↳ | android.view.Window |
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.

The default features enabled
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.
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.
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.
Flag for requesting that window content changes should be represented with scenes and transitions. TODO Add docs
Flag for the context menu. This is enabled by default.
Flag for custom title. You cannot combine this feature with other title features.
Flag for indeterminate progress
Flag for having an icon on the left side of the title bar
Flag for the "no title" feature, turning off the title at the top of the screen.
Flag for the "options panel" feature. This is enabled by default.
Flag for the progress indicator feature
Flag for having an icon on the right side of the title bar
Flag for requesting a decoration-free window that is dismissed by swiping from the left.
The ID that the main layout in the XML layout file should have.
Ending value for the (primary) progress
Flag for setting the progress bar's indeterminate mode off
Flag for setting the progress bar's indeterminate mode on
Highest possible value for the secondary progress
Lowest possible value for the secondary progress
Starting value for the (primary) progress
Flag for setting the progress bar's visibility to GONE
Flag for setting the progress bar's visibility to VISIBLE

overlaps with the exit
transition of the calling Activity. When true, the transition will start as soon as possible.
When false, the transition will wait until the remote exiting transition completes before
starting.

.
Returns the transition used to move Views into the initial scene. The entering
Views will be those that are regular Views or ViewGroups that have

Take ownership of this window's InputQueue. The window will no longer read and dispatch input events from the queue; it is your responsibility to do so.
Request that key events come to this activity. Use this if your activity has no views with focus, but the activity still wants a chance to process key events.
Take ownership of this window's surface. The window's view hierarchy will no longer draw into the surface, though it will otherwise continue to operate (such as for receiving input events). The given SurfaceHolder callback will be used to tell you about state changes to the surface.
Return the feature bits that are enabled. This is the set of features that were given to requestFeature(), and are being handled by this Window itself or its container. That is, it is the set of requested features that you can actually use.
To do: add a public version of this API that allows you to check for features by their feature ID.
Return the window flags that have been explicitly set by the client,
so will not be modified by getDecorView()
