Question

I have many text files and want to put them in a for loop.

I get an Extra that have Resource name from last activity (s)
and have an array that have Resource name of
my text files in raw Resource is from {d0,d1,d2,d3, …,d79}
and I want to check name(s) and array name and put the find name to resource!
I have error on (res=R.raw.(d[i]))
my code :

    int res = 0;
    for (int i = 0; i <=79; i = i + 1) {
        if (s.equals(d[i])){
            res=R.raw.(d[i])
        }
    } 
    inputstream = getResources().openRawResource(res);

Answer 1

You can use getIdentifier (String name, String defType, String defPackage) for fetching resource id dynamically,

ArrayList<Integer> id = new ArrayList<Integer>();
for (int i = 0; i <= 79; i++) {
  id.add(getResources().getIdentifier("d"+i, "raw", getPackageName()));
}

Now you will have all the resources id’s inside id ArrayList
