Android图像选择之 PictureSelector

一款针对Android平台下的图片选择器，支持从相册获取图片、视频、音频&拍照，支持裁剪(单图or多图裁剪)、压缩、主题自定义配置等功能，支持动态获取权限&适配Android 5.0+系统的开源图片选择框架。

废话不多。开干！！

添加依赖：

    //图片选择器    api 'io.GitHub.lucksiege:pictureselector:v3.11.1'    //图片压缩    api 'io.github.lucksiege:compress:v3.11.1'    //图片裁剪    api 'io.github.lucksiege:ucrop:v3.11.1'    //自定义相机    api 'io.github.lucksiege:camerax:v3.11.1'

使用：

使用摄像头拍照：

PictureUtils.openCamera(requireActivity(), false) {val localMedia = it[0]               }

选择单张图片

  PictureUtils.createImageMin(this, ArrayList()) {val localMedia = it[0]              }

选择多张图片

PictureUtils.createImageMax(this, 9, arrayListOf()) { result: ArrayList<LocalMedia> ->   ...                         }

简单使用如上。
