如何以编程方式更改 Android 中的铃声？

发布于 2024-11-10 13:49:05 字数 533 浏览 4 评论 0原文

我正在尝试编写一个应用程序（除其他外）将根据用户的位置更改用户的铃声。

但是，我在应用程序中设置手机铃声时遇到困难。我已经能够显示手机铃声列表，并且一直在使用以下代码来尝试设置铃声：

RingtoneManager.setActualDefaultRingtoneUri(applicationContext, 
      RingtoneManager.TYPE_RINGTONE,
      MediaStore.Audio.Media.getContentUriForPath(settings.getRingtoneURI()));

Settings.System.putString(c.getContentResolver(), Settings.System.RINGTONE, 
      settings.getRingtoneURI());

其中 settings.getRingtoneURI() 返回一个包含所需铃声 URI 的字符串。

当我运行它时，我没有收到任何错误，但铃声没有改变。

有什么建议吗？

I'm trying to write an app that (among other things) will change the user's ringtone based on their location.

However, I'm having difficulty setting the ringtone of my phone from within my app. I've been able to display a list of the phone's ringtones, and have been using the following code to try and set the ringtone:

RingtoneManager.setActualDefaultRingtoneUri(applicationContext, 
      RingtoneManager.TYPE_RINGTONE,
      MediaStore.Audio.Media.getContentUriForPath(settings.getRingtoneURI()));

Settings.System.putString(c.getContentResolver(), Settings.System.RINGTONE, 
      settings.getRingtoneURI());

where settings.getRingtoneURI() returns a string with the URI of the desired ringtone.

When I run this, I receive no errors but the ringtone does not change.

Any advice?

下面的代码选择来自手机的任何随机铃声作为来电。

            RingtoneManager rm = new RingtoneManager(context);
    Random random = new Random();

    int i = rm.getRingtonePosition(RingtoneManager
            .getActualDefaultRingtoneUri(context,
                    RingtoneManager.TYPE_RINGTONE));
    MyApplication.APPLICATION_SHARED_PREFERENCE.edit()
            .putInt(MyConstants.PHONE_RINGTONE_NUMBER, i).commit();
    int chanegToneNumber;
    Cursor cursor = rm.getCursor();

    while (true) {
        chanegToneNumber = random.nextInt(cursor.getCount());
        if (chanegToneNumber != i)
            break;
    }

    Log.d(TAG, "Tone: " + i);

    Log.d(TAG, "Tone total: " + cursor.getCount());

    while (cursor.moveToNext()) {

        if (i == cursor.getInt(cursor
                .getColumnIndex(MediaStore.MediaColumns._ID))) {
            RingtoneManager.setActualDefaultRingtoneUri(context,
                    RingtoneManager.TYPE_RINGTONE,
                    rm.getRingtoneUri(chanegToneNumber));
            break;
        }
    }

The below code choose any random tone from the mobile for Incoming call.

            RingtoneManager rm = new RingtoneManager(context);
    Random random = new Random();

    int i = rm.getRingtonePosition(RingtoneManager
            .getActualDefaultRingtoneUri(context,
                    RingtoneManager.TYPE_RINGTONE));
    MyApplication.APPLICATION_SHARED_PREFERENCE.edit()
            .putInt(MyConstants.PHONE_RINGTONE_NUMBER, i).commit();
    int chanegToneNumber;
    Cursor cursor = rm.getCursor();

    while (true) {
        chanegToneNumber = random.nextInt(cursor.getCount());
        if (chanegToneNumber != i)
            break;
    }

    Log.d(TAG, "Tone: " + i);

    Log.d(TAG, "Tone total: " + cursor.getCount());

    while (cursor.moveToNext()) {

        if (i == cursor.getInt(cursor
                .getColumnIndex(MediaStore.MediaColumns._ID))) {
            RingtoneManager.setActualDefaultRingtoneUri(context,
                    RingtoneManager.TYPE_RINGTONE,
                    rm.getRingtoneUri(chanegToneNumber));
            break;
        }
    }
