方法详细资料

marshalling

public boolean marshalling(Parcel out)

Writes a Sequenceable object into a Parcel for linked info.

指定者:

marshalling 在接口中 Sequenceable

参数:

out - Indicates the Parcel object to which the Sequenceable object will be written.

返回:

Returns true if the marshalling is successful; returns false otherwise.

从以下版本开始:

1

unmarshalling

public boolean unmarshalling(Parcel in)

Restores a Sequenceable object from a Parcel for linked info.

指定者:

unmarshalling 在接口中 Sequenceable

参数:

in - Indicates the Parcel object into which the Sequenceable object has been written.

返回:

Returns true if the unmarshalling is successful; returns false otherwise.

getBssid

public String getBssid()

Obtains the BSSID of a Wi-Fi access point.

The BSSID is in XX:XX:XX:XX:XX:XX format.

If you have no permission to obtain the BSSID, 02:00:00:00:00:00 is returned.

返回:

Returns the BSSID of the Wi-Fi access point; returns null if no BSSID is found.

从以下版本开始:

1

getRssi

public int getRssi()

Obtains the RSSI of a Wi-Fi access point.

The unit of RSSI is dBm.

返回:

Returns the RSSI of the Wi-Fi access point.

从以下版本开始:

1

getFrequency

public int getFrequency()

Obtains the frequency of a Wi-Fi access point.

返回:

Returns the frequency of the Wi-Fi access point.

从以下版本开始:

getSsid

public String getSsid()

Obtains the SSID of a Wi-Fi access point.

The SSID is in UTF-8 format.

返回:

Returns the SSID of the Wi-Fi access point.

从以下版本开始:

1

getLinkSpeed

public int getLinkSpeed()

Obtains the speed of a Wi-Fi access point.

返回:

Returns the speed of the Wi-Fi access point.

从以下版本开始:

getBand

public int getBand()

Obtains the frequency band of a Wi-Fi access point.

Two types of frequency bands are available: 2.4 GHz WifiEvents#BAND_WIFI_2G and 5 GHz WifiEvents#BAND_WIFI_5G.

返回:

Returns the frequency band of the Wi-Fi access point; returns WifiEvents#BAND_INVALID if the frequency band is invalid.

从以下版本开始:

1

getMacAddress

public String getMacAddress()

isHiddenSsid

public boolean isHiddenSsid()

Checks whether the SSID of the access point (AP) of this Wi-Fi connection is hidden.

返回:

Returns true if the SSID is hidden; returns false otherwise.

从以下版本开始:

toString

public String toString()

从类复制的说明: Object

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

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

覆盖:

toString 在类中 Object

返回:

a string representation of the object.
