Window

extends Object
java.lang.Object
   ↳ android.view.Window

Class Overview

Abstract base class for a top-level window look and behavior policy. An instance of this class should be used as the top-level view added to the window manager. It provides standard UI policies such as a background, title area, default key processing, etc.

The only existing implementation of this abstract class is android.policy.PhoneWindow, which you should instantiate when needing a Window. Eventually that class will be refactored and a factory method added for creating Window instances without knowing about a particular implementation.

Constants

protected static final int DEFAULT_FEATURES

Added in API level 1

This constant was deprecated in API level 22.
use getDefaultFeatures(android.content.Context) instead.

The default features enabled.

Constant Value: 65 (0x00000041)

public static final int FEATURE_ACTION_BAR

Added in API level 11

Flag for enabling the Action Bar. This is enabled by default for some devices. The Action Bar replaces the title bar and provides an alternate location for an on-screen menu button on some devices.

Constant Value: 8 (0x00000008)

public static final int FEATURE_ACTION_BAR_OVERLAY

Added in API level 11

Flag for requesting an Action Bar that overlays window content. Normally an Action Bar will sit in the space above window content, but if this feature is requested along with FEATURE_ACTION_BAR it will be layered over the window content itself. This is useful if you would like your app to have more control over how the Action Bar is displayed, such as letting application content scroll beneath an Action Bar with a transparent background or otherwise displaying a transparent/translucent Action Bar over application content.

This mode is especially useful with View.SYSTEM_UI_FLAG_FULLSCREEN, which allows you to seamlessly hide the action bar in conjunction with other screen decorations.

As of JELLY_BEAN, when an ActionBar is in this mode it will adjust the insets provided to View.fitSystemWindows(Rect) to include the content covered by the action bar, so you can do layout within that space.

Constant Value: 9 (0x00000009)

public static final int FEATURE_ACTION_MODE_OVERLAY

Added in API level 11

Flag for specifying the behavior of action modes when an Action Bar is not present. If overlay is enabled, the action mode UI will be allowed to cover existing window content.

public static final int FEATURE_CONTENT_TRANSITIONS

Added in API level 21

Flag for requesting that window content changes should be animated using a TransitionManager.
