The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX.

Constant Value: 1 (0x00000001) ## Public constructors ### DividerItemDecoration added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` DividerItemDecoration (Context context, int orientation) ``` Creates a divider[RecyclerView.ItemDecoration](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ItemDecoration)that can be used with a[LinearLayoutManager](https://developer.android.com/reference/android/support/v7/widget/LinearLayoutManager).
| Parameters || |---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `context` | `Context`: Current context, it will be used to access resources.
| | `orientation` | `int`: Divider orientation. Should be[HORIZONTAL](https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration#HORIZONTAL)or[VERTICAL](https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration#VERTICAL).
| ## Public methods ### getItemOffsets added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void getItemOffsets (Rect outRect, View view, RecyclerView parent, RecyclerView.State state) ``` Retrieve any offsets for the given item. Each field of`outRect`specifies the number of pixels that the item view should be inset by, similar to padding or margin. The default implementation sets the bounds of outRect to 0 and returns. If this ItemDecoration does not affect the positioning of item views, it should set all four fields of`outRect`(left, top, right, bottom) to zero before returning. If you need to access Adapter for additional data, you can call[getChildAdapterPosition(View)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView#getChildAdapterPosition(android.view.View))to get the adapter position of the View.
| Parameters || |-----------|-----------------------------------------------------------------------| | `outRect` | `Rect`: Rect to receive the output.
| | `view` | `View`: The child view to decorate
| | `parent` | `RecyclerView`: RecyclerView this ItemDecoration is decorating
| | `state` | `RecyclerView.State`: The current state of RecyclerView.
| ### onDraw added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void onDraw (Canvas c, RecyclerView parent, RecyclerView.State state) ``` Draw any appropriate decorations into the Canvas supplied to the RecyclerView. Any content drawn by this method will be drawn before the item views are drawn, and will thus appear underneath the views.
| Parameters || |----------|-------------------------------------------------------------------------| | `c` | `Canvas`: Canvas to draw into
| | `parent` | `RecyclerView`: RecyclerView this ItemDecoration is drawing into
| | `state` | `RecyclerView.State`: The current state of RecyclerView
| ### setDrawable added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setDrawable (Drawable drawable) ``` Sets the[Drawable](https://developer.android.com/reference/android/graphics/drawable/Drawable.html)for this divider.
| Parameters || |------------|---------------------------------------------------------------| | `drawable` | `Drawable`: Drawable that should be used as a divider.
| ### setOrientation added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setOrientation (int orientation) ``` Sets the orientation for this divider. This should be called if[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)changes orientation.
| Parameters || |---------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `orientation` | `int`:[HORIZONTAL](https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration#HORIZONTAL)or[VERTICAL](https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration#VERTICAL)
