                val parentPath = DCIMUtil.getDCIMPath(context)

                val fileName = System.currentTimeMillis().toString()+".png"
                val filePath = parentPath+fileName
                DCIMUtil.copyFile(file.path,filePath)
                val isSave = DCIMUtil.insertMediaPic(context,filePath)
                withContext(Dispatchers.Main) {
                    if (isSave) {
                        ToastUtils.showCenter("图片已保存到相册")
                    }else{
                        ToastUtils.showCenter("图片保存失败")
                    }
                    hideDialog()
                    dismiss()
                }
