an框架的网络框架是完全基于Xutils3.0以上的，这里需要感谢前辈/wyouflf/xUtils3的无私奉献。

Begin

使用方法：

compile 'com.github.qydq:an-maven-base:0.0.9'

DXUtils，XProgressCallBack和XCallBack是an框架提供的辅助类。

1.得到以Xml的形式返回的数据

private void getxml() {
    String url = "http://flash.weather.com.cn/wmaps/xml/china.xml";
    DXUtils.Get(url, null, new XCallBack<String>() {
@Override
        public void onSuccess(String xmlString) {
super.onSuccess(xmlString);
            try {
                XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
                XmlPullParser xmlPullParser = factory.newPullParser();
                xmlPullParser.setInput(new StringReader(xmlString));
                int eventType = xmlPullParser.getEventType();
                while (eventType != XmlPullParser.END_DOCUMENT) {
switch (eventType) {
case XmlPullParser.START_TAG:
                            String nodeName = xmlPullParser.getName();
                            if ("city".equals(nodeName)) {
                                String pName = xmlPullParser.getAttributeValue(0);
                                Log.e("TAG", "city is " + pName);
                                showToast("city is:" + pName + "weather is");
                            }
break;
                    }
                    eventType = xmlPullParser.next();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
@Override
        public void onError(Throwable ex, boolean isOnCallback) {
super.onError(ex, isOnCallback);
        }
    });
}

2.下载带进度的文件

private void downloadprogressfile() {
//文件下载地址
    String url = "";
    //文件保存在本地的路径
    String filepath = "";
    DXUtils.DownLoadFile(url, filepath, new XProgressCallBack<File>() {
@Override
        public void onSuccess(File result) {
super.onSuccess(result);
            showToast("result:" + result.toString());
        }
@Override
        public void onError(Throwable ex, boolean isOnCallback) {
super.onError(ex, isOnCallback);
        }
    });
}

3.下载普通类型的文件

private void downloadfile() {
//文件下载地址
    String url = "";
    //文件保存在本地的路径
    String filepath = "";
    DXUtils.DownLoadFile(url, filepath, new XCallBack<File>() {
@Override
        public void onSuccess(File result) {
super.onSuccess(result);
            showToast("result:" + result.toString());
        }
@Override
        public void onError(Throwable ex, boolean isOnCallback) {
super.onError(ex, isOnCallback);
        }
    });
}

4.上传文件

/**
 * 上传文件(支持多文件上传)
 */
private void uploadfile() {
//图片上传地址
    String url = "";
    Map<String, Object> map = new HashMap<>();
    //传入自己的相应参数
    //map.put(key, value);
    //map.put(key, value);
    DXUtils.UpLoadFile(url, map, new XCallBack<String>() {
@Override
        public void onSuccess(String result) {
super.onSuccess(result);
            showToast("result:" + result);
        }
@Override
        public void onError(Throwable ex, boolean isOnCallback) {
super.onError(ex, isOnCallback);
        }
    });
}

5.an框架提供的Get请求

private void get() {
    String url = "http://api.k780.com:88/?app=idcard.get";
    Map<String, String> map = new HashMap<>();
    map.put("appkey", "10003");
    map.put("sign", "b59bc3ef6191eb9f747dd4e83c99f2a4");
    map.put("format", "json");
    map.put("idcard", "110101199001011114");
    DXUtils.Get(url, map, new XCallBack<PersonInfoBean>() {
@Override
        public void onSuccess(PersonInfoBean result) {
super.onSuccess(result);
            Log.e("result", result.toString());
            showToast("result:" + result.getResult());
        }
@Override
        public void onError(Throwable ex, boolean isOnCallback) {
super.onError(ex, isOnCallback);
        }
    });
}

6.an框架提供的Post请求

private void post() {
    String url = "http://api.k780.com:88/?app=idcard.get";
    Map<String, Object> map = new HashMap<>();
    map.put("appkey", "10003");
    map.put("sign", "b59bc3ef6191eb9f747dd4e83c99f2a4");
    map.put("format", "json");
    map.put("idcard", "110101199001011114");
    DXUtils.Post(url, map, new XCallBack<PersonInfoBean>() {
@Override
        public void onSuccess(PersonInfoBean result) {
super.onSuccess(result);
            Log.e("result", result.toString());
            showToast("result,信息:" + result.getMsgid());
        }
@Override
        public void onError(Throwable ex, boolean isOnCallback) {
super.onError(ex, isOnCallback);
        }
    });
}
End
