Android获取热点主机ip和连接热点手机ip的代码
作者：ChinaWallace
这篇文章主要介绍了Android获取热点主机ip和连接热点手机ip的相关资料,需要的朋友可以参考下
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);
