安卓得到外部IP [英] Android get external IP

问题描述

我正在开发的Andr​​oid 2.1的应用程序，我想显示外部IP。我怎么能这样做？先谢谢了。

解决方案

 公共无效getCurrentIP（）{
    ip.setText（请稍候...）;
    尝试 {
            HttpClient的HttpClient的=新DefaultHttpClient（）;
            HTTPGET HTTPGET =新HTTPGET（http://ifcfg.me/ip）;
            // HTTPGET HTTPGET =新HTTPGET（http://ipecho.net/plain）;
            HTT presponse响应;

            响应= httpclient.execute（HTTPGET）;

            。//Log.i("externalip",response.getStatusLine（）的toString（））;

            HttpEntity实体= response.getEntity（）;
            如果（实体！= NULL）{
                    长的len = entity.getContentLength（）;
                    如果（LEN = -1放大器;！＆安培; LEN＆LT; 1024）{
                            字符串str = EntityUtils.toString（实体）;
                            //Log.i("externalip",str）;
                ip.setText（STR）;
                    } 其他 {
                            ip.setText（响应时间过长或错误。）;
                            //调试
                            //ip.setText("Response太长或错误：+ EntityUtils.toString（实体））;
                            //Log.i("externalip",EntityUtils.toString(entity））;
                    }
            } 其他 {
                    ip.setText（空：+ response.getStatusLine（）的toString（））;
            }

    }
    赶上（例外五）
    {
        ip.setText（错误）;
    }

}

解决方案

public void getCurrentIP () {
    ip.setText("Please wait...");  
    try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpGet httpget = new HttpGet("http://ifcfg.me/ip");
            // HttpGet httpget = new HttpGet("http://ipecho.net/plain");
            HttpResponse response;

            response = httpclient.execute(httpget);

            //Log.i("externalip",response.getStatusLine().toString());

            HttpEntity entity = response.getEntity();
            if (entity != null) {
                    long len = entity.getContentLength();
                    if (len != -1 && len < 1024) {
                            String str=EntityUtils.toString(entity);
                            //Log.i("externalip",str);
                ip.setText(str);
                    } else {
                            ip.setText("Response too long or error.");
                            //debug
                            //ip.setText("Response too long or error: "+EntityUtils.toString(entity));
                            //Log.i("externalip",EntityUtils.toString(entity));
                    }            
            } else {
                    ip.setText("Null:"+response.getStatusLine().toString());
            }

    }
    catch (Exception e)
    {
        ip.setText("Error");
    }

}
