问题描述

我试过了这段代码，可以很好地将声音文件加载到铃声目录中.我可以从弹出窗口中手动选择声音.但是无法通过编程将其设置为默认铃声.plz帮助我将声音设置为以编程方式设置默认铃声

        setContentView(R.layout.activity_main);
      String exStoragePath = Environment.getExternalStorageDirectory().getAbsolutePath();
     path=(exStoragePath +"/media/alarms/");
            // saveas();
        saveas(RingtoneManager.TYPE_RINGTONE);

    }

    // In this method, we need to copy the mp3 file to the sd card location from
    // where android picks up ringtone files
    // After copying, we make the mp3 as current ringtone
public boolean saveas(int type) {
enter code here
    byte[] buffer = null;
    InputStream fIn = getBaseContext().getResources().openRawResource(
            R.raw.sound);
    int size = 0;

    try {
        size = fIn.available();
        buffer = new byte[size];
        fIn.read(buffer);
        fIn.close();
    } catch (IOException e) {
        return false;
    }


    String filename = "sound";

    boolean exists = (new File(path)).exists();
    if (!exists) {
        new File(path).mkdirs();
    }

    FileOutputStream save;
    try {
        save = new FileOutputStream(path + filename);
        save.write(buffer);
        save.flush();
        save.close();
    } catch (FileNotFoundException e) {
        return false;
    } catch (IOException e) {

        return false;

    }

    sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + path + filename + ".mp3"
            + Environment.getExternalStorageDirectory())));
enter code here
    File k = new File(path, filename);

    ContentValues values = new ContentValues();
    long current = System.currentTimeMillis();
    values.put(MediaStore.MediaColumns.DATA, path + filename  );
    values.put(MediaStore.MediaColumns.TITLE,  filename );
    values.put(MediaStore.Audio.Media.DATE_ADDED, (int) (current / 1000));
    values.put(MediaStore.Audio.Media.MIME_TYPE, "audio/mp3");

    //new
    values.put(MediaStore.Audio.Media.ARTIST, "cssounds ");
    values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
    values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
    values.put(MediaStore.Audio.Media.IS_ALARM, false);
    values.put(MediaStore.Audio.Media.IS_MUSIC, false);

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



    return true;

}

推荐答案

删除此代码 RingtoneManager.getRingtone(context,this.getContentResolver() .insert(MediaStore.Audio.Media.getContentUriForPath(k .getAbsolutePath()), values));

Remove this code RingtoneManager.getRingtone(context,this.getContentResolver() .insert(MediaStore.Audio.Media.getContentUriForPath(k .getAbsolutePath()), values));

并将这些行代码放在返回true及其工作之前

and put these lines code before return true and its work

 Uri newUri = this.getContentResolver()
            .insert(MediaStore.Audio.Media.getContentUriForPath(k
                    .getAbsolutePath()), values);
    RingtoneManager.setActualDefaultRingtoneUri(MainActivity.this, RingtoneManager.TYPE_RINGTONE, newUri);
