Display Class

Definition

Remarks

Provides information about the size and density of a logical display.

The display area is described in two different ways. <ul> <li>The application display area specifies the part of the display that may contain an application window, excluding the system decorations. The application display area may be smaller than the real display area because the system subtracts the space needed for decor elements such as the status bar. Use WindowMetrics#getBounds() to query the application window bounds.</li> <li>The real display area specifies the part of the display that is accessible to an application in the current system state. The real display area may be smaller than the physical size of the display in a few scenarios. Use WindowManager#getCurrentWindowMetrics() to identify the current size of the activity window. UI-related work, such as choosing UI layouts, should rely upon WindowMetrics#getBounds(). See #getRealSize / #getRealMetrics for details.</li> </ul>

A logical display does not necessarily represent a particular physical display device such as the internal display or an external display. The contents of a logical display may be presented on one or more physical displays according to the devices that are currently attached and whether mirroring has been enabled.

Obsolete.

Display flag: Indicates that the display has a secure video output and supports compositing secure surfaces.

FlagSupportsProtectedBuffers
Obsolete.

Display flag: Indicates that the display supports compositing content that is stored in protected graphics buffers.

InvalidDisplay

Invalid display id.
