Why does my image doesn't show in imageView?

Question

so I am working with my project using android studio. I created a simple xml with CardView and used an ImageView in it. Code bellow:

<androidx.cardview.widget.CardView
                android:layout_width="120dp"
                android:layout_height="150dp"
                android:layout_centerInParent="true"
                android:layout_marginStart="5dp"
                android:layout_marginEnd="5dp"
                app:cardBackgroundColor="@color/white"
                app:cardCornerRadius="20dp"
                app:cardElevation="3dp"
                app:cardMaxElevation="20dp">


                <ImageView
                    android:id="@+id/imageView3"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    tools:srcCompat="@drawable/vector_illustration" />
            </androidx.cardview.widget.CardView>

But when I run the app, the image doesn't appear. It should be look like this, but it look like this instead. Is it because the image is too big?(i download the img from google image). How to fix this?

You can try this

xmlns:app="http://schemas.android.com/apk/res-auto"
.
...
...
<androidx.appcompat.widget.AppCompatImageView
   android:id="@+id/imageView3"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   app:srcCompat="@drawable/vector_illustration"
/>
