Constants
LIGHT_CAPABILITY_BRIGHTNESS
static val LIGHT_CAPABILITY_BRIGHTNESS: Int
Capability for lights that could adjust its LED brightness. If the capability is not present the LED can only be turned either on or off.
Value: 1LIGHT_CAPABILITY_COLOR_RGB
static val LIGHT_CAPABILITY_COLOR_RGB: Int
Capability for lights that have red, green and blue LEDs to control the light's color.
Value: 2LIGHT_CAPABILITY_RGB
static valLIGHT_CAPABILITY_RGB: Int
Deprecated: Wrong int based flag with value 0. Use capability flag LIGHT_CAPABILITY_COLOR_RGB instead.
Capability for lights that have red, green and blue LEDs to control the light's color.
Value: 0LIGHT_TYPE_INPUT
static val LIGHT_TYPE_INPUT: Int
Type for lights that indicate a monochrome color LED light.
Value: 10001LIGHT_TYPE_KEYBOARD_BACKLIGHT
static val LIGHT_TYPE_KEYBOARD_BACKLIGHT: Int
Type for lights that illuminate keyboard keys.
Value: 10003LIGHT_TYPE_MICROPHONE
static val LIGHT_TYPE_MICROPHONE: Int
Type for lights that indicate microphone usage
Value: 8LIGHT_TYPE_PLAYER_ID
static val LIGHT_TYPE_PLAYER_ID: Int
Type for lights that indicate a group of LED lights representing player id. Player id lights normally present on game controllers are lights that consist of a row of LEDs. During multi-player game, the player id for the current game controller is represented by one of the LED that is lit according to its position in the row.
Value: 10002Public methods
describeContents
fun describeContents(): Int
Implement the Parcelable interface
| Return | |
|---|---|
Int | 
            a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR | 
          
equals
fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
 The equals method implements an equivalence relation on non-null object references: 
- It is reflexive: for any non-null reference value 
x,x.equals(x)should returntrue. - It is symmetric: for any non-null reference values 
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values 
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values 
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value 
x,x.equals(null)should returnfalse. 
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters | |
|---|---|
obj | 
            This value may be null. | 
          
| Return | |
|---|---|
Boolean | 
            true if this object is the same as the obj argument; false otherwise. | 
          
getId
fun getId(): Int
Returns the id of the light.
This is an opaque value used as a unique identifier for the light.
getName
fun getName(): String
Returns the name of the light.
| Return | |
|---|---|
String | 
            This value cannot be null. | 
          
getOrdinal
fun getOrdinal(): Int
Returns the ordinal of the light.
This is a sort key that represents the physical order of lights on the device with the same type. In the case of multiple lights arranged in a line, for example, the ordinals could be [1, 2, 3, 4], or [0, 10, 20, 30], or any other values that have the same sort order.
getType
fun getType(): Int
Returns the logical type of the light.
| Return | |
|---|---|
Int | 
            Value is android.hardware.lights.Light#LIGHT_TYPE_MICROPHONE, android.hardware.lights.Light#LIGHT_TYPE_INPUT, android.hardware.lights.Light#LIGHT_TYPE_PLAYER_ID, android.hardware.lights.Light#LIGHT_TYPE_KEYBOARD_BACKLIGHT, android.hardware.lights.Light.LIGHT_TYPE_KEYBOARD_MIC_MUTE, or android.hardware.lights.Light.LIGHT_TYPE_KEYBOARD_VOLUME_MUTE | 
          
hasBrightnessControl
fun hasBrightnessControl(): Boolean
Check whether the light has led brightness control.
| Return | |
|---|---|
Boolean | 
            True if the hardware can control the led brightness, otherwise false. | 
hasRgbControl
fun hasRgbControl(): Boolean
Check whether the light has RGB led control.
| Return | |
|---|---|
Boolean | 
            True if the hardware can control the RGB led, otherwise false. | 
toString
fun toString(): String
| Return | |
|---|---|
String | 
            a string representation of the object. | 
writeToParcel
fun writeToParcel(
dest: Parcel,
flags: Int
): Unit
Implement the Parcelable interface
| Parameters | |
|---|---|
dest | 
            Parcel: This value cannot be null. | 
          
flags | 
            Int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
