所有已实现的接口:

Serializable, Comparable<PowerManager.PowerState>

封闭类:

PowerManager

public static enum PowerManager.PowerState
extends Enum<PowerManager.PowerState>

Indicates the power status of a device.

The status can be NONE, AWAKE, INACTIVE, or SLEEP.

枚举常量概要

枚举常量

枚举常量	说明
AWAKE	Indicates that the screen is on and the system is running.
INACTIVE	Indicates that the screen is off and the system is running.
NONE	Indicates an unknown status.
SLEEP	Indicates that the screen is off and the system is hibernating.

方法概要

限定符和类型	方法	说明
static PowerManager.PowerState	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static PowerManager.PowerState[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (PowerManager.PowerState c : PowerManager.PowerState.values()) System.out.println(c);
