Android 铃声设置界面，起始位置为当前已选项

转载请注明出处！！！

1.调用系统铃声设置的Intent，界面上会弹出选择铃声的对话框。

//用于选择铃声后作相应的判断标记private static final int REQUEST_CODE_PICK_RINGTONE = 1;//保存铃声的Uri的字符串形式private Uri mRingtoneUri = null;


private void doPickRingtone() {        Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);        // Allow user to pick 'Default'        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE,"设置铃声");        // Show only ringtones        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,                RingtoneManager.TYPE_RINGTONE);        // Don't show 'Silent'        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);        Uri ringtoneUri;        if (mRingtoneUri != null) {            ringtoneUri = mRingtoneUri;//            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI,Uri.parse(mRingtoneUri));        } else {            // Otherwise pick default ringtone Uri so that something is            // selected.            ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);        }        // Put checkmark next to the current ringtone for this contact        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,ringtoneUri);        // Launch!        // startActivityForResult(intent, REQUEST_CODE_PICK_RINGTONE);        startActivityForResult(intent, REQUEST_CODE_PICK_RINGTONE);    }


2.选择铃声之后作相应的处理，可以存储到数据库。
    @Override    public void onActivityResult(int requestCode, int resultCode, Intent data) {        try        {            Uri pickedUri =data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);            mRingtoneUri = pickedUri;            RingtoneManager.setActualDefaultRingtoneUri(MainActivity.this,RingtoneManager.TYPE_RINGTONE, pickedUri);            Log.i("pickedUri", mRingtoneUri.toString() + "");        }        catch (Exception e)        {            e.printStackTrace();        }        //得到我们选择的铃声////////将我们选择的铃声设置成为默认//        RingtoneManager.setActualDefaultRingtoneUri(MainActivity.this,RingtoneManager.TYPE_RINGTONE, pickedUri);//        //Uri pickedUri_two = RingtoneManager.setActualDefaultRingtoneUri(MainActivity.this,RingtoneManager.TYPE_ALARM, pickedUri);//        RingtoneManager.setActualDefaultRingtoneUri(MainActivity.this,RingtoneManager.TYPE_NOTIFICATION, pickedUri);    }
