Public constructors

DividerItemDecoration

public DividerItemDecoration (Context context, 
                int orientation)

Creates a divider RecyclerView.ItemDecoration that can be used with a LinearLayoutManager.

Parameters
`context`	`Context`: Current context, it will be used to access resources.
`orientation`	`int`: Divider orientation. Should be `HORIZONTAL` or `VERTICAL`.

Public methods

getDrawable

public Drawable getDrawable ()

Returns
`Drawable`	the `Drawable` for this divider.

public 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 RecyclerView.getChildAdapterPosition(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.

public 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

public void setDrawable (Drawable drawable)

Sets the Drawable for this divider.

Parameters
`drawable`	`Drawable`: Drawable that should be used as a divider.

setOrientation

public void setOrientation (int orientation)

Sets the orientation for this divider. This should be called if RecyclerView.LayoutManager changes orientation.

Parameters
`orientation`	`int`: `HORIZONTAL` or `VERTICAL`
