                        output?.flush()
                    }
                }
            } else {
                FileOutputStream(saveFile).use {
                    if (bitmap.compress(Bitmap.CompressFormat.JPEG, 90, it)) {
                        it.flush()
                    }
                }
            }
            // android Q也可以用這個方法掃描圖片
            MediaScannerConnection.scanFile(
                context,
                arrayOf(saveFile.absolutePath),
                arrayOf("image/jpeg")
            ) { _, _ ->
            }
            // 保存成功
        } catch (e: Exception) {
            // 出錯
        }

最后通知系統(tǒng)掃描圖片的方法AndroidQ也有效, 傳入圖片絕對路徑就可以
