Android: access drawables outside an activity

Question

How do access a drawable which resides in my project's res/drawable folder from outside an activity? The component which handles the loading of images is generic and is not inside any activity. I would like to display an image from res/drawable in case it can't be fetched from the web.

Thanks, Rob

Answer 1

You need a reference to the Resources object. Easiest way would be to pass a reference to it in the constructor for your component.

Answer 2

You can call it via your package.

For an image, the syntax would be: <your.package.name>.R.drawable.<filename>

Answer 3

Not quite as simple as that Zarah.

Just use PackageManager:

getDrawable (String packageName, int resid, ApplicationInfo appInfo)
