Sequenceable

直接已知子类:

CdmaSignalInformation, GsmSignalInformation, LteSignalInformation, NrSignalInformation, TdscdmaSignalInformation, WcdmaSignalInformation

public abstract class SignalInformation
extends Object
implements Sequenceable

An abstract parent class that obtains signal information.

Based on the network types defined by getNetworkType(), which are GSM, CDMA, WCDMA, TD-SCDMA, LTE, and NR, the parent class contains the following child classes, which inherit from the parent class:

• GsmSignalInformation
• CdmaSignalInformation
• WcdmaSignalInformation
• TdscdmaSignalInformation
• LteSignalInformation
• NrSignalInformation

方法详细资料

getNetworkType

public int getNetworkType()

Obtains the network type of the current signal.

An application can call this method to determine the network type that the child class uses.

返回:

Returns the network type corresponding to the signal.

• TelephonyConstants#NETWORK_TYPE_UNKNOWN
• TelephonyConstants#NETWORK_TYPE_GSM
• TelephonyConstants#NETWORK_TYPE_CDMA
• TelephonyConstants#NETWORK_TYPE_WCDMA
• TelephonyConstants#NETWORK_TYPE_TDSCDMA
• TelephonyConstants#NETWORK_TYPE_LTE
• TelephonyConstants#NETWORK_TYPE_NR

getSignalLevel

public abstract int getSignalLevel()

Obtains the signal level of the current network.

This is an abstract method of the parent class whose implementation varies in child classes.

返回:

Returns an integer indicating the signal level.

hashCode

public int hashCode()

Obtains the object's hash code, which is used as an index value to search for objects in Hashtable and HashMap.

覆盖:

hashCode 在类中 Object

返回:

Returns the hash code.

equals

public boolean equals(Object other)

Checks whether the values of each member in the two objects are the same.

覆盖:

equals 在类中 Object

参数:

other - Indicates the reference object with which to compare.

返回:

Returns true if the values of each member in the two objects are the same; returns false otherwise.

marshalling

public boolean marshalling(Parcel dest)

Packs all the members in the class into a parcel object.

指定者:

marshalling 在接口中 Sequenceable

参数:

dest - Indicates the target parcel into which the members are packed.

返回:

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

unmarshalling

public boolean unmarshalling(Parcel in)

Unpacks all the members of the class from a parcel object.

指定者:

unmarshalling 在接口中 Sequenceable

参数:

in - Indicates the parcel object to be unpacked.

返回:

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