Android xutil上传下载文件

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

2.在AndroidManifest.xml下加入权限

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() {
      @Override
      public void onFailure(HttpException arg0, String arg1) {
         result = " ";
         showInfo("上传失败");
      }

      @Override
      public void onSuccess(ResponseInfo arg0) {
         try {
            List uploadimageList = (ArrayList) 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() {
                            //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();
}
