you can try this:

    fun renameFile(){
        var file = listDownloadsFile.get(i).file

        val oldName = file.nameWithoutExtension
        val newPath = file.path.replace(oldName, new_name).trim()
        val filetwo = File(newPath)
        if (filetwo.exists()) {
            //show a message file exited
        } else {
            val check = renameFile(file, filetwo)
            if(check){
                Log.d("kkdkdk",check.toString())
            }
            else{
                Log.d("kkdkdk",check.toString())
            }
        }
    }

    private fun rename(from: File, to: File): Boolean {
        return from.parentFile.exists() && from.exists() && from.renameTo(to)
    }
