简单的一个函数实现对wifi设置静态或动态IP地址。
一、需要的权限
可以删除该WiFi 和修改。
二、清单文件需要将shareduserid设置成system。
android:sharedUserId="android.uid.system"三、具体函数，函数执行条件是wifi开关打开，并且要设置的wifi已经连接成功。
// 定义几种加密方式，一种是WEP，一种是WPA，还有没有密码的情况 public enum WifiCipherType { WIFICIPHER_WEP, WIFICIPHER_WPA, WIFICIPHER_NOPASS, WIFICIPHER_INVALID } /** * @param context use Application context is better * @param ipAddress ip address: like 192.168.1.168 * @param mode : STATIC or DHCP, set static or dhcp ip mode * @param netmask ip mask, like 255.255.255.0 * @param gateway gateway, like 192.168.1.1 * @param dns1 dns 1 * @param dns2 dns 2, if mode=static, then can use "" or null * @param ssid current has connected wifi ssid * @param pwd current has connected wifi pwd * @param wifiCipherType current has connected wifi capabilities * eg. dhcp mode: setWifiStaticIP(ApplicationContext, "DHCP", "", "", "", "", "", "test", "123456", WifiCipherType.WIFICIPHER_WPA);
