title: How to keep a radio button checked after closing the application - android studio
body: <p>I am new to coding in Android Studio and I just learned about Shared Prefrences.
  My teacher gave me an assignment to make a Radio Button Group (RadioGroup), that when you check one of the buttons, close the app, open it again, the button will remain checked.</p>
  
  <p>Just like you  would save an <code>EditText</code> answer with <code>SharedPrefrences</code>, I need  to save a <code>RadioButton</code> with <code>SharedPrefrences</code>.</p>
  
  <p>As I said  I am new to this, so please keep the answer simple :)</p>
  
  <p>--SOLVED-- Thank you all for answering! i found my solution thanks to your comments! :D</p>
