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", "test@tsz.net");

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

带进度条的文件下载：
