直接贴代码：

public class GetLocalIpAddress extends Activity implements OnClickListener {

    private TextView iplocal;
    private Button click;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.acy_showipaddress);
        init();
    }

    public void init() {
        iplocal = (TextView) findViewById(R.id.tv_ipaddress);
        click = (Button) findViewById(R.id.btn_click);
        click.setOnClickListener(this);
    }

    public String GetIp() {
        try {

            for (Enumeration<NetworkInterface> en = NetworkInterface

            .getNetworkInterfaces(); en.hasMoreElements();) {

                NetworkInterface intf = en.nextElement();

                for (Enumeration<InetAddress> ipAddr = intf.getInetAddresses(); ipAddr

                .hasMoreElements();) {

                    InetAddress inetAddress = ipAddr.nextElement();
                    // ipv4地址
                    if (!inetAddress.isLoopbackAddress()
                            && InetAddressUtils.isIPv4Address(inetAddress
                                    .getHostAddress())) {

                        return inetAddress.getHostAddress();

                    }

                }

            }

        } catch (Exception ex) {

        }

        return "";

    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if (v == click) {
            iplocal.setText(GetIp().toString());
        }
    }
}

界面是添加的一个button和textview ，就不给xml了。

注意：

1.获取的地址分ipv4和ipv6地址，你需要加个判断获取ipv4的地址。
