Android httpclient接收xml乱码问题解决方法

 

因为字符编码的问题，害我折腾了两个小时。以下是代码，大家看一下就明白了。

String url = "http://www.google.com/ig/api?weather=,,,31174165,121433841"; DefaultHttpClient client = new DefaultHttpClient();HttpUriRequest req = new HttpGet(url);HttpResponse resp = client.execute(req);HttpEntity ent = resp.getEntity();int status = resp.getStatusLine().getStatusCode();if(L.Debug) {L.d("" + status);}// 若状态码为 200 ，则表示OKif (status == HttpStatus.SC_OK) {//String result = EntityUtils.toString(ent);if(L.Debug) {//L.d(result);}InputStream stream = ent.getContent();BufferedReader br = new BufferedReader(new InputStreamReader(stream, "utf-8"));DocumentBuilder b = DocumentBuilderFactory.newInstance().newDocumentBuilder();String xmlString = "";for(String temp = br.readLine(); temp != null;xmlString += temp ,temp = br.readLine());// 去除字符串中的换行符，制表符，回车符。xmlString = xmlString.replaceAll("/n|/t|/r", "");InputStream stream2 = new ByteArrayInputStream(xmlString.getBytes());Document d = b.parse(new InputSource(stream2));NodeList n = d.getElementsByTagName("forecast_conditions");String tips = "";tips += n.item(0).getChildNodes().item(0).getAttributes().item(0).getNodeValue();if(L.Debug) {L.d("" + tips );L.d("" + n.item(0).getChildNodes().getLength());//L.Toast(tips, this);}br.close();stream.close();stream2.close();} 

关键是这一行代码

BufferedReader br = new BufferedReader(new InputStreamReader(stream, "utf-8")); 

将接收的流放入buffer里，处理成utf-8的编码（如果还是乱码，那请改为gb2312或者gbk）

 

方法二

 

String url = "http://www.google.com/ig/api?weather=,,,31174165,121433841"; DefaultHttpClient client = new DefaultHttpClient();HttpUriRequest req = new HttpGet(url);HttpResponse resp = client.execute(req);HttpEntity ent = resp.getEntity();int status = resp.getStatusLine().getStatusCode();// If the status is equal to 200 ，that is OKif (status == HttpStatus.SC_OK) {String result = EntityUtils.toString(ent);if(L.Debug) {L.testCharset(result);}// Encode utf-8 to iso-8859-1result = new String(result.getBytes("ISO-8859-1"), "UTF-8");DocumentBuilder b = DocumentBuilderFactory.newInstance().newDocumentBuilder();String xmlString = result;// Remove the newline,tabs and return characters from stringxmlString = xmlString.replaceAll("/n|/t|/r", "");InputStream stream = new ByteArrayInputStream(xmlString.getBytes());Document d = b.parse(new InputSource(stream));getWeatherBean(d);stream.close();} 

 

// 以下是测试字符编码的public static void testCharset(String datastr){ try { String temp = new String(datastr.getBytes(), "GBK"); Log.v("TestCharset","****** getBytes() -> GBK ******/n"+temp); temp = new String(datastr.getBytes("GBK"), "UTF-8"); Log.v("TestCharset","****** GBK -> UTF-8 *******/n"+temp); temp = new String(datastr.getBytes("GBK"), "ISO-8859-1"); Log.v("TestCharset","****** GBK -> ISO-8859-1 *******/n"+temp); temp = new String(datastr.getBytes("ISO-8859-1"), "UTF-8"); Log.v("TestCharset","****** ISO-8859-1 -> UTF-8 *******/n"+temp); temp = new String(datastr.getBytes("ISO-8859-1"), "GBK"); Log.v("TestCharset","****** ISO-8859-1 -> GBK *******/n"+temp); temp = new String(datastr.getBytes("UTF-8"), "GBK"); Log.v("TestCharset","****** UTF-8 -> GBK *******/n"+temp); temp = new String(datastr.getBytes("UTF-8"), "ISO-8859-1"); Log.v("TestCharset","****** UTF-8 -> ISO-8859-1 *******/n"+temp); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } } 

 

先用testCharset这个方法，测试哪一种编码没有出现乱码，再修改result = new String(result.getBytes("ISO-8859-1"), "UTF-8");里面对应的编码。
