android - 从 res/raw 文件夹设置铃声

Question

我正在尝试以编程方式将 /res/raw/ 文件夹中的音频文件设置为默认铃声。我有如下文件:myapp/res/raw/file.mp3。

我有下面的代码，但不幸的是它完全无法设置铃声。我不确定是什么导致了这个问题，但想知道是否有人有任何见解可以分享。

Uri path = Uri.parse("android.resource://com.mikan.myapp/res/raw/file.mp3");
        RingtoneManager.setActualDefaultRingtoneUri(
                getApplicationContext(), RingtoneManager.TYPE_RINGTONE,
                path);
        Log.i("TESTT", "Ringtone Set to Resource: "+ path.toString());
        RingtoneManager.getRingtone(getApplicationContext(), path)
                .play();

我收到以下异常(在 RingtoneManager 中捕获，让它看起来好像什么都没发生:

Answer 1

您不能从资源中设置铃声。

RingtoneManager.setActualDefaultRingtoneUri 需要设备中的铃声文件，Uri 应该来自内容解析器。

 File ring = new File("pathOfYourFile");
 Uri path = MediaStore.Audio.Media.getContentUriForPath(ring.getAbsolutePath());
 RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(), RingtoneManager.TYPE_RINGTONE,path);

还要确保添加权限

 <uses-permission android:name="android.permission.WRITE_SETTINGS" ></uses-permission>
