title: Fading in text in Android using AnimationUtils.loadAnimation
body: <p>I would be very grateful if someone could explain to me why this works:</p>
  
  <pre><code>private void startAnimating() {
      TextView logo1 = (TextView) findViewById(R.id.Shizzle);   
          final Animation fade1 = new AlphaAnimation(0.0f, 1.0f);  
          fade1.setDuration(3000);
          logo1.startAnimation(fade1);
          }
  </code></pre>
  
  <p>But this doesn't work at all for me:</p>
  
  <pre><code>private void startAnimating() {
      TextView logo1 = (TextView) findViewById(R.id.Shizzle);   
          Animation fade1 = AnimationUtils.loadAnimation(this,R.anim.fade_in);  
      logo1.startAnimation(fade1);    
      }
  </code></pre>
  
  <p>The fade_in.xml associated with the above is:</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;set
      xmlns:android="http://schemas.android.com/apk/android"
      android:shareInterpolator="false"&gt;
      &lt;alpha
          android:fromAlpha="0.0"
          android:toAlpha="1.0"
          android:duration="3000"&gt;
      &lt;/alpha&gt;
  </code></pre>
  
  <p>Thanks for your help!
      </p>
