这个工具类我弃坑了，弃坑原因有两个
1、startActivityForResult即将方法过期
2、选择图片和调用相机，官方新api:registerForActivityResult()都有相应简单的方法，而裁剪图片需要跨app文件操作，android11之后app间文件操作需要先把文件复制到共享目录下，文件操作过于频繁且不友好，建议使用第三方裁剪库
从android10开始，我们无法直接使用外部文件，因此所有外部文件都需要使用匿名uri进行操作
获取到uri之后，如果想转换成file，可以参考：https://blog.csdn.net/jingzz1/article/details/106188462
兼容android4.0-android11
使用前，PhotoUtils.authorities 一定要改成你自己的authorities (什么是authorities)
kotlin使用方法：
由于是调用系统功能，因此不需权限
//调用相机拍照
PhotoUtils.camera(activity){
uri, success, msg ->
//uri返回的图片 success是否成功 msg错误信息
if(success)
Glide.with(this).load(uri).into(binding.ivImage)
}
//调用相册
PhotoUtils.select(activity){
uri, success, msg ->
if(success)
Glide.with(this).load(uri).into(binding.ivImage)
}
//裁剪图片
PhotoUtils.crop(fragment).apply {
setAspect(1,1)//设置裁剪比例
setOutput(300,300)//设置输出大小
}.build(uri){cropUri, success, msg ->
if(success)
Glide.with(this).load(cropUri).into(binding.ivImage)
}java使用方法：
//从相册中选择
PhotoUtils.select(activity, new Function3<Uri, Boolean, String, Unit>() {
@Override
public Unit invoke(Uri uri, Boolean success, String msg) {
return null;
}
});
//调用系统相机
PhotoUtils.camera(activity,new Function3<Uri, Boolean, String, Unit>() {
@Override
public Unit invoke(Uri uri, Boolean success, String msg) {
return null;
}
});
//裁剪图片
PhotoUtils.crop(activity)
.build(uri,new Function3<Uri, Boolean, String, Unit>() {
@Override
public Unit invoke(Uri uri, Boolean success, String msg) {
return null;
}
