如何使用設備上的數據庫設置鈴聲？

我想使用我的設備中的數據庫設置鈴聲。我的應用程序能夠從設備獲取鈴聲並將其存儲在數據庫中。現在，我想要做的是無論我通過微調器選擇的鈴聲，它設置爲我的默認鈴聲。如何使用設備上的數據庫設置鈴聲？

這裏是我的代碼

public class SMSReceiver extends BroadcastReceiver{ 

    DBAdapter db ; 
    int vol = 7; 
    String code=""; 
     @Override 
    public void onReceive(Context context, Intent intent) { 
    contextx=context; 
     Bundle bundle = intent.getExtras(); 
     // TODO Auto-generated method stub 
     db = new DBAdapter(context); 
     db.open(); 

     Cursor c = db.getAllTitles(); 
     int row_size = c.getCount(); 
     System.out.println("row size++++++++"+row_size); 
     if(row_size>0) 
     { 
      c.moveToFirst(); 
      code = c.getString(1); 
      String status = c.getString(2); 
      String ring = c.getString(3); 
      vol = c.getInt(4); 
      String mode = c.getString(5); 

      System.out.println("code++++++++"+code); 
      System.out.println("status++++++++"+status); 
      System.out.println("ring++++++++"+ring); 
      System.out.println("vol++++++++"+vol); 
      System.out.println("mode++++++++"+mode); 

        File path = Environment.getExternalStoragePublicDirectory(
        Environment.DIRECTORY_RINGTONES); 
     File Ringtonefile = new File(path,ring); 
     setMyRingtone(Ringtonefile) ; 
     } 

     Object messages[] = (Object[]) bundle.get("pdus"); 
      SmsMessage smsMessage[] = new SmsMessage[messages.length]; 
      for (int n = 0; n < messages.length; n++) { 
       smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]); 
      } 

      if(smsMessage[0].getMessageBody().equals(""+code)) 
      { 
       AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE); 

        audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL); 
       audioManager.setStreamVolume(AudioManager.STREAM_RING, vol, AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND); 

      } 
      } 

    public void setMyRingtone(File file) 
{ 
    ContentValues values = new ContentValues(); 
    values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath()); 
    values.put(MediaStore.MediaColumns.TITLE, file.getName()); 
    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); 

    Uri uri = MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath()); 
    Uri newUri = contextx.getContentResolver().insert(uri, values); 
    RingtoneManager.setActualDefaultRingtoneUri(contextx, RingtoneManager.TYPE_RINGTONE, newUri);} }

試試這個設置默認鈴聲使用RingtoneManager：

public class SMSReceiver extends BroadcastReceiver{ 
Context contextx; 
    DBAdapter db ; 
    int vol = 7; 
    String code=""; 
        @Override 
    public void onReceive(Context context, Intent intent) { 
     this.contextx=context; 
     //your code.... 


    File Ringtonefile = new File(path, "Ringtone.mp3"); 
    setMyRingtone(Ringtonefile) ; 
    public void setMyRingtone(File file) 
     { 
      ContentValues values = new ContentValues(); 
      values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath()); 
      values.put(MediaStore.MediaColumns.TITLE, file.getName()); 
    //  values.put(MediaStore.MediaColumns.SIZE, file.length()); 
      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); 

      Uri uri = MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath()); 
      Uri newUri = contextx.getContentResolver().insert(uri, values); 
      RingtoneManager.setActualDefaultRingtoneUri(contextx, RingtoneManager.TYPE_RINGTONE, newUri); 
     }

我能做到不使用烏里@ imran ?? –

@JasmeetKaurChauhan：setActualDefaultRingtoneUri（上下文環境，int類型，Uri ringtoneUri）將第二個參數作爲Uri使用，所以我認爲這不適用於Uri。 –

@JasmeetKaurChauhan：你目前如何在數據庫中存儲鈴聲？ –
