Glide - How load image before dialog show?

Question

I'm working with Glide for server loading images. I need to load image before some dialog shows.

What is the best approach?

EDIT: This is an example from my code:

    On my dialog class

    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        setContentView(R.layout.dialog_alert);
        ButterKnife.bind(this);

        int size = mActivity.getResources().getDimensionPixelSize(R.dimen.product_icon);
        String productThumbnailUrl = api.getThumbnailUrl(mProduct.getImage(), size, size);

        Glide.with(mActivity)
        .load(productThumbnailUrl)
        .placeholder(R.drawable.icon_default)
        .into(mImage);
    }

    On my activity:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        [...]

        AlertProduct dialog = new AlertProduct(this, product);
        dialog.show();
    }

Loading into targets should do what you want.

If you simply want to load a Bitmap so that you can interact with it in some special way other than displaying it directly to the user, maybe to show in a notification, or upload as a profile photo, Glide has you covered.

SimpleTarget provides reasonable default implementations for the much larger Target interface and let's you focus on handling the result of your load.
