Insert data into firebase from Alertdialog

Question

Guys I’m having a question, I was wondering if you have how to store data in firebase from a custom Alertdialog?

If I wanted the help of you to create a logic and make this idea happen, I think that for those who are starting it would help a lot.

Obg to all who are determined to help

Answer 1

Well, assuming you’ve already created your Alert or know how to create it because you haven’t posted any code, you can do the following: Assuming the user enters some data in edits, and Alert has a Positive button that will save this information and a model class that will work this data, you will call the model class, which in this example is a user class. In the Model class, in addition to the variables and the getters and setters you will have this method:

public void salvar(){

    DatabaseReference banco = FirebaseDatabase.getInstance().getReference();
    banco.child("USUARIOS").push().setValue(this);
}

Now it is enough that you in the positiveButton method of Alert create the following call:

Usuarios usuarios = new Usuarios();
usuarios.setNome(editNome.getText().toString());
usuarios.setEmail(editEmail.getText().toString());
usuarios.setTelefone(editTelefone.getText().toString());
usuarios.salvar();
dismiss();//para fechar o alert

Or you can do this update without the model class, sending data when it is clicked on the positive Alert button in this way:

DatabaseReference banco = FirebaseDatabase.getInstance().getReference();
    banco.child("USUARIOS").push().setValue("nome", etNome.getText().toString())
    .setValue("email", etEmail.getText().toString());

The two options should work, there is your creitério although I recommend using the model classes to make the work better organized. Any doubt I’m available!
