title: How to create simple Android studio pop up window with EditText field for data insertion
body: <p>I've done a lot of search and there seems to be stuff only about error windows or strange menus/different activities. </p>
  
  <p>What I want is just a simple pop up window with an <code>EditText</code> field and an OK button. </p>
  
  <p>What should I use? How do I use it?</p>
  
  <p>Oh and... Is it possible to do this only with Java? (without .xml files)</p>
