如何在ViewModel中从图库中选择照片

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

fun getPhotosFromGallery(context: Context): List<Uri> {
    val photos = mutableListOf<Uri>()
    val projection = arrayOf(MediaStore.Images.Media._ID)
    val sortOrder = "${MediaStore.Images.Media.DATE_ADDED} DESC"
    val selection = "${MediaStore.Images.Media.MIME_TYPE} = ?"
    val selectionArgs = arrayOf("image/jpeg", "image/png")

    val cursor = context.contentResolver.query(
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
        projection,
        selection,
        selectionArgs,
        sortOrder
    )

    cursor?.use {
        val idColumn = it.getColumnIndexOrThrow(MediaStore.Images.Media._ID)
        while (it.moveToNext()) {
            val id = it.getLong(idColumn)
            val contentUri = ContentUris.withAppendedId(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                id
            )
            photos.add(contentUri)
        }
    }

    return photos
}

val viewModel = ViewModelProvider(this).get(MyViewModel::class.java)

val photos = viewModel.getPhotosFromGallery(requireContext())
