Turn an ArrayList of filenames to Android resources

Issue

I have in my database a column that stores the filename of the images I'm using in the android application. In most of my activities I need to use a lot of these images.

So I store these filenames in an ArrayList<String>and I want for my output to be an ArrayList<Integer> of Resources IDs of these images.

Based on several questions here on stackoverflow, I used the following technique (got it from this question) :

//  Where tileImageFilenames is the ArrayList<String>

    for(int i=0;i<tileImagesFilename.size();i++)
    {

        tileImagesIDS.add(getResources().getIdentifier(tileImagesFilename.get(i) , "drawable", getApplication().getPackageName()));
    }

This returns me an ArrayList<Integer> full of 0s.

Solution

you must create new object and then add it to your ArrayList<Integer>

for(int i=0;i<tileImagesFilename.size();i++)
    {
        String name =  tileImagesFilename.get(i).replace(".jpg","");
        tileImagesIDS.add(new Integer(getResources().getIdentifier(name , "drawable", getApplication().getPackageName())));
    }
