MediaStore.Images.ImageColumns.DATA 弃用后如何使用 MediaStore 从特定文件夹中获取图像数据

如何解决MediaStore.Images.ImageColumns.DATA 弃用后如何使用 MediaStore 从特定文件夹中获取图像数据

我正在尝试将图像发布到特定文件夹中。我已经成功地做到了这一点。但为了获取数据，我一直在使用 MediaStore.Images.ImageColumns.DATA 已弃用且因此我想使用更新的方法来检索信息。

我使用以下代码保存了图像并且完全正常

suspend fun saveImage(context: Context,bitmap: Bitmap) {
        withContext(Dispatchers.IO) {
            val collection =
                MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
            val dirDest = File(
                Environment.DIRECTORY_PICTURES,context.getString(R.string.app_name) + File.separator + CAMERA
            )
            val filePath = dirDest.absolutePath
            val date = System.currentTimeMillis()

            val newImage = ContentValues().apply {
                put(MediaStore.Images.Media.DISPLAY_NAME,"$date.$IMAGE_EXTENSIONS")
                put(MediaStore.MediaColumns.MIME_TYPE,"image/$IMAGE_EXTENSIONS")
                put(MediaStore.MediaColumns.DATE_ADDED,date)
                put(MediaStore.MediaColumns.DATE_MODIFIED,date)
                put(MediaStore.MediaColumns.SIZE,bitmap.byteCount)
                put(MediaStore.MediaColumns.WIDTH,bitmap.width)
                put(MediaStore.MediaColumns.HEIGHT,bitmap.height)
                put(MediaStore.MediaColumns.RELATIVE_PATH,"$dirDest${File.separator}")
                put(MediaStore.Images.Media.IS_PENDING,1)
            }


            val newImageUri = context.contentResolver.insert(collection,newImage)

            context.contentResolver.openOutputStream(newImageUri!!,"w").use {
                bitmap.compress(Bitmap.CompressFormat.JPEG,100,it)
            }

            newImage.clear()
            newImage.put(MediaStore.Images.Media.IS_PENDING,0)
            context.contentResolver.update(newImageUri,newImage,null,null)
        }
    }

问题在于检索信息时。 我使用的代码如下：

  private fun getData() {
        lifecycleScope.launch(Dispatchers.IO) {
            val collection = sdk29AndUp {
                MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL)
            } ?: MediaStore.Images.Media.EXTERNAL_CONTENT_URI


            val file = File(
                Environment.DIRECTORY_PICTURES,requireContext().getString(R.string.app_name) + File.separator + CAMERA
            )


            val filePath = file.absolutePath

           val selection = MediaStore.Images.ImageColumns.DATA + " like '%" + filePath + "%'"

            val projection = arrayOf(
                MediaStore.Images.Media._ID,MediaStore.Images.Media.DISPLAY_NAME
            )
            val photoList = mutableListOf<SharedStoragePhoto>()

            contentResolver?.query(
                collection,projection,selection,null
            )?.use { cursor ->

                val idColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID)
                val displayNameColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DISPLAY_NAME)
                while (cursor.moveToNext()) {
                    val id = cursor.getLong(idColumn)
                    val displayName = cursor.getString(displayNameColumn)

                    photoList.add(SharedStoragePhoto(id,displayName))

                }

            }
           
        }
    }

由于不推荐使用 MediaStore.Images.ImageColumns.DATA，请提出解决方法。 提前致谢

解决方法

正如@blackapps 所回答的那样。这是使用RELATIVE_PATH解决问题的方法

    private fun getData() {

        lifecycleScope.launch(Dispatchers.IO) {
            val collection = sdk29AndUp {
                MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL)
            } ?: MediaStore.Images.Media.EXTERNAL_CONTENT_URI

            val selection =
                MediaStore.Images.ImageColumns.RELATIVE_PATH + " like '%" + CAMERA + "%'"
            val projection = arrayOf(
                MediaStore.Images.Media._ID,MediaStore.Images.Media.DISPLAY_NAME,MediaStore.Images.Media.RELATIVE_PATH
            )
            contentResolver?.query(
                collection,projection,selection,null,null
            )?.use { cursor ->

                val idColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID)
                val displayNameColumn =
                    cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DISPLAY_NAME)
                val relativePathColumn =
                    cursor.getColumnIndexOrThrow(MediaStore.Images.Media.RELATIVE_PATH)
                while (cursor.moveToNext()) {
                    val id = cursor.getLong(idColumn)
                    val displayName = cursor.getString(displayNameColumn)
                    val relativePath = cursor.getString(relativePathColumn)

                    val contentUri = ContentUris.withAppendedId(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,id
                    )
                        )
                    }
                }

                cursor.close()
            }
        }
    }
