Android铃声管理器“标题”和“艺术家”信息

Question

我设置铃声，它工作正常，但“.MediaColumns.TITLE”和“.Media.ARTIST”不起作用。我已经设置了铃声，然后我检查。显示文件名称而不是“标题名称”。

我的代码;

public boolean setRingtone(int p, String s) { 

    String path = Environment.getExternalStorageDirectory().getPath() 
      + "/sdcard/media/audio/ringtones/"; 
    String filename = s+'.mp3'; 

    boolean exists = (new File(path)).exists(); 
    if (!exists) { 
     new File(path).mkdirs(); 
    } 

    File k = new File(path, filename); 

    ContentValues values = new ContentValues(); 
    values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath()); 
    values.put(MediaStore.MediaColumns.TITLE, "Title Name"); 
    values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3"); 
    values.put(MediaStore.Audio.Media.ARTIST, "Ringtones"); 
    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); 

    Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath()); 

    getContentResolver().delete(uri,MediaStore.MediaColumns.DATA + "=\"" + k.getAbsolutePath() + "\"", null); 

    Uri newUri = getContentResolver().insert(uri,values); 
    RingtoneManager.setActualDefaultRingtoneUri(SingleListItem.this,RingtoneManager.TYPE_RINGTONE,newUri); 

    String desc= "Ringtone has been set"; 

    Toast.makeText(getApplicationContext(), desc, Toast.LENGTH_LONG).show(); 
    return true; 

}

你插入看起来是正确的......我用几乎相同的代码和它的作品。它在哪里显示文件名而不是“标题名称”？在电话设置中还是当您再次查询数据库中的媒体条目时？如果是在查询时，请确保您索引到正确的列以获得字符串：

Uri ringtoneUri = ...however you are getting the URI... 
String[] retCol = { MediaStore.MediaColumns.TITLE }; 
Cursor cur = context.getContentResolver().query(ringtoneUri,retCol,null,null, null); 
if (cur.getCount() > 0) { 
    cur.moveToFirst(); 
    String name = cur.getString(cur.getColumnIndex(MediaStore.MediaColumns.TITLE)); 
    //Do something with name... 
} 
cur.close();
