In the below example I have created vector drawable function. For this first I have created vectordrawable.xml, animvectordrawable.xml , anim/rotation.xml and path_morph.xml layout. In activity_main.xml layout I have added TextView and ImageView. And now In MainActivity I have used OnClickListener(). You can see the below example it will clearly describe you how to make vector drawable in android .

Step(1)-Create vectordrawable.xml layout

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:height="64dp"
    android:width="64dp"
    android:viewportHeight="600"
    android:viewportWidth="600">
    <group
        android:name="rotationGroup"
        android:pivotX="300.0"
        android:pivotY="300.0"
        android:rotation="45.0" >
        <path
            android:name="v"
            android:fillColor="#000000"
            android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
    </group>
</vector>

Step(2)-animvectordrawable.xml layout

<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/vectordrawable" >
    <target
        android:name="rotationGroup"
        android:animation="@anim/rotation" />
    <target
        android:name="v"
        android:animation="@anim/path_morph" />
</animated-vector>

Step(3)-Create rotation.xml in anim folder

<objectAnimator
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="6000"
    android:propertyName="rotation"
    android:valueFrom="0"
    android:valueTo="360" />

Step(4)-Create path_morph.xml in anim folder

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
        android:duration="3000"
        android:propertyName="pathData"
        android:valueFrom="M300,70 l 0,-70 70,70 0,0   -70,70z"
        android:valueTo="M300,70 l 0,-70 70,0  0,140 -70,0 z"
        android:valueType="pathType" />
</set>

Step(5)-Create activity_main.xml layout-

<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:orientation="vertical"
    android:padding="10dp"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:autoLink="web"
        android:text="http://android-er.blogspot.com/"
        android:textStyle="bold" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/imageview1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/animvectordrawable"
            android:background="#D0D0D0"/>
        <ImageView
            android:id="@+id/imageview2"
            android:layout_width="32dp"
            android:layout_height="32dp"
            android:src="@drawable/animvectordrawable"
            android:background="#B0B0B0"/>
        <ImageView
            android:id="@+id/imageview3"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/animvectordrawable"
            android:background="#909090"/>
    </LinearLayout>

</LinearLayout>

Step(6)-MainActivity-

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ImageView imageView1 = (ImageView)findViewById(R.id.imageview1);
        imageView1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Drawable drawable = ((ImageView) v).getDrawable();
                ((Animatable) drawable).start();
            }
        });

        ImageView imageView2 = (ImageView)findViewById(R.id.imageview2);
        imageView2.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                Drawable drawable = ((ImageView)v).getDrawable();
                ((Animatable) drawable).start();
            }
        });

        ImageView imageView3 = (ImageView)findViewById(R.id.imageview3);
        imageView3.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                Drawable drawable = ((ImageView)v).getDrawable();
                ((Animatable) drawable).start();
            }
        });
    }

}
