Android获取热点主机ip和连接热点手机ip的代码

其中定义WIFI AP的几个状态

public static final int WIFI_AP_STATE_DISABLING = 10;  
public static final int WIFI_AP_STATE_DISABLED = 11;  
public static final int WIFI_AP_STATE_ENABLING = 12;  
public static final int WIFI_AP_STATE_ENABLED = 13;  
public static final int WIFI_AP_STATE_FAILED = 14;

对应于WifiMangaer.java中对这几个状态的定义。

获取WIFI热点的状态：

public int getWifiApState(Context mContext) {  
 WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);  
   try {  
     Method method = wifiManager.getClass().getMethod("getWifiApState");  
     int i = (Integer) method.invoke(wifiManager);  
     Log.i(TAG,"wifi state: " + i);  
     return i;  
   } catch (Exception e) {  
     Log.e(TAG,"Cannot get WiFi AP state" + e);  
     return WIFI_AP_STATE_FAILED;  
   }  
 }

判断Wifi热点是否可用：

private ArrayList<String> getConnectedHotIP() {
 ArrayList<String> connectedIP = new ArrayList<String>();
 try {
   BufferedReader br = new BufferedReader(new FileReader(
       "/proc/net/arp"));
   String line;
   while ((line = br.readLine()) != null) {
     String[] splitted = line.split(" +");
     if (splitted != null && splitted.length >= 4) {
       String ip = splitted[0];
       connectedIP.add(ip);
     }
   }
 } catch (Exception e) {
   e.printStackTrace();
 }
 return connectedIP;
}
//输出链接到当前设备的IP地址
public void printHotIp() {

ArrayList<String> connectedIP = getConnectedHotIP();
 StringBuilder resultList = new StringBuilder();
 for (String ip : connectedIP) {
   resultList.append(ip);
   resultList.append("\n");
 }
 System.out.print(resultList);
 Log.d(TAG,"---->>heww resultList="+resultList);
}

当然在应用中要添加访问WIFI设备的权限：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

获取热点主机ip地址的代码：

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
     DhcpInfo info=wifiManager.getDhcpInfo();
     System.out.println(info.serverAddress);

总结
