title: Retrieve button by findViewWithTag not working?
body: <p>In the onCreate() method of my class I make a grid of buttons, and give them tags to identify them, for example:</p>
  
  <pre><code>button.setTag("one four");
  </code></pre>
  
  <p>This is working fine. Now I want to make a new temporary button within a method, and I'm using this code:</p>
  
  <pre><code>String s = "one four";
  Object o = s;
  View view = new View(this);
  Button button = (Button)view.findViewWithTag(o); 
  </code></pre>
  
  <p>But button always comes out as "null". And I don't know why.</p>
