set image with setImageResource in Android Studio using a variable

Question

I am trying to set my image in my ImageView through a variable (item is the variable name, which I will be setting to lowerCase). However, it is not working and resID will return 0.

Here is my code:

    ImageView iv = (ImageView)v.findViewById(R.id.imgView);

    if (item != null) {
        Log.i("item: ", item.toLowerCase());

        int resID = getResources().getIdentifier(item.toLowerCase(), "drawable", "package.name");

        Log.i("resid: ", String.valueOf(resID)); //will return 0 - im guessing this is where the problem is

        iv.setImageResource(resID);
    }

I used this as a guide Android, reference things in R.drawable. using variables? but none of the other solutions work for me, in fact they all gave me the same result (returning 0). I can provide more code if needed (just didn't want it to be bombastic). Thanks in advance!

`"package.name"` is wrong. use `getPackageName()`. [Here](http://stackoverflow.com/questions/22449692/set-background-drawable-resource-from-string) an example — Blackbelt, Oct 18 '16 at 11:04

getIdentifier() Returns 0 if no such resource was found. (0 is not a valid resource ID.)

and you should getPackageName() method of the context object which always return the correct package name.

if you will show your folder stracture and file's names i can help you to fix it.

btw, if you can get the drawable directly from the resource you can just use R.drawable.resName

It works T_T I'm so mad at myself for not figuring that out. Thank you so much! Yeah I know about the resource but unfortunately it wasn't an option for this app :) – Axelle Oct 20 '16 at 07:47
