MediaStore.Images.保存图片时生成两张图片的问题 并且在oppo手机上时间是1970-01-01 08:00:00

正确方式如下

使用方式一

        private void saveImage(String originFilePath) {
   
            File appDir =
                    new File(Environment.getExternalStorageDirectory().getPath() + "/leikebaijing/images");
            if (!appDir.exists()) appDir.mkdirs();
            String fileName;
            long dateTaken = System.currentTimeMillis();
            if (originFilePath.contains("/")) {
   
                fileName = originFilePath.substring(originFilePath.lastIndexOf("/") + 1);
            } else {
   
                fileName = dateTaken + "jpg";
            }
            File file = new File(appDir, fileName);
            if (!file.exists()) {
   
                try {
   
                    file.createNewFile();
                } catch (IOException e) {
   
                    e.printStackTrace();
                }
            }
            if (file.exists()) {
   
                MediaStoreLocal.insertImage(getContentResolver(), ImageUtil.getBitmapFormPath(file.getAbsolutePath()), fileName, null);
                Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
                Uri uri = Uri.fromFile(file);
                intent.setData(uri);
                sendBroadcast(intent);
                ToastUtil.toastShortMessage("图片已保存");
            } else {
   
                ToastUtil.toastShortMessage("图片已过期或不存在");
            }
        }

使用方式二 kotlin语言

  
    /**
     * 保存图片到图库
     */
    private fun saveImageToGallery(context: Context, bmp: Bitmap) {
   
        // 首先保存图片
        var appDir = File(
            Environment.getExternalStorageDirectory(),
            "myqr"
        )
        if (!appDir.exists()) {
   
            appDir.mkdir()
        }
        val fileName = System.currentTimeMillis().toString() + ".jpg"
        val file = File(appDir, fileName)
//        try {
   
//            val fos = FileOutputStream(file)
//            bmp.compress(Bitmap.CompressFormat.JPEG, 100, fos)
//            fos.flush()
//            fos.close()
//        } catch (e: FileNotFoundException) {
   
//            e.printStackTrace()
//        } catch (e: IOException) {
   
//            e.printStackTrace()
//        }
        MediaStoreLocal.insertImage(context.getContentResolver(), bmp, fileName, null)
        val intent = Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE)
        val uri: Uri = Uri.fromFile(file)
        intent.setData(uri)
        context.sendBroadcast(intent)

        Toast.makeText(context, "保存成功", Toast.LENGTH_SHORT).show()
    }
