My app was almost fully complete when I realized I needed to use fragments instead of activities in order to share the same Navigation Menu across all of the screens, so now I'm in the process of making all of my activity java code work in fragments. One issue that I can't seem to figure out is the spinner that changes the language. I have the English (Default), Spanish (ES), and French (FR) strings made and translated. When someone selects Spanish on the spinner I want it to change the app's locale to Spanish (es) & make a toast that says Language changed to Spanish!, etc. In order to do this, it must restart the fragment, correct? So begin settings fragment from settings fragment so the language updates? Right now, when I select an option from the spinner I can see that I selected it on the spinner, but nothing happens. No toast, no language, no refresh of the fragment, etc. All help is very much appreciated! Thank you!! I will post code below!
