在我的Android应用程序中,我想将raw
文件夹中的音频文件设置为铃声。
为此我写了下面的代码,但它不起作用。
请帮我解决这个问题。 谢谢。
代码:
String name =best_song_ever.mp3;
File newSoundFile = new File("/sdcard/media/ringtone",
"myringtone.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(newSoundFile);
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,
newSoundFile.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "my ringtone");
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/oog");
values.put(MediaStore.MediaColumns.SIZE, newSoundFile.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, false);
Uri uri = MediaStore.Audio.Media
.getContentUriForPath(newSoundFile.getAbsolutePath());
Uri newUri = mCr.insert(uri, values);
try {
RingtoneManager.setActualDefaultRingtoneUri(context,
RingtoneManager.TYPE_RINGTONE, newUri);
} catch (Throwable t) {
}
Toast.makeText(context, name + " is set as ringtone.",
Toast.LENGTH_LONG).show();
}

以下代码解决了我的问题:
String name = "your_raw_audio_name";
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) {}

如果您想再次设置与铃声相同的res,则以下修改可能会有所帮助
Uri uri = MediaStore.Audio.Media.getContentUriForPath(f
.getAbsolutePath());
mCr.delete(uri, MediaStore.MediaColumns.DATA + "=\"" + f.getAbsolutePath() + "\"", null);
Uri newUri = mCr.insert(uri, values);

这是我使用的代码:对我非常有用:)
String exStoragePath = Environment.getExternalStorageDirectory().getAbsolutePath();
String path=(exStoragePath +"/media/alarms/");
saveas(RingtoneManager.TYPE_RINGTONE);
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+path+filename+".mp3"
+ Environment.getExternalStorageDirectory())));
File k = new File(path, filename);
ContentValues values = new ContentValues(4);
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/3gpp");
//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, true);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
// Insert it into the database
this.getContentResolver()
.insert(MediaStore.Audio.Media.getContentUriForPath(k
.getAbsolutePath()), values);
