Circular dependencies cannot exist in RelativeLayout

The problem is caused when there is a circular reference in the layout parameters.

For example, you have a button A layout_below to button B, now you can not give any alignment references of button A to button B like button B align_right to button A.

Following code in your layout caused the circular dependencies,

<TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:text="Weight"
            android:id="@+id/weig"
            android:layout_marginEnd="40dp"
            android:layout_above="@+id/weightn"
            android:layout_alignParentEnd="true"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="46"
            android:id="@+id/weightn"
            android:layout_below="@+id/weig"
            android:layout_alignEnd="@+id/weig"
            android:layout_marginRight="7dp"
            android:textColor="#ffffff" />

Cause:

First Text View(weig) : android:layout_above="@+id/weightn"

Second Text View(weightn) : android:layout_below="@+id/weig"
