想要設(shè)置以太網(wǎng)為靜態(tài)IP通過搜索是需用到EthernetManager释簿，但是EthernetManager是谷歌隱藏的API，app是無法調(diào)用到的辕万，所以只能通過反射來進行設(shè)置
也可以通過下載系統(tǒng)的class.jar包沉删，放到自己的項目中，就可以不用反射矾瑰，直接調(diào)用
下邊是引入jar包直接調(diào)用的代碼，通過EthernetManager 的setConfiguration方法來設(shè)置凉夯，但是需要構(gòu)造IpConfiguration 和StaticIpConfiguration對象，IpConfiguration.IpAssignment.STATIC就代表設(shè)置為靜態(tài)IP劲够，也可以設(shè)置DHCP
private void setStaticIP() {
EthernetManager mEthManager = (EthernetManager) getSystemService("ethernet");
StaticIpConfiguration mStaticIpConfiguration = new StaticIpConfiguration();
/*
* get ip address, netmask,dns ,gw etc.
*/
Inet4Address inetAddr = getIPv4Address(mEthIpAddress);
int prefixLength = NetUtils.maskStr2InetMask(mEthNetmask);
InetAddress gatewayAddr = getIPv4Address(mEthGateway);
InetAddress dnsAddr = getIPv4Address(mEthdns1);
if (inetAddr.getAddress().toString().isEmpty() || prefixLength ==0 || gatewayAddr.toString().isEmpty()
|| dnsAddr.toString().isEmpty()) {
return;
}
Class<?> clazz = null;
try {
clazz = Class.forName("android.net.LinkAddress");
} catch (Exception e) {
// TODO: handle exception
}
Class[] cl = new Class[]{InetAddress.class, int.class};
Constructor cons = null;
//取得所有構(gòu)造函數(shù)
try {
cons = clazz.getConstructor(cl);
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
//給傳入?yún)?shù)賦初值
Object[] x = {inetAddr, prefixLength};
String dnsStr2 = mEthdns2;
//mStaticIpConfiguration.ipAddress = new LinkAddress(inetAddr, prefixLength);
try {
mStaticIpConfiguration.ipAddress = (LinkAddress) cons.newInstance(x);
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
mStaticIpConfiguration.gateway=gatewayAddr;
mStaticIpConfiguration.dnsServers.add(dnsAddr);
if (!dnsStr2.isEmpty()) {
mStaticIpConfiguration.dnsServers.add(getIPv4Address(dnsStr2));
}
Log.d("2312321", "chanson mStaticIpConfiguration ====" + mStaticIpConfiguration);
IpConfiguration mIpConfiguration = new IpConfiguration(IpConfiguration.IpAssignment.STATIC, IpConfiguration.ProxySettings.NONE, mStaticIpConfiguration, null);
mEthManager.setConfiguration(mIpConfiguration);
}
不想引用jar包的話就需要使用反射來實現(xiàn)征绎，下邊代碼是我模仿這個邏輯通過反射來實現(xiàn)的代碼

最好放到主線程中執(zhí)行江咳，因為我之前測試在子線程有報錯，所以需要切換到主線程歼指，參考文章http://www.reibang.com/p/16792c2ef112
兩種方式都可以設(shè)置成功甥雕，根據(jù)個人需要使用即可，class.jar可以通過到參考項目libs中進行下載
當(dāng)然還需要應(yīng)用有系統(tǒng)權(quán)限才可以設(shè)置犀农，所以需要改為系統(tǒng)應(yīng)用并進行系統(tǒng)簽名才可真正設(shè)置成功
