I had the same problem as you and I did the following to solve it     IMAGEVIEW   setImageResource getActivity                 getResources                 getIdentifier    IMG      drawable   getActivity                 getPackageName

The resource drawable names are not stored as strings  so you ll have to resolve the string into the integer constant generated during the build   You can use the Resources class to resolve the string into that integer   Resources res   getResources    int resourceId   res getIdentifier     generatedString   drawable   getPackageName      imageView setImageResource  resourceId      This resolves your generated string into the integer that the ImageView can use to load the right image   Alternately  you can use the id to load the Drawable manually and then set the image using that drawable instead of the resource ID   Drawable drawable   res getDrawable  resourceId    imageView setImageDrawable  drawable

This works  at least in Android API 15  ImageView   imgv  Resources res   getResources       need this to fetch the drawable Drawable draw   res getDrawable  R drawable image name in drawable    imgv setImageDrawable draw     You could use setImageResource    but the documentation specifies that   does Bitmap reading and decoding on the UI thread  which can cause a latency hiccup     consider using setImageDrawable   or setImageBitmap     as stated by chetto

Try this   int id   getResources   getIdentifier  yourpackagename drawable     StringGenerated  null  null     This will return the id of the drawable you want to access    then you can set the image in the imageview by doing the following  imageview setImageResource id

If You cannot get Resources object like this in a class which is not an Activity  you have to add getContext   method for getResources   for example  ImageView image    ImageView  v findViewById R id item image   int id   getContext   getResources   getIdentifier imageName   drawable   getContext   getPackageName     image setImageResource id
