android url 中文请求,乱码解决

解决乱码的代码:

    private String connServerForResult(String url) {
        String strResult = "";
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost();
            httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
            httpPost.setURI(new URI(url));

            //httpPost,通过urlParam添加请求参数
            List<NameValuePair> urlParam = new ArrayList<NameValuePair>();

            //中文内容，通过URLDecoder.decode转码
            urlParam.add(new BasicNameValuePair("date", URLDecoder.decode(date_search.getText().toString(), "utf-8")));

            httpPost.setEntity( new UrlEncodedFormEntity(urlParam, HTTP.UTF_8));
            HttpResponse response = httpClient.execute(httpPost);
            HttpEntity entity = response.getEntity();
            if (entity != null)
                strResult = EntityUtils.toString(entity, HTTP.UTF_8);
        } catch (Exception e) {
        }
        return strResult;
    }
