My friends have a problem, I tried to understand the operation of AlertDialog, where the focus was to create two buttons to confirm the dialog. The code I'm using is this:
import android.content.Context;
import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.telephony.SmsManager;
import android.widget.EditText;
import android.widget.Toast;
import java.util.ArrayList;
/**

public class Manager{
public static void Enviar(Context context, EditText[] Text, String opcao) {
if (Manager.CheckEditText(Text) == 0) {
Toast.makeText(context, "Preencha os campos, nome, telefone com DDD e a mensagem para enviar a mesma.", Toast.LENGTH_SHORT).show();
return;
}
if (Manager.CheckEditText(Text) == 1)
{
Toast.makeText(context, "Informe o DDD e o telefone, para continuar.", Toast.LENGTH_SHORT).show();
return;
}
if (Confirm(context)){
SmsManager smsManager = SmsManager.getDefault();
String Telefone = "12997040012";
String Mensagem = opcao + Text[0].getText().toString() + "\nRemetente: " + Text[1].getText().toString() + "\n" + Text[2].getText().toString();
ArrayList<String> smsEmPartes = smsManager.divideMessage(Mensagem);
smsManager.sendMultipartTextMessage(Telefone, null, smsEmPartes, null, null);
Toast.makeText(context, "Mensagem enviada com sucesso", Toast.LENGTH_LONG).show();
}
}
public static boolean Confirm(Context context) {
final boolean[] retorno = new boolean[1];
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
dialog.setMessage("Deseja realmente enviar a mensagem?");
dialog.setPositiveButton("Sim", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface di, int arg) {
retorno[0] = true;
}
});
dialog.setNegativeButton("Não", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface di, int arg) {
retorno[0] = false;
}
});
dialog.setTitle("Confirmação");
dialog.show();
return retorno[0];
}
public static short CheckEditText(EditText[] Campos){
for (int i = 0; i<Campos.length; ++i){
if (Campos[i].getText().length() == 0){
return 0;
}
}
if (Campos[2].length() < 10) {
return 1;
}
return 2;
}
}
And when I run this function I get the following exception:

What I want to do is display a dialog when the user clicks the submit button, this dialog will ask a simple question to the user if he wants to confirm the action. If you know a way to create this dialog and make it work I thank you.
