static val ALPHA_CHANGED: Int

Value: 128

ANIMATION_CHANGED

static val ANIMATION_CHANGED: Int

Value: 16

BRIGHTNESS_OVERRIDE_FULL

static val BRIGHTNESS_OVERRIDE_FULL: Float

Value for screenBrightness and buttonBrightness indicating that the screen or button backlight brightness should be set to the hightest value when this window is in front.

Value: 1.0f

BRIGHTNESS_OVERRIDE_NONE

static val BRIGHTNESS_OVERRIDE_NONE: Float

Default value for screenBrightness and buttonBrightness indicating that the brightness value is not overridden for this window and normal brightness policy should be used.

Value: -1.0f

BRIGHTNESS_OVERRIDE_OFF

static val BRIGHTNESS_OVERRIDE_OFF: Float

Value for screenBrightness and buttonBrightness indicating that the screen or button backlight brightness should be set to the lowest value when this window is in front.

Value: 0.0f

DIM_AMOUNT_CHANGED

static val DIM_AMOUNT_CHANGED: Int

Value: 32

DISPLAY_FLAG_DISABLE_HDR_CONVERSION

static val DISPLAY_FLAG_DISABLE_HDR_CONVERSION: Int

Indicates whether this window wants the HDR conversion is disabled.

Value: 1

FIRST_APPLICATION_WINDOW

static val FIRST_APPLICATION_WINDOW: Int

Start of window types that represent normal application windows.

Value: 1

FIRST_SUB_WINDOW

static val FIRST_SUB_WINDOW: Int

Start of types of sub-windows. The token of these windows must be set to the window they are attached to. These types of windows are kept next to their attached window in Z-order, and their coordinate space is relative to their attached window.

Value: 1000

FIRST_SYSTEM_WINDOW

static val FIRST_SYSTEM_WINDOW: Int

Start of system-specific window types. These are not normally created by applications.

Value: 2000

FLAGS_CHANGED

static val FLAGS_CHANGED: Int

Value: 4

FLAG_ALLOW_LOCK_WHILE_SCREEN_ON

static val FLAG_ALLOW_LOCK_WHILE_SCREEN_ON: Int

Window flag: as long as this window is visible to the user, allow the lock screen to activate while the screen is on. This can be used independently, or in combination with FLAG_KEEP_SCREEN_ON and/or FLAG_SHOW_WHEN_LOCKED

Value: 1

FLAG_ALT_FOCUSABLE_IM

static val FLAG_ALT_FOCUSABLE_IM: Int

Window flag: when set, inverts the input method focusability of the window. The effect of setting this flag depends on whether FLAG_NOT_FOCUSABLE is set:

If FLAG_NOT_FOCUSABLE is not set, i.e. when the window is focusable, setting this flag prevents this window from becoming the target of the input method. Consequently, it will not be able to interact with the input method, and will be layered above the input method (unless there is another input method target above it).

If FLAG_NOT_FOCUSABLE is set, setting this flag requests for the window to be the input method target even though the window is not focusable. Consequently, it will be layered below the input method. Note: Windows that set FLAG_NOT_FOCUSABLE cannot interact with the input method, regardless of this flag.

Value: 131072

FLAG_BLUR_BEHIND

static val FLAG_BLUR_BEHIND: Int

Window flag: enable blur behind for this window.

Value: 4

FLAG_DIM_BEHIND

static val FLAG_DIM_BEHIND: Int

Window flag: everything behind this window will be dimmed. Use dimAmount to control the amount of dim.

Value: 2

FLAG_DISMISS_KEYGUARD

static val FLAG_DISMISS_KEYGUARD: Int

Deprecated: Use FLAG_SHOW_WHEN_LOCKED or KeyguardManager#requestDismissKeyguard instead. Since keyguard was dismissed all the time as long as an activity with this flag on its window was focused, keyguard couldn't guard against unintentional touches on the screen, which isn't desired.

Window flag: when set the window will cause the keyguard to be dismissed, only if it is not a secure lock keyguard. Because such a keyguard is not needed for security, it will never re-appear if the user navigates to another window (in contrast to FLAG_SHOW_WHEN_LOCKED, which will only temporarily hide both secure and non-secure keyguards but ensure they reappear when the user moves to another UI that doesn't hide them). If the keyguard is currently active and is secure (requires an unlock credential) than the user will still need to confirm it before seeing this window, unless FLAG_SHOW_WHEN_LOCKED has also been set.

Value: 4194304

FLAG_DITHER

static val FLAG_DITHER: Int

Deprecated: This flag is no longer used.

Window flag: turn on dithering when compositing this window to the screen.

Value: 4096

FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS

static val FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS: Int

Flag indicating that this Window is responsible for drawing the background for the system bars. If set, the system bars are drawn with a transparent background and the corresponding areas in this window are filled with the colors specified in Window#getStatusBarColor() and Window#getNavigationBarColor().

Value: -2147483648

FLAG_FORCE_NOT_FULLSCREEN

static val FLAG_FORCE_NOT_FULLSCREEN: Int

Deprecated: This value became API "by accident", and shouldn't be used by 3rd party applications.

Window flag: override FLAG_FULLSCREEN and force the screen decorations (such as the status bar) to be shown.

Value: 2048

FLAG_FULLSCREEN

static val FLAG_FULLSCREEN: Int

Deprecated: Use WindowInsetsController#hide(int) with Type#statusBars() instead.

Window flag: hide all screen decorations (such as the status bar) while this window is displayed. This allows the window to use the entire display space for itself -- the status bar will be hidden when an app window with this flag set is on the top layer. A fullscreen window will ignore a value of SOFT_INPUT_ADJUST_RESIZE for the window's softInputMode field; the window will stay fullscreen and will not resize.

This flag can be controlled in your theme through the android.R.attr#windowFullscreen attribute; this attribute is automatically set for you in the standard fullscreen themes such as android.R.style#Theme_NoTitleBar_Fullscreen, android.R.style#Theme_Black_NoTitleBar_Fullscreen, android.R.style#Theme_Light_NoTitleBar_Fullscreen, android.R.style#Theme_Holo_NoActionBar_Fullscreen, android.R.style#Theme_Holo_Light_NoActionBar_Fullscreen, android.R.style#Theme_DeviceDefault_NoActionBar_Fullscreen, and android.R.style#Theme_DeviceDefault_Light_NoActionBar_Fullscreen.

Value: 1024

FLAG_HARDWARE_ACCELERATED

static val FLAG_HARDWARE_ACCELERATED: Int

Indicates whether this window should be hardware accelerated. Requesting hardware acceleration does not guarantee it will happen.

This flag can be controlled programmatically only to enable hardware acceleration. To enable hardware acceleration for a given window programmatically, do the following:

Window w = activity.getWindow(); // in Activity's onCreate() for instance
  w.setFlags(WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
          WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
  

It is important to remember that this flag must be set before setting the content view of your activity or dialog.

This flag cannot be used to disable hardware acceleration after it was enabled in your manifest using android.R.attr#hardwareAccelerated. If you need to selectively and programmatically disable hardware acceleration (for automated testing for instance), make sure it is turned off in your manifest and enable it on your activity or dialog when you need it instead, using the method described above.

This flag is automatically set by the system if the android:hardwareAccelerated XML attribute is set to true on an activity or on the application.

Value: 16777216

FLAG_IGNORE_CHEEK_PRESSES

static val FLAG_IGNORE_CHEEK_PRESSES: Int

Window flag: intended for windows that will often be used when the user is holding the screen against their face, it will aggressively filter the event stream to prevent unintended presses in this situation that may not be desired for a particular window, when such an event stream is detected, the application will receive a CANCEL motion event to indicate this so applications can handle this accordingly by taking no action on the event until the finger is released.

Value: 32768

FLAG_KEEP_SCREEN_ON

static val FLAG_KEEP_SCREEN_ON: Int

Window flag: as long as this window is visible to the user, keep the device's screen turned on and bright.

Value: 128

FLAG_LAYOUT_ATTACHED_IN_DECOR

static val FLAG_LAYOUT_ATTACHED_IN_DECOR: Int

Deprecated: Use setFitInsetsTypes(int) to determine whether the attached window will overlap with system bars.

Window flag: When requesting layout with an attached window, the attached window may overlap with the screen decorations of the parent window such as the navigation bar. By including this flag, the window manager will layout the attached window within the decor frame of the parent window such that it doesn't overlap with screen decorations.

Value: 1073741824

FLAG_LAYOUT_INSET_DECOR

static val FLAG_LAYOUT_INSET_DECOR: Int

Deprecated: Insets will always be delivered to your application.

Window flag: a special option only for use in combination with FLAG_LAYOUT_IN_SCREEN. When requesting layout in the screen your window may appear on top of or behind screen decorations such as the status bar. By also including this flag, the window manager will report the inset rectangle needed to ensure your content is not covered by screen decorations. This flag is normally set for you by Window as described in Window#setFlags

Value: 65536

FLAG_LAYOUT_IN_OVERSCAN

static val FLAG_LAYOUT_IN_OVERSCAN: Int

Deprecated: Overscan areas aren't set by any Android product anymore as of Android 11.

Window flag: allow window contents to extend in to the screen's overscan area, if there is one. The window should still correctly position its contents to take the overscan area into account.

This flag can be controlled in your theme through the android.R.attr#windowOverscan attribute; this attribute is automatically set for you in the standard overscan themes such as android.R.style#Theme_Holo_NoActionBar_Overscan, android.R.style#Theme_Holo_Light_NoActionBar_Overscan, android.R.style#Theme_DeviceDefault_NoActionBar_Overscan, and android.R.style#Theme_DeviceDefault_Light_NoActionBar_Overscan.

When this flag is enabled for a window, its normal content may be obscured to some degree by the overscan region of the display. To ensure key parts of that content are visible to the user, you can use View.setFitsSystemWindows(boolean) to set the point in the view hierarchy where the appropriate offsets should be applied. (This can be done either by directly calling this function, using the android.R.attr#fitsSystemWindows attribute in your view hierarchy, or implementing you own View.fitSystemWindows(Rect) method).

This mechanism for positioning content elements is identical to its equivalent use with layout and View.setSystemUiVisibility(int); here is an example layout that will correctly position its UI elements with this overscan flag is set:

Value: 33554432

FLAG_LAYOUT_IN_SCREEN

static val FLAG_LAYOUT_IN_SCREEN: Int

Window flag for attached windows: Place the window within the entire screen, ignoring any constraints from the parent window.

Note: on displays that have a DisplayCutout, the window may be placed such that it avoids the DisplayCutout area if necessary according to the layoutInDisplayCutoutMode.

Value: 256

FLAG_LAYOUT_NO_LIMITS

static val FLAG_LAYOUT_NO_LIMITS: Int

Window flag: allow window to extend outside of the screen.

Value: 512

FLAG_LOCAL_FOCUS_MODE

static val FLAG_LOCAL_FOCUS_MODE: Int

Flag for a window in local focus mode. Window in local focus mode can control focus independent of window manager using Window#setLocalFocus(boolean, boolean). Usually window in this mode will not get touch/key events from window manager, but will get events only via local injection using Window#injectInputEvent(InputEvent).

Value: 268435456

FLAG_NOT_FOCUSABLE

static val FLAG_NOT_FOCUSABLE: Int

Window flag: this window won't ever get key input focus, so the user can not send key or other button events to it. Those will instead go to whatever focusable window is behind it. This flag will also enable FLAG_NOT_TOUCH_MODAL whether or not that is explicitly set.

Setting this flag also implies that the window will not need to interact with a soft input method, so it will be Z-ordered and positioned independently of any active input method (typically this means it gets Z-ordered on top of the input method, so it can use the full screen for its content and cover the input method if needed. You can use FLAG_ALT_FOCUSABLE_IM to modify this behavior.

Value: 8

FLAG_NOT_TOUCHABLE

static val FLAG_NOT_TOUCHABLE: Int

Window flag: this window can never receive touch events.

The intention of this flag is to leave the touch to be handled by some window below this window (in Z order).

Starting from Android Build.VERSION_CODES#S, for security reasons, touch events that pass through windows containing this flag (ie. are within the bounds of the window) will only be delivered to the touch-consuming window if one (or more) of the items below are true:

1. Same UID: This window belongs to the same UID that owns the touch-consuming window.
2. Trusted windows: This window is trusted. Trusted windows include (but are not limited to) accessibility windows (TYPE_ACCESSIBILITY_OVERLAY), the IME (TYPE_INPUT_METHOD) and assistant windows (TYPE_VOICE_INTERACTION). Windows of type TYPE_APPLICATION_OVERLAY are not trusted, see below.
3. Invisible windows: This window is View#GONE or View#INVISIBLE.
4. Fully transparent windows: This window has LayoutParams#alpha equal to 0.
5. One SAW window with enough transparency: This window is of type TYPE_APPLICATION_OVERLAY, has LayoutParams#alpha below or equal to the maximum obscuring opacity (see below) and it's the only window of type TYPE_APPLICATION_OVERLAY from this UID in the touch path.
6. Multiple SAW windows with enough transparency: The multiple overlapping TYPE_APPLICATION_OVERLAY windows in the touch path from this UID have a combined obscuring opacity below or equal to the maximum obscuring opacity. See section Combined obscuring opacity below on how to compute this value.

If none of these cases hold, the touch will not be delivered and a message will be logged to logcat.

Maximum obscuring opacity

This value is 0.8. Apps that want to gather this value from the system rather than hard-coding it might want to use android.hardware.input.InputManager#getMaximumObscuringOpacityForTouch().

Combined obscuring opacity

The combined obscuring opacity of a set of windows is obtained by combining the opacity values of all windows in the set using the associative and commutative operation defined as:

opacity({A,B}) = 1 - (1 - opacity(A))*(1 - opacity(B))
  

where opacity(X) is the LayoutParams#alpha of window X. So, for a set of windows {W1, .., Wn}, the combined obscuring opacity will be:

opacity({W1, .., Wn}) = 1 - (1 - opacity(W1)) * ... * (1 - opacity(Wn))
  

Value: 16

FLAG_NOT_TOUCH_MODAL

static val FLAG_NOT_TOUCH_MODAL: Int

Window flag: even when this window is focusable (its FLAG_NOT_FOCUSABLE is not set), allow any pointer events outside of the window to be sent to the windows behind it. Otherwise it will consume all pointer events itself, regardless of whether they are inside of the window.

Value: 32

FLAG_SCALED

static val FLAG_SCALED: Int

Window flag: a special mode where the layout parameters are used to perform scaling of the surface when it is composited to the screen.

Value: 16384

FLAG_SECURE

static val FLAG_SECURE: Int

Window flag: treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays.

See android.view.View#setContentSensitivity(int), a window hosting a sensitive view will be marked as secure during media projection, preventing it from being viewed on non-secure displays and during screen share.

See android.view.Display#FLAG_SECURE for more details about secure surfaces and secure displays.

Value: 8192

FLAG_SHOW_WALLPAPER

static val FLAG_SHOW_WALLPAPER: Int

Window flag: ask that the system wallpaper be shown behind your window. The window surface must be translucent to be able to actually see the wallpaper behind it; this flag just ensures that the wallpaper surface will be there if this window actually has translucent regions.

This flag can be controlled in your theme through the android.R.attr#windowShowWallpaper attribute; this attribute is automatically set for you in the standard wallpaper themes such as android.R.style#Theme_Wallpaper, android.R.style#Theme_Wallpaper_NoTitleBar, android.R.style#Theme_Wallpaper_NoTitleBar_Fullscreen, android.R.style#Theme_Holo_Wallpaper, android.R.style#Theme_Holo_Wallpaper_NoTitleBar, android.R.style#Theme_DeviceDefault_Wallpaper, and android.R.style#Theme_DeviceDefault_Wallpaper_NoTitleBar.

When this flag is set, all touch events sent to this window is also sent to the wallpaper, which is used to interact with live wallpapers. Check LayoutParams#areWallpaperTouchEventsEnabled(), which is set to true by default. When showing sensitive information on the window, if you want to disable sending the touch events to the wallpaper, use LayoutParams#setWallpaperTouchEventsEnabled(boolean).

Value: 1048576

FLAG_SHOW_WHEN_LOCKED

static val FLAG_SHOW_WHEN_LOCKED: Int

Deprecated: Use android.R.attr#showWhenLocked or android.app.Activity#setShowWhenLocked(boolean) instead to prevent an unintentional double life-cycle event.

Window flag: special flag to let windows be shown when the screen is locked. This will let application windows take precedence over key guard or any other lock screens. Can be used with FLAG_KEEP_SCREEN_ON to turn screen on and display windows directly before showing the key guard window. Can be used with FLAG_DISMISS_KEYGUARD to automatically fully dismisss non-secure keyguards. This flag only applies to the top-most full-screen window.

Value: 524288

FLAG_SPLIT_TOUCH

static val FLAG_SPLIT_TOUCH: Int

Window flag: when set the window will accept for touch events outside of its bounds to be sent to other windows that also support split touch. When this flag is not set, the first pointer that goes down determines the window to which all subsequent touches go until all pointers go up. When this flag is set, each pointer (not necessarily the first) that goes down determines the window to which all subsequent touches of that pointer will go until that pointer goes up thereby enabling touches with multiple pointers to be split across multiple windows.

Value: 8388608

FLAG_TOUCHABLE_WHEN_WAKING

static val FLAG_TOUCHABLE_WHEN_WAKING: Int

Deprecated: This flag has no effect.

Window flag: when set, if the device is asleep when the touch screen is pressed, you will receive this first touch event. Usually the first touch event is consumed by the system since the user can not see what they are pressing on.

Value: 64

FLAG_TRANSLUCENT_NAVIGATION

static val FLAG_TRANSLUCENT_NAVIGATION: Int

Deprecated: Use Window#setNavigationBarColor(int) with a half-translucent color instead.

Window flag: request a translucent navigation bar with minimal system-provided background protection.

This flag can be controlled in your theme through the android.R.attr#windowTranslucentNavigation attribute; this attribute is automatically set for you in the standard translucent decor themes such as android.R.style#Theme_Holo_NoActionBar_TranslucentDecor, android.R.style#Theme_Holo_Light_NoActionBar_TranslucentDecor, android.R.style#Theme_DeviceDefault_NoActionBar_TranslucentDecor, and android.R.style#Theme_DeviceDefault_Light_NoActionBar_TranslucentDecor.

When this flag is enabled for a window, it automatically sets the system UI visibility flags View#SYSTEM_UI_FLAG_LAYOUT_STABLE and View#SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION.

Note: For devices that support android.content.pm.PackageManager#FEATURE_AUTOMOTIVE this flag can be disabled by the car manufacturers.

Value: 134217728

FLAG_TRANSLUCENT_STATUS

static val FLAG_TRANSLUCENT_STATUS: Int

Deprecated: Use Window#setStatusBarColor(int) with a half-translucent color instead.

Window flag: request a translucent status bar with minimal system-provided background protection.

This flag can be controlled in your theme through the android.R.attr#windowTranslucentStatus attribute; this attribute is automatically set for you in the standard translucent decor themes such as android.R.style#Theme_Holo_NoActionBar_TranslucentDecor, android.R.style#Theme_Holo_Light_NoActionBar_TranslucentDecor, android.R.style#Theme_DeviceDefault_NoActionBar_TranslucentDecor, and android.R.style#Theme_DeviceDefault_Light_NoActionBar_TranslucentDecor.

When this flag is enabled for a window, it automatically sets the system UI visibility flags View#SYSTEM_UI_FLAG_LAYOUT_STABLE and View#SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN.

Note: For devices that support android.content.pm.PackageManager#FEATURE_AUTOMOTIVE this flag may be ignored.

Value: 67108864

FLAG_TURN_SCREEN_ON

static val FLAG_TURN_SCREEN_ON: Int

Deprecated: Use android.R.attr#turnScreenOn or android.app.Activity#setTurnScreenOn(boolean) instead to prevent an unintentional double life-cycle event.

Window flag: when set as a window is being added or made visible, once the window has been shown then the system will poke the power manager's user activity (as if the user had woken up the device) to turn the screen on.

Value: 2097152

FLAG_WATCH_OUTSIDE_TOUCH

static val FLAG_WATCH_OUTSIDE_TOUCH: Int

Window flag: if you have set FLAG_NOT_TOUCH_MODAL, you can set this flag to receive a single special MotionEvent with the action MotionEvent.ACTION_OUTSIDE for touches that occur outside of your window. Note that you will not receive the full down/move/up gesture, only the location of the first down as an ACTION_OUTSIDE.

Value: 262144

FORMAT_CHANGED

static val FORMAT_CHANGED: Int

Value: 8

LAST_APPLICATION_WINDOW

static val LAST_APPLICATION_WINDOW: Int

End of types of application windows.

Value: 99

LAST_SUB_WINDOW

static val LAST_SUB_WINDOW: Int

End of types of sub-windows.

Value: 1999

LAST_SYSTEM_WINDOW

static val LAST_SYSTEM_WINDOW: Int

Value: 2999

LAYOUT_CHANGED

static val LAYOUT_CHANGED: Int

Value: 1

LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS

static val LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS: Int

The window is always allowed to extend into the DisplayCutout areas on the all edges of the screen.

The window must make sure that no important content overlaps with the DisplayCutout.

In this mode, the window extends under cutouts on the all edges of the display in both portrait and landscape, regardless of whether the window is hiding the system bars.

Note: Android might not allow the content view to overlap the system bars in view level. To override this behavior and allow content to be able to extend into the cutout area, call Window#setDecorFitsSystemWindows(boolean) with false.

Value: 3

LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT

static val LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT: Int

The window is allowed to extend into the DisplayCutout area, only if the DisplayCutout is fully contained within a system bar or the DisplayCutout is not deeper than 16 dp, but this depends on the OEM choice. Otherwise, the window is laid out such that it does not overlap with the DisplayCutout area.

In practice, this means that if the window did not set FLAG_FULLSCREEN or View#SYSTEM_UI_FLAG_FULLSCREEN, it can extend into the cutout area in portrait if the cutout is at the top edge. Similarly for View#SYSTEM_UI_FLAG_HIDE_NAVIGATION and a cutout at the bottom of the screen. Otherwise (i.e. fullscreen or landscape) it is laid out such that it does not overlap the cutout area.

The usual precautions for not overlapping with the status and navigation bar are sufficient for ensuring that no important content overlaps with the DisplayCutout.

Note: OEMs can have an option to allow the window to always extend into the DisplayCutout area, no matter the cutout flag set, when the DisplayCutout is on the different side from system bars, only if the DisplayCutout overlaps at most 16dp with the windows. In such case, OEMs must provide an opt-in/out affordance for users.

Value: 0

LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER

static val LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER: Int

The window is never allowed to overlap with the DisplayCutout area.

This should be used with windows that transiently set View#SYSTEM_UI_FLAG_FULLSCREEN or View#SYSTEM_UI_FLAG_HIDE_NAVIGATION to avoid a relayout of the window when the respective flag is set or cleared.

Value: 2

LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES

static val LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES: Int

The window is always allowed to extend into the DisplayCutout areas on the short edges of the screen.

The window will never extend into a DisplayCutout area on the long edges of the screen, unless the DisplayCutout is not deeper than 16 dp, but this depends on the OEM choice.

Note: OEMs can have an option to allow the window to extend into the DisplayCutout area on the long edge side, only if the cutout overlaps at most 16dp with the windows. In such case, OEMs must provide an opt-in/out affordance for users.

The window must make sure that no important content overlaps with the DisplayCutout.

In this mode, the window extends under cutouts on the short edge of the display in both portrait and landscape, regardless of whether the window is hiding the system bars:

A cutout in the corner can be considered to be on different edge in different device rotations. This behavior may vary from device to device. Use this flag is possible to letterbox your app if the display cutout is at corner.

On the other hand, should the cutout be on the long edge of the display, a letterbox will be applied such that the window does not extend into the cutout on either long edge:

Note: Android might not allow the content view to overlap the system bars in view level. To override this behavior and allow content to be able to extend into the cutout area, call Window#setDecorFitsSystemWindows(boolean) with false.

ROTATION_ANIMATION_CHANGED

static val ROTATION_ANIMATION_CHANGED: Int

Value: 4096

ROTATION_ANIMATION_CROSSFADE

static val ROTATION_ANIMATION_CROSSFADE: Int

Value for rotationAnimation which specifies that this window will fade in or out following a rotation.

Value: 1

ROTATION_ANIMATION_JUMPCUT

static val ROTATION_ANIMATION_JUMPCUT: Int

Value for rotationAnimation which specifies that this window will immediately disappear or appear following a rotation.

Value: 2

ROTATION_ANIMATION_ROTATE

static val ROTATION_ANIMATION_ROTATE: Int

Value for rotationAnimation which specifies that this window will visually rotate in or out following a rotation.

Value: 0

ROTATION_ANIMATION_SEAMLESS

static val ROTATION_ANIMATION_SEAMLESS: Int

Value for rotationAnimation to specify seamless rotation mode. This works like JUMPCUT but will fall back to CROSSFADE if rotation can't be applied without pausing the screen. For example, this is ideal for Camera apps which don't want the viewfinder contents to ever rotate or fade (and rather to be seamless) but also don't want ROTATION_ANIMATION_JUMPCUT during app transition scenarios where seamless rotation can't be applied.

Value: 3

SCREEN_ORIENTATION_CHANGED

static val SCREEN_ORIENTATION_CHANGED: Int

Value: 1024

SOFT_INPUT_ADJUST_NOTHING

static val SOFT_INPUT_ADJUST_NOTHING: Int

Adjustment option for softInputMode: set to have a window not adjust for a shown input method. The window will not be resized, and it will not be panned to make its focus visible.

Value: 48

SOFT_INPUT_ADJUST_PAN

static val SOFT_INPUT_ADJUST_PAN: Int

Adjustment option for softInputMode: set to have a window pan when an input method is shown, so it doesn't need to deal with resizing but just panned by the framework to ensure the current input focus is visible. This can not be combined with SOFT_INPUT_ADJUST_RESIZE; if neither of these are set, then the system will try to pick one or the other depending on the contents of the window.

Value: 32

SOFT_INPUT_ADJUST_RESIZE

static val SOFT_INPUT_ADJUST_RESIZE: Int

Deprecated: Call Window#setDecorFitsSystemWindows(boolean) with false and install an OnApplyWindowInsetsListener on your root content view that fits insets of type Type#ime().

Adjustment option for softInputMode: set to allow the window to be resized when an input method is shown, so that its contents are not covered by the input method. This can not be combined with SOFT_INPUT_ADJUST_PAN; if neither of these are set, then the system will try to pick one or the other depending on the contents of the window. If the window's layout parameter flags include FLAG_FULLSCREEN, this value for softInputMode will be ignored; the window will not resize, but will stay fullscreen.

Value: 16

SOFT_INPUT_ADJUST_UNSPECIFIED

static val SOFT_INPUT_ADJUST_UNSPECIFIED: Int

Adjustment option for softInputMode: nothing specified. The system will try to pick one or the other depending on the contents of the window.

Value: 0

SOFT_INPUT_IS_FORWARD_NAVIGATION

static val SOFT_INPUT_IS_FORWARD_NAVIGATION: Int

Bit for softInputMode: set when the user has navigated forward to the window. This is normally set automatically for you by the system, though you may want to set it in certain cases when you are displaying a window yourself. This flag will always be cleared automatically after the window is displayed.

Value: 256

SOFT_INPUT_MASK_ADJUST

static val SOFT_INPUT_MASK_ADJUST: Int

Mask for softInputMode of the bits that determine the way that the window should be adjusted to accommodate the soft input window.

Value: 240

Value: 3

SOFT_INPUT_STATE_ALWAYS_VISIBLE

static val SOFT_INPUT_STATE_ALWAYS_VISIBLE: Int

Visibility state for softInputMode: please always make the soft input area visible when this window receives input focus.

Applications that target android.os.Build.VERSION_CODES#P and later, this flag is ignored unless there is a focused view that returns true from View#onCheckIsTextEditor() when the window is focused.

Value: 5

SOFT_INPUT_STATE_HIDDEN

static val SOFT_INPUT_STATE_HIDDEN: Int

Visibility state for softInputMode: please hide any soft input area when normally appropriate (when the user is navigating forward to your window).

mayUseInputMethod

open static fun mayUseInputMethod(flags: Int): Boolean

Given a particular set of window manager flags, determine whether such a window may be a target for an input method when it has focus. In particular, this checks the FLAG_NOT_FOCUSABLE and FLAG_ALT_FOCUSABLE_IM flags and returns true if the combination of the two corresponds to a window that can use the input method.

setBlurBehindRadius

open fun setBlurBehindRadius(blurBehindRadius: Int): Unit

Blurs the screen behind the window. The effect is similar to that of dimAmount, but instead of dimmed, the content behind the window will be blurred (or combined with the dim amount, if such is specified).

The density of the blur is set by the blur radius. The radius defines the size of the neighbouring area, from which pixels will be averaged to form the final color for each pixel. The operation approximates a Gaussian blur. A radius of 0 means no blur. The higher the radius, the denser the blur.

Note the difference with android.view.Window#setBackgroundBlurRadius, which blurs only within the bounds of the window. Blur behind blurs the whole screen behind the window.

Requires FLAG_BLUR_BEHIND to be set.

Cross-window blur might not be supported by some devices due to GPU limitations. It can also be disabled at runtime, e.g. during battery saving mode, when multimedia tunneling is used or when minimal post processing is requested. In such situations, no blur will be computed or drawn, resulting in there being no depth separation between the window and the content behind it. To avoid this, the app might want to use more dimAmount on its window. To listen for cross-window blur enabled/disabled events, use #addCrossWindowBlurEnabledListener.

setCanPlayMoveAnimation

open fun setCanPlayMoveAnimation(enable: Boolean): Unit

Set whether animations can be played for position changes on this window. If disabled, the window will move to its new position instantly without animating.

setColorMode

The color mode must be one of ActivityInfo#COLOR_MODE_DEFAULT, ActivityInfo#COLOR_MODE_WIDE_COLOR_GAMUT or ActivityInfo#COLOR_MODE_HDR.

setDesiredHdrHeadroom

open fun setDesiredHdrHeadroom(desiredHeadroom: Float): Unit

Sets the desired about of HDR headroom to be used when rendering as a ratio of targetHdrPeakBrightnessInNits / targetSdrWhitePointInNits. Only applies when setColorMode(int) is ActivityInfo#COLOR_MODE_HDR

Controls how the window is laid out if there is a DisplayCutout.

Defaults to LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT.
Value is android.view.WindowManager.LayoutParams#LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT, android.view.WindowManager.LayoutParams#LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES, android.view.WindowManager.LayoutParams#LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER, or android.view.WindowManager.LayoutParams#LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS

memoryType

var memoryType: Int

Deprecated: this is ignored

packageName

var packageName: String!

Name of the package owning this window.

preferMinimalPostProcessing

var preferMinimalPostProcessing: Boolean

Indicates whether this window wants the connected display to do minimal post processing on the produced image or video frames. This will only be requested if the window is visible on the screen.

This setting should be used when low latency has a higher priority than image enhancement processing (e.g. for games or video conferencing).

If the Display sink is connected via HDMI, the device will begin to send infoframes with Auto Low Latency Mode enabled and Game Content Type. This will switch the connected display to a minimal image processing mode (if available), which reduces latency, improving the user experience for gaming or video conferencing applications. For more information, see HDMI 2.1 specification.

If the Display sink has an internal connection or uses some other protocol than HDMI, effects may be similar but implementation-defined.

The ability to switch to a mode with minimal post proessing may be disabled by a user setting in the system settings menu. In that case, this field is ignored and the display will remain in its current mode.

preferredDisplayModeId

var preferredDisplayModeId: Int

Id of the preferred display mode for the window.

This must be one of the supported modes obtained for the display(s) the window is on. A value of 0 means no preference.

preferredRefreshRate

var preferredRefreshRate: Float

The preferred refresh rate for the window.

Before API 34, this must be one of the supported refresh rates obtained for the display(s) the window is on. The selected refresh rate will be applied to the display's default mode.

Starting API 34, this value is not limited to the supported refresh rates obtained from the display(s) for the window: it can be any refresh rate the window intends to run at. Any refresh rate can be provided as the preferred window refresh rate. The OS will select the refresh rate that best matches the preferredRefreshRate.

Setting this value is the equivalent of calling android.view.Surface#setFrameRate with ( preferred_frame_rate, Surface#FRAME_RATE_COMPATIBILITY_DEFAULT, Surface#CHANGE_FRAME_RATE_ONLY_IF_SEAMLESS). This should be used in favor of LayoutParams#preferredDisplayModeId for applications that want to specify the refresh rate, but do not want to specify a preference for any other displayMode properties (e.g., resolution).

This value is ignored if preferredDisplayModeId is set.

rotationAnimation

var rotationAnimation: Int

Define the exit and entry animations used on this window when the device is rotated. This only has an affect if the incoming and outgoing topmost opaque windows have the #FLAG_FULLSCREEN bit set and are not covered by other windows. All other situations default to the ROTATION_ANIMATION_ROTATE behavior.

screenBrightness

var screenBrightness: Float

This can be used to override the user's preferred brightness of the screen. A value of less than 0, the default, means to use the preferred screen brightness. 0 to 1 adjusts the brightness from dark to full bright.

screenOrientation

var screenOrientation: Int

Specific orientation value for a window. May be any of the same values allowed for android.content.pm.ActivityInfo#screenOrientation. If not set, a default value of android.content.pm.ActivityInfo#SCREEN_ORIENTATION_UNSPECIFIED will be used.
Value is android.content.pm.ActivityInfo.SCREEN_ORIENTATION_UNSET, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_UNSPECIFIED, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_LANDSCAPE, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_PORTRAIT, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_USER, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_BEHIND, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_SENSOR, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_NOSENSOR, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_SENSOR_LANDSCAPE, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_SENSOR_PORTRAIT, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_REVERSE_LANDSCAPE, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_REVERSE_PORTRAIT, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_FULL_SENSOR, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_USER_LANDSCAPE, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_USER_PORTRAIT, android.content.pm.ActivityInfo#SCREEN_ORIENTATION_FULL_USER, or android.content.pm.ActivityInfo#SCREEN_ORIENTATION_LOCKED
