Good morning gentlemen, I’m with a doubt, I’m trying to call a method that is in another class but is not working, this same method already works if using another layout, just wanted to implement it in activity_main, could help me ?
Parameter Class code that is working:
public class Parametro extends AppCompatActivity implements View.OnClickListener{
DadosOpenHelper db = new DadosOpenHelper(this);
public EditText selecinfo;
public EditText selecinfo2;
public Button btncontador;
public Button btncontador2;
public Button btncontador3;
public Button btnemail;
public Button btnemitente;
public Button btnemitente2;
public Button btnemitente3;
public Button btnimpressora;
public Button btnimpressora2;
public Button btnimpressora3;
public Button btnrzaosocial;
public Button btnnomefantasia;
public Button btnie;
public Button btncnpj;
public Button gravar;
public Button gravar2;
public String tabela;
public String descricao;
public String retorno;
public int valida = 1;
@SuppressLint("WrongViewCast")

}

}
}
Code where I’m trying to pull on mainactivity :
public void incluiparam(View view) {
Parametro parameto = new Parametro();
parameto.onClick(view);
}
Remembering that I am trying to pull the "onClick", I do not know if it is possible, if someone can help me I am grateful.
and if you put the method as static?
static– Eduardo Mior
I tested with Static also but did not work

You’re trying to use a function of an Activity in another Activity is this ? you can talk more of the problem maybe we can give you another solution .
– Ricardo Lucas
That’s right, the onClick function is in Activity Parametro and I’m trying to use it in Maiactivity
– Dev
just call the function implicitly :
new Parametro().onClick()(do not forget to put the method as Static)– Walter Felipe
