Android AlertDialog bouton unique

Question

J'aimerais créer un AlertDialog qui ne comporte qu'un seul bouton indiquant "OK" ou "Done", au lieu des boutons "yes" et "no" par défaut. Est-ce que cela peut être fait avec l'AlertDialog standard ou dois-je utiliser autre chose ?

Answer 1

Kotlin ?

  val dialogBuilder = AlertDialog.Builder(this.context)
  dialogBuilder.setTitle("Alert")
               .setMessage(message)
               .setPositiveButton("OK", null)
               .create()
               .show()

C'est très simple

new AlertDialog.Builder(this).setView(input).setPositiveButton("ENTER",            
                        new DialogInterface.OnClickListener()                      
                        {   public void onClick(DialogInterface di,int id)     
                            {
                                output.setText(input.getText().toString());
                            }
                        }
                     )
        .create().show();

Dans Mono pour Android, vous pouvez le faire :

var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate { ad.Dispose(); });
ad.Show();
