## android.net.wifi   类 ScanResult ##

java.lang.Object
      android.net.wifi.ScanResult

所有已实现的接口：

Parcelable

--------------------

public class ScanResult
       
        extends Object
       
       
        implements Parcelable

Describes information about a detected access point. In addition to the attributes described here, the supplicant keeps track of `quality`, `noise`, and `maxbitrate`attributes, but does not currently report them to external clients.

### SSID ###

public String SSID

The network name.

--------------------

### BSSID ###

public String BSSID

The address of the access point.

--------------------

### capabilities ###

public String capabilities

Describes the authentication, key management, and encryption schemes supported by the access point.

--------------------

### level ###

public int level

The detected signal level in dBm. At least those are the units used by the TI driver.

--------------------

### frequency ###

public int frequency

The frequency in MHz of the channel over which the client is communicating with the access point.

--------------------

### CREATOR ###

public static final Parcelable.Creator<ScanResult> CREATOR

Implement the Parcelable interface

<table style="color:rgb(0,0,0); font-size:12px; line-height:20px"> 
 <tbody> 
  <tr style="background:rgb(204,204,255)"> 
   <th align="left" colspan="1"><span style=""><span style="color:rgb(51,51,51)">构造方法详细信息</span></span></th> 
  </tr> 
 </tbody> 
</table>

### ScanResult ###

public ScanResult(String SSID,
                      String BSSID,
                      String caps,
                      int level,
                      int frequency)

We'd like to obtain the following attributes, but they are not reported via the socket interface, even though they are known internally by wpa\_supplicant.

<table style="color:rgb(0,0,0); font-size:12px; line-height:20px"> 
 <tbody> 
  <tr style="background:rgb(204,204,255)"> 
   <th align="left" colspan="1"><span style=""><span style="color:rgb(51,51,51)">方法详细信息</span></span></th> 
  </tr> 
 </tbody> 
</table>

### toString ###

public String toString()

从类 `Object` 复制的描述

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation simply concatenates the class name, the '@' sign and a hexadecimal representation of the object's Object.hashCode(), that is, it is equivalent to the following expression:

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

覆盖：

类 `Object` 中的 `toString`

a printable representation of this object.

--------------------

### describeContents ###

public int describeContents()

Implement the Parcelable interface

指定者：

接口 `Parcelable` 中的 `describeContents`

a bitmask indicating the set of special object types marshalled by the Parcelable.
