推荐答案

您可以通过程序更改系统设置。

You can change system settings programatically.

首先，你需要请求WRITE_SETTINGS的许可在你的的Andr​​oidManifest.xml：

First you need to request the 'WRITE_SETTINGS' permission in your 'AndroidManifest.xml':

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

然后，你需要使用下面的code真正改变设置：

Then you need to actually change the setting using the following code:

    android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_USE_STATIC_IP, "0");
    android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_DNS1, "192.168.0.2");
    android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_DNS2, "192.168.0.3");
    android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_GATEWAY, "192.168.0.1");
    android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_NETMASK, "255.255.255.0");
    android.provider.Settings.System.putString(getContentResolver(), android.provider.Settings.System.WIFI_STATIC_IP, "1");

目前的设置可以通过相同的方法来访问，但使用'的getString'，而不是'putString。

The current settings can be accessed via the same method but use 'getString' instead of 'putString'.
