1.在build.gradle下加入compile 'org.xutils:xutils:3.5.0'

2.在AndroidManifest.xml下加入权限

<uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

3.在Application文件按的oncreate方法下加入：

x.Ext.init(this);
     //x.Ext.setDebug(BuildConfig.DEBUG); // 是否输出debug日志, 开启debug会影响性能.

4.上传图片：

public void uploadPhoto(String filePath, String url) {
    
       HttpUtils httpUtils = new HttpUtils(30000);
       RequestParams params = new RequestParams();
       params.addBodyParameter("file", new File(filePath));
        //以post的方式上传图片
       httpUtils.send(HttpMethod.POST, url, params, new RequestCallBack<String>() {
          @Override
          public void onFailure(HttpException arg0, String arg1) {
             result = " ";
             showInfo("上传失败");
          }
    
          @Override
          public void onSuccess(ResponseInfo<String> arg0) {
             try {
                List<UploadImage> uploadimageList = (ArrayList<UploadImage>) JsonUitl.stringToList(arg0.result, UploadImage.class);
                if (uploadimageList.size() > 0) {
                   result = uploadimageList.get(0).getUrl();
                }
             } catch (Exception r) {
                String s = r.getMessage();
             }
          }
    
       });
    
    }

5 .下载图片

ExecutorService executorService = Executors.newCachedThreadPool();

try {
        JSONArray jsonArray=new JSONArray(result);
        if(jsonArray.length()>0){
            for(int i=0;i<jsonArray.length();i++) {
                final JSONObject jsonObject = (JSONObject) jsonArray.get(i);
                executorService.execute(new Runnable() {
                    @Override
                    public void run() {
                        try {
                             //图片的请求路径
                            RequestParams requestParams = new RequestParams("http://**************/"+jsonObject.getString("resourceAddress"));
                           //图片保存在本地路径                 requestParams.setSaveFilePath("/sdcard/tudou/"+jsonObject.getString("resourceAddress"));
                            x.http().get(requestParams, new Callback.ProgressCallback<File>() {
                                //等待时回调方法
                                @Override
                                public void onWaiting() {
                                   
                                }
                                //开始后回调方法
                                @Override
                                public void onStarted() {
    
                                }
                                //加载时回调方法
                                @Override
                                public void onLoading(long total, long current, boolean isDownloading) {
    
                                }
                                //下载成功的回调方法
                                @Override
                                public void onSuccess(File result) {
                                     
                                }
                                //出错时回调方法
                                @Override
                                public void onError(Throwable ex, boolean isOnCallback) {
    
                                }
                                //取消时回调方法
                                @Override
                                public void onCancelled(CancelledException cex) {
    
                                }  
                                //完成时回调方法
                                @Override
                                public void onFinished() {
    
                                }
                            });
    
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                });
    
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
