Question

My android app is basically a simple one where there is one listview with 40 list items. And each of those items when clicked leads one to an image. so there are 40 images.

I can always of-course place those images in the res/drawable folder and refer to them directly from my java file in which case there will be hardcoding done

img.setImageResource(R.drawable.day1);
.
.
.
img.setImageResource(R.drawable.day3);
.
.

.
etc.

Is there anyway (by storing the names of the images in an xml for example) to programatically retrieve the image names from folder and display them ?

Answer 1

int resID = getResources().getIdentifier("day" + i,
    "id", getPackageName());

where i is your index

img.setImageResource(resID);
