I suggest you use this. It makes it so simple:

AlertDialog.Builder dialog = new AlertDialog.Builder(RegistrationActivity.this);
dialog.setCancelable(false);
dialog.setTitle("Error Alert");
dialog.setMessage(info[1]);
dialog.setPositiveButton("ok", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int id) {
        Intent intent = new Intent(RegistrationActivity.this, RegistrationActivity.class);

        startActivity(intent);
    }
})
.setNegativeButton("", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    }
});

final AlertDialog alert = dialog.create();
alert.show();

info[1] is my data which is shown. You can replace this with your own message.
