“mplaceholder”在android开发人员“处理UI线程中的位图”中引用了什么？

Question

I am working with bitmaps and trying to follow the guidliness provided in android developer site. I have followed all the steps in detail however i am stuck with a parameter passed in the following method.

    public void loadBitmap(int resId, ImageView imageView) {
    if (cancelPotentialWork(resId, imageView)) {
        final BitmapWorkerTask task = new BitmapWorkerTask(imageView);
        final AsyncDrawable asyncDrawable =
                new AsyncDrawable(getResources(), **mPlaceHolderBitmap**, task);
        imageView.setImageDrawable(asyncDrawable);
        task.execute(resId);
    }
}

here is the link that i am following. And I am storing and retrieving images from sqlite database however that is not a problem.

@murli...

It represents your own Bitmap to be used as a placeholder while the actual image is loaded. You can download the sample and see the entire code
