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);
