int anchorGravity ``` A[Gravity](https://developer.android.com/reference/android/view/Gravity.html)value describing which edge of a child view's[anchor](https://developer.android.com/reference/android/support/design/widget/CoordinatorLayout.LayoutParams#getAnchorId())view the child should position itself relative to.
### dodgeInsetEdges added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int dodgeInsetEdges ``` A[Gravity](https://developer.android.com/reference/android/view/Gravity.html)value describing how this child view dodges any inset child views in the CoordinatorLayout. Any views which are inset on the same edge as this view is set to dodge will result in this view being moved so that the views do not overlap.
### gravity added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int gravity ``` A[Gravity](https://developer.android.com/reference/android/view/Gravity.html)value describing how this child view should lay out. If either or both of the axes are not specified, they are treated by CoordinatorLayout as[TOP](https://developer.android.com/reference/android/view/Gravity.html#TOP)or[START](https://developer.android.com/reference/android/support/v4/view/GravityCompat#START). If an[anchor](https://developer.android.com/reference/android/support/design/widget/CoordinatorLayout.LayoutParams#setAnchorId(int))is also specified, the gravity describes how this child view should be positioned relative to its anchored position.
### insetEdge added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int insetEdge ``` A[Gravity](https://developer.android.com/reference/android/view/Gravity.html)value describing how this child view insets the CoordinatorLayout. Other child views which are set to dodge the same inset edges will be moved appropriately so that the views do not overlap.
### keyline added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int keyline ``` The index of the horizontal keyline specified to the parent CoordinatorLayout that this child should align relative to. If an[anchor](https://developer.android.com/reference/android/support/design/widget/CoordinatorLayout.LayoutParams#setAnchorId(int))is present the keyline will be ignored.

| ## Public methods ### getAnchorId added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int getAnchorId () ``` Get the id of this view's anchor.
| Returns || |-------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `int` | A[view id](https://developer.android.com/reference/android/view/View.html#getId())or[NO_ID](https://developer.android.com/reference/android/view/View.html#NO_ID)if there is no anchor
| ### getBehavior added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` Behavior getBehavior () ``` Get the behavior governing the layout and interaction of the child view within a parent CoordinatorLayout.
| Returns || |--------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------| | [Behavior](https://developer.android.com/reference/android/support/design/widget/CoordinatorLayout.Behavior) | The current behavior or null if no behavior is specified
| ### setAnchorId added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setAnchorId (int id) ``` Set the id of this view's anchor. The view with this id must be a descendant of the CoordinatorLayout containing the child view this LayoutParams belongs to. It may not be the child view with this LayoutParams or a descendant of it.

| Parameters || |------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `id` | `int`: The[view id](https://developer.android.com/reference/android/view/View.html#getId())of the anchor or[NO_ID](https://developer.android.com/reference/android/view/View.html#NO_ID)if there is no anchor
| ### setBehavior added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setBehavior (Behavior behavior) ``` Set the behavior governing the layout and interaction of the child view within a parent CoordinatorLayout. Setting a new behavior will remove any currently associated[Behavior tag](https://developer.android.com/reference/android/support/design/widget/CoordinatorLayout.Behavior#setTag(android.view.View, java.lang.Object)).

| Parameters || |------------|------------------------------------------------------------------------| | `behavior` | `Behavior`: The behavior to set or null for no special behavior
