Relative layout disappears both views when setting right and left properties on both

I have the below layout right now in my RelativeLayout

<EditText
    android:id="@+id/text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true"
    android:layout_toStartOf="@+id/button"
    android:layout_toLeftOf="@id/button"
    android:hint="Whatsup!"
    android:padding="10dp" />

    <ImageView
        android:id="@id/button"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_alignParentRight="true"
        android:layout_alignBottom="@id/text"
        android:layout_alignTop="@id/text"
        android:src="@drawable/ic_mic_black_off"
        android:layout_alignParentEnd="true" />

This makes my ImageView to be of size 80dp, and the left side of it is filled with EditText.

Now if I add a property "android:layout_toRightOf="@id/text"", then both my views disappear? Why's that?

This is because of circular dependency. Your views are depending on each other to place themselves on the screen.

Your EditText is already dependent on ImageView by android:layout_toStartOf="@+id/button" Now when you add android:layout_toRightOf="@id/text" your ImageView depends on EditText it becomes circular. which is not allowed.

If you look in the studio Just below "Design" tab there will be red exclamation. click on that & you'll see following error.

Circular dependency
