zoom in animation imageview

i'm trying to scale an imageview using following code which works fine

<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="6000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1.2"
        android:toYScale="1.2"
        >
    </scale>
</set>
 <ImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:scaleType="fitXY"
        tools:src="@drawable/image"
        app:layout_constraintDimensionRatio="H,16:9"
        app:layout_constraintTop_toTopOf="parent"/>

But it also scales the height and width of the imageview as well. Is there a way to scale an image of imageview without making the view bigger?

This will not work because the ImageView itself is scaled. So, no matter what the scaleType or adjustViewBounds is, the ImageView still gets scaled. The image can't be scaled separately from the view, instead you can animate the padding of the ImageView

My suggestion would be to add the ImageView in another view, for example a RelativeLayout, set the RelativeLayout to the size you want and then scale the ImageView.

Doing this, the RelativeLayout will remain the same size and can be used to do what your where intended to do, while the ImageView is scaled.

You can make your image auto resize to fit the imageView like this 

<ImageView
   android:id="@id/img_id"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:adjustViewBounds="true"
   android:scaleType="fitCenter"/>

adjustViewBounds is the key to re-scale your image to fill the imageView
