android用代码怎么设置ip

本文实例讲述了Android实现编程修改手机静态IP的方法。分享给大家供大家参考。具体如下：

这里演示通过编程方式动态修改手机静态IP的方法，可以用于wifi接入点切换

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState)

setContentView(R.layout.main)

ContentResolver cr = this.getContentResolver()

try {

if (Settings.System.getInt(cr, Settings.System.WIFI_USE_STATIC_IP)==0){

Log.d("Demo", "No use Static IP!")

}

else{

Log.d("Demo", "use Static IP and Change IP to 192.168.1.123!")

Settings.System.putString(cr, Settings.System.WIFI_STATIC_IP, "192.168.1.125")

Settings.System.putString(cr, Settings.System.WIFI_STATIC_GATEWAY, "192.168.1.1")

Settings.System.putString(cr, Settings.System.WIFI_STATIC_NETMASK, "255.255.255.0")

Settings.System.putString(cr, Settings.System.WIFI_STATIC_DNS1, "202.103.24.68")

Settings.System.putString(cr, Settings.System.WIFI_STATIC_DNS2, "202.103.0.68")

}

} catch (SettingNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace()

}

}

只需将IP设置改为“静态”，然后将IP地址设置为内网的地址，网关设置为路由器地址，域名设置为DNS地址，网络前缀长度为“24”，保存就可以了。

首先需要设置权限

<uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>

设置的代码如下：

import android.provider.Settings

Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_USE_STATIC_IP, "0")

Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_DNS1, "192.168.0.2")

Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_DNS2, "192.168.0.3")

Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_GATEWAY, "192.168.0.1")

Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_NETMASK, "255.255.255.0")

Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_IP, "1")

读取配置的代码如下：

String statdns1 = android.provider.Settings.System.WIFI_STATIC_DNS1

String statdns2 = android.provider.Settings.System.WIFI_STATIC_DNS2

String sgateway = android.provider.Settings.System.WIFI_STATIC_GATEWAY

String staticip = android.provider.Settings.System.WIFI_STATIC_IP

String snetmask = android.provider.Settings.System.WIFI_STATIC_NETMASK

String staticus = android.provider.Settings.System.WIFI_USE_STATIC_IP
