android如何替換contact的來電鈴聲

標籤：來電鈴聲

如果知道contactId,那麼可以這樣擷取已有的ringtone:

 public String getContactRington(long contactId) {        String rington = "";        String[] projection = { ContactsContract.Contacts.CUSTOM_RINGTONE };        Uri contactUri = ContentUris.withAppendedId(                ContactsContract.Contacts.CONTENT_URI, contactId);        Cursor cursor = this.getContentResolver().query(contactUri,                projection, null, null, null);        if (cursor == null) {            return rington;        }        while (cursor.moveToNext()) {            rington = cursor.getString(0);            break;        }        cursor.close();        return rington;    }

用以下代碼可以去調用系統介面改變鈴聲:

 private void doPickRingtone(String ringtones) {        Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,                RingtoneManager.TYPE_RINGTONE);        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);        try {            Uri ringtoneUri;            if (ringtones != null                    && ringtones.length() > 0) {                ringtoneUri = Uri.parse(ringtones);            } else {                ringtoneUri = RingtoneManager                        .getDefaultUri(RingtoneManager.TYPE_RINGTONE);            }            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,                    ringtoneUri);            startActivityForResult(intent, RESUTL_RINGTONE_PICKED);        } catch (Exception ex) {            MktLog.i(TAG,"doPickRingtone:" + ex.toString());        }    }

選擇鈴聲完點擊確認:

  private void handleRingtonePicked(Uri pickedUri) {        updateContactRington(mContactId,pickedUri.toString());    }    public boolean updateContactRington(long contactId, String rington) {        ContentValues values = new ContentValues();        values.put(ContactsContract.Contacts.CUSTOM_RINGTONE, rington);        Uri contactUri = ContentUris.withAppendedId(                ContactsContract.Contacts.CONTENT_URI, contactId);        this.getContentResolver().update(contactUri, values, null, null);        return true;    }
