById(R.id.Slide);
    
            mFade.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
            //implementing fade  animation with the help of fade.xml file 
                    mImage.startAnimation(android.view.animation.AnimationUtils.loadAnimation(MainActivity.this, R.anim.fade));
                }
            });
            mClockwise.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                        //implementing rotation animation with the help of rotate.xml file
                    mImage.startAnimation(android.view.animation.AnimationUtils.loadAnimation(MainActivity.this,R.anim.rotate));
                }
            });
            mSlide.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                        //implementing slide animation with the help of slide.xml file
                    mImage.startAnimation(android.view.animation.AnimationUtils.loadAnimation(MainActivity.this,R.anim.slide));
                }
            });
    
        }
    }
    

    4) Create new animation resource files fade.xml, rotate.xml and slide.xml in anim directory. fade.xml

    <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_interpolator">
        <alpha
            android:fromAlpha="0"
            android:toAlpha="1"
            android:duration="2000" >
        </alpha>
    
        <alpha
            android:startOffset="2000"
            android:fromAlpha="1"
            android:toAlpha="0"
            android:duration="2000" >
        </alpha>
    </set>
    

    rotate.xml

    <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
        <rotate xmlns:android="http://schemas.android.com/apk/res/android"
            android:fromDegrees="0"
            android:toDegrees="360"
            android:pivotX="50%"
            android:pivotY="50%"
            android:duration="5000" >
        </rotate>
    
        <rotate xmlns:android="http://schemas.android.com/apk/res/android"
            android:startOffset="5000"
            android:fromDegrees="360"
            android:toDegrees="0"
            android:pivotX="50%"
            android:pivotY="50%"
            android:duration="5000" >
        </rotate>
    
    </set>
    

    slide.xml

    <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android"
        android:fillAfter="true">
        <scale
            android:duration="500"
            android:fromXScale="1.0"
            android:fromYScale="1.0"
            android:interpolator="@android:anim/linear_interpolator"
            android:toXScale="2.0"
            android:toYScale="2.0" />
    </set>
    

    5) Here is your activity_main.xml code

    activity_main.xml

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
        android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:paddingBottom="@dimen/activity_vertical_margin"
        tools:context=".MainActivity"
        android:orientation="vertical">
    
    
        <ImageView
            android:id="@+id/image123"
            android:layout_width="200dp"
            android:layout_height="200dp"
            android:src="@android:drawable/btn_star_big_on"
            android:layout_gravity="center"
        />
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:layout_marginLeft="20dp"
            android:layout_marginTop="20dp">
           <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="clockwise"
                android:id="@+id/Clockwise"
                android:onClick="zoom"/>
    
            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="fade"
                android:id="@+id/Fade"
                android:onClick="fade"/>
    
            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="slide"
                android:onClick="slide"
                android:id="@+id/Slide"
                />
        </LinearLayout>
    
    </LinearLayout>
