Android Programming: YES/NO Dialog Box

In this tip, I would like to show you how to display a dialog in Android which contains an arbitrary question as well as a YES and a NO button and how to assign actions to these buttons.

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Title");
builder.setMessage("Is this a question?");


builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

   @Override
   public void onClick(DialogInterface dialog, int which) {
        
        // Code that is executed when clicking YES

        dialog.dismiss();
   }

});


builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

   @Override
   public void onClick(DialogInterface dialog, int which) {

        // Code that is executed when clicking NO

        dialog.dismiss();
   }

});


AlertDialog alert = builder.create();
alert.show();

We are using AlterDialog.Builder for this. First of all, we are setting the title and the text (question) that should be shown in the dialog. After that, we are defining the actions for the YES and the NO button.

Of course, at this point you can write any code you want, for example you can call a function.
