title: How to programmatically reference <string> in xml file in android
body: <p>I am new to android programming and wanna know this:</p>
  
  <p>I have 3 strings defined in the strings.xml file:
      <code>&lt;resources&gt;
      &lt;string name="one"&gt;First Click &lt;/string&gt;
      &lt;string name="two"&gt;Second Click &lt;/string&gt;
      &lt;string name="three"&gt;Third Click &lt;/string&gt;
      &lt;resources&gt;</code></p>
  
  <p>and a text view which displays the first string in the strings.xml file.
  i don't want to use   <code>settext("******")</code> to change the text of text view when the user
  clicks on a button.
  how can i make the textview switch to the text already defined in the strings.xml file, say from     </p>
