UiModeManager

public class UiModeManager
extends Object

java.lang.Object
   ↳ android.app.UiModeManager


This class provides access to the system uimode services. These services allow applications to control UI modes of the device. It provides functionality to disable the car mode and it gives access to the night mode settings.

These facilities are built on top of the underlying ACTION_DOCK_EVENT broadcasts that are sent when the user physical places the device into and out of a dock. When that happens, the UiModeManager switches the system Configuration to the appropriate UI mode, sends broadcasts about the mode switch, and starts the corresponding mode activity if appropriate. See the broadcasts ACTION_ENTER_CAR_MODE and ACTION_ENTER_DESK_MODE for more information.

In addition, the user may manually switch the system to car mode without physically being in a dock. While in car mode -- whether by manual action from the user or being physically placed in a dock -- a notification is displayed allowing the user to exit dock mode. Thus the dock mode represented here may be different than the current state of the underlying dock event broadcast.

You do not instantiate this class directly; instead, retrieve it through Context.getSystemService(Context.UI_MODE_SERVICE).

Summary

Constants

int DISABLE_CAR_MODE_GO_HOME

Flag for use with disableCarMode(int): go to the normal home activity as part of the disable.

int ENABLE_CAR_MODE_ALLOW_SLEEP

Flag for use with enableCarMode(int): allow sleep mode while in car mode.

int ENABLE_CAR_MODE_GO_CAR_HOME

Flag for use with enableCarMode(int): go to the car home activity as part of the enable.

int MODE_NIGHT_AUTO

Constant for setNightMode(int) and getNightMode(): automatically switch night mode on and off based on the time.

int MODE_NIGHT_NO

Constant for setNightMode(int) and getNightMode(): never run in night mode.

int MODE_NIGHT_YES

Constant for setNightMode(int) and getNightMode(): always run in night mode.

Fields

public static String ACTION_ENTER_CAR_MODE

Broadcast sent when the device's UI has switched to car mode, either by being placed in a car dock or explicit action of the user.

public static String ACTION_ENTER_DESK_MODE

Broadcast sent when the device's UI has switched to desk mode, by being placed in a desk dock.

public static String ACTION_EXIT_CAR_MODE

Broadcast sent when the device's UI has switch away from car mode back to normal mode.

public static String ACTION_EXIT_DESK_MODE

Broadcast sent when the device's UI has switched away from desk mode back to normal mode.

Public methods

void disableCarMode(int flags)

Turn off special mode if currently in car mode.

void enableCarMode(int flags)

Force device into car mode, like it had been placed in the car dock.

int getCurrentModeType()

Return the current running mode type.

int getNightMode()

Returns the currently configured night mode.

void setNightMode(int mode)

Sets the night mode.

Constants

DISABLE_CAR_MODE_GO_HOME

Added in API level 8
int DISABLE_CAR_MODE_GO_HOME

Flag for use with disableCarMode(int): go to the normal home activity as part of the disable. Disabling this way ensures a clean transition between the current activity (in car mode) and the original home activity (which was typically last running without being in car mode).

Constant Value: 1 (0x00000001)

ENABLE_CAR_MODE_ALLOW_SLEEP

Added in API level 21
int ENABLE_CAR_MODE_ALLOW_SLEEP

Flag for use with enableCarMode(int): allow sleep mode while in car mode. By default, when this flag is not set, the system may hold a full wake lock to keep the screen turned on and prevent the system from entering sleep mode while in car mode. Setting this flag disables such behavior and the system may enter sleep mode if there is no other user activity and no other wake lock held. Setting this flag can be relevant for a car dock application that does not require the screen kept on.

Constant Value: 2 (0x00000002)

ENABLE_CAR_MODE_GO_CAR_HOME

Added in API level 8
int ENABLE_CAR_MODE_GO_CAR_HOME

Flag for use with enableCarMode(int): go to the car home activity as part of the enable. Enabling this way ensures a clean transition between the current activity (in non-car-mode) and the car home activity that will serve as home while in car mode. This will switch to the car home activity even if we are already in car mode.

Constant Value: 1 (0x00000001)

MODE_NIGHT_AUTO

Added in API level 8
int MODE_NIGHT_AUTO

Constant for setNightMode(int) and getNightMode(): automatically switch night mode on and off based on the time.

Constant Value: 0 (0x00000000)

MODE_NIGHT_NO

Added in API level 8
int MODE_NIGHT_NO

Constant for setNightMode(int) and getNightMode(): never run in night mode.

Constant Value: 1 (0x00000001)

MODE_NIGHT_YES

Added in API level 8
int MODE_NIGHT_YES

Constant for setNightMode(int) and getNightMode(): always run in night mode.

Constant Value: 2 (0x00000002)

Fields

ACTION_ENTER_CAR_MODE

Added in API level 8
String ACTION_ENTER_CAR_MODE

Broadcast sent when the device's UI has switched to car mode, either by being placed in a car dock or explicit action of the user. After sending the broadcast, the system will start the intent ACTION_MAIN with category CATEGORY_CAR_DOCK to display the car UI, which typically what an application would implement to provide their own interface. However, applications can also monitor this Intent in order to be informed of mode changes or prevent the normal car UI from being displayed by setting the result of the broadcast to RESULT_CANCELED.

ACTION_ENTER_DESK_MODE

Added in API level 8
String ACTION_ENTER_DESK_MODE

Broadcast sent when the device's UI has switched to desk mode, by being placed in a desk dock. After sending the broadcast, the system will start the intent ACTION_MAIN with category CATEGORY_DESK_DOCK to display the desk UI, which typically what an application would implement to provide their own interface. However, applications can also monitor this Intent in order to be informed of mode changes or prevent the normal desk UI from being displayed by setting the result of the broadcast to RESULT_CANCELED.

ACTION_EXIT_CAR_MODE

Added in API level 8
String ACTION_EXIT_CAR_MODE

Broadcast sent when the device's UI has switch away from car mode back to normal mode. Typically used by a car mode app, to dismiss itself when the user exits car mode.

ACTION_EXIT_DESK_MODE

Added in API level 8
String ACTION_EXIT_DESK_MODE

Broadcast sent when the device's UI has switched away from desk mode back to normal mode. Typically used by a desk mode app, to dismiss itself when the user exits desk mode.

Public methods

disableCarMode

Added in API level 8
void disableCarMode (int flags)

Turn off special mode if currently in car mode.

Parameters
flags int: May be 0 or DISABLE_CAR_MODE_GO_HOME.

enableCarMode

Added in API level 8
void enableCarMode (int flags)

Force device into car mode, like it had been placed in the car dock. This will cause the device to switch to the car home UI as part of the mode switch.

Parameters
flags int: Must be 0.

getNightMode

Added in API level 8
int getNightMode ()

Returns the currently configured night mode.

May be one of:

Returns
int the current night mode, or -1 on error

See also:

setNightMode

Added in API level 8
void setNightMode (int mode)

Sets the night mode.

The mode can be one of:

  • MODE_NIGHT_NO sets the device into notnight mode
  • MODE_NIGHT_YES sets the device into night mode
  • MODE_NIGHT_AUTO automatically switches between night and notnight based on the device's current location and certain other sensors

Note: On API 22 and below, changes to the night mode are only effective when the car or desk mode is enabled on a device. Starting in API 23, changes to night mode are always effective.

Parameters
mode int: the night mode to set
