It:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:weightSum="1">

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_alignTop="@id/imageView3"

<ImageView

</RelativeLayout>

Error: (78, 35) A resource was not found that matches the specified name (in 'layout_toLeftOf' with the value '@ id / imageView3').
