CREATOR

Added in API level 23
Creator<CallAudioState> CREATOR

负责为反序列化Parcels创建AudioState对象。

Public constructors

CallAudioState

Added in API level 23
CallAudioState (boolean muted, 
                int route, 
                int supportedRouteMask)

CallAudioState对象的 CallAudioState函数。

Parameters
muted boolean: true if the call is muted, false otherwise.
route int: The current audio route being used. Allowed values: ROUTE_EARPIECE ROUTE_BLUETOOTH ROUTE_WIRED_HEADSET ROUTE_SPEAKER
supportedRouteMask int: Bit mask of all routes supported by this call. This should be a bitwise combination of the following values: ROUTE_EARPIECE ROUTE_BLUETOOTH ROUTE_WIRED_HEADSET ROUTE_SPEAKER

Public methods

audioRouteToString

Added in API level 23
String audioRouteToString (int route)

将提供的音频路由转换为可读的字符串表示形式。

Parameters
route int: to convert into a string.
Returns
String String representation of the provided audio route.

describeContents

Added in API level 23
int describeContents ()

描述此Parcelable实例的封送表示中包含的特殊对象的种类。 例如,如果对象将在writeToParcel(Parcel, int)的输出中包含writeToParcel(Parcel, int) ,则此方法的返回值必须包含CONTENTS_FILE_DESCRIPTOR位。

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

equals

Added in API level 23
boolean equals (Object obj)

指示其他某个对象是否“等于”这一个。

equals方法在非空对象引用上实现等价关系:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

Objectequals方法实现了对象上最可能的等价关系; 也就是说,对于任何非空参考值xy ,当且仅当xy指向同一对象( x == y的值为true )时,此方法返回true

请注意,无论何时重写此方法,通常都需要重写 hashCode方法,以维护 hashCode方法的常规协定,该方法声明等同对象必须具有相同的哈希码。

Parameters
obj Object: the reference object with which to compare.
Returns
boolean true if this object is the same as the obj argument; false otherwise.

getRoute

Added in API level 23
int getRoute ()

Returns
int The current audio route being used.

getSupportedRouteMask

Added in API level 23
int getSupportedRouteMask ()

Returns
int Bit mask of all routes supported by this call.

isMuted

Added in API level 23
boolean isMuted ()

Returns
boolean true if the call is muted, false otherwise.

toString

Added in API level 23
String toString ()

返回对象的字符串表示形式。 通常, toString方法返回一个“文本表示”该对象的字符串。 结果应该是一个简洁但内容丰富的表述,对于一个人来说很容易阅读。 建议所有子类重写此方法。

ObjecttoString方法返回一个字符串,其中包含对象为实例的类的名称,符号字符“ @ ”以及对象的哈希代码的无符号十六进制表示形式。 换句话说,这个方法返回一个字符串,其值等于:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

writeToParcel

Added in API level 23
void writeToParcel (Parcel destination, 
                int flags)

将AudioState对象写入可序列化的Parcel。

Parameters
destination Parcel: The Parcel in which the object should be written.
flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.

Hooray!
