In your black view remove
android:layout_above="@+id/textView5"
You'll end up with the following:
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="@android:color/black"
android:layout_below="@+id/converter"
android:layout_marginTop="20dp"
android:layout_alignParentLeft="true"
android:id="@+id/view" />
You're already anchoring the view to converter
So you don't need the extra anchor.
