Установка пользовательского ключа при добавлении данных в firebase при использовании класса модели

Question

Я пытаюсь выдвинуть данные в моей базе данных с помощью модели. Однако при отправке данных я получаю уникальный идентификатор, но я хочу использовать текст с использованием newBeach.setName (beach_item.getText (). ToString ()); сохранить как ID.

Скриншоты:

База данных: вместо -LcLghuLREw86jyLHwMF я хочу использовать "sap", полученный мной через newBeach.setName (beach_item.getText (). ToString ());

Коды: uploadImage

    private void uploadImage() {
    if(saveUri != null)
    {
        final ProgressDialog mDialog = new ProgressDialog(getActivity());
        mDialog.setMessage("Uploading");
        mDialog.show();

        String imageName = UUID.randomUUID().toString();
        final StorageReference imageFolder = storageReference.child("image/*"+imageName);
        imageFolder.putFile(saveUri)

Мы можем достичь этого просто так:

DatabaseReference mRdb=FirebaseDatabase.getInstance().getReference();
String key = mRdb.push().getKey();

//set here as you want
key = "sap";

mRdb.child(key).setValue(value);
