How to get image resource ID by name?

Question

Android

Hello everyone, the task is this: to replace the picture in the Activity, having only the file name from the database.
I can't figure out how to get the resource id from the file name. I found a lot of options, but they don’t work, or I’m doing something wrong.
There was such an option

int imgRes = R.drawable.class.getField(itemImage).getInt(getResources());

itemImage is a string variable with the file name.
Maybe I'm not digging there at all and there is an easier option?

More or less like this. Maybe I messed up the settings.

int id = context.getResources().getIdentifier(itemImage, "drawable", context.getPackageName());
