Android How To Make an AlertDialog

To make an AlertDialog you have to write this code:

AlertDialog.Builder alertDelete = new AlertDialog.Builder(ListsActivity.this);
//HERE YOU WILL WRITE THE MESSAGE YOU WANT
alertDelete.setMessage(R.string.delete_confirm);
//HERE IS THE POSITIVE BUTTON. YOU HAVE TO SET THE BUTTON NAME AND A CLICK LISTENER
alertDelete.setPositiveButton(getString(R.string.yes),new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//YOUR ACTION
}
});

//HERE IS THE CANCEL BUTTON. YOU HAVE TO SET THE BUTTON NAME AND A CLICK LISTENER
alertDelete.setNeutralButton(getString(R.string.cancel),new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int i) {
dialog.cancel();
}
});
alertDelete.show();

And now the result:
