android选择图片或拍照图片上传到服务器(包括上传参数)
最近要搞一个项目,需要上传相册和拍照的图片,不负所望,终于完成了! 不过需要说明一下,其实网上很多教程拍照的图片,都是缩略图不是很清晰,所以需要在调用照相机的时候,事先生成一个地址,用于标识拍照的图片URI
具体上传代码:
1.选择图片和上传界面,包括上传完成和异常的回调监听
- package com.spring.sky.image.upload;
- import java.util.HashMap;
- import java.util.Map;
- import android.app.Activity;

2.选择图片界面,主要涉及两种方式:选择图片和及时拍照图片
- package com.spring.sky.image.upload;

3. 上传工具类,主要实现了图片的上传,上传过程的初始化监听和上传完成的监听,还有上传耗时的计算
