如何从原始文件夹设置通知声音

如何解决如何从原始文件夹设置通知声音

我下面的代码使电话的默认通知声音（实际上它使所有声音都为空）为空，但不会使用我的原始文件夹中名为“fine”的 .wav 文件更改它。它向目录添加了一些名为音乐文件的编号，但我无法播放它们。稍后我将在按钮中使用该代码。我的首要目标是让它在应用运行时正常工作。

    String exStoragePath = Environment.getExternalStorageDirectory().getAbsolutePath();
    String path=(exStoragePath +"/media/music/");

    File k = new File(path,"fine");
private boolean SetAsringtoneOrNotification(File k,int type) {


    ContentValues values = new ContentValues();
    values.put(MediaStore.MediaColumns.TITLE,"title");
    values.put(MediaStore.MediaColumns.MIME_TYPE,"audio/MPEG");
    values.put(MediaStore.Audio.Media.ARTIST,R.string.app_name);
    values.put(MediaStore.Audio.Media.IS_ringtone,false);
    values.put(MediaStore.Audio.Media.IS_NOTIFICATION,true);
    values.put(MediaStore.Audio.Media.IS_ALARM,false);
    values.put(MediaStore.Audio.Media.IS_MUSIC,false);
    if (ringtoneManager.TYPE_ringtone == type) {
        values.put(MediaStore.Audio.Media.IS_ringtone,true);
    } else if (ringtoneManager.TYPE_NOTIFICATION == type) {
        values.put(MediaStore.Audio.Media.IS_NOTIFICATION,true);
    }


    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        Uri newUri = getContentResolver().insert(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,values);
        try (OutputStream os = getContentResolver().openOutputStream(newUri)) {

            int size = (int) k.length();
            byte[] bytes = new byte[size];
            try {
                BufferedInputStream buf = new BufferedInputStream(new FileInputStream(k));
                buf.read(bytes,bytes.length);
                buf.close();

                os.write(bytes);
                os.close();
                os.flush();
            } catch (IOException e) {
                return false;
            }
        } catch (Exception ignored) {
            return false;
        }


        try (OutputStream os = getContentResolver().openOutputStream(newUri)) {
            //copy your file from asset into os here
        } catch(Exception ignored) {
        }

        ringtoneManager.setActualDefaultringtoneUri(MainActivity.this,ringtoneManager.TYPE_NOTIFICATION,newUri);

        return true;
    } else {
        values.put(MediaStore.MediaColumns.DATA,k.getAbsolutePath());

        Uri uri = MediaStore.Audio.Media.getContentUriForPath(k
                .getAbsolutePath());

        getContentResolver().delete(uri,MediaStore.MediaColumns.DATA + "=\"" + k.getAbsolutePath() + "\"",null);


        Uri newUri = MainActivity.this.getContentResolver().insert(uri,values);


        this.getContentResolver()
                .insert(MediaStore.Audio.Media.getContentUriForPath(k
                        .getAbsolutePath()),values);


        ringtoneManager.setActualDefaultringtoneUri(MainActivity.this,newUri);

        return true;
    }
