This is the Onclick method

@Override
public void onClick(View v) {

    int idSelec= grupoRadio.getCheckedRadioButtonId();
    sexo= findViewById(idSelec);
    String sex= sexo.getText().toString();
    String correo= corr.getText().toString();
    String pass=contra.getText().toString().trim();

                switch ( v.getId() ){

                    case R.id.hecho_RU:
                        auth.createUserWithEmailAndPassword(correo,pass).addOnCompleteListener
                                (registroUsuarios.this, new OnCompleteListener<AuthResult>() {
                            @Override
                            public void onComplete(@NonNull Task<AuthResult> task) {
                               if(!task.isSuccessful()){
                                    Toast.makeText(registroUsuarios.this, "Ha ocurrido un error al registrarse, inténtalo de nuevo más tarde", Toast.LENGTH_SHORT).show();
                                }else{
                                   String nombre= nomb.getText().toString();
                                   String apellido=apell.getText().toString();
                                   String mail=corr.getText().toString();
                                   int telefono=Integer.parseInt(tel.getText().toString());
                                   String sex= sexo.getText().toString();
                                   String id_usuario = auth.getCurrentUser().getUid();
                                   DatabaseReference dbRef = FirebaseDatabase.getInstance().getReference().child("Usuarios").child(id_usuario);
                                   Map nuevoMapa = new HashMap();
                                   nuevoMapa.put("Nombre" ,nombre);
                                   nuevoMapa.put("Apellido" ,apellido);
                                   nuevoMapa.put("Correo" ,mail);
                                   nuevoMapa.put("Telefono" ,telefono);
                                   nuevoMapa.put("Sexo" ,sex);
                                   dbRef.setValue(nuevoMapa);
                                   startActivity(new Intent (registroUsuarios.this,login.class));
                               }
                            }
                        });
                        break;
                    case R.id.atrasRU:
                        finish();
                        break;


                }
}

When i had a lot of trouble with dependencies, but everything was pretty well. After some modifications, the create user task from firebase wasn't successful doesn't even know why

One of your `TextView` widgets is `null`. See line 65 of `registroUsuarios.java` to determine which `TextView` that is. — CommonsWare, May 11 '18 at 14:34

make some change below code remove from onclick and i hope you set setonclick list on textview..like below code..

        textView=findViewById(R.id.textview);
    textView.setOnClickListener(this);




int idSelec= grupoRadio.getCheckedRadioButtonId();
sexo= findViewById(idSelec);
String sex= sexo.getText().toString();
String correo= corr.getText().toString();
String pass=contra.getText().toString().trim();
