You can create a function that takes in a path, and by the file extension in its name, corresponds to the drawable.

fun getFileTypeIcon(path: String): Int {
    val file = File(path)
    val ext = MimeTypeMap.getFileExtensionFromUrl(file.name)
    Log.i("ImagesExt", "$path ----> $ext")
    return when (".$ext") {
        ".png", ".jpg", ".jpeg", ".gif", ".bmp" -> R.drawable.image
        ".mp3", ".wav", ".ogg", "midi" -> R.drawable.audio
        ".mp4", ".rmvb", ".avi", ".flv", ".3gp" -> R.drawable.video
        ".jsp", ".html", ".htm", ".js", ".php" -> R.drawable.web
        ".txt", ".c", ".cpp", ".xml", ".py", ".json", ".log" -> R.drawable.file
        ".xls", ".xlsx" -> R.drawable.file
        ".doc", ".docx" -> R.drawable.file
        ".ppt", ".pptx" -> R.drawable.file
        ".pdf" -> R.drawable.pdf
        ".jar", ".zip", ".rar", ".gz" -> R.drawable.zip
        ".apk" -> R.drawable.apk
        else -> R.drawable.file
    }
}
