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.
