Send number from NumberPicker to Firebase

Is there a way to send Number from NumberPicker to Firebase? I have connected a NumberPicker library from GITHUB. But I want when select number to send to Firebase, is there a way ?

I tried with this code :

 String number = numberPicker.getText().toString().trim();

Code for Firebase:

private boolean updateProdus(String id, String number){

    DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference("produse").child(id);

    Produse produse = new Produse(id, number);

    databaseReference.setValue(produse);
    Toast.makeText(this, "Edited", Toast.LENGTH_LONG).show();
    return true;
}

But it's not working.

private boolean updateProdus(String id, String number){

DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference("produse").push();

databaseReference.child("number").setValue(number);
Toast.makeText(this, "Edited", Toast.LENGTH_LONG).show();
return true;
}

Use push() to create a random id, then inside of it there will be a child that has the value number.

check this: https://developer.android.com/reference/android/widget/NumberPicker.html

you can get the number doing this:

String number=""+numberpicker.getValue();
