利用FinalHttp下载上传文件

类库下载地址：类库地址

下载：

以前分享过一个文件下载的工具类，不过那个很原始对于很多场景下运用不够方便，这次我分享一个专门用来下载文件的。

很简单就一段代码：

FinalHttp finalHttp = new FinalHttp();            finalHttp.download(getString(R.string.interface_url_file) + imgBean.getTxt(), Constant.FILE_TEMP_PATH + imgBean.getId(),                    new AjaxCallBack<File>() {                        @Override                        public void onSuccess(File file) {                            super.onSuccess(file);                            DialogUtils.closeProgressDia();                                fileList.add(Constant.FILE_TEMP_PATH + imgBean.getId());                                fileHlv.setVisibility(View.VISIBLE);                                fileAdapter.notifyDataSetChanged();                        }                        @Override                        public void onFailure(Throwable t, int errorNo, String strMsg) {                            super.onFailure(t, errorNo, strMsg);                            DialogUtils.closeProgressDia();                        }                    });

download方法参数：

第一个就是文件路径url，第二个参数是本地全路径，第三个是回调方法，回调的方法可以自己根据需求选择，也可以重写progress方法实现下载监听用来添加下载进度条。

上传：

AjaxParams params = new AjaxParams(); 

params.put("username", "michael yang"); 

params.put("password", "123456"); 

params.put("email", "[e-mail]"); 

params.put("profile_picture", new File("/mnt/sdcard/pic.jpg")); // 上传文件

 params.put("profile_picture2", inputStream); // 上传数据流

 params.put("profile_picture3", new ByteArrayInputStream(bytes)); // 提交字节流 

FinalHttp fh = new FinalHttp(); 

fh.post("http://www.yangfuhai.com", params, new AjaxCallBack(){ @Override public void onLoading(long count, long current) { textView.setText(current+"/"+count); }

 @Override public void onSuccess(String t) { 

textView.setText(t==null?"null":t);

 } });

主要就是利用post上传其中AjaxParams就是参数对象类型可以是Map<String,String> 也可以是Map<String,File>等
