이미지보기 XML에 한 줄을 추가 할 수 있습니다.

<ImageView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:src="@mipmap/ic_launcher" 
     android:id="@+id/mainlogo" 
     android:contentDescription="main logo" 
     tools:layout_constraintBottom_creator="1" 
     app:layout_constraintBottom_toTopOf="@+id/imageView2" 
     tools:layout_constraintLeft_creator="1" 
     app:layout_constraintLeft_toLeftOf="@+id/imageView2" 
     android:layout_above="@+id/imageView2" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" 
     android:layout_marginLeft="84dp" 
     android:layout_marginStart="84dp" 
     android:layout_marginBottom="113dp" /> 

    <ImageView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:src="@mipmap/ic_launcher" 
     android:id="@+id/imageView2" 
     tools:layout_constraintRight_creator="1" 
     tools:layout_constraintBottom_creator="1" 
     app:layout_constraintBottom_toBottomOf="parent" 
     app:layout_constraintRight_toRightOf="parent" 
     android:layout_marginBottom="85dp" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" />
