title: Can't make calculations using a mix of TextView and EditText
body: <p>I'm currently making a very simple math game. In this math game I want the player to solve easy equations. It looks like this: 9 * __ = 45, the player then fill in the correct number to solve the equation and then presses a Correct-button. If correct scores are added to the player.</p>
  
  <p>The empty space is an EditText and the others are TextViews. Because I use a mix of TextView &amp; EditText I need somehow to make a convertion for the program to be able to read and calculate. I've been reading like crazy and tried all kinds of different methods without success. How should I do to get around this?</p>
  
  <p>This is how my data looks like:</p>
