如何显示从Firebase存储的下载进度.我可以下载文件,但无法显示下载进度.我怎样才能做到这一点？

这是我的简单代码,可从Firebase存储区下载.mp3文件->

    fun getSound(dSoundindex : Int) {        Toast.makeText(context.applicationContext,"Starting Downloading",Toast.LENGTH_SHORT).show()        val mStorage = FirebaseStorage.getInstance("gs://depressioncuresounds-9e9a8.appspot.com")        val mStorageRef = mStorage.reference        try {            val downloadRef = mStorageRef.root.child(downloadpath)            val rootPath = file(Environment.getExternalStorageDirectory(),"DepressionCureSounds")            if(!rootPath.exists()){                rootPath.mkdirs()            }            val localfile = file(rootPath,"sound2.mp3")            downloadRef.getfile(localfile).addOnSuccessListener {                Toast.makeText(context.applicationContext, "Sound downloaded successfully", Toast.LENGTH_LONG).show()                when(context.soundAndImagesIndex){                    5->{                        context.isSoundDownloaded[0] = true                    }                    6->{                        context.isSoundDownloaded[1] = true                    }                    7->{                        context.isSoundDownloaded[2] = true                    }                    8->{                        context.isSoundDownloaded[3] = true                    }                    9->{                        context.isSoundDownloaded[4] = true                    }                    else->{                        Toast.makeText(context.applicationContext,"BUG in Coding",Toast.LENGTH_LONG).show()                    }                }            }.addOnFailureListener { exception ->                Toast.makeText(context.applicationContext, "Failed to download file ${exception.toString()}", Toast.LENGTH_LONG).show()            }         } catch (e: IOException) {            Toast.makeText(context.applicationContext, "IOException Failed to download file", Toast.LENGTH_LONG).show()        }     }

解决方法:

使用此工具,您可以从Firebase存储下载文件,进度监听器将为您提供进度.希望能帮助到你

//Show Progress Dialog\    file localfile = file.createTempfile("audiofile", "mp3");    yourStorageReference.getfile(localfile).addOnSuccessListener(new OnSuccessListener<fileDownloadTask.TaskSnapshot>() {        @OverrIDe        public voID onSuccess(fileDownloadTask.TaskSnapshot taskSnapshot) {            //dismiss Progress Dialog\        }    }).addOnFailureListener(new OnFailureListener() {        @OverrIDe        public voID onFailure(@NonNull Exception e) {            //dismiss Progress Dialog\        }    }).addOnProgressListener(new OnProgressListener<fileDownloadTask.TaskSnapshot>() {        @OverrIDe        public voID onProgress(fileDownloadTask.TaskSnapshot taskSnapshot) {            //calculating progress percentage            double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();            //displaying percentage in progress dialog            yourProgressDialog.setMessage("Uploaded " + ((int) progress) + "%...");        }    });
