title: In Android Studio, how get popup of all methods a class can implement (and add them)?
body: <p>If I've created a class that implements another one (e.g. <code>class MyFragment extends Fragment</code>), when I start typing in the class, it is not giving me the code completion for parent methods. How do I get this to show up or get a popup that I can choose them from?</p>
  
  <p>For example, in <code>MyFragment</code>, typing <code>public void onCre</code> does not show anything. (But after typing the entire method, it compiles fine.)</p>
