title: Android: how to multiply values from EditText?
body: <p>Ok, first thing is that I am new in <code>Android</code> development, please do not shoot me for the question.</p>
  
  <p>So, I am developing an app yhat needs to multiply from 3 <code>EditTexts</code>:</p>
  
  <pre><code>resultsEditText
  amountEditText
  taxEditText
  </code></pre>
  
  <p>They are set with the same name in the <code>R.java</code>.  what I want is  the following:</p>
  
  <pre><code>amountEditText * taxEditText = resultsEditText
  </code></pre>
  
  <p>I have no idea in how to implement this, I have searched the internet and this site, which I use as a reference for all my Android development needs, and all the code I found doesnt work at all.  I dont know what else to do.  Thanks in advance!</p>
