如何使用Android中的铃声选择器优先存储选定的铃声？

Question

final Uri currentTone= RingtoneManager.getActualDefaultRingtoneUri(Notification_Settings_Activity.this, RingtoneManager.TYPE_ALARM);
Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_ALARM);
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, TONE_PICKER);

我使用此代码来拾取音调
