枚举常量概要

枚举常量

枚举常量	说明
CONNECTED	Indicates that the device is connected.
CONNECTING	Indicates that the device is being connected.
DIS_CONNECTING	Indicates that the device is being disconnected.
FAILURE	Indicates that the device fails to be connected.
IDLE	Indicates that the device is in the initial state or is disconnected.

方法概要

限定符和类型	方法	说明
static DeviceConnectState	getConnectState(int state)	Obtains a DeviceConnectState enum constant based on a specified int value.
int	getState()	Obtains the int value representing the device connection state enumerated in DeviceConnectState.
static DeviceConnectState	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 DeviceConnectState[]	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 (DeviceConnectState c : DeviceConnectState.values()) System.out.println(c);
