[<get: Android.Runtime.Register("hasDisplayList", "()Z", "", ApiSince=29)>]
member this.HasDisplayList : bool

Property Value

boolean true if this RenderNode has a display list, false otherwise.

Attributes

Remarks

Returns whether the RenderNode has a display list. If this returns false, the RenderNode should be re-recorded with #beginRecording() and #endRecording().

A RenderNode without a display list may still be drawn, however it will have no impact on the rendering content until its display list is updated.

When a RenderNode is no longer drawn by anything the system may automatically invoke #discardDisplayList(). It is therefore important to ensure that #hasDisplayList() is true on a RenderNode prior to drawing it.

See #discardDisplayList()
