枚举常量概要

枚举常量

枚举常量	说明
IDLE	Indicates the idle state where no call exists and the device does not ring.
IN_CALL	Indicates the calling state where a call is set up.
IN_VOIP	Indicates the communication state where an audio or video chat or VoIP call is set up.
RINGTONE	Indicates the ringing state where a calling signal is received.

方法概要

限定符和类型	方法	说明
static AudioManager.CallState	getEnumByValue(int value)	Obtains an enum name based on the value.
int	getValue()	Obtains an enum value.
static AudioManager.CallState	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 AudioManager.CallState[]	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 (AudioManager.CallState c : AudioManager.CallState.values()) System.out.println(c);
