修改以太网ip的方法

今天说下修改以太网ip的方法，方便大家也方便自己以后查询。关键代码

ConnectivityManager mService = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

EthernetManager mEthManager = (EthernetManager) getSystemService(Context.ETHERNET_SERVICE);

if(mEthManager.getState() == EthernetManager.ETHERNET_STATE_ENABLED) {

EthernetDevInfo mInterfaceInfo = mEthManager.getSavedConfig();

String mIp;

String mMask;

String mGw;

String mDns;

mIp = "192.168.0.118";

mMask = "255.255.255.0";

mGw = "192.168.0.1";

mDns = "192.168.0.1";

mInterfaceInfo.setConnectMode(EthernetDevInfo.ETHERNET_CONN_MODE_MANUAL);

mInterfaceInfo.setIpAddress(mIp);

mInterfaceInfo.setNetMask(mMask);

mInterfaceInfo.setDnsAddr(mDns);

mInterfaceInfo.setGateWay(mGw);

try{

mEthManager.updateDevInfo(mInterfaceInfo);

Thread.sleep(500);

}catch(Exception e){

e.printStackTrace();

}

} else {

Toast.makeText(this, "Ethernet state disabled!", 5000).show();

}

测试随便写的，已经验证。大家根据需要自己改吧。（需要源码环境编译）
