title: Android AndEngine change text dynamically
body: <p>I am using custom font in andengine and when the user click that ui I need to change the color of my ui.Here is my code.</p>
  
  <pre><code>Text exit=new Text(250, 390, this.mPlokFont, "Exit");
  exit.setColor(255,0, 0, 255);  
  scene.attachChild(exit); 
  </code></pre>
  
  <p>but it doesn't work. My font :</p>
  
  <pre><code>mPlokFont = FontFactory.createFromAsset(this.mPlokFontTexture, this, "Plok.ttf", 16, true, Color.WHITE);
  </code></pre>
