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。我有以下文件：myapp/res/raw/file.mp3。

我有以下代码，但遗憾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，但是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内捕获，使其看起来根本没有发生任何事情：

Answer 1

您无法从资源设置铃声。

RingtoneManager.setActualDefaultRingtoneUri期望设备中的铃声文件和Uri应来自内容解析器。

 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>

请在此问题中尝试解决方案here

File file = new File(Environment.getExternalStorageDirectory(),
                "/myRingtonFolder/Audio/");
        if (!file.exists()) {
            file.mkdirs();
        }

        String path = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/myRingtonFolder/Audio/";

        File f = new File(path + "/", name + ".mp3");

        Uri mUri = Uri.parse("android.resource://"
                + context.getPackageName() + "/raw/" + name);
        ContentResolver mCr = context.getContentResolver();
        AssetFileDescriptor soundFile;
        try {
            soundFile = mCr.openAssetFileDescriptor(mUri, "r");
        } catch (FileNotFoundException e) {
            soundFile = null;
        }

        try {
            byte[] readData = new byte[1024];
            FileInputStream fis = soundFile.createInputStream();
            FileOutputStream fos = new FileOutputStream(f);
            int i = fis.read(readData);

            while (i != -1) {
                fos.write(readData, 0, i);
                i = fis.read(readData);
            }

            fos.close();
        } catch (IOException io) {
        }
        ContentValues values = new ContentValues();
        values.put(MediaStore.MediaColumns.DATA, f.getAbsolutePath());
        values.put(MediaStore.MediaColumns.TITLE, name);
        values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
        values.put(MediaStore.MediaColumns.SIZE, f.length());
        values.put(MediaStore.Audio.Media.ARTIST, R.string.app_name);
        values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
        values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
        values.put(MediaStore.Audio.Media.IS_ALARM, true);
        values.put(MediaStore.Audio.Media.IS_MUSIC, true);

        Uri uri = MediaStore.Audio.Media.getContentUriForPath(f
                .getAbsolutePath());
        Uri newUri = mCr.insert(uri, values);

        try {
            RingtoneManager.setActualDefaultRingtoneUri(context,
                    RingtoneManager.TYPE_RINGTONE, newUri);
            Settings.System.putString(mCr, Settings.System.RINGTONE,
                    newUri.toString());
        } catch (Throwable t) {

        }

从res / raw文件夹设置铃声
