将android.net.Uri转换为java.net.URL

Question

I used code from CODE and I want to use images from my drawables folder, however the code requires a URL.

I tried to do:

 android.net.Uri aURI = Uri.parse("android.resource://com.kapsapetapp.kapsapet" + R.drawable.icon_bar);
    try {
        java.net.URI jURI = new java.net.URI(aURI.toString());
        URL url =  jURI.toURL();
        imgLoader.DisplayImage(url.getPath(), loader, iconBar_View);
    } catch (URISyntaxException e) {
        e.printStackTrace();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }

However it didn't load the image. What can fix this?

Answer 1

To show image from drawables no need to use java.net.URI . do it as:

Uri uriImage = Uri.parse("drawable://" + R.drawable.icon_bar);  
imgLoader.DisplayImage(String.valueOf(uriImage), loader, iconBar_View);
