WindowCompatpublic class WindowCompat extends Object | Helper for accessing features in {@link Window} introduced after API
level 4 in a backwards compatible fashion. |
| Fields Summary |
|---|
| public static final int | FEATURE_ACTION_BARFlag 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. | | public static final int | FEATURE_ACTION_BAR_OVERLAYFlag 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 {@link #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 {@link View#SYSTEM_UI_FLAG_FULLSCREEN
View.SYSTEM_UI_FLAG_FULLSCREEN}, which allows you to seamlessly hide the
action bar in conjunction with other screen decorations.
As of {@link android.os.Build.VERSION_CODES#JELLY_BEAN}, when an
ActionBar is in this mode it will adjust the insets provided to
{@link View#fitSystemWindows(android.graphics.Rect) View.fitSystemWindows(Rect)}
to include the content covered by the action bar, so you can do layout within
that space. | | public static final int | FEATURE_ACTION_MODE_OVERLAYFlag 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. |
