编程修改手机的静态IP

通过编程方式动态修改手机的静态IP，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();

		}        

		

        

    }
