释放双眼，带上耳机，听听看~！

今天，简单讲讲如何获取连接的WiFi的名称。

首先AndroidMainfest.xml文件中添加权限：

然后直接获取WiFi名称

WifiManager wifiMgr = (WifiManager) mActivity.getSystemService(Context.WIFI_SERVICE);

int wifiState = wifiMgr.getWifiState();

WifiInfo info = wifiMgr.getConnectionInfo();

String wifiId = info != null ? info.getSSID() : null;

这里的WiFi名称的字符串加了双引号，如果输出，自己可以去掉。

接下来讲讲如何获取WiFi连接的ip地址和判断WiFi是否连接

public static InetAddress getWifiIp() {

Context myContext = Globals.getContext();

if (myContext == null) {

throw new NullPointerException("Global context is null");

}

WifiManager wifiMgr = (WifiManager) myContext.getSystemService(Context.WIFI_SERVICE);

if (isWifiEnabled()) {

int ipAsInt = wifiMgr.getConnectionInfo().getIpAddress();

if (ipAsInt == 0) {

return null;

} else {

return Util.intToInet(ipAsInt);

}

} else {

return null;

}

}

// 取得wifi的ip地址

InetAddress address = FTPServerService.getWifiIp();

address.getHostAddress();

public static boolean isWifiEnabled() {

Context myContext = Globals.getContext();

if (myContext == null) {

throw new NullPointerException("Global context is null");

}

WifiManager wifiMgr = (WifiManager) myContext.getSystemService(Context.WIFI_SERVICE);

if (wifiMgr.getWifiState() == WifiManager.WIFI_STATE_ENABLED) {

ConnectivityManager connManager = (ConnectivityManager) myContext

.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo wifiInfo = connManager

.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

return wifiInfo.isConnected();

} else {

return false;

}

}

// 打开wifi设置的页面

Intent intent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS);

startActivity(intent);

android  获取连接WiFi的名称就讲完了。

就这么简单。
