Question

The API says that the Alert Dialog can have one, two or three buttons, but the SDK only allows for a positive and negative button. How then can I add a third button?

Answer 1

This code snippet should help explain the three different buttons you can use:

    alertDialog = new AlertDialog.Builder(this).create();

    alertDialog.setTitle("Dialog Button");

    alertDialog.setMessage("This is a three-button dialog!");

    alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "Button 1 Text", new DialogInterface.OnClickListener() {

      public void onClick(DialogInterface dialog, int id) {

        //...

    } }); 

    alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Button 2 Text", new DialogInterface.OnClickListener() {

      public void onClick(DialogInterface dialog, int id) {

        //...

    }}); 

    alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "Button 3 Text", new DialogInterface.OnClickListener() {

      public void onClick(DialogInterface dialog, int id) {

        //...

    }});
