我正在尝试找到一种方法来通过我的 Android 活动中的代码设置新的默认铃声。
我已经把铃声下载到了bytearray
.
最后,我设法将默认铃声设置为我下载的铃声。下面不包含下载代码,仅包含将其设置为默认铃声所需的代码。
File k = new File(path, "mysong.mp3"); // path is a file to /sdcard/media/ringtone
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "My Song title");
values.put(MediaStore.MediaColumns.SIZE, 215454);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.Audio.Media.ARTIST, "Madonna");
values.put(MediaStore.Audio.Media.DURATION, 230);
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);
//Insert it into the database
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
Uri newUri = this.getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(
myActivity,
RingtoneManager.TYPE_RINGTONE,
newUri
);
无论如何,我不完全理解这段代码在做什么。
铃声管理器需要一个指向要设置为新铃声的文件的 uri。但是这个uri不能像“/sdcard/media/ringtones/mysong.mp3”这样直接到sdcard。那是行不通的!
您需要的是文件的外部文件 uri,可能类似于“/external/audio/media/46”
46是MediaStore数据库中列的id,所以需要先将sdcard文件添加到数据库中。
无论如何,mediastore 是如何维护它的 id 的呢?这个数字可能会变得非常高,因为您多次执行此操作。
我需要自己删除这一行吗?问题是有时我什至无法控制文件的删除,因为可以使用文件浏览器直接从 sdcard 中删除它。
Answer By Vidar 太长,每次您想将歌曲设置为铃声时,它都会添加重复的条目。相反,你应该试试这个
Uri newUri=Uri.parse("content://media/external/audio/media/"+ID);
try {
RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, newUri);
}
catch (Throwable t) {
}
public void setRingtone() {
String ringtoneuri = Environment.getExternalStorageDirectory().getAbsolutePath() + "/media/ringtone";
File file1 = new File(ringtoneuri);
file1.mkdirs();
File newSoundFile = new File(ringtoneuri, "myringtone.mp3");
Uri mUri = Uri.parse("android.resource://globalapps.funnyringtones/raw/sound_two.mp3");
ContentResolver mCr = this.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/mp3");
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 {
Uri rUri = RingtoneManager.getValidRingtoneUri(this);
if (rUri != null)
ringtoneManager.setStopPreviousRingtone(true);
RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(), RingtoneManager.TYPE_RINGTONE, newUri);
Toast.makeText(this, "New Rigntone set", Toast.LENGTH_SHORT).show();
} catch (Throwable t) {
Log.e("sanjay in catch", "catch exception"+e.getMessage());
}
}
您可以使用内置的RingtonePreference类。AndroidGuys 在这里有一个很好的教程。
这是我使用的代码!我希望它有帮助..
这也是链接。
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);
快乐编码!
我无法评论该解决方案,因为我在堆栈溢出方面没有足够的声誉......我只想添加一种将音频文件添加到媒体数据库中的方法,而无需直接访问数据库,从而避免重复。该解决方案基于 MediaScannerConnection,这是我使用的代码:
String[] files = { audioFullPath };
MediaScannerConnection.scanFile(
getApplicationContext(),
files,
null,
new OnScanCompletedListener() {
@Override
public void onScanCompleted(String path, Uri uri) {
Log.v("myapp", "file " + path + " was scanned seccessfully: " + uri);
}
}
);
我已经尝试了这些代码它的帮助
private void setRingtone(Context context, String path) {
if (path == null) {
return;
}
File file = new File(path);
ContentValues contentValues = new ContentValues();
contentValues.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
String filterName = path.substring(path.lastIndexOf("/") + 1);
contentValues.put(MediaStore.MediaColumns.TITLE, filterName);
contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
contentValues.put(MediaStore.MediaColumns.SIZE, file.length());
contentValues.put(MediaStore.Audio.Media.IS_RINGTONE, true);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(path);
Cursor cursor = context.getContentResolver().query(uri, null, MediaStore.MediaColumns.DATA + "=?", new String[]{path}, null);
if (cursor != null && cursor.moveToFirst() && cursor.getCount() > 0) {
String id = cursor.getString(0);
contentValues.put(MediaStore.Audio.Media.IS_RINGTONE, true);
context.getContentResolver().update(uri, contentValues, MediaStore.MediaColumns.DATA + "=?", new String[]{path});
Uri newuri = ContentUris.withAppendedId(uri, Long.valueOf(id));
try {
RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, newuri);
Toast.makeText(context, "Set as Ringtone Successfully.", Toast.LENGTH_SHORT).show();
} catch (Throwable t) {
t.printStackTrace();
}
cursor.close();
}
}
使用此功能设置铃声
private void setAsRingtone(String musicId) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (Settings.System.canWrite(this)) {
Uri uri = ContentUris.withAppendedId(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, Long.parseLong(musicId));
RingtoneManager.setActualDefaultRingtoneUri(
this,
RingtoneManager.TYPE_RINGTONE,
uri
);
Toast.makeText(this, "Ring set successfully", Toast.LENGTH_SHORT).show();
} else {
Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS);
intent.setData(Uri.parse("package:" + getPackageName()));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
}
音乐 ID 可以从光标处获得。希望您知道,或 在此处查看
提供铃声选择的意图。
final Uri currentTone= RingtoneManager.getActualDefaultRingtoneUri(MainActivity.this, RingtoneManager.TYPE_ALARM);
Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_RINGTONE);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Tone");
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, currentTone);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
startActivityForResult(intent, 999);
然后在 中捕获选择的结果onActivityResult
。
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 999 && resultCode == RESULT_OK){
Uri uri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
txtView.setText("From :" + uri.getPath());
//Set selected ringtone here.
RingtoneManager.setActualDefaultRingtoneUri(
this,
RingtoneManager.TYPE_RINGTONE,
uri
);
}
}
如果接受的答案不起作用,请使用:
MediaStore.Audio.Media.INTERNAL_CONTENT_URI
而不是这个:
MediaStore.Audio.Media.getContentUriForPath()
在将值插入数据库时。
例如 :
// Defining ringtone.....
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "Sonify");
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
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);
// Setting ringtone....
getContentResolver().delete(MediaStore.Audio.Media.INTERNAL_CONTENT_URI,MediaStore.Audio.Media.TITLE + " = \"Sonify\"",null);
// To avoid duplicate inserts
Uri ringUri = getContentResolver().insert(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, values);
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, ringUri);
不要忘记添加
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
我从 Android 的媒体应用程序中找到了这段代码。
Settings.System.putString(resolver,
Settings.System.RINGTONE, ringUri.toString());
这是我的作品。
